Description

How to remove the field filters in the FilteringControl shown in the RadGridView's column filter popup.

Solution 1

To hide the two field filters, set the ShowFieldFilters property of the GridView column to false.

XAML

	<telerik:GridViewDataColumn ShowFieldFilters="False" />

Solution 2

To hide only one of the filters, use the Loaded event of the FilteringControl in order to access the corresponding visual elements. Then, set their Visibility to Collapsed.

C#

	static MainWindow()
	{
		EventManager.RegisterClassHandler(typeof(FilteringControl), FilteringControl.LoadedEvent, new RoutedEventHandler(OnFilteringControlLoaded));
	}

	private static void OnFilteringControlLoaded(object sender, RoutedEventArgs e)
	{
		var filteringControl = (FilteringControl)sender;
		var comboBoxes = filteringControl.ChildrenOfType<RadComboBox>();
		
		var logicalOperatorComboBox = comboBoxes.FirstOrDefault(x => x.Name == "PART_LogicalOperatorsComboBox");
		if (logicalOperatorComboBox != null)
		{
			logicalOperatorComboBox.Visibility = Visibility.Collapsed;
		}

		var filter2ComboBox = comboBoxes.FirstOrDefault(x => x.Name == "PART_Filter2ComboBox");
		if (filter2ComboBox != null)
		{
			filter2ComboBox.Visibility = Visibility.Collapsed;
		}

		var filter2Editor = filteringControl.ChildrenOfType<ContentControl>().FirstOrDefault(x => x.Name == "PART_Filter2ContentControl");
		if (filter2Editor != null)
		{
			filter2Editor.Visibility = Visibility.Collapsed;
		}
	}
