Gets or sets a value indicating whether validation is performed when the HtmlInputButton control is clicked.

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

abstract CausesValidation : bool with get, set 
override CausesValidation : bool with get, set

Property Value

Type: System.Boolean
true if validation is performed when the HtmlInputButton control is clicked; otherwise, false. The default value is true.

By default, page validation is performed when an HtmlInputButton control is clicked. Page validation determines whether the input controls associated with a validation control on the page all pass the validation rules specified by the validation control.

You can specify or determine whether validation is performed on both the client and the server when an HtmlInputButton control is clicked by using the CausesValidation property. To prevent validation from being performed, set the CausesValidation property to false.

This property is commonly used in the event handler for the ServerClick event to prevent page validation from occurring when a Cancel or Reset button is clicked.

The following code example demonstrates how to use the CausesValidation property to prevent page validation from occurring. Notice how the Validate method activates each validation control independently.

No code example is currently available or this language may not be supported.
