Hello everyone,

I recently moved from V12.2 to V13.1 and I am getting the following error:

An error occurred creating the form. See Exception.InnerException for details.  The error is: The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection instead.

When I click on the call stack, I find:

at Infragistics.Win.Misc.UltraPanel.UltraPanelControlCollection.Add(Control value)
at System.Windows.Forms.Design.ControlDesigner.DesignerControlCollection.Add(Control c) 

When I click "view detail", I get:

{"An error occurred creating the form. See Exception.InnerException for details.  The error is: The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection instead."}

When I click copy exception detail to the clipboard, I get:

System.InvalidOperationException was unhandled
HResult=-2146233079
Message=An error occurred creating the form. See Exception.InnerException for details. The error is: The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection instead.

InnerException:

Honestly, since it will no longer load up correctly (no idea what happened/what I did, it used to work just fine and I don't think anything has changed apart from my Infragistics version), I don't really know what to change or where to start.  Can anyone point me in the right direction?  I'm guessing the answer is in the last bit of info I pasted but I'm having trouble reading what it's trying to tell me.  

If you need any additional information, let me know.  Thanks!
