TreeList - Unbound Expression Editor

This will invoke the Unbound Expression Editor dialog, with which end-users can modify an expression used to calculate cell values for this column. The UnboundColumnExpressionEditorMode property specifies the type of this dialog.

  • AutoComplete

    The new expression editor that supports auto-completion and syntax highlighting.

    expression-editor-intellisense-overview

  • Standard

    The legacy expression editor dialog type.

    ExpressionEditor

  • Default

    If the WindowsFormsSettings.DefaultSettingsCompatibilityMode property equals Latest, the new AutoComplete expression editor will be used. Otherwise, if this property is set to v16, the legacy dialog will be invoked instead.

The UnboundColumnExpressionEditorMode property affects the dialog your end-users utilize. However, you will always work with the legacy dialog at design time.

See the Expression Editor article to learn about all differences between the expression editor types.
