Parameters
| Name | Type | Description |
|---|---|---|
| column | GridColumn | A GridColumn that represents an unbound column whose expression will be edited in the Expression Editor. |
Remarks
Data for unbound columns can be provided by specifying an expression via the GridColumn.UnboundExpression property. At runtime, an end-user can edit expressions for unbound columns via an Expression Editor - specially designed modal form. This editor can be opened:
- via a context menu, if the GridColumn.ShowUnboundExpressionMenu option is enabled;
- by calling the ShowUnboundExpressionEditor method.
The ColumnView.UnboundExpressionEditorCreated event fires in response to creating the Expression Editor. You can handle this event to prevent the editor from being displayed in specific instances, change the editor form’s settings, etc.
