OnFormat Property

Sets or returns the value of the On Format box in the Properties window of a report section. Read/write String.

expression.OnFormat

expression Required. An expression that returns one of the objects in the Applies To list.

Remarks

This property is helpful for programmatically changing the action Microsoft Access takes when an event is triggered. For example, between event calls you may want to change an expression's parameters, or switch from an event procedure to an expression or macro, depending on the circumstances under which the event was triggered.

The Format event occurs when Microsoft Access determines which data belongs in a report section, but before Access formats the section for previewing or printing.

The OnFormat value will be one of the following, depending on the selection chosen in the Choose Builder window (accessed by clicking the Build button next to the On Format box in the report section's Properties window):

If Expression Builder is chosen, the value will be "=expression", where expression is the expression from the Expression Builder window.
If Macro Builder is chosen, the value is the name of the macro.
If Code Builder is chosen, the value will be "[Event Procedure]".

If the On Format box is blank, the property value is an empty string.

Example

The following example prints the value of the OnFormat property in the Immediate window for the "GroupHeader0" section in the "Purchase Order" report.

Debug.Print Reports("Purchase Order").Section("GroupHeader0").OnFormat
