GridViewComboBoxColumn doesn't work properly on edit

[Ramsha]

The ItemsSource of GridView:

ProductID,

Name,

Code,

ProductTypeName(GridViewComboBoxColumn)

The ItemsSource for GridViewComboBoxColumn :
ProductTypeID,

ProductTypeName

The problem is when I select another item from the ComboBox after double clicking the column in the RowEnded event, it doesn't give me the Updated ProductTypeID, instead it always gives me the ProductTypeID which was first bound when I loaded the GridView. I think there is some issue with the Bindings

Here is the Xaml:

<telerik:RadGridView.Columns>
   <telerik:GridViewDataColumn x:Name="ID" 
        DataMemberBinding="{Binding ProductID}" 
Header="ID" 
IsReadOnly="True" 
        IsVisible="False"/>

    <telerik:GridViewDataColumn x:Name="Code" 
        DataMemberBinding="{Binding Code}" 
        Header="Code" 
        IsReadOnly="False" />

    <telerik:GridViewDataColumn x:Name="Name" 
        DataMemberBinding="{Binding Name}" 
        Header="Name" 
        IsReadOnly="False" />
                   
<telerik:GridViewComboBoxColumn DataMemberBinding="{Binding ProductTypeName}"
        UniqueName="ProductType"
        SelectedValueMemberPath="ProductTypeName"
        DisplayMemberPath="ProductTypeName"
        Header="ProductType"/>

    </telerik:RadGridView.Columns>
</telerik:RadGridView>

Hello Ramsha,

I believe you would find the following article regarding the ComboBox Column helpful. I would also recommend having a look at our developer-focused examples in our SDK Examples Browser and more specifically - the ones regarding the ComboBoxColumn. Please also have a look at the following demo about the RadGridView ComboBoxColumn.

To help you out, I've attached a sample project, resembling the scenario you've described. Please have a look at it and let me know whether it works for you.
