Remarks

WebBrowserBrush is a type of Brush object similar to a VideoBrush. However, instead of painting an area with video content, it paints an area with HTML content. This HTML content is provided by a WebBrowser control. Just like the other brush types, you can use a WebBrowserBrush to paint the following:

NoteNote:

You can only use WebBrowserBrush in a Silverlight 4 or later out-of-browser application or in a Silverlight 5 in-browser trusted application.

To use a WebBrowserBrush, you do the following:

  1. Create a WebBrowser control and set its Source property.

  2. Apply the WebBrowserBrush to the object that you want to paint.

  3. Set the WebBrowserBrush object's SourceName property to the name of the WebBrowser that you created.

If the content in the WebBrowser changes, you must call the Redraw method to update the WebBrowserBrush.

WebBrowserBrush can only be used in applications that run outside the browser. If you use it in an application that runs in the browser, WebBrowserBrush is transparent and does not contain placeholder content.

Examples

The following example shows how to use a WebBrowserBrush control. In this example, the WebBrowserBrush updates its content when the user moves the mouse.

Private Sub LayoutRoot_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Input.MouseEventArgs)
    WBB1.Redraw()
End Sub
private void LayoutRoot_MouseMove(object sender, MouseEventArgs e)
{
    WBB1.Redraw();
}
<StackPanel x:Name="LayoutRoot" Background="Blue" MouseMove="LayoutRoot_MouseMove">
    <WebBrowser Name="WB1" Source="Hello.html" Height="150" Width="150" />
    <Rectangle Height="150" Width="150" >
        <Rectangle.Fill>
            <WebBrowserBrush SourceName="WB1" Opacity=".5" x:Name="WBB1"/>
        </Rectangle.Fill>
    </Rectangle>
</StackPanel>
