{CONDITION}

Syntax

{CONDITION= (expression )} ... {REGION= Label } ... {ENDREGION}

Arguments

Expression: Character. A logical variable or expression that evaluates to .T. (TRUE) or .F. (FALSE).
Label: Character. A unique label for the region that the condition applies to.

Description

The {CONDITION} command allows the display of Xdialog elements to be turned on or off, depending on how a logical expression is evaluated.

payby = 1
ui_dlg_box("Title",<<%dlg%
{region=a}
Name:|[.40name];
{endregion};
{region}
Paid by: (payby={Cash,Check,Credit Card});
{endregion};
{condition=(payby=3)}
{region=a}
Credit Card Number: |[.40number];
{endregion};
{condition=.t.}
{region=a}
Ship Via: |[.40ship_via];
{endregion}
%dlg%)

This script produces this dialog when the condition is FALSE:

And, it produces this dialog when the condition is TRUE:

As you can see, when the condition is .F. (FALSE), the space that would have been taken up by the Credit Card Number controls is still taken up.
