i Have an excel spreadsheet I create programatically with infragistics controls, ASP.Net 2.0 VB.Net. After the workbook is created, I want to send it to the client giving them the option to open or save it. All clients have Office 2007 installed. I would like to do this without saving the file to a disk on the server. Is there a way to go from the workbook object to saving the file onthe client side?
