Purpose

Define a text that is shown for empty values.

Class

bDataColumn

Type

Access / Assign

Data Type

String

Description

The bBrowser uses this access when drawing the column values if empty values shall not be shown and a column value is an empty value. It can be defined with the access, which text is shown instead of the empty value. As default a NULL_STRING is shown.

 

With the access bDataColumn:SuspendEmptyValues it can define, whether empty values are shown.

 

So that changes that were made with this access are also shown in the browser, the column data must be re-read with the method bBrowser:Refresh().

Samples

The following sample defines that for empty values the text "<NULL>" is shown.

 

oColumn := oBrowser:GetColumn(#NAME)

IF !EMPTY(oColumn)

 oColumn:SuspendEmptyValues := TRUE

 oColumn:ViewEmptyValuesAs := "<NULL>"

 oBrowser:Refresh()

 oBrowser:Redraw()

ENDIF
