#8712 review Bug
CKEditor.NET 3.6.1: ASP.NET MaintainScrollPositionOnPostback=true does not work for links after update panel if CKEditor is present on page
| Reported by: | dpomt2 | Owned by: | kaga |

| Component: | Server : ASP.Net | Version: | 3.6.1 |

Description
In ASP.NET there is a page directive to enforce scroll position after (either full or partial) postback. Scroll position is wrong if postback is triggered by a link button that is located aftern an update panel and if there is a CKEditor.NET control on the page. If you remove the CKEditor.NET control, scroll position is correctly after postback.
To Reproduce, create web site with ckedior in subdirectory, reference to CKEDitor.NET control and create a srolltest.aspx page with the following content. Display the page, scroll to the botton of the page and hit the link. Postback will be done and scroll position is wrong after postback. Repeat the test after removing the CKEDITOR.NET control from the aspx and scroll position will be ok.

Sorry for getting back so late.
@kaga I have tested 8712.patch with current 3.6.4 - fix works great. Would you please integrate it in the official release and provide this ASAP? Thank you.
@wwalc the issue is easy to reproduce - just create a new ASP.NET website in VS, add the scrolltest.aspx attached to this ticket, call this scrolltest.aspx from any browser (reproduce it here with IE and Firefox), scroll down to the end of the page, clickt at one of the two last link. Without the fix, after clicking one of the buttons a postback is done and scrollposition is wrong. With the fix, the scrollposition is correct.
I was not able to test the fix with 3.6.1 since the patch seems not to be suitable for this old release (CKEditorControl.cs is different at the lines of the patch). With 3.6.4, patch was easy to apply and worked as mentioned previously.
I am unable to reproduce the issue using the attached sample.
@dpomt2 - can you check the attached file and let me know how to reproduce it? And in which browser the issue occurs?
