MultiColumnComboBox DropDown Doesn't Close After Context Menu Is Opened

Updated on Sep 15, 2025

Environment

Product Version
Product	RadMultiColumnComboBox for WPF

Description

Setting the KeepDropDownOpen property of RadMultiColumnComboBox to False enables the auto closing feature of the drop down part of the control. However, opening a RadContextMenu for an element inside the dropdown is breaking the functionality. This means that clicking outside of the RadMultiColumnComboBox control won't close its drop down.

Solution

To resolve this, set the RestoreFocusToTargetElement property of the RadContextMenu control to True.

XAML

	<telerik:RadMultiColumnComboBox KeepDropDownOpen="False">
			<telerik:RadContextMenu.ContextMenu>
				<telerik:RadContextMenu RestoreFocusToTargetElement="True">
					<telerik:RadMenuItem Header="Copy"/>
				</telerik:RadContextMenu>
			</telerik:RadContextMenu.ContextMenu>
	</telerik:RadMultiColumnComboBox>
