Deleting AutoIncrement field in a Grid

Hi All, We have autoincrement field in our grid which is populated from the table itself. now the problem while deleting the record it thows an error saying invalid cast from system.Int32 to system.GUID. any help in resolving matter is appreciated. Thanking all, Purnaram.k

I tried to see this problem in this sample using version 3.0.1.0. I can click a row header and delete the row without a problem. Can you? http://www.syncfusion.com/Support/user/uploads/GDBG_AutoInc_1379a2bb.zip What is the DataType of the increment DataColumn? Is it int? If you set the debugger to break on exception, can you post the call stack here? Can you modify the sample to show the problem you are having?
