Hello,
Have you specified thumbnail parameters in your aspx page? Could you list the page source here?
Sincerely yours,

Hi,
I have downloaded a trial version of the image uploader as well as this asp.net control. It works fine in my localhost and able to upload files. However, when I did exactly the same installation to our web server it came up with an error "No valid license key for current dns/ip address specified" I have sent a support email and was told to insert the trial license key parameter. I'm not sure where I should insert this since I'm using the asp.net control.
Please advice
Thanks
Anson

Another question. Is there anyway to use this asp.net control to retrieve the description text entered? There doesn't seem to be a property for it at the moment.

Hello, The only way to get descriptions is to extract them from POST request fields in the FileUploaded handler. You need to get Description_N fields values (for example, Request.Form["Description_1"]). Please, read POST Field Reference and Writing Server-Side Upload Code for additional information.
Sincerely yours, Dmitry Sevostyanov.

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. After that according to ur suggestion given to somebody, i changed the code in onInit method of ImageUploader.cs from base.OnInit(e);
if (Page.Request.Files.Count > 0)
{
for (int i = 0; i < Page.Request.Files.Count; i++)to base.OnInit(e);
if (!DesignMode && Page.Request.Files.Count > 0)
{
for (int i = 0; i < Page.Request.Files.Count; i++)and made a new dll. After consuming the new dll, it's giving same error as mentioned above. Please tell me the solution as soon as possible. With Best Regards, gaurav malik File Attachment(s):

Hello, I just modified the code in the same way as you described in your post and it worked great for me in VS2008. I did the following: - Opened ImageUploader.cs and modified OnInit method:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
if (!DesignMode && 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();
}
} - Closed my sample project in Visual Studio.
- Recompiled Aurigma.ImageUploader.dll and put it into /bin folder of my sample project.
- Opened my sample project.
It works okay. Please, find the updated Aurigma.ImageUploader.dll in the attachment. File Attachment(s):
Aurigma.ImageUploader.dll (162kb) downloaded 17 time(s).
Sincerely yours, Dmitry Sevostyanov.

BeforUpload is not working. It's not being called server side. <cc1:ImageUploader ID="ImageUploader1" BeforeUpload="ImageUploader1_BeforeUpload" runat="server">
</cc1:ImageUploader> Protected Sub ImageUploader1_BeforeUpload(ByVal sender As Object, ByVal e As Aurigma.ImageUploader.FileUploadEventArgs)
End Sub How would you use ImageUploader1.BeforeUpload ?

Hello, Quote:BeforUpload is not working. It's not being called server side.
<cc1:ImageUploader ID="ImageUploader1" BeforeUpload="ImageUploader1_BeforeUpload" runat="server">
</cc1:ImageUploader>
Protected Sub ImageUploader1_BeforeUpload(ByVal sender As Object, ByVal e As Aurigma.ImageUploader.FileUploadEventArgs)
End Sub
How would you use ImageUploader1.BeforeUpload ? Could you post here or submit case with entire page code?
Best regards, Fedor Skvortsov

<cc1:ImageUploader ID="ImageUploader1" BeforeUpload="ImageUploader1_BeforeUpload" runat="server">
</cc1:ImageUploader> The JavaScript is called and not server side for ImageUploader1_BeforeUpload. I added this to the page for a test. The Javascript is being called and not the server side code. I fixed my problem using AJAX but it would be nice if the control would take care of it. Thanks <script type="text/javascript">
function ImageUploader1_BeforeUpload(){
alert('not on server');
}

Hello, I am sorry, I have not paid enough attention to the fact that you use client-side only BeforeUpload event. There are numerous client-side events, and only one server FileUploaded event. You try to use client-side event on server side, but it doesn't work due to design. If you want to handle uploaded files, please use FileUploaded event: <cc1:ImageUploader ID="ImageUploader1" runat="server" Height="350px" Width="630px" OnFileUploaded="ImageUploader1_FileUploaded" ShowDebugWindow="True" />
Best regards, Fedor Skvortsov
