Dear Friends,

I am exporting my data to excel by rendering html to excel format. But when exporting large data, then the data doesn't get exported instead an exception occurs like:- "system.outofmemoryexception ".

The excel file size is 23.1 MB for around 7000+ records. In some PC it is working fine but at client side it is giving the above mentioned error.

My code is:-

Dim attachment As String = "attachment; filename=OutstandingReport.xls"
Response.ClearContent()
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/ms-excel"
ReportTable.RenderControl(htw)
Response.Write(sw.ToString())
Response.Flush() 'Added By: Varun Sareen on 17th June, 2013
Response.[End]()

Here the ReportTable is the HTMl code with data.

Please help me in this regard if any one is having a proper solution.

Thanks & Regards

If you configure your website properly, your clients will not see the details of server side errors like this. As the export is happening on the server side, this has nothing to do with memory on the client side, it may have to do with the server sometimes having enough RAM and sometimes not.

Buy more RAM.

This kind of problem happended when you have your application continuously running in visual studio... due to which memory got increasingly fill and this exception got thrown.. so If you are providing services to client.. deploy application over IIS or some server via physical path.. and dont let the Visual Studio run continuously....

This is what I Experienced.. so sharing it... hope will help.
