Explain in simple steps how to use validation controls?-tech17032012

1.Draw a validation control on a Web form and set its ControlToValidate property to the control you want to validate. 2.If you’re using the CompareValidator control, you also need to specify the ControlToCompare property. 3.Set the validation control’s ErrorMessage property to the error message you want displayed if the control’s data is not valid. 4.Set the validation control’s Text property if you want the validation control to display a message other than the message in the ErrorMessage property when an error occurs. Setting the Text property lets you briefly indicate where the error occurred on the form and display the longer ErrorMessage property in a ValidationSummary control. 5.Draw a ValidationSummary control on the Web form to display the error messages from the validation controls in one place. 6.Provide a control that triggers a postback event. Although validation occurs on the client side, validation doesn’t start until a postback is requested.
