Opening and Closing Delays
The RadContextMenu allows you to specify a delay for the closing and opening actions of its child items. This means that you make the RadContextMenu wait for a specific amount of time before opening or closing a sub menu. In order to specify these delays you can set the ShowDelay and HideDelay properties. They are of type Duration and have the following format in XAML "0:0:0.00".
Here is an example of a RadContextMenu with a delay before opening a sub menu equal to one second and a delay before closing a sub menu also equal to one second.
Set Opening and Closing Delays
<telerik:RadMenu VerticalAlignment="Top"
ShowDelay="0:0:1"
HideDelay="0:0:1">
</telerik:RadMenu>
Keep the Context Menu Open
By default, the RadContextMenu closes when the user clicks a menu item. Set StaysOpen to True when the menu should remain open after an item is selected.
