RadToolTip Dynamic hyding and showing client errors

[Mark]

I have a RadTextBox which is dynamically hidden and shown.  I also have a RadToolTip for this textbox.  The problem occurs when i am dynamically hiding the text box which has the tool tip.  I get client errors.  This doesnt always occour but i think it is if the tool tip is open when the textbox is been hidden.  In the main page i am using i get 'style' is null or not an object.  In the example i have put together for posting i get 'offsetParent' is null or not an object.  Can anyone advise how i might get round this. 

Thanks for the help.

Mark.

Was this issue resolved? I am also facing the same issue. If the solution has been found, please let me know. BTW, this issue happens only in IE6. No issues with IE7 or Firefox...The version I use is 2008_3_1105

Hello guys,

I built up a test demo project based on the provided code, I tested it with the 2008.1 415 version of RadControls
and I was able to reproduce the problem which is caused by hiding and showing the target control of the tooltip as Mark correctly assumed himself. However, this version is very old and a lot of improvements and bugfixes were applied to RadControls since it was released and this problem is already fixed. I tested the very same demo project with the latest build, namely 2008.3.1125 and everything worked as expected, no error was thrown.

Panchapakesan, I tested the sample demo with the 2008.3.1105 version of RadControls and under IE6 but I was not able to reproduce the problem - that is why I assume that even if you get a similar error, it is caused by a different setup and I will need to examine this setup. Please, upgrade to the latest built of RadControls and if the problem still persists, download the attached test demo, modify it in order to reproduce the issue, open a new support ticket and send it to me along with detailed reproduction instructions and explanations.
