I have a XamGrid (2011.2) which when it is in edit mode, and a user navigates to a certain cell, I need to provide an assist.  I need to be able to automatically select the existing contents so that they can just start typing to erase the old content. 

What I need is something similar to this, except that I need to get access to the textblock contained in the cell.  The cell has no such property SelectAll.  This is the approach I would use if it was a straight TextBox.  Any ideas on this?

Private Sub dgDataEntry_CellEnteringEditMode(sender As Object, e As Infragistics.Controls.Grids.BeginEditingCellEventArgs) Handles dgDataEntry.CellEnteringEditMode
 
	Me._intDataEntryIndex = e.Cell.Row.Index
 
	Select e.Cell.Column.Key.ToLower()
 
	    Case "orgabbrvcd"
 
		Dim tb As Cell = sender
 
		tb.SelectAll()
 
           End Select
 
	End Sub
