Hi,
We are not aware of any such problem. Can you create a test page that reproduces the problem? Make sure it runs independently. We will be happy to take a look of that as soon as we have the test page.
Thanks!

Hi,
We run the page and tested it on IE 6, IE 7 and FireFox. Neither hit the "not a postback" case. We tested with build 2008.0.44 (6.0.44).
Can you check whether you are on the same version? Or see if you get the same result from another machine?
Thanks

We did. We do not see any such issues. Can you try it in a blank project?

Hi,
We will need to take a look on your machine then. We can setup an online meeting so that you can share your desktop with us. Please let us know if you would like us to do that.
Thanks!

Hi Rick, I believe the issue has been resolved in our latest build. Which version are you currently running? See the following post for more information about how to find out the version number: http://www.essentialobjects.com/forum/postst2942_How-to-find-out-EOWeb-Controls-build-number.aspxThanks!

Great, I will check and post the version number as soon as I get back to the office this evening. Do you know where I can download the latest version?

Hi,
You can always download the latest version from our download page (click Download from the main menu). Once you download the new version, you will need to:
1. Uninstall your previous version and reinstall the new version;
2. Update your application's reference so that it references the new EO.Web.dll other than the old one;
3. Rebuild your application;
4. If you already have a license, you will need to go to "My Orders" page to download a new license file for the new version. This is usually not necessary but we have just released 7.0 (7.0 = 2009, the previous version was 6.0 = 2008). The new version is backwards compatible but requires a new license file. You should be able to download the new license file for free if you have purchased your previous license within a year;
Please feel free to let us know if you still have any questions.
Thanks!

Hi,
Thanks for the additional information. We will look into it and get back to you as soon as possible. (The original problem Satrebla was having was with the Editor control, not with the Uploader control. I believe that one has been fixed)
Thanks!

Hey Guys,
It worked and you don't know how thankful I am. This is the third ajax downloader control I have bought. The truth is, it is so far superior to the others in terms of both user experience and ease of implementation that I would have preferred it even with the bug. The fact that you guys fixed it over the weekend is just amazing to me after the trials I've been through even getting support to respond with the other companies.
You guys have a great product with great support. I will be recommending Essential Objects to all the programmers I know. Thanks for making my weekend!
Rick

Hi, I have the same problem. I just installed version 2009.0.16 but it did not reolve the problem. Did you put the fix in this release?

Hi,
I believe this build does include the fix. If you still have problem, then it might be a different but similar problem. In that case please provide a test page that can reproduce the problem and we will be happy to take a look.
Thanks!
