What is compare validator in ASP.NET in English and Hindi
Compare validator in ASP.NET in English
The CompareValidator control is an ASP.NET validation control that checks if the value entered in an input field matches another value or a control on the same page. It can be used to validate fields such as passwords, email addresses, and confirmation fields.
Here's an example of how to use the CompareValidator control to validate that the value entered in a password field matches the value entered in a confirmation field:
In this example, the Password TextBox and ConfirmPasswordTextBox are two text boxes used for entering a password and a confirmation password, respectively. The Password Required Field Validator is a required field validator that ensures that the user enters a value in the password field. The Password Compare Validator is a compare validator that checks if the value entered in the Confirm Password TextBox matches the value entered in the PasswordTextBox.
When the user submits the form, the CompareValidator control will check if the value entered in the ConfirmPasswordTextBox matches the value entered in the Password TextBox. If the values do not match, an error message will be displayed.
Note that the ControlToCompare property of the CompareValidator control specifies the ID of the control to compare against. In this case, it is set to the ID of the PasswordTextBox control. The ErrorMessage property specifies the error message to display if the validation fails.
