ValidationSummary.EnableClientScript Property

Gets or sets a value indicating whether the ValidationSummary control updates itself using client-side script.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[ThemeableAttribute(false)]
public bool EnableClientScript { get; set; }
<asp:ValidationSummary EnableClientScript="True|False" />

Property Value

Type: System.Boolean
true if the ValidationSummary control updates itself using client-side script; otherwise, false. The default is true.

Use this property to specify whether the ValidationSummary control updates itself using client-side script. When this property is set to true, client-side script is rendered on the client to update the ValidationSummary control, if the browser supports that feature. When this property is set to false, no client-side script is rendered on the client and the ValidationSummary control only updates itself on round trips to the server. In this situation, the ShowMessageBox property has no effect.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.

The following code example demonstrates how to use the EnableClientScript property to prevent the ValidationSummary control from using client-side script to update itself.


<asp:ValidationSummary 
     id="valSum" 
     DisplayMode="BulletList"
     EnableClientScript="false"
     ShowMessageBox="false"
     ShowSummary="true" 
     HeaderText="You must enter a value in the following fields:"
     Font-Names="verdana" 
     Font-Size="12"
     runat="server"/>
