Option Group Issue for a newbie

[DNA2Fly]

Newbie to VFP. How do I take an option group (such as a Yes/No question would use) and:
1. If "Yes" selected, activate a text box/list box/other
2. If "No" selected, deactivate a text box/list box AND move to next field

Also, this applies to use in a check box....

THANKS!

Put this in InterActiveChange event of the OptionGroup:

*** Assuming Yes is the first option and no is the second one
thisform.TextBox.Enabled = (this.Value == 1)

For yes/no you should use a Checkbox. If checked, then the response is Yes.

Both are valid representations and are found in desktop and web applications. You'd perhaps prefer a Checkbox, as it's more natuaral to bind a boolean field/value to it in VFP than to an optiongroup with two options, because the checkbox may have values .t./.f. (true/false), while the option group would be 1 or 2 and you'd need to translate .t./.f. to that, but it's not very hard to do so.

Moving focus is easier with a checkbox, as it is a single control, while an optiongroup each option can have focus, so perhaps for that reason I'd also choose a checkbox, although it's easy to move focus anyway, by calling the Setfocus() method of whatever control you want to get focus next. Or by returning a number N from a valid() event to move N controls further. Or by Keyboard '{Tab}' to emulate a Tab key for moving focus.

Bye, Olaf.
