I’ve narrowed it down to the configuration that causes the error. Setting Sorted = True under StrataFrame Item Population for an Infragistics UltraComboEditor will cause an exception when you click on the control to display the drop down list. It should be easy to reproduce.

Bah, yes, the IgnoreManageUIReadOnlyState property was not fixed in the 1.6 release... the work item for it got bumped to a different page in the report.  As for having to delete the ComboEdit... that's strange.  I'll have to look into it.

That’s it. The project compiles with no errors but when I click on an ultra combo editor control I get the null exception. Closing the exception window causes another null exception to be displayed (one for each UCE on the form). Simply re-configuring the existing UCE doesn’t work. The control must be deleted, re-added to the form, and configured for it to work.  

 

On a related topic, I noticed that the Infragistics controls still default to IgnoreManagedReadOnlyState = True which is just the opposite of the SF controls.

So, when you delete the control from the form and re-add and re-configure it, the NullReferenceException goes away?  That's very curious.

Regarding my previous post, so far the problem seems to be limited to the Infragistics UltraComboEditor. The ListView and Masked text Boxes appear to be OK.

After upgrading a project from SF v1.5x to v1.6 I’m having problems with the Infragistics controls. I have Net Advantage 2006 vol 3 installed on the system and have added the references to the updated DLLs to the project reference list. Everything compiles OK but I’m getting an error when I try to access a Infragistics control. If I delete then re-add the control it works okay.
