Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v18.2.dll

Declaration

C#

public string FilterExpression { get; protected set; }

VB.NET

Public Property FilterExpression As String

Property Value

Type	Description
String	A string value representing the applied filter criteria. An empty string, if no filtering is used.

Remarks

When implementing a method delegate of the GridViewCustomBindingGetUniqueHeaderFilterValuesHandler type, the FilterExpression property gets the GridView’s currently applied filter conditions that do not contain a filter criterion applied to the processed column specified by the GridViewCustomBindingGetUniqueHeaderFilterValuesArgs.FieldName property.
