title: XamDataGrid show an empty row when Collection is empty
body: <p>![enter image description here][1]I have a XamDataGrid that binds to a Collection. The code runs fine and XamDataGrid is showing the Data when collection is having data.</p>
  
  <p>But, if I Clear() the collection and assign to the datasource, the XamDataGrid is also clear but left with one single empty row, which I don't know how to get rid of. I have cleared the collection. Where the empty row come from?</p>
  
  <p>Using Infragistics 10.2</p>
