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.

<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.

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; 
    } 
}
