        }
        catch (Exception ex)
        {

        }

    }

C#

void MaterialCart1_PostItems(EIPCommonControls_EIPCart.CartTypes CartType, DataSet ds)
   {

       if (CartType == EIPCommonControls_EIPCart.CartTypes.Material)
       {
           GetMaterialList();
       }
       if (CartType == EIPCommonControls_EIPCart.CartTypes.Job)
       {
           GetJobList();
       }
   }

And here in page load

C#

           //

           if (!IsPostBack)
           {

               // Date = DateTime.Now.Year;
               pnlAdd_ModalPopupExtender.Hide();
            //   lblCurrentDate.Text = DateTime.Now.ToString("dd-MMM-yyyy");
               //((EIPMasterTemplate)(Master)).UID = Convert.ToInt32(Session["iUid"]);

               EIPFilterWarehouse.Parameters = "intUID:" + Session["iUid"] + ",intDTCode:" + Session["iDTCode"] + ",chrDOPTCode:" + 'V' + ",chrAccessTag:" + 'Y';
               EIPClassList.Parameters = "intCompanyCode:" + Session["iCompanyCode"] + ",intUID:" + Session["iUid"];

               month = DateTime.Now.Month;


               ddlToDate.EndYear = Date + 1;
               ddlToDate.SelectedYear = Date.ToString();
               (ddlToDate.FindControl("ddlToDateMonths") as DropDownList).SelectedValue = (month-1).ToString();

               ddlFromDate.EndYear = Date + 1;
               ddlFromDate.SelectedYear = Date.ToString();
               (ddlFromDate.FindControl("ddlFromDateMonths") as DropDownList).SelectedValue = (month - 4).ToString();

       catch (Exception ex)
       {
           MsgBox.ShowError("EIP Error", ex.Message);

Not sure of the business logic. Might be due to the fact that you are binding different tables on page index changing. You should bind the exactly same table, which you have bound initially. But you have many conditions inside the bind method.

Hi,

A couple of points:
PageSize - where do you define this? I can't see it in your posted code.
PageIndex - you have defined this as an attribute in the GridView markup:

ASP.NET

<asp:GridView id="grvMatGrp" ... PageIndex="10" ... ></asp:GridView>

I would remove this from the mark up, and leave it to the code you have in PageIndexChanging() to take care of it for you.

I would also recommend that have a read at this article:
How To Implement Paging in GridView Control in ASP.NET[^]
... as this provides a better explanation of the available paging functionality than I can in this solution.

... hope it helps.
