Enabled condition not working

I have a property called: DBSERVERNAME, this is tied to my edit box like this:

enter image description here

Now I want the "next" button to be disabled, if that textbox is empty, and the underlying variable DBSERVERNAME has no value.

So I created a condition like this :

enter image description here

But nothing happens, how can I ensure that the button is disabled if the DBSERVERNAME property has no value?

Solution

  • Control Conditions like this are best specified in pairs. Think of it like a series of conditions and actions. So your highlighted condition will sometimes enable the control, but nothing will ever disable it.

    You need to add a Disable control condition with the complementary condition Not DBSERVERNAME. While you're there, I would suggest replacing DBSERVERNAME<>"" with just DBSERVERNAME, as an empty property evaluates as false, and a non-empty property evaluates as true.

    Note that if you extend your scenario to cover multiple properties, you will want to combine them into a condition for a single Enable control condition, rather than adding multiple control conditions, to avoid enabling the control when only one of several required conditions are met.
