As part of work I’m doing at the moment, building a UI automation API for our testers. I continually come across issues around data grid controls and access the rows within it (we’re primarily using XamDataGrids from Infragistics).

What I need is to have an AutomationId reflecting some form of index in the grid. Good news is we can do this…

If we take a XamaDataGrid and create a style such as this

<Style x:Key="RowPresenterStyle" TargetType="igDP:DataRecordPresenter">
  <Setter Property="AutomationProperties.AutomationId" Value="{Binding DataItemIndex}" />
</Style>

and now in the XamDataGrid’s FieldLayoutSettings we can apply this style using

<igDP:XamaDataGrid.FieldLayoutSettings>
  <igDP:FieldLayoutSettings
     <!-- Other settings -->
     DataRecordPresenterStyle="{StaticResource RowPresenterStyle}" />
</igDP:XamaDataGrid.FieldLayoutSettings>
