I read Luchian's suggestion on this link
Download Excel file via AJAX MVC
and I do like his idea very much that way I can avoid potentially saving 2 copies of the spreadsheet. Or having to worry about deleting the initial file that gets saved on the server before the AJAX call returns.
So if I save the spreadsheet as a memorystream and insert it into a unique Cache variable say cache_uniq1 and return that on the AJAX call, how would I then open the stream?
Can I just do window.open?
$.ajax({
type: 'POST',
url: '/Reports/Somepage.aspx',
data: '{ "dataprop1": "test", "dataprop2" : "test2" }',
//contentType: 'application/json; charset=utf-8',
//dataType: 'json',
success: function (returnValue) {
//window.location = /Reports/Download?file=' + returnValue;
//
//NOTE: Instead the returnValue = cache_uniq1 which is the unique Cache
//variable name that holds the Excel spreadsheet as a memory stream
}
});
Any help is greatly appreciated. FYI my application is a straight on ASP.Net Web site (not using MVC).
