I have Question for you.

Iam confused with Export to excel in gridview. my all grid view design
structures are in client side. so using javascript I got a downloaded File
format as the result of export to excel without .xls extension. When i
trying to write code in controller, i got a .xls file with empty data.
since i don't know how to get clint side webgrid value to the server side
controller, so thet i just reuse the method again for getting grid data in
server side where i tryed to return
file(stream,"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet").
But did't get a best result. I kindly expect your help.

Thanks and Regards

Hi i know two waies to export to xls
first : loop to DataTable and create manauly then write it to response.

C#

<pre lang="cs">Response.ContentType = "application/vnd.ms-excel";
          Response.AddHeader("content-disposition", "attachment;filename=MyFiles.xls");

second : use exporters link Devexpress ASPXGridExporter.

<pre lang="c#">

C#

protected void imbPersonsXLS_Click(object sender, ImageClickEventArgs e)
       {
           GridExporterPersons.WriteXlsToResponse();
       }

the second way is very easy and devexpress aspxgridview filter also suported.

... I can wrot my code here..

//controller
public ActionResult GetRMAList(string gridData, string RMADateFrom, string RMADateTo, string PM20SN, string PhSNo, string sort = _rmaDefaultSortCol, string sortdir = defaultSortDir, int? page = 1)
{
var stream = new MemoryStream();
//var sb = new StringBuilder();
//sb.Append(gridData);
try
{.....
.........
IEnumerable<DtoRMAMonitor> pagedrmamonitors = Enumerable.Empty<DtoRMAMonitor>();

PagedResult<DtoRMAMonitor> rmaMonitors = new PagedResult<DtoRMAMonitor>();

rmaMonitors = _RMAManager.GetRMAMonitors(null, null, serialNumber, phoneSNo, null, RMAdateFrom, RMAdateTo, null, sort, sortdir, pageSize, page.Value);

currentPageIndex = page.HasValue ? page.Value - 1 : 0;
totalrows = rmaMonitors.RowCount;
pagedrmamonitors = rmaMonitors.Results.ToPagedList(currentPageIndex, pageSize, totalrows);

this.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

XmlDocument xmlDoc = new XmlDocument();

Hi. the link that Abhinav S was very easey and clear here the thing which you need is very simple and easy...

C#

<pre lang="cs">protected void Button1_Click(object sender, EventArgs e)
{
    HttpContext.Current.Response.Clear();
    HttpContext.Current.Response.AddHeader("content-disposition",
        string.Format("attachment;filename={0}.xls", "Exported"));
    HttpContext.Current.Response.Charset = "";
    HttpContext.Current.Response.ContentType = "application/ms-excel";

    using (StringWriter sw = new StringWriter())
    {
        using (HtmlTextWriter htw = new HtmlTextWriter(sw))
        {
            //  Create a table to contain the grid
            Table table = new Table();

            foreach (GridViewRow row in GridView1.Rows)
            {
                table.Rows.Add(row);
            }

            //  render the table into the htmlwriter
            table.RenderControl(htw);

            //  render the htmlwriter into the response
            HttpContext.Current.Response.Write(sw.ToString());
            HttpContext.Current.Response.End();
        }
    }
}

Use this Simple Functionality and Avoid doing Complex Coding the beauty is in Simplicity.
