Question

I have used Ajax Async File Upload in UpdatePanel, It shows that file has been uploaded but it doesn't hit Uploaded Complete Event.

 protected void FileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
    {
        HdnFieldHasFileUploaded.Value = "1";
    }

why ?

Hi StackUnderflow,

The following sample works fine on my side, AsyncFileUpload UploadedComplete event could fire. You could refer to it.

<script>
    function uploadComplete(sender) {
        $get("<%=lblMesg.ClientID%>").innerHTML = "File Uploaded Successfully";
    }
    function uploadError(sender) {
        $get("<%=lblMesg.ClientID%>").innerHTML = "File upload failed.";
    }

</script>

<div>
    <asp:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete"
        runat="server" ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern" CompleteBackColor="White"
        UploadingBackColor="#CCFFFF" ThrobberID="imgLoader" OnUploadedComplete="AsyncFileUpload1_UploadedComplete" />
    <asp:Label ID="lblMesg" runat="server" Text=""></asp:Label>
</div>

protected void AsyncFileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
    System.Threading.Thread.Sleep(5000);

    string filename = System.IO.Path.GetFileName(AsyncFileUpload1.FileName);

    AsyncFileUpload1.SaveAs(Server.MapPath("FileUploads/") + filename);    

}
