Girdview Pagination Disappears

[arunmagnilagan]

i had used gridview to display records from database, i am able to display records but in pagination when i click 2,3,4,5......10 page the gridview disappears.

find the code below for gridview:

<asp:GridView ID="GridView1"   runat="server"  AllowPaging="True" PageSize="10"   AutoGenerateColumns="False" OnPageIndexChanging="GridView1_PageIndexChanging" onselectedindexchanged="GridView1_SelectedIndexChanged"
        GridLines="Horizontal">

code behind:

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.BottomPagerRow.Visible = true;
       
        GridView1.PageIndex = e.NewPageIndex;
      
        GridView1.DataBind();
        
        
    }
