BTW - Another bit of information.  None of the styles on any of my infragistics controls are getting applied during an initial page load.  I have the tree control, a grid, and a popup menu and none of the default styles are getting applied.  Just thought that might help narrow it down.

Thanks again,
Dale

Hey Ivan,

Any idea on this one?  You mention there are many reasons why this can happen.  Can you give me some of these reasons?  I can then go see if any apply to my scenario.  Are there any known issues with 2008.1 targeting framework 2.0?  Are there fixes for these types of issues in 2008.3?  I thought I would hit the forums before opening a support incident, but I can certainly do that if necessary.

As always, any assistance is certainly appreciated.

Best Regards,
Dale

Thanks Ivan, I completely understand.  It's hard to test what you can't see.  Unfortunately, I haven't been able to reproduce in a simplified project and I can't really upload the whole thing.  So, I'll give you what I can.  Remember, I'm working with 2008.1 (no hotfixes or patches) and I'm targeting the 2.0 framework with Visual Studio 2008.

Below the Register Assembly directive (I included it so you could see the version information) is the declaration for the Tree, some of the code behind and some of the javascript.  The tree is declared inside a splitterpane, which is inside an ajax updatepanel.  I'm also using a MasterPage and the page with the tree is a content page.

If you need anything else, just let me know what you want to see.  I wouldn't mind upgrading to 2008.3 if I knew it would solve the problem.  I'm just hesitant to do that as an initial step because in the past I upgraded to a more recent version to solve one problem and the newer version actually introduced a few new problems.

So, with all that in mind, take a look and see what you think.

Any assistance is certainly appreciated.

Best Regards,
Dale
