I just added a style to my app (in appStyles.xaml) to hide the gridview distinct filter. The style is working but in design view of pages & windows i get the following errors:

This is what the resource declarations in the appStyles.xaml are:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<br>    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"<

br> xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"<br

>    xmlns:Telerik_Windows_Controls_MaskedTextBox="clr-namespace:Telerik.Windows.Controls.MaskedTextBox;assembly=Telerik.Windows.Controls.Input"  >

Here's how i'm the style for the FilteringControl:

<Style TargetType="{x:Type telerik:FilteringControl}" > <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type telerik:FilteringControl}"> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Margin="{TemplateBinding Margin}"> <Border BorderBrush="White" BorderThickness="1" Background="{TemplateBinding Background}"> <Grid> <StackPanel HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" MaxWidth="350" Margin="{TemplateBinding Padding}" MinWidth="200" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <StackPanel x:Name="PART_DistinctFilter" Visibility="{TemplateBinding DistinctFiltersVisibility}"> <CheckBox x:Name="PART_SelectAllCheckBox" Visibility="Collapsed" Content="Select All" IsChecked="{Binding SelectAll, Mode=TwoWay}" Margin="0,2" telerik:LocalizationManager.ResourceKey="GridViewFilterSelectAll"> <telerik:StyleManager.Theme> <telerik:MetroTheme /> </telerik:StyleManager.Theme> </CheckBox> <ListBox x:Name="PART_DistinctValuesList" ItemsSource="{Binding DistinctValues}" ScrollViewer.HorizontalScrollBarVisibility="Auto"

Here's from a window:

Not sure if i need to qualify the FilteringControl style with something or add another xmlns reference to the styles. Thanks

Hello Nk,

Thank you for sharing this snippet with us! I have just checked the modified FilteringControl style, however everything works fine by my side. Will you please check the attached project and let me know how it differs from yours? If the problem still persists feel free to modify it and send it back to us in a new support ticket where we can see what might be wrong.

Hi Nk,

Indeed the problem is related to the target framework in your project! I suggest that for flexibility you have replaced the grid prefix with the Telerik schema (telerik:), however under WPF 3.5 you should use the initial one and the full namespace in order to avoid such errors, something like the following:

xmlns:grid="clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView"

<grid:FilterOperatorConverter/>

Furthermore I have updated the previous project and now everything works as expected in WPF 3.5.

All the best,
