Build Binding Paths in WPF Data Grid Rows

Row elements contain RowData objects in their DataContext. Use the following binding paths to access cell values and ViewModel properties:

• Row.[YourPropertyName] - access a property of an object in the ItemsSource collection (see RowData.Row);
• DataContext.[FieldName] - access a column value in Server Mode, access an unbound column value (see RowData.DataContext);
• View.DataContext.[YourPropertyName] - access a property in the grid's ViewModel (see RowDataBase.View).

The bindings used in this example work as follows:

• Bind the row Background to the Color property stored at the item level:

<Trigger Property="SelectionState" Value="None">
    <Setter Property="Background" Value="{Binding Row.Color, Converter={dxmvvm:ColorToBrushConverter}}" />
</Trigger>

• Highlight a row when the HighlightVisited property of the grid's ViewModel and the Visited column value are true:

<MultiDataTrigger>
    <MultiDataTrigger.Conditions>
        <Condition Binding="{Binding View.DataContext.HighlightVisited}" Value="True" />
        <Condition Binding="{Binding DataContext.Visited}" Value="True" />
    </MultiDataTrigger.Conditions>
    <Setter Property="TextElement.FontStyle" Value="Italic" />
    <Setter Property="TextElement.FontWeight" Value="Bold" />
</MultiDataTrigger>
