Hello Gloria.

- in 'Grid.SetAll', it should be:
LAPARAMETERS cProperty, Value, lselected

This statement:

LPARAMETERS cProperty, Value

Should appear at the top of the setall method by default.

If not, it is because you have done something to over-write the method in your class or form. In order to correct it, all you need to do is to select the grid in the designer and right-click the SetAll method in the property sheet and select Reset To Default from the context sensitive menu,

- in 'Grid.Column3.Check1.Click', it should be:
ThisForm.Grid.Refresh()

The row would have changed color anayway as soon as you navigate to a new row in the grid or a different object on the form. Yes, refreshing the grid explicitly makes it happen immediately < s >.
