I've been working on this for a while and everything that I have read seems to tell me to use the same setup. I have been able to export the data to an xls file on my local C drive but that won't work when hosted on the server as I'll want users to export their data to their local machines as well... I guess the issue I'm having (or at least what I think am having) has to do with my response.end() function. I'll give you my code that works and the one that doesn't... In the end they will both do the same thing...Here is the code I've been playing with for my button:

Now here is where it will at least save on my local drive via a button in my drop down menu:

I am trying to write a bit of code that will export the current contents of a gridview to an excel file on the local system. I've looked at several examples on how to do it and implemented it. However, i am unable to get the gridview to export the data.
Here's the basics of what i am doing:
I'm using httpcontext.current.response to specify the file contents and filename. creating Stringwriter and htmltextwriter objects.
then rendering the table into the htmlwriter then rendering the htmlwriter to the response.
however, regardless of how large or small the table i am working with is, i keep getting the following error:

I get following error when exporting to Excel.
"The file you are trying to open, 'someFileName[1].xls, is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"
Clicking Yes opens the file. I would like to avoid showing the above error to the users.

I've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.
View 1 RepliesI'm exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text"
Table.CaptionAlign = TableCaptionAlign.Top
but i get error Reference to a non shared member requires an object reference.
when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data. I have read many articles but in the end i have downloaded the code from URL...and i adapted for my code. The problem is that when i press the ExporttoExcel button it's exporting only this...I cannot figure out that is the problem.
