>yes, i have the spacre=.f., the thing is that when i call the refresh of the form the whole column of buttons turns enabled/disable, intead of the button in the row that i clicked the checkbox...

How exacly did you specify the column CurrentControl?

In the Init of the grid put

this.colButton.DynamicCurrentControl = [iif(myTable.MyField,myEnabledButton,myDisabledButton)]

Enabled and Disabled buttons should be placed in the column in design-time.

Did you try that? I will try it in the evening as well...
