我想在第三级repeate（RptMenuTol） 的ItemDataBound事件中获取 第一级repeater（RptCountView） 和第二级repeater（RptMenuTol） 中的值  跪求答案   

Answer 1

我给你说下思路Repeater1 在ItemDataBound的时候，你会在里面e.Item.FindControl 找到Repeater2
Repeater2 在ItemDataBound的时候，你会在里面e.Item.FindControl 找到Repeater3
这个时候Repeater3在ItemDataBound的时候，你需要找到Repeater1 和 Repeater2的控件你只需要提取两个变量int _repeaterItemIndex1;
int _repeaterItemIndex2;然后在ItemDataBound1 的时候这样写        void Repeater3_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {            if (e.Item.ItemType == ListItemType.Item)
            {
                RepeaterItem item1= Repeater1.Items[_repeaterItemIndex1];
                RepeaterItem item2= Repeater2.Items[_repeaterItemIndex2];                item1.FindControl("你需要在Repeater1找的控件");
                item2.FindControl("你需要在Repeater2找的控件");
            }        }然后对找到的控件赋值即可        void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {            if (e.Item.ItemType == ListItemType.Item)
            {
                _repeaterItemIndex1 = e.Item.ItemIndex;
            }        }Repeater2类似
因为执行顺序是这样的Repeater1的ItemDataBound->Repeater2的ItemDataBound->Repeater3的ItemDataBound
所以你在Repeater3的ItemDataBound中可以这样写

                item2.FindControl("你需要在Repeater2找的控件");
            }        }然后对找到的控件赋值即可
刚才排版乱了

Answer 3

用e.Item.NamingContainer.FindControl("HDMenuTitle")获取第二层Repeater中的HiddenField控件，用e.Item.NamingContainer.NamingContainer.FindControl("HdEid")获取第一层Repeater中的HiddenField控件。

Answer 4

尽量不要想当然地去瞎FindControl。保证正确的组合关系，对于倒置了的关系，应该使用事件通讯，而不是什么FindControl。
