On both the client and server side you can create a custom response, such as a color change in a control or a font change for text on a label. To display custom validation messages In the Page_Load event handler, call the Validate method of the validation control or of the page. Check the IsValid property of the validation control or page and conditionally add text or a control, or change the properties (for example, color) of a control. The following code example displays the text "All entries are valid" when the IsValid property is true, and the text "There are one or more invalid entries" when the property is false. C#VB Copy if (this.IsPostBack) { ValidationControl1.Validate(); if (ValidationControl1.IsValid) { lblOutput.Text = "All entries are valid."; } else { lblOutput.Text = "There are one or more invalid entries."; } } See Also Tasks How to: Control Validation Error Message Display for ASP.NET Server Controls How to: Format Validation Error Messages for ASP.NET Server Controls Concepts Types of Validation for ASP.NET Server Controls Client-Side Validation for ASP.N
