TRequiredFieldValidator ensures that the user enters some data in the specified input field. By default, TRequiredFieldValidator will check if the user input is empty or not. The validation fails if the input is empty. By setting <tt>InitialValue</tt>, the validator can check if the user input is different from <tt>InitialValue</tt>. If not, the validation fails.

<h2>TRangeValidator</h2>
<p>
TRangeValidator verifies whether an input value is within a specified range. TRangeValidator uses three key properties to perform its validation. The <tt>MinValue</tt> and <tt>MaxValue</tt> properties specify the minimum and maximum values of the valid range. The <tt>DataType</tt> property specifies the data type of the value being validated. The value will be first converted into the specified type and then compare with the valid range. The data types that can be checked against are the same as those in TCompareValidator.
