C# CheckBoxList 实现全选/反选功能怎么写？

首先我们用RadioButtonList控件，且必须包含OnSelectedIndexChanged事件和AutoPostBack=‘true’属性，

<asp:LinkButton  　runat="server" Text="全选"  onclick=btn1_click></asp:LinkButton>

<asp:LinkButton  runat="server" Text="反选" onclick=btn2_click ></asp:LinkButton> 

然后在OnSelectedIndexChanged事件里写如下代码：

public void btn1_Click()
{
if (checkboxlistName.Items[0].Selected == true)
            {
                for (int i = 0; i < checkboxlistName.Items.Count; i++)
                {
                    checkboxlistName.Items[i].Selected = true;
                }
            }
            else
            {
                for (int i = 0; i < checkboxlistName.Items.Count; i++)
                {
                    checkboxlistName.Items[i].Selected = false;
                }
            }
}
puclic void btn2_Click()
{
        for (int i = 0; i < checkboxlistName.Items.Count; i++)
                {
                    checkboxlistName.Items[i].Selected = !checkboxlistName.Items[i].Selected;
                }
}

ok，完成！
