CellTemplate as ComboBox Changes Value in All Rows

[Robert Kaucher]

I have aRadGridView controm populated by a DOmainDataSource. It populates teh GridView with information about part objects.

 I have another DomainDataSource that is configured as a static resource in XAML and is used to populate a combobox with ForecastOwner objects. These are associated objects of the Part objects.

Part * => 1 ForecastOwner

I have the column celltemplate defined as this:

<telerik:GridViewDataColumn.CellTemplate>
    <DataTemplate>
        <ComboBox
            ItemsSource="{Binding Data, Source={StaticResource forecastOwnerDomainDataSource}, Mode=TwoWay}"
            SelectedValue="{Binding ForecastOwnerID, Mode=TwoWay}"
            SelectedValuePath="ForecastOwnerID"
            DisplayMemberPath="FullName" />
    </DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>

The issue I am having is that when I define it as a CellTemplate when I make a selection change it changes the field in every row of the GridView, not just the selected row.

When I define it as CellEditTemplate nothing, no text at all, is displayed until I click in the cell. If I define both a CellTemplate and a CellEditTemplate (say CellTemplate as a TextBox) it over rides the CellEditTemplate. No big deal, I define the CellTemplate as a TextBlock and it works UNTIL I change the selection and then, of course, I have nothing displayed in that cell because the TextBlock is bound to the Part's associated ForecastOwner's FullName Property. So I assume I need some sort of value converter, but I am a little stumped. Thank you in advance for your help.

Hi Robert,

May you try to use RadComboBox instead of ComboBox? Furthermore, you may benefit from the GridViewComboBoxColumn.
