DataTable Export Execl
The code is too simple, we look at the code directly.

Copy Code code as follows:

    protected void Btnprint_click (object sender, EventArgs E
    {
        string strpath = "Mfout" + DateTime.Now.ToStr ING ("yyyymmddhhmmssfff") + ". xls";
        DataGrid dg = new DataGrid ();
        DG. DataSource = Dtmain;
        DG. DataBind ();
        response.clear ();
        Response.AddHeader ("Content-disposition", "attachment;filename=" + strpath + "");
        Response.Charset = "gb2312";
        response.contentencoding = system.text.encoding.utf8;//is not set to be garbled
        Response.ContentType = "Application/vnd.xls";
        System.IO.StringWriter stringwrite = new System.IO.StringWriter ();
        System.Web.UI.HtmlTextWriter htmlwrite = new HtmlTextWriter ( Stringwrite);
        DG. RenderControl (Htmlwrite);
        Response.Write (stringwrite.tostring ());
        Response.End ();
   }
    public override void Verifyrenderinginserverform
    {
       /This method can not delete the export to use, or it will error:
         Control ' ctl00_contentplaceholder1_gridview1 ' of type ' GridView ' must be placed inside a form tag with Runat=server
   }
