Post filename in label from Fileupload control – ASP.NET 4.0 C# – Education Career Blog

Is there anyway to run an event after i selected a file in a Fileupload control, so i can set Label1.Text = FileUpload.FileName;

Or if any of you got another idea that would be awesome too(maybe some javascript)! 🙂


You can listen for the change event on the client side. Here’s the syntax for IE but you can adapt it for the better browsers.

    <asp:FileUpload ID="FileUpload1" runat="server" /> <span id="txt" />
        var fu = document.getElementById('<% =FileUpload1.ClientID %>');
        fu.attachEvent('onchange', function (e) {
            document.getElementById('txt').innerHTML = e.srcElement.value;

I’m pretty sure good browsers will report only the filename, where IE with report the full path too (incorrectly).
