I have designed one web page in asp.net. In that i have used the css file and excel generation button. While i am cliking the button for populating the data from database to excel. It is showing the problem in uploading the css file like that .What will i do the for removing the that error.
For opening the excel sheet I have used the following code that is
Response.ContentType = "application/xls";
Response.AddHeader("Content-Disposition", "attachment; filename=itext.xls");
Is there anything wrong in this?
