AJAX Upload

Hello:

I am using .Net 4.5. When I use the AJAX FileUpload,the files upload to the directory ok but the Label1.Text and Label2.Text do not fire. I do not get an error message even though I use try catch.

    <form id="form1" runat="server">
        <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" />
    <div>
        <asp:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="mp4" OnUploadComplete="AjaxFileUpload1_UploadComplete" runat="server" />
    </div>
        <br />
        <br />
        <asp:Label ID="Label1" runat="server" />
        <br />
        <br />
        <asp:Label ID="Label2" runat="server" />
    </form>

Open in new window

        protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
        {
            try
            {
                AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + e.FileName));
                if (e.State == AjaxControlToolkit.AjaxFileUploadState.Success)
                {
                    Label1.Text = e.FileName;
                    Label2.Text = e.FileSize.ToString();
                }
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message.ToString());
            }
        }

That sounds like e.State is not Success, but there is not an exception.  Can you check the value of e.State?

Yes e.State is not a success so when I took it out, it give me the same result the files were uploaded but nothing happened with Label1 and Label2. I even tried something like this Label1.Text = "Successful Upload!"; thinking it maybe the e.FileName. Still no result or error.

            try
            {
                AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + e.FileName));
                    Label1.Text = e.FileName;
                    Label2.Text = e.FileSize.ToString();
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message.ToString());
            }

What happens if you are in debug mode, and you comment out the try/catch block?  If you put a breakpoint on the SaveAs line, does it step passed that line to the Label1.Text line?

I deleted the try catch and commented out the upload. The files do not upload to the folder but the labels do not display either.

I added a button just to see if where was a problem with the labels and when I click on the button the labels show there respective texts.

    <form id="form1" runat="server">
        <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" />
    <div>
        <asp:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="mp4" OnUploadComplete="AjaxFileUpload1_UploadComplete" runat="server" />
    </div>
        <br />
        <br />
        <asp:Button ID="ButtonTest" Text="Test" runat="server" OnClick="ButtonTest_Click" />
        <br />
        <br />'
        <asp:Label ID="Label1" runat="server" />
        <br />
        <br />
        <asp:Label ID="Label2" runat="server" />
    </form>

        protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
        {
                    //AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + e.FileName));
                    Label1.Text = e.FileName;
                    Label2.Text = e.FileSize.ToString();
        }

        protected void ButtonTest_Click(object sender, EventArgs e)
        {
            Label1.Text = "Label 1 Works!";
            Label2.Text = "Label 2 Works!";
        }
    }

Is that the version that you are using now?  Maybe it is because I am a little tired, but I missed something important that you saw...

Stephen, looking at the upload control, it seems it can only be used for uploading the file, and cannot be used in combination with a form (i.e. set a few controls, select file(s) for upload, submit). Is this true? If so, that’s a very limiting design choice and makes the control far less useful that I was hoping.

@Michael – yes, the AjaxFileUpload is async. It would be hard (impossible?) to display progress if we did not make it async. Also, we could not break the file into multiple chunks.

True, but as we discussed on Twitter, you can keep it async and still do a post at the end of upload.
