I created a custom filter.  I know that when you click outside of the filter control, it will close the filter.  I want to add a button that will close the filter control, but I didn't find anything.

I did this:

private void Image_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    try
    {
        ((this.Parent as Control).Parent as System.Windows.Controls.Primitives.Popup).IsOpen = false;
    }
    catch (Exception)
    {
    }
}

For some reason ParentOfType<System.Windows.Controls.Primitives.Popup>() always return null.

hello 
i think this code can help you 
private void btnclose_Click(object sender, RoutedEventArgs e)
        {
            FilteringDropDown down = Telerik.Windows.Controls.UIElementExtensions.ParentOfType<FilteringDropDown>(this);
            if (down != null)
            {
                down.IsDropDownOpen = false;
            }
        }
