post-back when the filename to upload changesHi;
Is there a way to do this? I want to get a post-back if the file to be uploaded changes. I am thinking if I have a javascript variable with the string in the filename text box. And then a javascript function is called when leaving the filename textbox or when the browse button places a new filename in the textbox – the javascript then does a post-back if the text content has changed. Would this work? And do you think it is a good way to handle this? What I show on the page depends on the content of that uploaded file. You might get answers to this in a JavaScript newsgroup.

The ASP.NET 2.0 upload control actually encapsulate the html <input type="file" name="file1" ..../> element. And if you want to do some thing when the client user change the file to upload, you can register the "onchange" client-side event of the input file element. e.g: ==================== ................ <script language="javascript"> function file_onchange(file) { alert(file.value); document.forms[0].submit(); } </script> </head> <body> <form id="form1" runat="server"> <input type="file" id="file1" name="file1" runat="server" onchange="file_onchange(this);" /> ....................... ====================== The above page use a script function to postback the page when the user change the filename o the upload html element. Hope this helps. Regards, Steven Cheng Microsoft Online Support Get Secure! www.microsoft.com/security (This posting is provided "AS IS", with no warranties, and confers no rights.)
