Hi

I have mentioned the fact during the last year or so that I have seen labels, command buttons and shapes that do not always display on a form when it is first activated. However, if you click on the area where the buttons are located they will be displayed and if you minimize and then maximize the form all controls will be visible.

I have tracked the cause down to the grid control which I use for table navigation in all my data entry forms. The problem arises when I use a Method in the Column control source that return strings between 200-250 characters and there is more than 3 records displayed in the grid.

I also use the SetAll method to trigger the refresh method of the related data bound controls when the record pointer changes. I do not use the form refresh because I might have two related grids on a form and only some controls should be refreshed depending on which grid the user is navigating.

I have since changed to using a customized list box that can work on any size table instead of the grid control and I no longer experience the problem of disappearing controls.

So perhaps this information will help anyone else who may have experienced this problem.
