  Hi.

  I am setting a DataTable a data source for a worksheet and now I want to show an icon or an vector graphic object in the row header, depending on the data contained in each row. I have modified the style for RowHeaderCellPresenter like this

  <Style TargetType="ss:RowHeaderCellPresenter">
              <Setter Property="Background" Value="Transparent"/>
              <Setter Property="HorizontalContentAlignment" Value="Stretch" />
              <Setter Property="VerticalContentAlignment" Value="Stretch" />
              <Setter Property="IsTabStop" Value="False" />
              <Setter Property="Template">
                  <Setter.Value>
                      <ControlTemplate TargetType="ss:RowHeaderCellPresenter">
                              <Border
                                  Width="16"
                                  Height="16"
                                  Margin="4,-2,0,0"
                                  VerticalAlignment="Center"
                                  controls:VectorGraphic.Foreground="CornflowerBlue"
                                  Child="{StaticResource VectorIconDelete}"
                                  ToolTip="test tooltip"
                                  ToolTipService.ShowDuration="6000000" >
                                  </Border>
                      </ControlTemplate>
                  </Setter.Value>
              </Setter>
          </Style>
  
  

  The result is like this
  
  

  Now, i have to place a trigger or something like that. But I have no clue how to get access to the data of each row, to set a different vector graphic depending on the rows data. Any ideas or other approaches?

  Best regards,

  Sascha

  Hi Sascha,

  You would need to get the icon object with VisualTreeHelper and capture it’s click event.

  Thanks,
