Using CellEditTemplateSelector with different sources for Combobox

[Maria]

In my scenario I have a column that can have a ComboBox or a TextBox and it's defined in the following way:

<telerik:GridViewDataColumn Header="Target" DataMemberBinding="{Binding Target}" Width="70" ValidatesOnDataErrors="None" CellEditTemplateSelector="{StaticResource TargetEditStyleSelector}"/>

My templateSelectors are defined here:

<UserControl.Resources>
        <templateSelectors:TargetCellEditTemplateSelector x:Key="TargetEditStyleSelector">
            <templateSelectors:TargetCellEditTemplateSelector.TextBoxTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding Path=Target, Mode=TwoWay}" HorizontalAlignment="Stretch" />
                </DataTemplate>
            </templateSelectors:TargetCellEditTemplateSelector.TextBoxTemplate>
            <templateSelectors:TargetCellEditTemplateSelector.ComboBoxTemplate>
                <DataTemplate>
                    <ComboBox DisplayMemberPath="Name" SelectedValue="Id" ItemsSource="{Binding Source={StaticResource comboBoxSource}}"/>
                </DataTemplate>
            </templateSelectors:TargetCellEditTemplateSelector.ComboBoxTemplate>
        </templateSelectors:TargetCellEditTemplateSelector>
    </UserControl.Resources>

The problem is that comboBoxSource can be changed in code depending on the value selected in another column and I'm not sure how to properly bind the source of that combobox. Any help is highly appreciated. Thanks!

Does anybody have an idea? Ple-e-e-ease? :)

Hello Maria,

You may use a converter that checks the value in the other column and conditionally passes the correct source for the ComboBox.

DO you happen to have an example of this scenario?

Thanks again!

Hello Maria,

On a side note, there is another approach to similar scenarios, for which we have an example. Please, refer to this blog and inform us if this solution meets your requirements.
