我有以下几层瓦希德器。 其目的是限制1900年至2070年的数值。 然而,当我进入字母顺序时,它就造成了错误。 我只想向用户输入惯用的值。 我如何克服这一问题? 请帮助。

                        <asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtYear"
                            ValidationGroup="report" ErrorMessage="EM1|Year" MaximumValue="2079" MinimumValue="1900"
                            SetFocusOnError="True" Display="Dynamic" Type="Integer">
                                            <img src="../../Images/error.gif" alt="Format" />
                        </asp:RangeValidator>

You can use custom validator in this case. It may look like this

将这一条作为你的有效载体编码

  <asp:customvalidator ID="Customvalidator1" ControlToValidate="txtYear" runat="server"
             EnableClientScript="true"
             errormessage="CustomValidator" 
        onservervalidate="Customvalidator1_ServerValidate"></asp:customvalidator>

在您的法典中加以使用:

受保护的无效习俗验证器1

    {

        int result;

        if (int.TryParse(txtYear.Text,out result))
        {
            if (1900 <= result && result <= 2079)
                args.IsValid = true;
            else
                args.IsValid = false;
        }

        args.IsValid = true;
    }
