CellEditTemplate Element

[Murat]

I want to use element "RadComboBox1" element in code. How can i do that.
I try at Q3 2011 WPF 4.0

var gridView= RadGridView1.Columns[0].CellEditTemplate.FindName("RadComboBox1", RadGridView1);

but i get "This operation is valid only on elements that have this template applied" error.

<telerik:RadGridView Name="RadGridView1" AutoGenerateColumns="False" >
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn Header="State" DataMemberBinding="{Binding Path=State}">
            <telerik:GridViewDataColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding State}" />
                </DataTemplate>
            </telerik:GridViewDataColumn.CellTemplate>
            <telerik:GridViewDataColumn.CellEditTemplate>
                <DataTemplate>
                    <telerik:RadComboBox x:Name="RadComboBox1" DisplayMemberPath = "State" SelectedIndex="1" SelectedValuePath = "Id" SelectedValue="{Binding Path=State}"/>
                </DataTemplate>
            </telerik:GridViewDataColumn.CellEditTemplate>
        </telerik:GridViewDataColumn>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

thanks
