Silverlight中d出自定义模态窗口
1. 建立Child窗口类
DemoChilDWindow前台代码：
<basics:ChilDWindow x:Class="System.windows.Controls.Samples.DemoChilDWindow"

<button Content="OK" Click="OKbutton_Click" WIDth="75" Height="23" HorizontalAlignment="Right" margin="0,79,0" GrID.Row="2" />
</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>

private voID OKbutton_Click(object sender,RoutedEventArgs e)
{
this.DialogResult = true;
}

private voID Cancelbutton_Click(object sender,RoutedEventArgs e)
{
this.DialogResult = false;
}
}
}
2. 调用

using System.linq;
namespace System.windows.Controls.Samples
{

[Sample("ChilDWindow",DifficultyLevel.Basic)]
[category("ChilDWindow")]
public partial class Childwindowsample : UserControl
{

/// Keeps an instance of a ChilDWindow that will be shown when a button is clicked.
/// </summary>
private DemoChilDWindow dcw;
/// <summary>

/// </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>

private voID Dcw_Closed(object sender,EventArgs e)
{
dialogResult.Text = dcw.DialogResult.ToString();
}

private voID button_Click(object sender,RoutedEventArgs e)
{
dcw.@R_502_5979@ = @R_502_5979@Text.Text;
dcw.DataContext = (from p in Photograph.GetPhotographs()
where p.name.Equals((thumbs.SelectedItem as Photograph).name)
select p).First().Image;
dcw.Show();
}
}
}
