Remarks

Individual filter expressions (for example, expressions that contain advanced or custom functions) cannot be converted to Filter Editor nodes. Below is an example:

[Sales Date] > AddDays(LocalDateTimeToday(), -25)

The AllowCustomExpressions property specifies whether and how the Filter Editor displays these expressions. The following options are available:

True

The Filter Editor displays custom expressions, and allows users to edit existing and create new custom expressions.

Users can create new custom expressions from a context menu.

Users can click the expression to open the Expression Editor, which allows them to edit the expression.

Handle the ColumnView.FilterExpressionEditorCreated event to customize this Expression Editor.

Default

The Filter Editor displays custom expressions as simple text. A user cannot edit or create custom expressions.

False

The Filter Editor does not display custom expressions, and does not allow users to create new ones.
