Hi,
  In my design ,I have a grid ,one of the column of the grid is combobox control.
 In the combo box- drop down, I have binded Customer ID and CustomerName using EditorStyle.
 The issue is the drop down list the Items in ascending order of the CustomerID ,But I need to display the items in Descending order of CustomerName .Is there any property to achieve it?  Kindly help us to solve the problem.
Below is the Code snippet:

<TelerikGrid:GridViewComboBoxColumn x:Name="CmbItm" Width="2*" IsComboBoxEditable="True" IsFilterable="True"
         DataMemberBinding="{Binding CustomerID}" UniqueName="Customer_Vendor"
         DisplayMemberPath="CustomerName" Header="Customer/Vendor"
         SelectedValueMemberPath="CustomerID"                                                                                                                              
          ItemsSource="{Binding Path=Customer,    Source={StaticResource journalentryViewModel}}">
                <TelerikGrid:GridViewComboBoxColumn.CellStyle>
                            <Style TargetType="TelerikGrid:GridViewCell">
                                        <Setter Property="Height" Value="19"/>
                                    </Style>
                                </TelerikGrid:GridViewComboBoxColumn.CellStyle>

Hello Parameswari,

RadComboBox cannot sort its items, but if you sort its items source the control will display the items in the correct order.

All the best,
