推荐答案

• 事件绑定到一个按钮，


• 迭代线槽项目的<$ C $财产C>的CheckBoxList


• 按选属性设置文本值>列表项

• bind an event to a button,
• iterate trough the Items property of the CheckBoxList
• set the text value according to the selected property of the listitem

这样的：

protected void button_Click(object sender, EventArgs e)
{
    foreach (ListItem item in theCheckBoxList.Items)
    {
        item.Text = item.Selected ? "Checked" : "UnChecked";
    }
}





添加一个值，你可以这样做：

to add a value you could do:

 foreach (ListItem item in theCheckBoxList.Items)
 {
        item.Text = item.Selected ? item.Value  : "";
 }

或显示在微型报告人的值：

or display al values in a mini-report:

    string test = "you've selected :";
    foreach (ListItem item in theCheckBoxList.Items)
    {
        test += item.Selected ? item.Value + ", " : "";
    }
    labelResult.Text = test;
