Winforms 2011.2 at the moment but doesn't seem to matter what version.
Trying to open a windows form in Visual Studio 2012 pro (c#) and getting errors that the UltraPanel is read-only and when trying to build it generates:
"The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection instead." and it highlights this section of code in the designer file:
this.pnlLeft.Controls.Add(this.pnlLeft.ClientArea);
Changing to ClientArea like the error suggests, errors out with a circular error.
What is going on here?
Hi,
I have still the same problems since i change to the version 12.1,
please helo me to find a solution to solve the problem.
I checked it on two machines with visual studio 2010 - on both machines the same problem
Hi Admin,
For instances where controls appear within the component tray of Visual Studio, the cause is generally an issue with either the designer assembly or mismatched versions of the assemblies being referenced simultaneously by the project.
I recommend first, to check each of the assembly references to ensure that all assemblies belong to a consistent volume and that there are no duplicate assembly reference. Next, for each of these assemblies, set their associated “Specific Version” property to false and delete the contents of the licx file for the project.
After the above process has been completed, close the designer pane, clean and then build the project.
I still suggest eliminating the circular reference as that line of code is not necessary; nesting an UltraPanel within another panel follows the same format as placing any other control into its Controls collection.
If the issue persists after that point, I will require further information in order to determine the root cause, was there some process that preceded this behavior?

Sorry - problem with the image attachment.
I am not trying to manually add to the client area ... that's why this is a little weird. I have a windows form with 3 ultrapanels - left, center, right. There are various other controls placed in those panels like explorerbar, etc. In vs 2012 ide when I open the form and try to select the actual left panel, nothing gets selected. It's on the form but you can't select it. But, on the bottom panel area - place where menu's, status bars, binding sources, etc. get placed .... the panels are listed there. I can select the left panel there and voila, I can edit the properties.
Does that make sense?
