How to use RadGridView-GridViewDataColumn.BindingGroup

[Aihua]

hi:
 I have a question when use GridViewDataColumn.BindingGroup,my core code as follow:

<telerik:GridViewDataColumn Header="Time" IsReadOnly="True" SortMemberPath="ScheduledProcedureStepStartDateTime">                        
                        <telerik:GridViewDataColumn.BindingGroup>
                            <MultiBinding Converter="{StaticResource timeRangeConverter}" ConverterParameter="HH:mm">
                                <Binding Path="StartDateTime"></Binding>
                                <Binding Path="EndDateTime"></Binding>
                            </MultiBinding>
                      </telerik:GridViewDataColumn.BindingGroup>
</telerik:GridViewDataColumn>

Please confirm syntax of binding is right?

When execute 
 public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture){} function,
I found values[0] and values[1] are DependencyProperty.UnsetValue. So can't convert successfully.

Please provide the right telerik demo. Tahnks.

Hi,

In RadGridView columns do not participate in the visual tree as separate visuals  . They just define common properties for cells. Using the BindingGoup  property on a column would have no effect on the behavior of RadGridview.
