Hi andrewpraveen,

Welcome to the MSDN forum.

This is a VB IDE forum. Your topic about datagrid issue is out of scope here. Pay attention that datagrid is a Web UI control. If this is an ASP.Net issue, please connect the ASP.net forums with this link: http://forums.asp.net/. If this is a VB.Net issue, I will move this thread to VB general forum and please show the code about your issue at the same time.

I look forward your reply.

I m concerning about grid view control in the visual studio IDE (vb.net).

Finally I manage it by enforcing the data constrains set to false. Now its perfectly working with my wish.
