I have a GridControl and GridDataboundGridControl on the same form (both are contained within a panel) and occasionally after running the application, the Grids no longer appear on the designer.
The grids still show up in the list of objects that are part of the form, but are not visible in the designer, and can''t be seen when the application is running either.
Only solution seems to be to manually delete the grids from code and drop them on the form again, but this is very annoying, and impractical. I don''t see anyone else having this problem. I am setting the dock property to fill at run time. Not sure if this is the reason or not.
Are these grid''s derived grids? If so, before opening up the deigner showing this form after you initially load the project into VisStu, you should always make sure you rebuild the project first. (So, never close your project with the designer opened, an dthen immediately build it the next time you load it.)
You can also lose controls like this if you do an update of our libraries as the version changes. This has to do with versioned resources and will occur more often if you use the designer to set style properties or column widths or row heights for a GridControl.
