Why you shouldn't gray out disabled buttons?

Gray is often used to communicate a low priority button (e.g., cancel buttons). When they see a gray button, they won't know for sure if it's disabled unless they click it. This uncertainty and unpredictability is not an optimal user experience. When making your button transparent, adjust the opacity, not the color.

How do you prevent a button from validating its form?

To prevent validation from being performed, set the CausesValidation property to false . You should set the CausesValidation property to false when you are using the PostBackUrl property to post back to a different page.

How do I enable a button when a form is valid?

Use the disabled=”@(! context. Validate()) attribute for the submit button component to validate the form to display and enable or disable the button. If an Error message occurs in form validation, the button is disabled.

How would you ensure that the button code will disable the submit button if the form is invalid?

If the textbox control value is invalid, we also want to disable the submit button so that the user cannot submit the form. We are using the “ng-disabled” property for the control to do this based on the conditional value of the “$dirty” and “$invalid” property of the control.
