Try this,

XML

<asp:TemplateField HeaderText="S.No.">
<ItemTemplate>
<asp:Label ID="lblSNo" runat="server" Text="<%# (Container.DataItemIndex)+1 %>"> 
</asp:Label> 
</ItemTemplate>
</asp:TemplateField>

if the page has 5 items it is generating numbers from 1 to 5, but what i needed is, if i select the some more items for form.2 to should generate the number continuing from 5.

k,then pass that required no as a field and modify the code to add that field in place of 1(As it is now).

Try this,
<asp:Label ID="lblSNo" runat="server"
Text='<%# (Container.DataItemIndex+1)+Convert.ToInt16(Eval("fld")) %>'>

Where fld is the field in which pass no. of rows.
