Fixing filter dropdown width

[Avi]

Hi Support,
In my grid view I am displaying a large strings in one column, SO when user tries to filter it,Filter Drop down goes out ot the windows frame,
SO I just want to fix filter drop down width,  I tried the XAML below , but with no help.

  <UserControl.Resources>
        <Style TargetType="telerik:FilteringControl" x:Key="RowFilteringWidth">
            <Setter Property="MaxWidth" Value="220"/>
        </Style>
    </UserControl.Resources>

<telerik:RadGridView Grid.Row="1"
                             CanUserSelect="False"
                             ItemsSource="{Binding DepositCollection}"
                             ScrollViewer.VerticalScrollBarVisibility="Auto"
                             SelectedItem="{Binding SelectedDeposit, Mode=TwoWay}"
                             Visibility="{Binding HasDepositData, Converter={StaticResource booleanToVisibilityConverter}}"
                             DataContext="{StaticResource RowFilteringWidth}"
                             >

Hello Avi,

Indeed when there is not enough space around RadGridView the FilteringControl is being clipped. 
Everything in your style seems to work correctly, however it is not assigned on the right place. 
A style targeted at RadGridView's FilteringControl can be assigned on a column not on the RadGridView's DataContext and everything should work as expected:

<telerik:GridViewDataColumn FilteringControlStyle="{StaticResource RowFilteringWidth}" DataMemberBinding="{Binding LastName}" Header="Last Name"/>

If you mark this style as an implicit through removing the x:Key attribute it will be applied to all columns in RadGridView. I am not quite sure how you defined the columns, however the approach in code-behind is the same: 

column.FilteringControlStyle = this.Resources["RowFilteringWidth
"] as Style;

Furthermore in our online documentation you will find a troubleshooting article which might be of help, follow this link.
