1.  如何解决单击记录整行选中的问题
    
    View->OptionsBehavior->EditorShowMode 设置为：Click
2.  如何新增一条记录
    
    (1)、gridView.AddNewRow()
    
    (2)、实现 gridView\_InitNewRow 事件
3.  如何只显示主从表内的主表记录
    
    将gridview.OptionsDetail.EnableMasterViewMode 设置为False。这样就只显示主表数

    ![2012090816175344.jpg][]
    
    方法如下：
    
    //When no Records Are Being Displayed
    
    private void gridView1\_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)
    
    \{
    
    //方法一（此方法为GridView设置了数据源绑定时，可用）
    
        ColumnView columnView = sender as ColumnView; 
        BindingSource bindingSource = this.gridView1.DataSource as BindingSource; 
        if(bindingSource.Count == 0) 
        { 
            string str = "没有查询到你所想要的数据!"; 
            Font f = new Font("宋体", 10, FontStyle.Bold); 
            Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5); 
            e.Graphics.DrawString(str, f, Brushes.Black, r); 
        }
    
    //方法二（此方法为GridView没有设置数据源绑定时，使用，一般使用此种方 法）
    
        if (this._flag)
         { 
              if (this.gridView1.RowCount == 0)
              { 
                   string str = "没有查询到你所想要的数据!"; 
                   Font f = new Font("宋体", 10, FontStyle.Bold);
                   Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);
                   e.Graphics.DrawString(str, f, Brushes.Black, r); 
               } 
         }
10. 如何显示水平滚动条？或
    
    设置 this.gridView.OptionsView.ColumnAutoWidth = false;
    
    .....列表宽度自适应内容
    
    gridview1.BestFitColumns();

11. 如何定位数据位置

设置 this.gridView.MoveFirst() //定位到第一行；

设置 this.gridView.MoveLast() //定位到最后行

12. 设置成一次选择一行，并且不能被编辑

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

this.gridView1.OptionsBehavior.Editable = false;

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

13.如何显示行号

private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
            {
                e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
                if (e.Info.IsRowIndicator)
                {
                    if (e.RowHandle >= 0)
                    {
                        e.Info.DisplayText = (e.RowHandle + 1).ToString();
                    }
                    else if (e.RowHandle < 0 && e.RowHandle > -1000)
                    {
                        e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                        e.Info.DisplayText = "G" + e.RowHandle.ToString();
                    }
                }
    ｝

14.如何让各列头禁止移动？

设置 gridView1.OptionsCustomization.AllowColumnMoving = false;

15.如何让各列头禁止排序？

设置 gridView1.OptionsCustomization.AllowSort = false;

16.如何禁止各列头改变列宽？

设置 gridView1.OptionsCustomization.AllowColumnResizing = false;

17.拖动横向滚动条时固定某列

设置Columns，选择要固定的列。设置Fixed属性，可以选择：固定在左边、固定在右边、不固定。

![364809-20190809154834692-1915831776.png][]

19. 获取选定行,指定列单元格的内容

return gridView1.GetRowCellValue(pRows\[0\], ColumName).ToString ();

20. 分组显示

OptionsView>OptionsBehavior>AutoExpandAllGroups = True  
选择要分组的列，将GroupIndex属性设置为0

格式化数据

private void gvList\_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)  
\{  
if (this.gvList.FocusedColumn.FieldName == "passQty")  
\{  
string passQty = e.Value.ToString().Trim();  
int receiveQty = orderDetailList\[this.gvList.FocusedRowHandle\].qty;  
if (!JXType.IsIntBigThanZero(passQty))  
\{  
e.Valid = false;  
e.ErrorText = "合格数量必须为大于等于0小于等于接货数量的整数！";  
\}  
else  
\{  
if (int.Parse(passQty) > receiveQty)  
\{  
e.Valid = false;  
e.ErrorText = "合格数量必须为大于0小于等于接货数量的整数！";  
\}  
\}  
\}

22.合并表头

///初始化表格

using DevExpress.XtraGrid.Columns;  
using DevExpress.XtraGrid.Views.Base;  
using DevExpress.XtraGrid.Views.BandedGrid;  
using DevExpress.XtraEditors.Repository;  
private void InitGrid()  
\{  
// advBandedGridView1是表格上的默认视图，注意这里声明的是：BandedGridView  
BandedGridView view = advBandedGridView1 as BandedGridView;  
view.BeginUpdate(); //开始视图的编辑，防止触发其他事件  
view.BeginDataUpdate(); //开始数据的编辑  
view.Bands.Clear();

view.OptionsView.ShowColumnHeaders = false; //因为有Band列了，所以把ColumnHeader隐藏  
//添加列标题  
//添加列标题  
GridBand bandID = view.Bands.AddBand("ID");  
bandID.Visible = false; //隐藏ID列  
GridBand bandName = view.Bands.AddBand("姓名");  
GridBand bandSex = view.Bands.AddBand("性别");  
GridBand bandBirth = view.Bands.AddBand("出生日期");  
GridBand bandScore = view.Bands.AddBand("分数");  
GridBand bandMath = bandScore.Children.AddBand("数学");  
GridBand bandChinese = bandScore.Children.AddBand("语文");  
GridBand bandEnglish = bandScore.Children.AddBand("英语");  
GridBand bandSubTotal = bandScore.Children.AddBand("小计");  
GridBand bandRemark = view.Bands.AddBand("备注");

bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//这是合并表头居中显示  
view.EndDataUpdate();//结束数据的编辑  
view.EndUpdate(); //结束视图的编辑  
\}

具体可看

# dev gridcontrol 合并表头 #

![2012090816191918.gif][]

23. //动态添加列  
DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();  
Col1.FieldName = "name";  
Col1.Caption = "名字";  
Col1.Visible = false;  
Col1.VisibleIndex = gvCountry.Columns.Count;  
gvCountry.Columns.Add(Col1);

24。设置自动增加的行号

private void gridview\_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)  
\{

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;  
if (e.Info.IsRowIndicator)  
\{  
if (e.RowHandle >= 0)  
\{  
e.Info.DisplayText = (e.RowHandle + 1).ToString();  
\}  
else if (e.RowHandle < 0 && e.RowHandle > -1000)  
\{  
e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;  
e.Info.DisplayText = "G" + e.RowHandle.ToString();  
\}  
\}

｝

25.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、Advanced BandedView、LayoutView；共5种。

1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了  
2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角  
3）、Roll Angle 属性决定着 倾侧角度  
4）、指定数据源，显示数据：  
//显示数据  
private void showData(List<Employee > list)  
\{  
DataTable dt = new DataTable("OneEmployee");  
dt.Columns.Add("Caption", System.Type.GetType("System.String"));  
dt.Columns.Add("Department", System.Type.GetType("System.String"));  
dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte\[\]"));

for (int i = 0; i < list.Count; i++)  
\{  
DataRow dr = dt.NewRow();  
dr\["Caption"\] = list\[i\].Name;  
dr\["Department"\] = list\[i\].Department;  
string imagePath = @"D:\\C\#\\photos\\" + list\[i\].PhotoPath;  
dr\["PhotoName"\] = getImageByte(imagePath);  
dt.Rows.Add(dr);  
\}  
gridControl1.DataSource = dt;  
\}

//返回图片的字节流byte\[\]  
private byte\[\] getImageByte(string imagePath)  
\{  
FileStream files = new FileStream(imagePath, FileMode.Open);  
byte\[\] imgByte = new byte \[files.Length \];  
files.Read(imgByte, 0, imgByte.Length);  
files.Close();  
return imgByte;  
\}

26.检查数据的有效性

在gridview的ValidateRow事件中加入检查代码：  
\#region 检查数据  
private void gridView1\_ValidateRow(object sender, ValidateRowEventArgs e)  
\{  
GridView view = sender as GridView;  
view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)  
\{  
e.Valid = false;  
view.SetColumnError(view.Columns\["ReceiveDate"\], "必须指定日期");  
\}

27.设某一列文字和标题局中显示  
gridView1.Columns\[0\].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;  
gridView1.Columns\[0\].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

28.列表过滤条件多选

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

29.隔行换色的方法

this.gridView1.Appearance.OddRow.BackColor = Color.White; // 设置奇数行颜色 // 默认也是白色 可以省略  
this.gridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面绑定 同时使用有效  
this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 设置偶数行颜色  
this.gridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面绑定 同时使用有效

1.隐藏最上面的GroupPanel  
gridView1.OptionsView.ShowGroupPanel=false;

2.得到当前选定记录某字段的值  
sValue=Table.Rows\[gridView1.FocusedRowHandle\]\[FieldName\].ToString();

3.数据只读  
gridView1.OptionsBehavior.Editable=false;

4.不显示MasterDetailView  
gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel内容  
gridView1.GroupPanelText="柳生飘絮";

6.设置数据源:  
gridControl1.DataSource = dt;  
绑定每一列的FiledName--属性  
对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.

7.读写拷贝权限设置  
只读不可拷贝：  
ColumnViewOptionsBehavior.Editable = False

只读可拷贝:  
ColumnViewOptionsBehavior.Editable = True  
OptionsColumn.AllowEdit = True  
OptionsColumn.ReadOnly = True

可编辑:  
ColumnViewOptionsBehavior.Editable = True  
OptionsColumn.AllowEdit = True  
OptionsColumn.ReadOnly = False

8.模板列的设置:  
到Columns中，在他的属性中找到ColumnEdit.  
以LookUpEdit为例：  
首先从Designer左边菜单In-Place Editor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空.  
　　AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为True.  
　　SearchMode设置为OnlyInPopup.  
　　然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)  
　　最后我们还要在代码里面给Re1绑定数据源和显示项.  
Re1.DataSource = DALUse.Query("select fid,fname,fsex from dual").Tables\[0\];  
Re1.DisplayMember = "FSEX";  
Re1.ValueMember = "FNAME";

9.设某一列文字和标题局中显示  
gridView1.Columns\[0\].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;  
gridView1.Columns\[0\].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

10.去掉某一列上面的自动筛选功能(Filter)  
gridView1.Columns\[0\].OptionsFilter.AllowAutoFilter = false;  
gridView1.Columns\[0\].OptionsFilter.AllowFilter = false;  
gridView1.Columns\[0\].OptionsFilter.ImmediateUpdateAutoFilter = false;

11.设置冻结列(左冻结)  
gridView1.Columns\[0\].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

12.得到单元格数据(0行0列)  
string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns\[0\]);  
string ss = gridView1.GetRowCellValue(0, gridView1.Columns\[0\]);

13.设置单元格数据(将0行0列的单元格赋值123)  
gridView1.SetRowCellValue(0, gridView1.Columns\[0\], "123");

13.手动添加dev的列  
DevExpress.XtraGrid.Columns.GridColumn Col1=new DevExpress.XtraGrid.Columns.GridColumn ();  
Col1.FieldName="FID";  
Col1.Visible=true;  
Col1.VisibleIndex=gridView1.Columns.Count;  
gridView1.Columns.Add(Col1);

14.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator

private void gridview\_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)  
\{  
if (e.Info.IsRowIndicator && e.RowHandle >= 0)  
e.Info.DisplayText = (e.RowHandle + 1).ToString();  
\}

15.删除: (修改了dgvdel里的datagridviewdel方法)  
public static void datagridviewdel\_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)  
\{  
if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)  
\{  
int iSelectRowCount = Mydgv.SelectedRowsCount;  
if (iSelectRowCount > 0)  
\{  
Mydgv.DeleteSelectedRows();  
\}  
\}  
\}  
  
16. 新增: (对于新增,其本身的AddNewRow方法就可以做到)  
private void btn\_add\_Click(object sender, EventArgs e)  
\{  
gridView1.AddNewRow();  
\}  
具体如果对于新加行还有什么特别的设置,可以在它gridView1\_InitNewRow事件中填写:  
private void gridView1\_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)  
\{  
ColumnView View = sender as ColumnView;  
View.SetRowCellValue(e.RowHandle, View.Columns\[0\], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns\[0\])); //复制最后一行的数据到新行

View.SetRowCellValue(e.RowHandle, View.Columns\[1\], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns\[1\])); //复制最后一行的数据到新行

17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以)

18.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、Advanced BandedView、LayoutView；共5种。  
1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了  
2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角  
3）、Roll Angle 属性决定着 倾侧角度  
4）、指定数据源，显示数据：  
//显示数据  
private void showData(List<Employee > list)  
\{  
DataTable dt = new DataTable("OneEmployee");  
dt.Columns.Add("Caption", System.Type.GetType("System.String"));  
dt.Columns.Add("Department", System.Type.GetType("System.String"));  
dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte\[\]"));

19.检查数据的有效性  
在gridview的ValidateRow事件中加入检查代码：  
\#region 检查数据  
private void gridView1\_ValidateRow(object sender, ValidateRowEventArgs e)  
\{  
GridView view = sender as GridView;  
view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)  
\{  
e.Valid = false;  
view.SetColumnError(view.Columns\["ReceiveDate"\], "必须指定日期");  
\}

\}  
\#endregion  
调用gridview.UpdateCurrentRow()方法执行检查

最常用的DevExpress Winform 4个代码片段：

一 、GridControl的删除操作

private void rILinkEditInfoDel\_Click(object sender, EventArgs e)  
\{  
if (XtraMessageBox.Show("请确定是否删除当前记录？", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)  
\{  
DataRow row = gvInfos.GetDataRow(gvInfos.FocusedRowHandle);  
delByCode(row\["Code"\].ToString());  
XtraMessageBox.Show("操作成功！");  
\}  
\}

二、绑定非数据表中列

Hashtable ht = new Hashtable();

private void gridView6\_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)  
\{  
GridView View = sender as GridView;  
if (e.RowHandle >= 0)  
\{  
object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns\["needAlert"\]);  
if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns\["Value"\]) != DBNull.Value)  
\{  
decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns\["Value"\]));  
object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns\["MinValue"\]);  
object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns\["MaxValue"\]);  
if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")  
\{  
decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns\["MinValue"\]));  
decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns\["MaxValue"\]));  
if (gridColumn2 > AverValue || AverValue > gridColumn1)  
\{  
if (!ht.ContainsKey("pic"))  
ht.Add("pic", GetImage(1));  
e.Value = ht\["pic"\];  
\}  
\}  
\}  
\}  
\}

/// <summary>  
/// 由资源文件获取图片  
/// </summary>  
/// <param name="key"></param>  
/// <returns></returns>  
byte\[\] GetImage(int key)  
\{  
Image img = DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.\{0\}.gif", key.ToString()), typeof(RiverInfos).Assembly);  
return DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img, ImageFormat.Gif);  
\}

/// <summary>  
/// 动态根据条件设置行样式  
/// </summary>  
/// <param name="sender"></param>  
/// <param name="e"></param>  
private void gridView6\_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)  
\{  
GridView View = sender as GridView;  
if (e.RowHandle >= 0)  
\{  
object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns\["needAlert"\]);  
if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns\["Value"\]) != DBNull.Value)  
\{  
decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns\["Value"\]));  
object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns\["MinValue"\]);  
object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns\["MaxValue"\]);  
if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")  
\{  
decimal gridColumn2 = Convert.ToDecimal(MinValue);  
decimal gridColumn1 = Convert.ToDecimal(MaxVlaue);  
if (gridColumn2 > AverValue || AverValue > gridColumn1)  
\{  
e.Appearance.ForeColor = Color.Red;  
e.Appearance.BackColor = Color.LightGray;  
\}  
\}  
\}  
\}  
\}

三、GridControl 中颜色选择控件

private void gvMapColor\_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)  
\{  
GridView view = sender as GridView;  
DataView dv = view.DataSource as DataView;  
if (e.IsGetData)  
\{  
string strVal = dv\[e.ListSourceRowIndex\]\["Color"\].ToString();  
if (strVal != "")  
\{  
//e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal);  
e.Value = Common.HexToColor(strVal);  
\}  
\}  
else  
\{  
//Color colorVal = DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString());  
Color colorVal = (Color)e.Value;  
dv\[e.ListSourceRowIndex\]\["Color"\] = Common.RGB\_HEX(colorVal.ToArgb());  
\}  
\}

四、关于 GridControl 验证示例

/\*\* <summary>  
/// 初始化GridView，绑定数据  
/// </summary>  
/// <param name="parentId"></param>  
private void GridViewBindData(string parentId)  
\{  
this.gridView1.Columns.Clear();  
this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);  
this.gridCArea.DataSource =this.FDs.Tables\[0\].DefaultView;

this.gridView1.Columns\["id"\].VisibleIndex = -1;  
this.gridView1.Columns\["childCounts"\].VisibleIndex = -1;

this.gridView1.Columns\["reg\_id"\].Caption = "区划编号";  
this.gridView1.Columns\["reg\_name"\].Caption = "区划名称";  
this.gridView1.Columns\["parent\_id"\].Caption = "父区划编号";  
this.gridView1.Columns\["reg\_desc"\].Caption = "区划描述";  
this.gridView1.Columns\["parent\_id"\].ImageIndex =1;  
this.gridView1.Columns\["reg\_desc"\].ImageIndex = 0;

RepositoryItemTextEdit textEditReg\_Id = new RepositoryItemTextEdit();  
textEditReg\_Id.Mask.EditMask =parentId+"\\\\d\{2,3\}";  
textEditReg\_Id.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.Regular;

this.gridView1.Columns\["reg\_id"\].ColumnEdit = textEditReg\_Id;

this.gridView1.Columns\["reg\_desc"\].ColumnEdit = new RepositoryItemMemoExEdit();

TreeListNode node = this.treelArea.FocusedNode.ParentNode;  
string fid = node==null?"0":node.GetValue("RegID").ToString().Trim();  
DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);  
RepositoryItemLookUpEdit lookUEParent\_Id = new RepositoryItemLookUpEdit();  
lookUEParent\_Id.Columns.Add(new LookUpColumnInfo("reg\_id", 40, "区划编号"));
