I didnt use bound field here.
as it is simple grid view with auto generate columns. I want to make some columns Editable while some should not be editable
<asp:GridView ID="noticeDetails" runat="server" AutoGenerateEditButton="True"
onrowediting="noticeDetails_RowEditing1"
onrowupdated="noticeDetails_RowUpdated1"
onrowupdating="noticeDetails_RowUpdating1"
BorderWidth="1px" Width="100%" CellPadding="10">
</asp:GridView>
