You can to do following task to achieve this.

1) create a class level static DataTable

C#

static DataTable dtDataForGrid= new DataTable();

2)In the Page_Load method , fill DataTable dtDataForGrid and bind it with GridView.

C#

dtDataForGrid.Rows.Clear();

  //code to fill the DataTable dtDataForGrid

GridView1.DataSource = dtDataForGrid;
GridView1.DataBind();

3) After doing above job. generate the GridView1_PageIndexChanging event. and write the following code.

C#

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
   {
       GridView1.PageIndex = e.NewPageIndex;
       GridView1.DataSource = dtDataForGrid;
       GridView1.DataBind();

   }

hope this will help you out.

Thanks,
Arshad

Solution 1

So,

create event of pageindexchange of grid view and assign the new page index to grid view.

C#

protected void GridSummary_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        try
        {
            if (e.NewPageIndex != -1)
            {
                GridSummary.PageIndex = e.NewPageIndex;
                // Call the method to assing datasource to grid view again
            }
            else
            {
                
            }
        }
        catch
        {
        }

    }

please share your code.

after setting new page index you need to call the data bind method to grid view again...
