    ColumnBase column
)

    column As ColumnBase
)

Parameters

Name	Type	Description
column	ColumnBase	A ColumnBase descendant that specifies the unbound column.

Remarks

Data for unbound columns can be provided within the GridControl.CustomUnboundColumnData event handler, or by specifying an expression via the ColumnBase.UnboundExpression property. At runtime, an end-user can edit expressions for unbound columns using the Expression Editor.

End-users can invoke this editor using a column's context menu if the ColumnBase.AllowUnboundExpressionEditor option is enabled. To show the Expression Editor in code, use the ShowUnboundExpressionEditor method.

The DataViewBase.UnboundExpressionEditorCreated event fires in response to creating the Expression Editor, allowing you to prevent the editor from being displayed, customize its settings, etc.
