Gets or sets a value indicating whether client-side validation is enabled.

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

[<ThemeableAttribute(false)>]
member EnableClientScript : bool with get, set

Property Value

Type: System.Boolean

true if client-side validation is enabled; otherwise, false. The default value is true.

Use the EnableClientScript property to specify whether client-side validation is enabled.

Validation controls always perform validation on the server. They also have complete client-side implementation that allows DHTML-supported browsers (such as Microsoft Internet Explorer 4.0 and later) to perform validation on the client. Client-side validation enhances the validation process by checking user input before it is sent to the server. This allows errors to be detected on the client before the form is submitted, avoiding the round trip of information necessary for server-side validation.

By default, this value is set to true, which enables client-side validation if the browser supports it. You can disable client-side validation on a control-by-control basis. This is useful if dynamic updating on the client creates problems with the layout of the page, or if you want to execute some server code before validation takes place.

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 disable client-side validation so that the random numbers can be generated on the server.

System_CAPS_security Security Note

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
