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

Hi there !

I'm having HUGE issue with the UltraXXXXX controls from Infragistics now ...
I'm using VS 2008 ( also tried VS 2010 ) and the IDE has become completely messed up!

I'll send a screenshot to show you what has happened ... all the UltraXXXXX controls are like this, and if I create a new form, and drag e.g. UltraGrid into the form it appears at the bottom ( the same place as BindingLists, ErrorProviders etc should appear ). But this does not happen  But this does NOT happen to completely new empty WinForms project I create ... I can drag the controls correctly to that form.
Could this have something to do with the project file ?!

And I get this error in the IDE:
The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.Controls collection instead

I'll attach a zip file which shows you the screenshots of these errors ...

I've already tried deleting the bin\debug folder and obj  folders ... and "clean solution".
Attention: The project builds just fine, but it gives me this same error ( see screenshot 02 and 03 ) at runtime as in design time.-

Please contact me asap, this is stopping our whole development with Infragistics products

Kind regards,
EE

p.s. I've also tried installing VS2010 Ultimate to open up the solution ... in converts the solution just fine to 2010, but it gives the same error.-   

 

This error in the IDE happens for both Infragistics v10 and v9.2 ... I've also tried dropping them into the Forms.-
