Class: TRequiredListValidator

TRequiredListValidator checks the number of selection and their values for a TListControl that allows multiple selection. This validator will only work for the components with the name attribute ending with "[]".

You can specify the minimum or maximum (or both) number of selections required using the <tt>MinSelection</tt> and <tt>MaxSelection</tt> properties, respectively. In addition, you can specify a comma separated list of required selected values via the <tt>RequiredSelections</tt> property.
