Namespace: DevExpress.Xpf.Grid

Declaration

public bool AllowUnboundExpressionEditor { get; set; }

VB.NET

<XtraSerializableProperty>
Public Property AllowUnboundExpressionEditor As Boolean

Property Value

Type	Description
Boolean	true if an end-user can open the Expression Editor for the current unbound column, using a context menu; otherwise, false.

Remarks

Unbound columns can be populated with data by specifying an expression via the ColumnBase.UnboundExpression property. If the AllowUnboundExpressionEditor option is enabled, a new menu item (Expression Editor...) is added to the column's context menu. An end-user can select this menu item to open the Expression Editor and edit the column's expression.

If the AllowUnboundExpressionEditor option is disabled, the Expression Editor can be opened in code using the DataViewBase.ShowUnboundExpressionEditor method.
