Invokes an Expression Editor that enables editing an expression for the specified unbound column.
public virtual void ShowUnboundExpressionEditor( RowProperties properties )
Public Overridable Sub ShowUnboundExpressionEditor( properties As RowProperties )
A RowProperties object that identifies the row for which the Expression Editor should be created.
Data for unbound columns can be provided by specifying an expression via the RowProperties.UnboundExpression property. At runtime, an end-user can edit expressions for unbound columns via an Expression Editor, which is a specially designed modal form. This editor can be opened:
- via a context menu, if the RowProperties.ShowUnboundExpressionMenu option is enabled;
- by calling the ShowUnboundExpressionEditor method.
The VGridControl.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, or to change the editor form's settings, etc.
