Hi I wonder if you ever found a solution to this problem as I have the same issue?

Thanks

Zack

I have just found out the problem in my environment. 

I forgot to copy the new javascript files to my application after the update.  They have changed between versions 7.1 - 8.3.

I also had to clear my tempory internet file cache as i have caching enabled on my machine.

I hope this helps somebody in the future.

Thanks for the help!

Could you explain more how you copy the new JavaScript files?  As far as I can tell, I have not added any Infragistics JavaScript files to me project.  Where do you find them at?  How do you know if you are using old versions of JavaScript files?

I know that some JavaScript files are generated when I run my project.  Is that what you are talking about?

yes i think these files should be automatically generated when they are needed.  However because i carried out on update the old javascript files were still in my web application.

an example of these files are:

ig_WebGrid.js

ig_webtoolbar2_2.js

if you open them in a text editor then it should tell you the version number at the top like this.

/*
* ig_WebGrid_an.js
* Version 8.3.20083.2039
* Copyright(c) 2001-2009 Infragistics, Inc. All Rights Reserved.
*/

OK.  We also did an upgrade to 8.3.  So, how did you tell it to use the new JavaScript file? 

Sorry, I am new at this. :)

no problem.

In our web.config we have an entry which specifies which javascript files to use.

<

infragistics.web javaScriptDirectory="~/ig_common/JScripts">

</infragistics.web>

if you update the javascript files in this location with the new ones that should be enough.  Maybe you have to delete the cache before the changes will take affect.
