  Hi Team,
  I want a multi column combobox, for this i create a combobox and define gridview as RadcomboboxItem. It works fine, but I am unable to filter gridview. I want a multicolumn combobox, which can filter columns. I RadGridView1_SelectionChanged event to set selected value.
   Your Quick response will be highly appreciated.
  
  Following is Xmal Code:
  

  <telerik:RadComboBox Name="rcbNew" Grid.Row="0"

                            IsEditable="True" Height="25" Width="200">

              <telerik:RadComboBox.Items>

                  <telerik:RadComboBoxItem>

                      <telerik:RadComboBoxItem.Template>

                          <ControlTemplate>

                              <my1:RadGridView x:Name="RadGridView1" ShowGroupPanel="False" CanUserFreezeColumns="False"

                                               RowIndicatorVisibility="Collapsed" IsReadOnly="True"

                                               IsFilteringAllowed="False" ItemsSource="{Binding .}"

                                               Width="200" Height="150" SelectionChanged="RadGridView1_SelectionChanged" >

                              </my1:RadGridView>

                          </ControlTemplate>

                      </telerik:RadComboBoxItem.Template>

                  </telerik:RadComboBoxItem>

              </telerik:RadComboBox.Items>

          </telerik:RadComboBox>

  
  
  
  Here follwoing code:
  

       
  

  DependencyProperty currentSelectedValue = DependencyProperty.Register("rcbNewSelectedValue", typeof(Int32), typeof(Int32));
          // Constructor
  public GridinDropDown()

          {

              InitializeComponent();

              IList<Company> MyObject;

   

              MyObject = new List<Company>()

              {

                  new Company { Id=1, Name="Description1" },

                  new Company { Id=2, Name="Description2" },

                  new Company { Id=3, Name="Description3" },

                  new Company { Id=4, Name="Description4" }

              };

   

              this.DataContext = MyObject;

          }
  
  

  private void RadGridView1_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)

          {

              rcbNew.Text = ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Name;

              rcbNew.SetValue(currentSelectedValue, ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Id);// = ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Id;

              rcbNew.IsDropDownOpen = false;

          }
