Have you considered using the ReportViewer control with an embedded report? It will handle the Excel export in native Excel.

Hi sailajaranit,

Maybe you code has something wrong,please try to the following code.

Response.AddHeader("content-disposition", "attachment;filename= Report.xls");
Response.ContentType = "application/";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

Let me know if I have misunderstood what you mean.
Hope it helps,
Hua Jun

Try this code.  This code will export data in a repeater control, but you could substitute it for a gridview control if you like.  Remember if you have paging enabled, it won't export all the records in the gridview.  It will only export the data that is in the gridview on that page.

string fileName = string.Format("attachment;filename={0}.xls", DateTime.Now.ToString("yyyyMMddHHms"));
Response.AddHeader("content-disposition", fileName);
Response.Charset = string.Empty;

Response.ContentType = "application/vnd.xls";
using (System.IO.StringWriter stringWrite = new System.IO.StringWriter())
    using (System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite))

If you need to export large data to excel, you might consider using BCP:

That is a great tool which will efficiently export large data to an external file.

Hope this helps.

Implementing .Net Form into an web form, can this be done
I am new here, but have been searching for a while, and may not have the correct lingo to find what I am looking for.  I am tasked with implementing a .exe application that was writen vb6 then converted to .net into a new website my team is developing.

Reading Excel Files from a .Net Web Form
Hi, This might be a dumb question, but ... When reading an Excel file from a .Net Web Form, is it necessary to have Microsoft Excel actually installed on the client machine running the web form? Also, do the Excel files being read need to be saved as "values only" or can the values be extracted from a spreadsheet where the cells contain formulas? Thanks. -Wayne Hi, For the 1st part, Office is not necessary to be installed. But Download the Office XP PIAs and use them to develop Office XP solutions with Visual Studio .NET.

How to Make Web Forms from other Web Forms
In putting together an ASP.NET application for a biz application, we have come to the point where there are three different types of basic forms which have, for the most part, been perfected. Now its is a matter of cloning those forms for various uses and modifying or adding code to suit the particular need. Copy and paste works OK, but there is a lot of changing of certain words, etc. Is there a way in ASP.NET to take these basic forms, turn them into classes or templates, create forms from them, then add or overwrite code? ?

Importing Individual Web Forms and User Controls from a Web Site
Is there a best practice for importing individual web forms and user  controls from a web site to a web application project (i.e., to ensure the .designer file is generated and all that)? On the new version of an existing web site, we're moving the WAP, but we're changing the project enough that I don't want to just upgrade the whole thing--I just want to import select forms and controls. So far, the best thought I've got is to do a fake upgrade and copy over files from that, but that's a bit heavy for my needs, so if there's an easier or better way to just grab the ones I want, pleas...
