推荐答案

Html：

Html:

<div>
        <asp:TextBox ID="txtName" runat="server"></asp:TextBox> <asp:TextBox ID="txtAddress" runat="server"></asp:TextBox> <asp:CheckBox ID="chkIsMarried"

            runat="server" /> <asp:TextBox ID="txtSpouse" runat="server"></asp:TextBox><asp:Button

                ID="Button1" runat="server" Text="Button"  OnClientClick="return  validate();" />
    </div>



Javascript:

 <script type="text/javascript">
        function validate() {
           
            debugger;
            var name, address, isMarried, spouse;
            name = document.getElementById("txtName").value;
            address = document.getElementById("txtAddress").value;
            isMarried = document.getElementById("chkIsMarried").checked;
            spouse = document.getElementById("txtSpouse").value;

            if (name == "") {
                alert("Name requered");
                document.getElementById("txtName").focus();
                return false;

            }
            else if (address == "") {
                alert("Address requered");
                document.getElementById("txtAddress").focus();
                return false;

            }

            else if (isMarried==true) {
                if (spouse == "") {
                    alert("Spouse name requered when you are married");
                    document.getElementById("txtSpouse").focus();
                    return false;
            }
               

            }


        }

    </script>

你可以使用服务器端和客户端：



服务器端：禁用加载功能中的所有验证，并在检查复选框控件并启用它时启用它按钮点击



客户端：相同但使用javascript



HTML：

you can use server side and client side:

server side: disabled all validation in load function and enabled it when check the checkbox control and validate it by button click

client side : same but using javascript

HTML:

<asp:textbox id="txtName" runat="server" xmlns:asp="#unknown" /> 
<asp:requiredfieldvalidator id="RequiredFieldValidator4" runat="server" controltovalidate="txtName" display="None" errormessage="Please enter name">
ValidationGroup="info" 
<asp:checkbox id="chkMarried" runat="server" onchange="enableddisabled(this);" />
<asp:button id="btnSubmit" runat="server" validationgroup="info"/>

and use ValidatorEnabled function to enable and disable the validation control  in javascript

ValidatorEnabled(validationcontrolname,boolean);

为了使用自定义验证器，您需要一个RequiredFieldValidator来进行相同的控制。 />
将RequiredFieldValidator放入文本框（txtspousename）并尝试。



希望它会f是你的Serverside活动。



此解决方案解决了我的问题

Inorder to use Custom validator, you need a RequiredFieldValidator for same control.
Put the RequiredFieldValidator for your textbox(txtspousename) and try.

Hope it will fire your Serverside event.
