Hi John,

Do you want ENABLED property or you can go with READONLY? If later, just put a grid in READONLY state...

>Hi Everyone,

>For the most part, the code seems to work fine. i.e. When I move to a row that should be disabled, it is. All controls in that row are disabled. I can't select anything from the combo boxes, checkboxes etc. However, when I first move from a disabled row to one that should be enabled, the controls in the row still seem to be disabled. Even though the Enabled property of the column with the focus has its enabled property set to .T. (I checked) and so does the current control for that column, the control acts as though its disabled (i.e. you cannot type into or select a value from a combo box or change a value of any control in any way). Interestingly, if I move to another column in that same row, it is enabled and when I move back, so is the one I just left.

>Am I missing something? Is there some reason that a control would not be enabled even if its Enabled property is set to .T. (Incidently, for those who may be wondering, I've also checked the ReadOnly property which I am not setting. It is set to .F. as it should be.)
