Having major problems with Microsoft.Office.Interop.Excel. This is my problemI create an XML document and then I push it to the web browser with an xls header which is all good. What I need to do is create Data Validation Lists in the XML so that when I push it to the browser and create the Excel document the drop downs in the excel document are there and are linked to the other worksheets. Does this make sense? If I need to provide code I can. Please help!
