3) Describe problem:
Im using Ajax Tab script in my ASP.Net application. i have GridView in each tab. In the GridView i have added the bound fields and also in the Grid's RowCommand Event i have assigned grid's row values to the text boxes.

This thing is working perfectly with/without Master pages. now when i include the tabs then the default page is working fine with this and also the external page is called successfully with data loaded in the grid.

But when i click the data for a call to RowCommand Event then it shows the Invalid State Exception. The trace is given below.
