Changing the Initial Expand State

By default, the C1Expander control's IsExpanded property is set to False, meaning that the control will appear in its collapsed state upon page load. If you'd prefer that the C1Expander control be expanded upon page load, you can set the IsExpanded property to True in the Properties window, in XAML, or in code.

At Design Time

To set the IsExpanded property to True, complete the following steps:

1.   Click the C1Expander control once to select it.

2.   In the Properties window,  locate the IsExpanded check box and then select it.

In XAML

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

<c1ext:C1Expander IsExpanded="True" Name="C1Expander1" Width="150" Height="55">

In Code

To set the IsExpanded property to True in code, complete the following steps:

1.   Enter Code view and add the following code beneath the InitializeComponent() method:

•      Visual Basic

C1Expander1.IsExpanded = True

•      C#

c1Expander1.IsExpanded = true;

2.   Run the program.
