Opening the Drop-Down List on MouseOver

By default, the C1ComboBox control's drop-down list is only revealed when a user clicks the drop-down arrow. In this topic, you will write code that will cause the drop-down list to open whenever a user hovers over the control. This topic assumes that 1) you have already added a C1ComboBox control with at least one item to your project and 2) you are working in Expression Blend.

Complete the following:

1.   Click the C1ComboBox control to select it.

2.   In the Properties window, click the Events button   to reveal the control's list of events.

3.   Double-click inside of the MouseEnter text box. This will add the C1ComboBox_MouseEnter event handler to Code view.

4.   Add the following code to the C1ComboBox1_MouseEnter event handler:

      Visual Basic

      C#

5.   Run the program.

 This Topic Illustrates the Following:

With the program running, hover over the C1ComboBox control with your cursor. Observe that the drop-down list appears when you hover over the control. The drop-down list will stay open until you either select an item or click outside of the control.
