Hi Jenny,

See the below which is the CellEditor I used before for the ComboBox which is not working.

<xceed:CellEditor x:Key="SourceFieldEditStyle">
            <xceed:CellEditor.EditTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" AllowDrop="True">
                        <ComboBox ItemsSource="{Binding dataMapFields}" DisplayMemberPath="field_name" SelectedValuePath="field_name" HorizontalAlignment="Stretch"/>
                </StackPanel>
                </DataTemplate>
            </xceed:CellEditor.EditTemplate>
        </xceed:CellEditor>

This CellEditor is used for the Column with FieldName "field_name". Here "dataMapFields" is the DataTable in the codebehind. I hope this details would help to debug my problem.

 
If possible give me a sample code that will load DataTable to a ComboBox in a DataGridControl. The filling up of the DataTable should be dynamic and code should not be in App Context.

Thanks
