ASPxListBox.Value Property

Gets or sets the editor’s value.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v19.2.dll

Declaration

C#

public override object Value { get; set; }

VB.NET

Public Overrides Property Value As Object

Property Value

Type	Description
Object	A Object value representing the editor’s value.

Remarks

This property overrides the base ASPxEdit.Value property to implement a proper display of editor items when the property’s value changes.

The Value property can be used to manipulate the editor’s value.

If you need to validate the editor’s value before posting it, you can handle either client-side ASPxClientEdit.Validate or server-side ASPxEdit.Validate events, or both. If no validation is performed and the value posted is not correct, then an exception is raised.
