checkbox让checkboxlist全选的问题
在.net里面有没什么好的方法???好象要JS才能实现,能给个完全的JS代码吗?急急急...有.net方法最好 --------------------编程问答-------------------- 在 Checkbox 点击事件里写个循环，把Checkboxlist 里的每一个都Check一次就OK了 --------------------编程问答-------------------- http://www.cnblogs.com/lovecherry/archive/2005/05/15/155835.html其实代码你可以自己搜索得到，懒惰啊懒惰 --------------------编程问答-------------------- <script>
function SelectAll(objID){
var checkBoxList = document.getElementById(objID);
for(var i = 0 ;i<checkBoxList.length;i++){
checkBoxList[i].checked = true;
}
}
</script> --------------------编程问答-------------------- 好象要JS才能实现?
用后台代码更容易
foreach(ListItem i in checkboxlist.items)
i.Selected = true; --------------------编程问答-------------------- try these codes as below:

--------------------编程问答-------------------- 07年的帖子LZ早是牛人了吧
public partial class CheckedAll : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
foreach (ListItem item in this.CheckBoxList1.Items)
{
item.Selected=true;
}
}
}

哈哈~~ 才发现时07年的
补充：.NET技术 , ASP.NET
