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.

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.

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.

I was wondering if you were able to reproduce this issue. While I can develop in v1.6 it’s preventing me from actually using 1.6 in production.

Ben,

Thanks for looking into this. I did some more checking and found that I could reproduce the problem using the DataBinding VB sample that is distributed with the Net Advantage Suite… looks like it is definitely their problem. I’ve submitted a support request with them.

I guess I spoke too soon. I was able to reproduce the problem using one of their sample applications but they say they can’t reproduce it on their end and sent me back a sample application to try.  The sample they sent populated the UltraComboEditor directly and I was able to run it with no errors. It appears that the control must be bound to cause the error. I created an updated sample and sent it back to them and I’m still waiting for a response. They are no where close to providing the level of service that you guys do The sample is simple, just an UltraComboEditor on a standard Windows form with the following code in the form’s load event.

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim letters = New String() {"B", "A", "C", "E", "D"}

        Me.UltraComboEditor1.SetDataBinding(letters, "")

End Sub

Using that sample produces a null exception if SortStyle is set to anything other than “None” when run against 2006 Vol 3, Vol 2 runs okay.  If you guys have priority support with them you might try to see if you can get them to look at it. Since 2007 Vol 1 just came out I recompiled the SF wrapper for that version and so far everything looks okay.

And, no, I don't think we have priority support, sorry, we have to wait in the same bucket as you do.

I just received another reply from Infragistics tech support saying that they cannot reproduce the error. Since I haven’t seen any postings here of a similar error, maybe it’s something in my environment.  I tried uninstalling vol3, downloaded a new copy, re-installed and still received the same error. However since you were able to reproduce it using their standard distribution but not against their compiled source code I’m assuming that it’s something in the distribution or installation.  Since 2007 vol 1 seems to be functioning normally I’m going to forget about 2006 vol3 and move on.

For anyone else that may have experienced this problem, Infragistics was finally able to reproduce it. Installing NetAdvantage HotFix 6.3.20063.1059 fixes it.
