<sdk:TreeViewItem Header="Science">
<sdk:TreeViewItem Header="Physics" />
<sdk:TreeViewItem Header="Chemistry" />
<sdk:TreeViewItem Header="Math" />
<sdk:TreeViewItem Header="Biology" />
</sdk:TreeViewItem>

Button control is mostly used to submit user data or perform some activity (or action) based on click of the button. This is one of the most frequently used controls in the Silverlight application.

How to display a button on the page in Silverlight.

Code

<Button Content="Submit" x:Name="btnTest" Canvas.Top="15" Canvas.Left="50"/>
<Button x:Name="btnTestAgain" Canvas.Top="55" Canvas.Left="50" Width="150" Height="30">
<Button.Content>
<Canvas>
<Ellipse Width="125" Height="25" Canvas.Left="-60" Canvas.Top="-13" Fill="Aqua" />
<TextBlock Text="Button Text" Canvas.Left="-30" Canvas.Top="-10"/>
</Canvas>
</Button.Content>
</Button>

Note that Button control doesn’t have a Text property but it has Content property that let us display any object as Button content, it can be text, an image or any other content.

In the above code snippet, first we have a Button control whose Content is specified as “Submit” text. In the other Button we have specified Button.Content as the Ellipse and TextBlock that displays the shape and Text as Button content.
