   </asp:DataList>

推荐答案

借助DataList和Repeater，模板中的按钮将其事件发送到容器的ItemCommand事件.您已经设置了

With DataList and Repeater, the buttons within the template send their events to the container''s ItemCommand event. You have already set up

commandname="save"

，因此在后面的代码中，需要

so in your code behind you need

protected void DataList2_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "save")
        {
            // your code for saving
        }
    }
