>Notice that when moving from a grid to another object on the form, the grid's Valid fires before the valid of the active cell. This is a bug. Normally you would expect to use the control's Valid method to determine whether that control can lose focus. However, when a control is contained within a grid, there are two levels at which focus operates. First, the focus works between the control and other controls within the grid. In this context things behave normally.

>Second there is the issue of which form object has focus. This bug will bite you when focus is being moved between the grid and another object. It is, as you would expect, the grid’s Valid method that determines whether the grid can lose focus. However, because the grid’s Valid is called before any contained control, a contained control cannot prevent the grid from losing focus even though its own validation has failed.

Fortunately, there is an easy workaround, which ensures that the grid’s Valid explicitly calls and returns the result of any contained control’s validation. So if the text box in the first column of the grid has code in its Valid, this line in the grid's Valid method takes care of the problem:

Great tip. And if you have many columns, you guess must use

RETURN This.Column1.Text1.Valid() and This.Column2.Text1.Valid() and This.Column3.Text1.Valid() ...

Is there any easy way to make this change in my grid baseclass?
