Solution 2

What and why are you doing this: GridViewRow rows = gvd.Rows[index1];"

Pagination is not implemented like this. All you need to do is increase the page count and rebind the grid. .NET will automatically show the correct rows.
Refer: MSDN: GridView.PageIndexChanged Event[^]

page size is six and index value is 11 so rows[11] is exceeding any array size

Thats what I said. You cannot force page to move on if there are no as many records.

Hi,
try this:

Add the following in your html code:

VB

<asp:GridView ID="gvd" runat="server" AllowPaging="True"
        onpageindexchanging="gvd_PageIndexChanging"

and the following code in codebehind:

C#

protected void gvd_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        gvd.PageIndex = e.NewPageIndex;
        gvd.DataBind();
    }

Thank you
