Adding Text to the Header

By default, the C1Expander control's header is empty. You can add text to the control's header by setting the Header property to a string in Blend, in XAML, or in code.

At Design Time in Blend

To set the Header property in Blend, complete the following steps:

Click the C1Expander control once to select it.
Under the Properties tab, set the Header property to a string (for example, "Hello World").

In XAML

To set the Header property in XAML, add Header="Hello World" to the <c1ext:C1Expander> tag so that it appears similar to the following:

XAML	Copy Code
<c1ext:C1Expander Header="Hello World" Width="150" Height="55">

In Code

To set the Header property in code, complete the following steps:

Add x:Name="C1Expander1" to the <c1ext:C1Expander> tag so that the control will have a unique identifier for you to call in code.
Enter Code view and add the following code beneath the InitializeComponent() method:

Visual Basic
Copy Code
C1Expander1.Header = "Hello World"

Visual Basic	Copy Code
C1Expander1.Header = "Hello World"

Run the program.
