INTRODUCTION
ASP.NET validator are controls used for validating the data entered in an input control , such as the textbox of a Web page.When a user enters invalid data in an associated control, the ASP.NET validator control displays an error message on the screen. The error message is defined as a property value of the validation control . The data being entered is validated each time it is entered by the user , and the error message disappears only when the data is valid. Validation controls help save time and enhance the efficiency of the application by validating the data before a request is sent to the server.
The System.Web.UI.WebControls.BaseValidator class provides basic implementation required for all validation controls.
Public Properties of the BaseValidator Class
ControlToValidate : Handles an input control, such as the TextBox Control , which needs to be validated.
Display : Handles the behavior of the error message in a validation control.
EnableClientScript : Handles a value indicating whether or not client-side validation is enabled
Enabled : Handles a value that indicates whether or not the validation control is enabled or not.
ErrorMessage : Handles the text for the error message displayed in a ValidationSummary control when validation fails.
ForeColor : Handles the color of the messgage displayed when validation fails.
IsValid : Handles a value that indicates if the focus is set on the control or not , specified by the ControlToValidate property when validation fails.
Text : Handles the text displayed in the validation control when the validation fails.
ValidationGroup : Handles the name of the validation group to which this validation control belongs.
Note: ValidationGroup property , when set, validates only the validation controls within the specified group when the control is posted back to the server.
Public Methods of the BaseValidator Class
validate() : Helps in performing validation on the associated input control and update the IsValid property
GetValidationProperty : Help in determining the validation property of a control , if it exists.
The following ASP.NET validator controls are
