Hi,

 Please follow the approach in this troubleshooting article in order to resolve your issue. If this does not help I would asked you to test with the latest version.  It would be even better to send me a sample project showing the issue in order to investigate it.

Kind regards,

hi,

I tried with latest telerik build "RadControls_for_WPF_2012_2_1001_DEV_hotfix" but still the same problem. There is no any code for column filter, filtering is a default feature in Gridview control.

Hello,

The distinct values are shown in a standard ListBox. May I ask you to clarify whether you modified any styles / themes, etc.? Do you have an additional style targeting ListBox defined?

I look forward to hearing from you.

hi,

I removed theme it is working fine with me. Please let me know what other things will effect if i use 3rd party themes in my project?

[Yoan]

Hi,

This depends on what controls are using your theme. For example if your theme has style for a ListBox it will apply for the ListBox in the GridView's Filter and for all others ListBoxes, but this depends on how you define the styles. Please be stick to our documentation.

How can i find "PART_DistinctValueList" the grid distincit list from the code behind not from the xaml??

Hi,

Even though that approach is not very correct, here is how you can find the listbox:

1. Derive from our default filtering control:

using System;
using System.Linq;
using System.Windows.Controls;
using Telerik.Windows.Controls.GridView;

namespace RadGridView_WPF_AR_11
{
    public class FilteringControlEx : FilteringControl
    {
        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            var listBox = this.GetTemplateChild("PART_DistinctValuesList") as ListBox;

            if (listBox != null)
            {
                // Do something
            }
        }
    }
}

2. Tell your column(s) to use this new filtering control:

<Window x:Class="RadGridView_WPF_AR_11.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:my="clr-namespace:RadGridView_WPF_AR_11"
        Title="MainWindow" Height="700" Width="700">
    <Window.Resources>
        <my:MyViewModel x:Key="MyViewModel"/>
    </Window.Resources>
    <Grid DataContext="{StaticResource MyViewModel}">
        <telerik:RadGridView Grid.Row="0"
                             Name="clubsGrid"
                             ItemsSource="{Binding Clubs}"
                             AutoGenerateColumns="False"
                             Margin="5">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
                    <telerik:GridViewDataColumn.FilteringControl>
                        <my:FilteringControlEx />
                    </telerik:GridViewDataColumn.FilteringControl>
                </telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

I have attached a project.
