Hello Sundance,

In order to select XamGrid Rows on right-click, I would recommend that you write a Style for CellControl and use an EventSetter to hook into the PreviewMouseRightButtonDown event. This Style could look like the following:

<Style TargetType="{x:Type ig:CellControl}">
  <EventSetter Event="PreviewMouseRightButtonDown" Handler="CC_PreviewMouseRightButtonDown"/>
</Style>

The CellControl element is essentially the "presenter" for a particular cell, and you can obtain the Cell element that it is presenting by casting the above-mentioned EventHandler's sender to a CellControl and utilizing its Cell property. From the Cell, you can get the Row from the Cell's Row property and mark it's IsSelected property accordingly.

I have attached a sample project to demonstrate the above. I hope this helps you.

Please let me know if you have any other questions or concerns on this matter.

Sincerely,
Andrew
