C#webfrom six verification and use method

C # contains six types of authentication methods, namely:

One, non-null verification requiredfieldvalidator.

Second, comparative verification CompareValidator.

Third, scope verification RangeValidator.

Four, the regular expression validation RegularExpressionValidator.

V. Verification summary ValidationSummary.

Vi. custom Validation.

Two application tips:

1. Prevent the button from firing the validation control.
By default, the Class 3 button fires validation.
If you do not want to fire validation: give the button a causevalidation=false

2. Verify the problem with the grouping.
Set the ValidationGroup property of the input control (text box, radio, multiple selection), validation control (non-null, contrast, range, regular, custom, summary), button to the same value.

They become a group.

The first three attributes that need to be modified to use the validation space (six general authentication methods are common):

1.ErrorMessage: Error message displayed for validation failure

2.Display: How the Validator is displayed-in general dynamic display (verification failure display).

3.CotrolToValidate: The control ID to validate (for example: Verify the contents of the account in the TextBox, cotorltovalidate the textbox ID).
