Add Control to PictureEdit

Question

After adding a UserControl to Picture Edit control of DevExpress, i was able to successfully place it over a location and save the changes.

After reopening the application, when i populate the PictureEdit with the image and then add the UserControl to pictureEdit controls collection, error image is displayed in the PictureEdit along with message "Object Reference not set to instance of an object" -> null reference.

System.NullReferenceException: Object reference not set to an instance of an object.

   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

But if I ndo not add UserControl to controls collection the the image is displayed perfectly but then i am missing my user control over the PictureEdit.

Any suggesstions?

Force create your control.

picEdit.CreateControl();
