                            </asp:Repeater>怎样在后台取Repeater中红色标签SPAN中绑定的数据，不是用js取，是用C#代码取，也不要用Repeater的什么事件取值，换别的，我是要自写的方法调用的

Answer 1

搞Web开发，首先要把通讯机制搞清楚。什么C#取，JS取，完全还没有概念。

Answer 2

意思就是说不要用JS：javascript取值！

Answer 3

使用label,literal显示数据
findcontrol

Answer 4

算了，谁知道在Repeater的ItemDataBound事件中取Repeater中的SPAN标签中内容什么取？ if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
           HtmlGenericControl id = e.Item.FindControl("RI") as HtmlGenericControl; 
            HiddenFieldID.Value = id;
        }红色地方报错：Cannot implicitly convert type 'System.Web.UI.HtmlControls.HtmlGenericControl' to 'string' 我把它改为“string id = e.Item.FindControl("RI").ToString();”结果运行后id的值为
“System.Web.UI.HtmlControls.HtmlGenericControl”请问这是什么回事？

Answer 5

你也可以用action来提交 也就是表单提交

Answer 6

 HtmlContainerControl span = e.Item.FindControl("") as HtmlContainerControl;
 span.InnerHtml = item.Value.ToString();

Answer 7

你在前台放一个label 把值装到里面绑定  在后台 fincontrol这个控件的ID  就可以取到了涩
