Required Field Validator control is used to make an input control as a mandatory field or the input field should not be empty.

The other validation controls do not validate for an empty field. For example, you can specify that users must fill password in a password Text Box before submit the login form.

Sometimes browsers (mobile browsers) do not support javascript.

Controls such as the Data Grid View automatically detect this interface and provide error icons along with descriptions about the error.These controls prevent users from submitting the wrong type of data.There are six validation controls available in the ASP. By default, the validation controls perform validation on both the client (the browser) and the server.After that, create a folder under the root application for storing the uploaded images.Validation controls are very useful while submitting data into a database table.
