Hi,
Since posting my question I have managed to get it working by setting the action to a different page.
The new problem is that the upload sub is always being called even when it is just a normal postback. It then loses all the postback events i.e. just shows a blank page and the page_load event is never fired.

Do you upload at the same time files using <asp:FileUpload > element? Here is source code of Image Uploader control where it handles file upload: Code:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
if (Page.Request.Files.Count > 0)
{
for (int i = 0; i < Page.Request.Files.Count; i++)
{
HttpPostedFile file = Page.Request.Files[i];
FileUploadEventArgs args = new FileUploadEventArgs(file);
OnFileUploaded(args);
}
HttpContext.Current.Response.End();
}
}
As you see, if request contains some uploaded files, then it raise FileUploaded event for each file and then ends response ( HttpContext.Current.Response.End();). After no other page events are raised.

I think the problem may be HttpContext.Current.Response.End();
I was posting back to the same page and this would have effectively stopped it. I have used a different solution so I won't be able to test if this would actually work or not.
One thing I did struggle with was how to get the descriptions in the postback?

You can try to replace in control source code: Code:if (Page.Request.Files.Count > 0) to Code:if (!String.IsNullOrEmpty(Page.Request.Form["PackageGuid"])) Image Uploader always send PackageGuid field in post request. We will fix in next control release. Quote:One thing I did struggle with was how to get the descriptions in the postback Description is stored in Request.Form["Description_ N"] field of request. You can get access to it at any time.

Good day.
I'm using Visual Studio 2008 and control does not render in the designer. The error shown on the control is:
Error Rendering Control - ImageUploader1
Request is not available in this context.
I have checked the reference to the dll.
It works in VS2005.
Please assist.

I confirm the problem. I will prepare update ASAP.

It works in VS2005. You need to change in OnInit of ImageUploader (ImageUploader.cs) from: Code:
base.OnInit(e);
if (Page.Request.Files.Count > 0)
{
for (int i = 0; i < Page.Request.Files.Count; i++)
to: Code:
base.OnInit(e);
if (!DesignMode && Page.Request.Files.Count > 0)
{
for (int i = 0; i < Page.Request.Files.Count; i++)
I will include this fix to next major ASP.NET control update.

Hey all, I am new to the Aurigma product and trying to figure out something. I want to use the ASP.NET control version to place the upload tool in my ASP.NET page. I can do that using the basic control example as outlined on this site but what I want to do is to be able to customize the preview pane to allow the user to be able to enter in several fields worth of information. I've looked at the Multiple Descriptions Sample and are able to make that work using a javascript-based approach. My question is how do I do so using ASP.NET controls? I've tried to simply substitute the <script>....</script> section in the body of the sample page for an <cc1:ImageUploader>...</> tag but it does not seem to show the preview pane when I do this approach. Can someone assist in how to have a template visible for each image that is being uploaded in the pane at the bottom so I can have the appropriate input entered wit the photo? Thanks, Robin

Hello,
I think it is better now to go forward without ASP.NET control. You should implement it the usual way using iuembed.js script. Just see Multiple Description sample and go forward with it.

Iam trying to use the multifiledemo .. i have set it up...
first thing is it doesnt allow the drag and drop...
second thing is how do i call the ImageUploader1_FileUploaded() method ... i dont know if i need to add a event in the java script? which i have done like this
iu.addEventListener("OnFileUploaded", "ImageUploader1_FileUploaded").... still the code aint reaching the ImageUploader1_FileUploaded ....
So iam getting the files in the Page_load which i dont like because the first time the page is loading i dont have no files and so it throws an error... but iam implementing it in a wrong way with blank Catch( ) i,.e catching error and doing nothing...
third thing i need to know is how to show the error message ... or change the message that the java script throws like File Uploaded... i need to chnage those..
and say soem thing like Upload complete.. and do some thing else or better redirect them to another page without even showing that alert of filesuploaded...
Thanks in Advance :)
Bob
