GridView Paging and Sorting with url parameters in asp.net c#

Many times we want to want to add actual page number to the url. This code will help you .

Code behind:-

We need to call this method on page index

  protected void Gridview1_PageIndexChanging(object sender, GridViewPageEventArgs e)

    {

       

        e.Cancel = true;

        int index = e.NewPageIndex + 1;

        string urlPath = HttpContext.Current.Request.Url.AbsoluteUri;

        Uri uri = new Uri(urlPath);

        string url = uri.GetLeftPart(UriPartial.Path);

        Response.Redirect(string.Format("{0}?page={1}", url, index));

    }

We can call this method on page load

   protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            if (Request.QueryString["page"] != null)

            {

                int index = int.Parse(Request.QueryString["page"]);

                Gridview1.PageIndex = index-1;

                Gridview1.DataBind();

                bindgirdview();

            }

            else

            {

                bindgirdview();

            }

        }

    }
