getControlType() issue...what am I doing wrong?

The reason I started investigating how to preserve the http cookies was because when I forced the ImageUploader control to use the Java version it was redirecting to my login page when I tried to upload a file.

The default value of that PreserveHttpCookies property is True, but I tried setting it to True anyways and it did not make a difference.

When forcing the ImageUploader control to use the Java version I was able to get it to work by using this function on the OnClientBeforeUpload event:

<script type="text/javascript">  
        var iu = getImageUploader("<%=ImageUploader1.ClientID%>");
         iu.AddCookie('<%= FormsAuthentication.FormsCookieName %>=<%=Request.Cookies[FormsAuthentication.FormsCookieName].Value %>;' +
                'ASP.NET_SessionId=<%= Request.Cookies["ASP.NET_SessionId"].Value %>');
</script>  

I removed the check to see whether or not the Java or ActiveX control was loaded since I knew the Java control was going to be loaded. This seemed to work fine and the Java control was no longer causing a redirect to my login page, which was in turn causing an error.

However, I do want to use the ActiveX and Java controls.

I'm not sure why the PreserveHttpCookies property is not working, but it does not appear to be. Executing the above javascript does seem to work.

Any help would be greatly appreciated.

I am using ASP.NET 3.0. My application is using forms authentication. I am using the ImageUploader control on a User Control (.ascx). That User Control is usually embedded in another user control when it is used.

If I force the ImageUploader control to use the Java version (by setting ActiveXControlEnabled="false") when I attempt to upload an image I get the error "The server attempted to redirect you to {login page}, but server redirects are not supported."

I have set PreserveHttpCookies="true". I have also tried the following code:

<script type="text/javascript">
    function ClientBeforeUpload() {
        var iu = getImageUploader("<%=ImageUploader1.ClientID%>");
        if (iu.addCookie())
            iu.addCookie('<%= FormsAuthentication.FormsCookieName %>=<%=Request.Cookies[FormsAuthentication.FormsCookieName].Value %>;' +
                'ASP.NET_SessionId=<%= Request.Cookies["ASP.NET_SessionId"].Value %>');
    }
</script>

<cc1:ImageUploader ID="ImageUploader1" name="ImageUploader1" runat="server" Height="400"
    LicenseKey="71060-4698C-00000-05AD1-8C271;72060-4698C-00000-00CD8-D244C" Width="600"
    OnFileUploaded="ImageUploader1_FileUploaded" ShowDebugWindow="true"
    ActiveXControlEnabled="false" PreserveHttpCookies="true" OnClientBeforeUpload="ClientBeforeUpload">
</cc1:ImageUploader>

Upon clicking the Send button on the ImageUploader control this gives me the following javascript error:

Line: 2820

Error: java.lang.IllegalArgumentException: No method found matching name AddCookie and arguments []

So it is failing on the if (iu.addCookie()) check. If I replace that check with:

if (iu.getControlType() == "Java")

I get the following javascript error:

Line: 2820

Error: Object doesn't support this property or method

However, if I replace the entire javascript function with the following, everything works fine:

function ClientBeforeUpload() {
        var iu = getImageUploader("<%=ImageUploader1.ClientID%>");
        iu.addCookie('<%= FormsAuthentication.FormsCookieName %>=<%=Request.Cookies[FormsAuthentication.FormsCookieName].Value %>;' +
            'ASP.NET_SessionId=<%= Request.Cookies["ASP.NET_SessionId"].Value %>');
    }

However, this isn't doing any checking to see which version of the control (ActiveX or Java) is running. I am not sure of the implications of adding the cookie if the ActiveX version of the control is running.

I am testing all of this on IE 8.

Thank You!
