Hi.  We are using a XamGrid with a TemplateColumnLayout.  Upon clicking the expander, we would like to populate the datatemplate with a user control from the code behind so we can swap out user controls dynamically.

I am currently subscribing to the "OnRowExpansionChanging" event, but can't seem to populate the cells with any content:

private void ResultsXamGrid_OnRowExpansionChanging(object sender, CancellableRowExpansionChangedEventArgs e)
{
     e.Row.Cells[6].Content = new AddEditPlanting();
}

I would also like to get at the "Key" for the TemplateColumnLayout so I can pass that into the constructor of my usercontrol.

Thanks for your help.
