ASPxButton.CausesValidation Property

Gets or sets a value indicating whether validation (client and server) is performed when the button is clicked.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v18.2.dll


public virtual bool CausesValidation { get; set; }
Public Overridable Property CausesValidation As Boolean

Property Value

Type Default Description


true if validation is performed when the button is clicked; otherwise, false.


If the CausesValidation property is set to true (the default value), then a button click forces validation of an editor group, specified via the ASPxButton.ValidationGroup property.

The button's properties can be used to specify a container for whose controls the button causes validation (ASPxButton.ValidationContainerID), and whether invisible editors should be validated together with visible ones (ASPxButton.ValidateInvisibleEditors).


You should set the CausesValidation property to false when you are using the ASPxButton.PostBackUrl property to post back to a different page. You should explicitly check validation when posting back to a different page.


The complete sample project is available in the DevExpress Code Central database at E557.

         <dxe:ASPxButton ID="ASPxButton1" runat="server" AutoPostBack="False" 
         Text="ASPxButton" CausesValidation="False">
