you are setting wrong expresssion see attached file, add it to any web project and run yourself

Nilesh Shah · Answer

you need a regex something like: "(^1300\d{6}$)|(^1800\d{6}$)" where: ^ indicates start of input, 1300 or 1800 is the pattern to match, d{6} indicates 6 digits change it as you want. See below sample web form in aso.net form id = "form1" runat = "server" > div > asp:TextBox id = "TextBox1" runat = "server" /> asp:RegularExpressionValidator id = "RegularExpressionValidator1" ControlToValidate = "TextBox1" ValidationExpression = "(^1300\d{6}$)|(^1800\d{6}$)" Display = "Static" ErrorMessage = "Error" EnableClientScript = "False" runat = "server" /> asp:Button ID = "Button1" text = "Validate" runat = "server" /> div > form >

hi, if i give like this means it is not taking [RegularExpression("(^1300\d{6}$)|(^1800\d{6}$)", ErrorMessage = "Entered number must be start with 1300 or 1800")]

Textbox should accept starting number 1300 or 1800 only. otherwise it will display error this is my requirement
