Hi guys,

I am trying to display an image in a cell (UnboundField) of a XamDataGrid based on a value of another cell.

With a DataGrid I got it working like this:

<DataGrid Name="dataGrid" ItemsSource="{Binding}" >
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Text" Width="SizeToCells" IsReadOnly="True">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Image Source="{Binding Path=id, Converter={StaticResource IdToImageConverter}, ConverterParameter='png'}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Could anyone help me with that in a XamDatagrid? This is my code which is not working, I guess the problem is the wrong RelativeSource in the ControlTemplate:

<UserControl.Resources>
    <local:IdToImageConverter x:Key="IdToImageConverter" />
    <Style x:Key="IconCellStyle" TargetType="{x:Type igDP:CellValuePresenter}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
                    <Grid>
                        <Image Source="{Binding Path=id, Converter={StaticResource IdToImageConverter}, ConverterParameter=png, RelativeSource={RelativeSource AncestorType={x:Type igDP:XamDataGrid}}}" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</UserControl.Resources>

<igDP:XamDataGrid Name="xamDataGrid" DataSource="{Binding}" >
    <igDP:XamDataGrid.FieldLayouts>
        <igDP:FieldLayout>
            <igDP:FieldLayout.Fields>
                <igDP:UnboundField Label="Text">
                    <igDP:UnboundField.Settings>
                        <igDP:FieldSettings CellValuePresenterStyle="{StaticResource IconCellStyle}" />
                    </igDP:UnboundField.Settings>
                </igDP:UnboundField>
            </igDP:FieldLayout.Fields>
        </igDP:FieldLayout>
    </igDP:XamDataGrid.FieldLayouts>
</igDP:XamDataGrid>

Thanks a lot and kindregards!
