I have a single single text field and button on a non database block. Initially the button is disabled, but when text is entered into the text field the button to be enabled. How would I be able to achieve that? any help is appreciated.

Try with WHEN-VALIDATE-ITEM on text item, and use SET-ITEM-PROPERTY built-in to modify button's properties. Have a look at Forms Help for more info.

I did try that, the when-validate-item doesn't seem to fire, because i think since there is only one field, no where to tab out for that trigger to fire?

If the button is keyboard navigable, then there is somewhere to tab out.

The button is disabled at the start, so isn't navigable until after WVI fires.
I think in this case you're just going to have to leave the button enabled and have the when-button-pressed check if a value has been entered, if it hasn't raise an error telling the user to enter a value.

Gosh! Silly me! /forum/fa/3518/0/

That's what the whole discussion is about! A major deconcentration ...

But tabbing will just go to the same field and WVI will fire.

What are you actually trying to achieve?

Other than what I said, what cookiemonster said is the best solution.

Unless the cursor actually moves somewhere else, WVI won't fire. If you've got a single record block with a single enabled item the cursor has no where to go.

When I press Enter or Tab, the WVI runs for me.
I created a dummy form based on a non-database block, one text item, one button. button is disabled and navigable is set to NO for keyboard and mouse. WVI fires if I hit either key as soon as the form starts, or after I change any value in the text item.

I'm surprised but fair enough. Presumably that's not happening for the OP though.
So:
1) What version of forms are you using?
2) What is your form level Defer Required Enforcement property set to?

@mforms - same questions for you.

Cookie, I tried in both 6i and 11.1.2.2.0.
Defer Required Enforcement is set to No in both.

Then the obvious thing to suggest to the OP is that he sets Defer Required Enforcement to No.

Thanks for testing - I don't have a working forms installation to do it myself.

Do you have a non-working forms installation? /forum/fa/1587/0/
