How to check whether the properties is "(Null Object)"?

Hi all,



I am testing a SilverLight application which use ComponentOne Grid. When I use the object browser to spy the object, it shows that there is a object with FullClassName C1.Silverlight.DataGrid.DataGridCellPresenter.



My task is what to check the "Cell" properties is "(Null Object)" or not. I have tried isNull or isEmpty function in VBscript, but it does not work.



Anybody can help me?



Thanks in advance.



Regards,

Null
