CellValuePresenter control template that acceses other values of bound data item
posted
I would like to make a cell value presenter control template that displays an icon depending on one value of the bound data item and some text from another property of the bound data item. I know to bind to the content of the field associated with the cellvaluepresenter I can use...

<TextBlock Width="Auto" Height="Auto" Text="{TemplateBinding Content}" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="5,0,0,0" VerticalAlignment="Center" Foreground="#FF000000" x:Name="textBlock"/>

How can I bind to another field/property for the data item? Should I bind to something on the TemplatedParent or is this just impossible?

Thanks! I've provided my full control template below....

 

<Style x:Key="UnitTypeFieldCellImages" TargetType="{x:Type igDP:CellValuePresenter}">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">

<StackPanel x:Name="stackPanel" Orientation="Horizontal">

<Grid Margin="5,0,0,0" x:Name="grid" Width="32" Height="32">

<Grid Width="32" Height="32" x:Name="policecarimage" Visibility="Visible" HorizontalAlignment="Left" VerticalAlignment="Top">

<!--<Image Source="images/policecar_32.png" Height="32" Width="32" />-->

<Image Source="{StaticResource CopCarIcon}" Height="32" Width="32" />

</Grid>

<Image x:Name="firetruckimage" Source="{StaticResource FireTruckIcon}" Height="32" Width="32" Visibility="Hidden" />

</Grid>

<TextBlock Width="Auto" Height="Auto" Text="{TemplateBinding Content}" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="5,0,0,0" VerticalAlignment="Center" Foreground="#FF000000" x:Name="textBlock"/>

</StackPanel>

<ControlTemplate.Triggers>

<Trigger Property="Content" Value="FD">

<Setter Property="Visibility" TargetName="policecarimage" Value="Hidden"/>

<Setter Property="Visibility" TargetName="firetruckimage" Value="Visible"/>

</Trigger>

</ControlTemplate.Triggers>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

    Hi -
     
    Since the DataContext of the CellValuePresenter is set to the DataRecord, you can use a standard binding where the Path parameter is set to the name of the Field/Property you want to bind to off the DataItem property of the DataRecord. (the DataItem property returns the underlying data for the DataRecord)
     
    {Binding Path=DataItem.MyFieldName}
