Hi All,

I'm trying to add a tooltip to my GridViewDataColumn's Header, but the tooltip never appears and I get no binding error. Can you tell me if this is the proper approach?

Cheers,
Scott

Code below:

                <telerik:GridViewDataColumn DataMemberBinding="{Binding SnmPerformance}" UniqueName="SnmPerformance"
                                            DataFormatString="n1" TextAlignment="Right" HeaderTextAlignment="Right"
                                            Width="80" IsFilterable="False" IsSortable="True" >

                    <telerik:GridViewDataColumn.Header>
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="*"/>
                                <ColumnDefinition Width="Auto"/>
                            </Grid.ColumnDefinitions>
                            <TextBlock Grid.Column="0" Text="SNM Performance" TextWrapping="Wrap"  ToolTipService.ToolTip="{Binding DataLastUpdatedText, Mode=OneWay}"  />
                            <telerik:RadButton Grid.Column="1" Click="btnSnmPerformanceColumnExpandClickHandler" Style="{StaticResource ColumnHeaderExpanderButtonStyle}" />
                        </Grid>
                    </telerik:GridViewDataColumn.Header>
                </telerik:GridViewDataColumn>

Hello Scott,

Indeed, this is the correct approach. You can check the Add ToolTip for columns and headers help article for a reference. Please ensure that there are no BindingExpression errors in your application.
