ASPxFilterControlBase.AllowNonVisualFilterExpression Property

Specifies whether the filter control enables filtering using complex valid expressions that cannot be visualized in the Visual tab.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v20.2.dll


public bool AllowNonVisualFilterExpression { get; set; }
Public Property AllowNonVisualFilterExpression As Boolean

Property Value

Type Default Description


true, if the expressions that cannot be visualized can be used; otherwise, false. The default is false.


When the ASPxFilterControlBase.ViewMode property is set to VisualAndText, complex valid expressions typed as text (via the Text tab) fail validation if they can not be visualized as a tree in the Visual tab.

We recommend that you set this property to true only if your scenario requires using a valid expression that cannot be visualized in the Visual tab.
