2 publicstring Dir
3 {
4 get
5 {
6 return _dir;
7 }
8 set
9 {
10 _dir = value;
11 }
12 }

14 protectedvoid Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
15 {
16 DataRowView dr = e.Item.DataItem as DataRowView;
17 string item_id = dr["ItemFamilyID"].ToString();//companyid ='TEXFACTOR' and
18 string sql ="select * from Tab where companyid ='aa' and ItemFamilyID='"+ item_id +"'";
19 DataSet dsid = child.Query(sql);
20 (e.Item.FindControl("Repeater2") as Repeater).DataSource = dsid;
21 (e.Item.FindControl("Repeater2") as Repeater).DataBind();
22 }

左边的这个菜单是在母版页里面
当点击子节点，显示相关数据在右边，同时页面会刷新
刷新后，子菜单收起来了，我需要它还是展开的

为什么不用框架页呢，用框架页后，左侧的链接控制右侧的页面，多好啊

用框架，也要嵌套在母版页里面，但是母版页一刷新，整个页面都会跟着刷新的啊
@青 草 香:导航菜单就 没必要用母板页了吧，楼主自己看，也可以用scriptManager 用局部刷新啊
我用的使用户自定义控件
