how to do allow only phone number validation max 10

Hi,

MaxLength="10">

"^[0-9]{10}$">

<asp:TextBox runat="server" ID="txtPhone" MaxLength="12">asp:TextBox>

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"

ErrorMessage="Error" ForeColor="Red" ControlToValidate="txt"

ValidationExpression="^[0-9]{12}$">asp:RegularExpressionValidator>

Hey !

you can use Regular Expression Validator for that too :

ErrorMessage="Error" ForeColor="Red" ControlToValidate="txt"
ValidationExpression="^[0-9]{12}$">
