Question

I know this must sound really basic but I’m really stumped here. What I’m trying to do is to show a Hyperlink once a process has completed. And this process is the AsyncFileUpload. In the ASPX page, I want to create an but have it hidden on the initial page load. If I set the Style=”display: none;” seems to work but after the file upload, nothing I do, will make the control visible again. When the file is uploaded, it calls a function called FileUploadComplete. It’s in here that no matter what I do, the Hyperlink won’t display.

Any help is greatly appreciated 🙂

Thank you,

Here is the ASPX Code (with recently added javascript)

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="OptionsPlaceHolder" runat="server">
    <script language="javascript" type="text/javascript">
        function ShowLink() {
            $("#openFile").show();
        }
    </script>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolderBody" runat="server">
    <asp:UpdatePanel ID="updImportFile" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <div class="pageHeader">           
                <asp:Literal runat="server" ID="pageTitle" Text="<%$ Resources:Resources, ImportFile %>" />
            </div>
            <ajaxToolkit:AsyncFileUpload ID="FileUpload1" runat="server" Width="600px" 
UploaderStyle="Traditional" OnUploadedComplete="FileUploadComplete" ThrobberID="throbber" 
               CompleteBackColor="#E9F2FD" OnClientUploadComplete="ShowLink" />
            <asp:Image runat="server" ID="throbber" ImageUrl="images/loading.gif" />                    
            <br />
            <asp:Hyperlink runat="server" ID="openFile" NavigateUrl="~/OpenFile.aspx" Text="Open" 
style="display:none;"/>
        </ContentTemplate>
    </asp:UpdatePanel>        
</asp:Content>

And here is the code behind:

 protected void FileUploadComplete(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile)
        {
            string importName = Server.MapPath(@"Uploads\") + FileUpload1.FileName;
            FileUpload1.SaveAs(importName);

            // Import the JSA
            JSA jsa = new JSA();
            jsa.Import(importName);

            // Show the Hyperlink
            ShowLink();
        }
    }

    private void ShowLink()
    {
        openFile.Attributes["Style"] = string.Empty;
    }

I didn’t include the master page code. It has the ToolkitScriptManager in it.

It would be more helpful if you would post some of the code you have tried already so that we can get a better idea of where you are.

[EDIT :I didn’t catch that you are using AsyncFileUpload when I first read the question]

Using AsyncFileUpload inside an update panel the server is being accessed via a partial postback, as a result other controls (the hyperlink) cannot be affected on the server. This will require that you make use of javascript (or preferably jquery) to make the change on the client.
