Even with enabled_assign method, you may want to have either a separate class, or an additional property, which will keep the state of your textbox. I have such a property named .Say (as a reminder to the behavior of @x,y say var of non-V versions of Fox), which comes in handy when you need to disable all the controls on the form (except maybe a few) and then want to re-enable only some of them. In my case, those with .say=.t. remain disabled. So in Enabled_assign I could have something like

this.enabled=m.vNewVal and not this.say

so I could do thisform.setall('enabled',.t.) and the textboxes would get enabled as I want them.
