allowing clicks on Button in ComboBoxItem when IsHitTestVisible is false

Question

Setting the IsHitTestVisible="false" has the effect of having the whole ComboBox's drop area unresponsive to clicks. The same goes for setting to true.

With a ComboBox I don't have to create any storyboard to make ComboBox animation like but I found this issue.

How can one make the ComboBoxItem area unclickable except for the button within?

Sounds like you should be creating a custom control that uses a popup window, that just looks like a combobox, however you can do what you wanted:

• Put your buttons inside a grid, inside a single RadComboBoxItem
• Set the grid background colour to 1% alpha so it is hit-test visible yet unseen
• Add a Grid_MouseLeftButtonUp event handlern to the grid
• In the handler set e.Handled to true so the mouse up is eaten

Make sure you close the combobox popup when you get your button presses.

Hope this helps.
