在上面在预览中显示模板frx文件的内容，如果要是能动态设置或者是显示一些内容，应该怎样传递。

## 实现 ##

首先在report的设计窗口上添加一个字体控件，Name属性为 Text7

在打印按钮的点击事件中

private void button2_Click(object sender, EventArgs e)
            {
               
                //获取项目目录
                string baseDir = System.Windows.Forms.Application.StartupPath;
                //拼接模板文件目录
                var reportFile = Path.Combine(baseDir, "1.frx");
                //生成report对象
                report1 = new FastReport.Report();
                //先清理一下
                report1.Clear();
                //然后加载模板文件
                report1.Load(reportFile);
                //找到 Name属性为 Text7的控件
                var t = report1.FindObject("Text7") as TextObject;
                if (t != null)
                {
                    //修改控件值
                    t.Text = "霸道赋值";
                }
                //绑定预览控件 不然会弹出新的窗口
                this.report1.Preview = this.previewControl1; 
                //显示预览窗口
                report1.Prepare();
                report1.ShowPrepared();
            }
