validate the cell within a syncFusionGrid is ReadOnly?

Using JScript and TestComplete 9.31.3889

Application Under Test is a .NET thick client

I need to Log.Message the read only property of a cell.  I have tried Grid.Item(0,0).ReadOnly for a cell which will not accept input as well as a cell which accepts input, and both return False.  I have also tried (.Enabled, .AllowEnter) all return same results for cells that accept input as well as those which wont.  

Dev provided the following guidance but these properties are not available to me in TestComplete:

gridControl.ActivateCurrentCellBehavior = Syncfusion.Windows.Forms.Grid.GridCellActivateAction.None

The point of this test is to confirm customers arent able to change values in protected cells.
