Hi,
I'm sorry. The Application cannot be shared since it is restricted. Herewith I've attached entire snapshot of the Silverlight Part.
Using Ranorex SPY: There is a container "ContentFrame". Inside that container, one TabPageList control is available. 2 tab controls are displayed (radTabItem1 & RadTabitem2) inside of that TabPAgeControl. But there are 3 Controls actually (I used UIAVerify to identify that third control. (Please refer the screenshot :"RanorexSnapshot.png")

Using UIAVerify SPY:When I spy using UIAVerify tool, I'm able to see the third control ("grdShipment" data grid). (I've attached the screenshot [UIAVerify_MouseHover.png]. please refer). But I forced UIAVerify Tool to identify that control by Ctrl Clicking.

I tried to record the flow using Ranorex recorder. But Ranorex is not able to recognize that "grdShipment" DataGrid.
