Sets whether the format that is specified in the Style Property is applied to text in a field. For fields in a CueGroup control, this property is used to configure the color of the color indicator on the cue.
This note pertains to backward compatibility only. If the property is set to Boolean true or false, it sets whether the format specified in the Style property is applied to text in a field.
Page field controls that are not of data type Boolean or BLOB.
Field controls in CueGroups of data type Boolean, Text, or Codeunit.
The information in this topic is mainly applicable to formatting the text of page fields. For information about how to use the StyleExpr property for configuring Cues, see How to: Set Up Colored Indicators on Cues by Using the Style and StyleExpr Property.
You can set StyleExpr to either the name of a variable; a text constant in apostrophes, for example, 'strong'; or, for backward compatibility, to true or false. StyleExpr must not be set to a Text or Boolean array; it will compile, but fail at runtime.
If the StyleExpr property evaluates to true, then the value of the field is formatted as specified by the Style Property. You can set the value to true or false, or you can use a variable that evaluates to true or false. The property's default value is false.
You can use a conditional setting of styles by inserting the conditional code in, for example, the OnAfterGetRecord Trigger. Remember to cover all cases in else branches to avoid incorrect styles. For example:
if (MyField = 'abc') then MyStyleVar := 'Ambiguous' else MyStyleVar := 'Favorable'
To use a variable for the StyleExpr property, the IncludeInDataSet Property of the variable must be set to Yes.
