ListViewFilterAttribute(String, String) Constructor

Creates an instance of the ListViewFilterAttribute class and initializes its properties.

Namespace: DevExpress.ExpressApp.SystemModule

Assembly: DevExpress.ExpressApp.v24.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public ListViewFilterAttribute(
    string id,
    string criteria
)

VB.NET

Public Sub New(
    id As String,
    criteria As String
)

Parameters

Name	Type	Description
id	String	A string value that represents the ID of the filter to be created. This parameter value is assigned to the ListViewFilterAttribute.Id property.
criteria	String	A string value that represents criteria for filtering the current List View. This parameter value is assigned to the ListViewFilterAttribute.Criteria property.

Remarks

If you apply several ListViewFilter attributes, you can specify an index for each of them. This allows you to locate the Filter Action’s items in the required order.

The following code demonstrate how to pass an index:

C#

[ListViewFilter("Filter2","",Index=2)]
public class Contact : Person {
   //...
}

VB.NET

<ListViewFilter("Filter2","",Index:=2)> _
Public Class Contact
      Inherits Person
   '...
End Class
