The GridView fired event PageIndexChanging which wasn’t handled

Dear Friend

Here when you click your next page., server is post pack..
so dt (datatable or dataset) should be empty.,
that is the problem., so you try to keep dt value as viewstate like


when you getting data from database then you assign like.,

viewstate("dt_data")=dt;
GridView2.DataSource = dt;
GridView2.DataBind();

then now you add page index changing code like this..

protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
            {


                GridView2.PageIndex = e.NewPageIndex;
                GridView2.DataSource = viewstate("dt_data");
                GridView2.DataBind();
            }

that's all..

now you check page index is working fine.,


I hope this information is helpful to you.,

Thanks and regards

first you do

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
                               DataSourceID="SqlDataSource3" DataKeyNames="Id" AllowPaging="True" OnPageIndexChanging="GridView2_PageIndexChanging"
                               
  pageSize="10">

if you give

DataSourceID="SqlDataSource3"

then no need to DataSource =dt

just only write

protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
             {


                 GridView2.PageIndex = e.NewPageIndex;
                                 GridView2.DataBind();
             }

Please build it and used it if Probelm Persist than give your comment..
