System.Web.UI.WebControls Namespace   LinkButton Class

---

Sets or retrieves a value indicating whether validation is performed when the LinkButton control is clicked.

Inline	<asp:linkbutton causesvalidation [ = true | false ] ... >
Script	LinkButton.CausesValidation [ = true | false ]

This property accepts or returns only a boolean value: true if validation is performed when the link button is clicked; otherwise, false. Default value is true.

By default, page validation is performed when a LinkButton 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 a LinkButton 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 to prevent page validation from occurring when a Cancel or Reset linkbutton is clicked.

<asp:linkbutton commandname = "update" runat = "server"
   text = "Update" />
<asp:linkbutton commandname = "cancel" runat = "server"
   text = "Cancel" causesvalidation=false />
