1.建立Child窗口类

**DemoChildWindow****前台代码：**

<basics:ChildWindow x:Class="System.Windows.Controls.Samples.DemoChildWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:basics="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"

xmlns:dataform="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data.DataForm.Toolkit"

Width="400" Height="300"

Title="ChildWindowSample">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

<ComboBox.ItemTemplate>

</StackPanel>

</DataTemplate>

</ComboBox.ItemTemplate>

</ComboBox>

</Grid>

</StackPanel>

</Grid>

</basics:ChildWindow>

**DemoChildWindow****后台代码**

namespace System.Windows.Controls.Samples

///<summary>

/// Sample ChildWindow for demonstration purposes.

///</summary>

public partial class DemoChildWindow : ChildWindow

///<summary>

/// Initializes a DemoChildWindow.

///</summary>

public DemoChildWindow()

InitializeComponent();

optionsStack.DataContext = this;

///<summary>

/// Handles the Click event of the OK button.

///</summary>

///<param name="sender">OK Button.</param>

///<param name="e">Event arguments.</param>

\[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode", Justification = "Used by event defined in Xaml.")\]

private void OKButton\_Click(object sender, RoutedEventArgs e)

this.DialogResult = true;

///<summary>

/// Handles the Click event of the Cancel button.

///</summary>

///<param name="sender">Cancel button.</param>

///<param name="e">Event arguments.</param>

\[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode", Justification = "Used by event defined in Xaml.")\]

private void CancelButton\_Click(object sender, RoutedEventArgs e)

this.DialogResult = false;

2.调用

using System.ComponentModel;

using System.Linq;

namespace System.Windows.Controls.Samples

///<summary>

/// Sample page demonstrating the ChildWindow.

///</summary>

\[Sample("ChildWindow", DifficultyLevel.Basic)\]

\[Category("ChildWindow")\]

public partial class ChildWindowSample : UserControl

///<summary>

/// Keeps an instance of a ChildWindow that will be shown when a button is clicked.

///</summary>

private DemoChildWindow dcw;

///<summary>

/// Initializes a new instance of the ChildWindowSample class.

///</summary>

public ChildWindowSample()

InitializeComponent();

dcw = new DemoChildWindow();

dcw.Closed += new EventHandler(Dcw\_Closed);

thumbs.ItemsSource = from p in Photograph.GetPhotographs()

orderby p.Name

select p;

thumbs.SelectedIndex = 0;

///<summary>

/// Handles the "Closed" event of the ChildWindow.

///</summary>

///<param name="sender">Child Window.</param>

///<param name="e">Event Arguments.</param>

private void Dcw\_Closed(object sender, EventArgs e)

dialogResult.Text = dcw.DialogResult.ToString();

///<summary>

/// Handles clicking the "Show" button.

///</summary>

///<param name="sender">Clicked Button.</param>

///<param name="e">Event Arguments.</param>

\[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1811:AvoidUncalledPrivateCode", Justification = "Used by event defined in Xaml.")\]

private void Button\_Click(object sender, RoutedEventArgs e)

dcw.Title = titleText.Text;

dcw.DataContext = (from p in Photograph.GetPhotographs()

where p.Name.Equals((thumbs.SelectedItem as Photograph).Name)

select p).First().Image;

dcw.Show();
