對你的答案給予一些解釋。 – Tirth 2013-11-07 05:10:49

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtPhonenumber" ErrorMessage="Only Numbers" Display="None" ValidationExpression="^\d+$" ></asp:RegularExpressionValidator>

ValidationExpression = 「^ \ d + $」時使用此數字格式驗證
