Programmatic Grouping by Column bound to data with converter

[Jason]

I am having trouble setting up grouping by a column that is bound to a data element that goes through a value converter.  Below I am trying to group by the Reading Station Column.

<tk:RadGridView Name="RoutesGrid"
            AutoGenerateColumns="False" IsSynchronizedWithCurrentItem="True"
            ItemsSource="{Binding PagedSource, ElementName=DataPager}" SelectedItem="{Binding SelectedRoute}"
                        tk:StyleManager.Theme="Summer" MouseRightButtonDown="RadGridView_MouseRightButtonDown">
            <!--<tk:RadGridView.GroupDescriptors>
                <tk:ColumnGroupDescriptor Column="{Binding Columns[\Reading Station\], ElementName=RoutesGrid}" />
            </tk:RadGridView.GroupDescriptors>-->
            <tk:RadGridView.Columns>
                <tk:GridViewDataColumn
					Header="ID"
					DataMemberBinding="{Binding ID}"
					TextAlignment="Center">
                </tk:GridViewDataColumn>
                <tk:GridViewDataColumn 
					Header="Reading Station"
					DataMemberBinding="{Binding ReadingWorkstation, Converter={StaticResource WorkstationToNameConverter}}"
					TextAlignment="Center" Width="Auto">

Hi Jason,

Actually, you are using the value set for the Header property in the ColumnGroupDescriptor definition and this is causing the problem. What you can do is either set the UniqueName property, or to directly use the name of the property - in your case  ReadingWorkStation.

I hope this helps.
