I am picking up this error in my project. i installed the latest service pack last night:
Warning 17 The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection
It is being triggered here:
this.frmMain_Fill_Panel.Controls.Add(this.frmMain_Fill_Panel.ClientArea);
Hello ,
Could you please let me know the exact version of Infragistics from which you are updated, and the exact version of Infragistics to which you would like to update? Also could you please let me know if you are using “Infragistics Version Utility” to upgrade your project.
Current: 10.3.20103.1000New: 10.3.20103.2083 (I think this is correct. Whatever SP is out there right now)
Yes, I used the upgrade facility.
I ended up rebuilding the form.
Mark this as closed since I rebuilt the whole form. I didn't have time due to a conference deadline so I had to act immediately.
Hello,
Thank you for provided feedback. I am glad to hear that you were able to solve your issue. Please let me know if there is anything further that I could do for you.
Thank you .
I had the same problem after upgrade version 12 to 13.
What can I do for resolve the problem ?

The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection instead.
