Coding for PageIndexChanging

C#

Solution 1

This is completely a guess.

I guess you have written code for loading the GridView on the Page_Load too. If yes, make sure you check for IsPostback property and load the GridView.

Like,

C#

private void Page_Load (object sender, EventArgs e)
{
    if (!IsPostback)
    {
        //load your GridView here
    }
}

Mark it as answer if it is helpful.

Following MSDN articles should give you complete overview of how datagrid's pagination work and the related code:
MSDN DataGrid.PageIndexChanged Event[^]
MSDN: Creating a Pageable, Sortable DataGrid[^]

Solution 3

When any event called on web page the PageLoad get calls prior that.
It may happens that you have not put IsPostBack in your PageLoad

give session["dt"]=dt as datasource but update
int pageno=convert.toint16(viewstate["pageno"])+your page size;

viewstate["pageno"]=pageno;

Solution 5

In your SelectedIndexChanging event , you write the following code

MIDL

GridBank.PageIndex = e.NewSelectedIndex;
GridBank.DataSource = (DataTable)ViewState["Bank"];
GridBank.DataBind();
