Question
ASP.NET Reponse.Content help with selecting and uploading file
Hi, I'm using asp.net and a gembox Excel DLL to read/write excel files. The writing aspect works well using the following code, which prompts the user where to save the file.
//ef is the ExcelFile object.
Response.Clear();
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Conten
ef.SaveXls(Response.Output
Response.End();
Now, I need to figure out how to read the file using the ef.LoadXls function. It works fine if I hardcode the file to the local machine, but how do I get it to prompt the user through the web interface and allow them to select/upload the file?
Thanks,
Terry
