-
ASP.NET - File Uploading ASP.Net has two controls that allow the users to upload files to the web server. Once the server receives the posted file data, the application can save it, check it or ignore it. The following controls allow the file uploading: HtmlInputFile  - an HTML server control FileUpload  - and ASP.Net web control Both the controls allow file uploading, but the FileUpload control automatically sets the encoding of the form, whereas the HtmlInputFile does not do so. The basic syntax for using the FileUpload is: Example: The content file: <body> <form id = "form1" runat = "server" > <div> <h3> File Upload: </h3> <br /> <asp:FileUpload ID = "FileUpload1" runat = "server" /> <br /><br /> <asp:Button ID = "btnsave" runat = "server" onclick = " btnsave_Click " Text = "Save"...
