By default, when you add the C1DropDown control to an application, the drop-down arrow, the ToggleButton, is visible. However, if you choose you can hide the drop-down arrow by setting the ShowButton property as in the following steps.
At Design Time in Blend
To hide the drop-down arrow, complete the following steps:
1. Click the C1DropDown control once to select it.
2. Navigate to the Properties window and clear the ShowButton check box.
This will hide the drop-down arrow on the control.
In XAML
To hide the drop-down arrow, add ShowButton="False" to the <c1:C1DropDown> tag so that it appears similar to the following:
<c1:C1DropDown Height="30" Name="c1DropDown1" Width="100" ShowButton="False" />
In Code
To hide the drop-down arrow, add the following code to your project:
Me.C1DropDown1.ShowButton = False
•C#
this.c1DropDown1.ShowButton = false;
This will hide the drop-down arrow on the control.
What You've Accomplished
Run the application. Observe that the drop-down arrow no longer appears on the C1DropDown control.
