输入'12'，点击按钮，a为假，b为真...注意EnableClientScript设置为假。

<asp:TextBox ID="TextBox1" runat="server"
     Width="20px" MaxLength="3"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1"
     runat="server" EnableClientScript="false" ControlToValidate="TextBox1"
     ErrorMessage="RegularExpressionValidator"
     ValidationExpression="([1-9]|[1-9][0-9]|[1-9][0-9][0-9])"
     ForeColor="Red"><sup>invalid</sup></asp:RegularExpressionValidator>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

protected void Button1_Click(object sender, EventArgs e)
{
  Page.Validate();
  bool a = RegularExpressionValidator1.IsValid;
  bool b = System.Text.RegularExpressions.Regex.IsMatch(TextBox1.Text,
             RegularExpressionValidator1.ValidationExpression);
}

替换ValidationExpression为：

ValidationExpression="^([1-9]|[1-9][0-9]|[1-9][0-9][0-9])$"
