复选框服务器控件OnCheckedChanged [英] checkbox Server Control OnCheckedChanged

问题描述

您好，我有这段代码，它可以与输入复选框html contol完美运行

hello , i have this code and it run perfectly with input checkbox html contol

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<script  language="javascript" type="text/javascript" >
              function chvisible(controlId)
                {
                    var control = document.getElementById(controlId);
                    if(control.style.display == "none" || control.style.display == "")
                        control.style.display = "block";
                        control.body.text="";
                    else
                        control.style.display = "none";
                }
</script>
        <asp:TextBox ID="TextBox1" runat="server" Style="display: none"></asp:TextBox>
        <input id="Checkbox1" type="checkbox" onclick="chvisible(''<%=TextBox1.ClientID %>'');"/>
</asp:Content>

当我更改< input>到CheckBox
我将写什么而不是"chvisible(''<%=TextBox1.ClientID %>'');"
在onCheckedChanged事件中?????

复选框服务器端控件没有onclick事件

当我尝试在下面编写此代码时，它不会运行

when i change the <input > to CheckBox
what i will write instead of "chvisible(''<%=TextBox1.ClientID %>'');"
in onCheckedChanged Event ?????

checkbox server side control doesn''t have onclick event

when i try to write this following , it don''t run

<asp:CheckBox ID="CheckBox2" runat="server" OnCheckedChanged="chvisible(''<%=TextBox1.ClientID %>'');" />

如果我写
也失败了

also it failed if i write

<asp:CheckBox ID="CheckBox1" runat="server" onclick="chvisible(''<%=TextBox1.ClientID %>'');" Text="sport" />

推荐答案

这样的更改-

change like this--

<asp:checkbox id="CheckBox2" runat="server" xmlns:asp="#unknown" />

现在在codebehind
的form_load中

now in form_load in codebehind

CheckBox2.InputAttribute.Add("onchange","chvisible(''" +TextBox1.ClientID + "'');")

--Pankaj

--Pankaj

复选框服务器端控件没有onclick事件

您可以将onclick事件添加为

checkbox server side control doesn''t have onclick event

You can add the onclick event as

CheckBox2.InputAttribute.Add("onclick","chvisible(''" +TextBox1.ClientID + "'');")
