推荐答案

步骤:
1.在按钮单击事件方法中，遍历数据列表项
2.使用FindControl来访问所需的标签
3.根据需要设置可见性.

试试类似的东西:

Steps:
1. In button click event method, loop through datalist items
2. Use FindControl to get access to the label you need
3. Set the visibility as per your need.

Try something like:

foreach (DataListItem item in myDataList.Items)
{
    Label myTempLabel = (Label)item.FindControl("myLabel");   
    
    // Do what you need to with this label
    myTempLabel.Visible = false; 
}

试试吧！

Try!
