Hi Gregg,

Just setting Tag="{Binding}" should do the trick.

Hope that helps,

Hi Steve

One last question (I hope).  How do I bind the GroupByDataContext to the tag?  Can't quite seem to get the syntax right.

Thanks, Gregg

Hi Steve

Thanks again for your help.  I believe I have found the error of my ways and was able to use the data template to handle the event.

Thanks again, Gregg

Hi Gregg, 

There currently isn't an event that fires when a control is attached to GroupByCell.

Out of curiosity, why do you need to add the eventhandler in code, as opposed through the data template?

Hi Steve

Again, thanks for the reply.  I have a need to add in the event handler through code as opposed to XAML and I can't seem to figure it out.  Here is the significant part of the XAML:

                        <igDataGrid:XamWebGrid x:Name="EventsGrid"   Foreground="DarkBlue"  FontSize="10" Background="WhiteSmoke"  VerticalAlignment="Top" HorizontalAlignment="Left" Opacity="0.85" >

                           <igDataGrid:XamWebGrid.Columns>

                                <igDataGrid:TextColumn Key="event_id" HeaderText="Event ID"/>
                                
                                <igDataGrid:TextColumn Key="Event_Type" HeaderText="Category" x:Name="EventColumn">
                                    <igDataGrid:TextColumn.GroupByItemTemplate >
                                         <DataTemplate x:Name="MyGroupTemplate">
                                            <StackPanel Orientation="Horizontal">
                                                <CheckBox x:Name="GroupCheck" IsChecked="True" />
                                                <TextBlock Text="{Binding Value}"></TextBlock>
                                                <TextBlock Text=" (" />
                                                <TextBlock Text="{Binding Count}"></TextBlock>
                                                <TextBlock Text=")" />
                                            </StackPanel>
                                        </DataTemplate>
                                    </igDataGrid:TextColumn.GroupByItemTemplate>
                                </igDataGrid:TextColumn>

                            </igDataGrid:XamWebGrid.Columns>

                        </igDataGrid:XamWebGrid>

I need an addhandler statement like this one but I can't quite figure out how to reference the checkbox in the GroupByItemTemplate.

 AddHandler DataWindow.EventsGrid.SelectedRowsCollectionChanged, AddressOf EventSelected

I appreciate the help.  Gregg
