(RadGridView + Popup Filter Control) Hide the additional fielfilter

[Matthieu]

Hi team,

I am looking for a simply way to hide / remove the additional Fieldfilter in the Filter Control (Popup) of a RadGridView. Is it possible to do this whithout creating a custom column or a complete custom control ?

I just to keep the distinct filter and the first FieldFilter

Thank you, have a nice day.

Regards

Hellо Matthieu,

RadGridView provides API that allows hiding the field filters, but this will hide both fields. This is done through the ShowFieldFilters property of the GridView columns.

There is no property to hide only one of the fields, but you can achieve this requirement with the following code-behind.

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;
	}
}

I hope that helps.

Wouhaou ! That's perfect, exactly what I was looking for. I would not be able to do that on my own.

Thank you,

Best regards
