Are we talking ASP .NET bere ? if yes, there are two ways of doing it

1. Using JavaScript to call a function (See solution 1)

2. Using Regular Expressions Validation

ASP

<asp:regularexpressionvalidator id="valPassword" runat="server" xmlns:asp="#unknown">
   ControlToValidate="txtPassword"
   ErrorMessage="Minimum password length is 5"
   ValidationExpression=".{5}.*" /</asp:regularexpressionvalidator>
