Hello Jason,

May I ask you some questions in order to better assist you? Can you let me know what you mean by "I've turned off the filtering panel"? Have you made any modifications to the FieldFilterControl's ControlTemplate? If so, may I ask you to share them so that I can better understand the described scenario?

As for the TabStopMode, indeed this is a property of the column and is applied to the GridViewCell elements. However, the GridView FieldFilterControl which is responsible for filtering when the FilteringMode is FilterRow, is inside the GridViewHeaderCell element.

I am looking forward to your reply.

Hi, yes, I did modify the field filter control template as such:

<Style x:Key="FieldFilterDropDownButtonStyle" TargetType="telerik:RadDropDownButton">

<Setter Property="IsOpen" Value="false"/>

<Setter Property="BorderThickness" Value="1"/>

<Setter Property="HorizontalContentAlignment" Value="Center"/>

<Setter Property="VerticalContentAlignment" Value="Center"/>

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="telerik:RadDropDownButton">

<Grid>

<ContentPresenter x:Name="Content"

ContentTemplate="{TemplateBinding ContentTemplate}"

Content="{TemplateBinding Content}"

Margin="{TemplateBinding Padding}"

HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"

VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>

<Popup x:Name="DropDownPopup" mat:ThemeEffectsHelper.IsAcrylic="True">

<Border x:Name="DropDownPopupBorder" Background="{telerik1:FluentResource ResourceKey=AlternativeBrush}">

<ContentPresenter x:Name="DropDownPopupContent"

ContentTemplate="{TemplateBinding DropDownContentTemplate}"

Content="{TemplateBinding DropDownContent}"

DataContext="{TemplateBinding DataContext}"

HorizontalAlignment="Stretch"

VerticalAlignment="Stretch"/>

</Border>

</Popup>

</Grid>

<!--<ControlTemplate.Triggers>

<Trigger SourceName="DropDownPopup" Property="mat:ThemeEffectsHelper.IsAcrylic" Value="True">

<Setter TargetName="DropDownPopupBorder" Property="Background" Value=

"{Binding Source={StaticResource AlternativeBrushProxy}, Path=ProxyValue, Converter={StaticResource OpacityConverter}, ConverterParameter=128}"

/>

</Trigger>

</ControlTemplate.Triggers>-->

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

<ControlTemplate x:Key="FieldFilterControlTemplate" TargetType="grid:FieldFilterControl">

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}">

<Grid x:Name="PART_MainGrid">

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<ContentControl x:Name="PART_FilterEditorContentControl" Margin="3 0" IsEnabled="{Binding EditorIsEnabled}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch"/>

<!--<telerik:RadDropDownButton x:Name="PART_DropDownButton" Grid.Column="1" Style="{StaticResource FieldFilterDropDownButtonStyle}" KeepOpen="False" DropDownIndicatorVisibility="Collapsed">

<Border Cursor="Hand" Background="Transparent" Padding="2 0 5 0">

<Grid Width="12" Height="11" Margin="2">

<telerik:RadGlyph FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="{TemplateBinding Foreground}" Glyph="{StaticResource GlyphFilterSmall}"/>

<telerik:RadGlyph

FontSize="16"

HorizontalAlignment="Center"

VerticalAlignment="Center"

Foreground="{telerik1:FluentResource ResourceKey=AccentFocusedBrush}"

Visibility="{Binding FunnelFillVisibility}"

Glyph="{StaticResource GlyphFilterSmall}"/>

</Grid>

</Border>

<telerik:RadDropDownButton.DropDownContent>

<ListBox x:Name="PART_FilterOperatorsListBox"

Background="#01FFFFFF"

ItemsSource="{Binding AvailableOperatorViewModels}"

SelectedItem="{Binding SelectedOperatorViewModel, Mode=TwoWay}"/>

</telerik:RadDropDownButton.DropDownContent>

</telerik:RadDropDownButton> -->

</Grid>

</Border>

</ControlTemplate>

<Style x:Key="FieldFilterControlStyle" TargetType="grid:FieldFilterControl">

<Setter Property="Template" Value="{StaticResource FieldFilterControlTemplate}"/>

<Setter Property="BorderBrush" Value="{telerik1:FluentResource ResourceKey=BasicSolidBrush}"/>

<Setter Property="BorderThickness" Value="0 0 1 1"/>

<Setter Property="Padding" Value="0 1"/>

<Setter Property="MinHeight" Value="31"/>

<Setter Property="FontWeight" Value="Normal"/>

<Setter Property="telerik:TouchManager.TouchMode" Value="None"/>

</Style>

<Style TargetType="grid:FieldFilterControl" BasedOn="{StaticResource FieldFilterControlStyle}"/>

I also, interrupted the EditorCreatedEvent to hide the "Match Case" button, and the FilterOperatorsLoadingEvent to set default filter values:

private void gridView_FieldFilterEditorCreated2(object sender, Telerik.Windows.Controls.GridView.EditorCreatedEventArgs e)

{

//get the StringFilterEditor in your RadGridView

var stringFilterEditor = e.Editor as Telerik.Windows.Controls.Filtering.Editors.StringFilterEditor;

if (stringFilterEditor != null)

{

stringFilterEditor.MatchCaseVisibility = Visibility.Collapsed;

//stringFilterEditor.

//stringFilterEditor.Loaded += new RoutedEventHandler(stringFilterEditor_Loaded);

stringFilterEditor.Loaded += (s1, e1) =>

{

var textBox = e.Editor.ChildrenOfType<TextBox>().Single();

textBox.BorderBrush = Brushes.Transparent;

//textBox.Margin = new Thickness(0, 0, 5, 0);

textBox.MinWidth = 0;

textBox.TextChanged += (s2, e2) =>

{

textBox.GetBindingExpression(TextBox.TextProperty).UpdateSource();

textBox.Focus();

};

}

((Telerik.Windows.Controls.Filtering.Editors.StringFilterEditor)sender).ChildrenOfType<System.Windows.Controls.Primitives.ButtonBase>().ToArray()[1].Visibility = Visibility.Collapsed;

//}

private void OnRadGridViewFilterOperatorsLoading(object sender, Telerik.Windows.Controls.GridView.FilterOperatorsLoadingEventArgs e)

{

if(e.Column.UniqueName.Contains("Type"))
