( # Start of group
(?=.*\d) # must contains one digit from 0-9
(?=.*[a-z]) # must contains one lowercase characters
(?=.*[A-Z]) # must contains one uppercase characters
(?=.*[@#$%]) # must contains one special symbols in the list "@#$%"
. # match anything with previous condition checking
{6,20} # length at least 6 characters and maximum of 20
) # End of group

RegExp : ((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{6,20})

Hi,
You are basically asking about strong password field for the user.So here is the solution you can use regular expression validation and you can pass this expression as per your requirement.

^.*(?=.{10,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$

ASP.NET

<pre><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" 
            ErrorMessage="Please enter a strong passord with min of 10 charecter" ControlToValidate="TextBox1" 
            ValidationExpression="^.*(?=.{10,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&amp;+=]).*$"></asp:RegularExpressionValidator>
            
        <asp:Button ID="Button1" runat="server" Text="Button" />
