[转载]Repeater三层嵌套

两层嵌套

 protected  void  rpt_ItemDataBound(object  sender,  RepeaterItemEventArgs  e)
{ 
   if   (e.Item.ItemType   ==   ListItemType.Item   ||   e.Item.ItemType   ==   ListItemType.AlternatingItem) 
     { 
        Repeater   rpt   =   (Repeater)e.Item.FindContro( "rpt_Level04 "); 
        int   typeFatherID   =   ((CommonType)e.Item.DataItem).TypeID; 
        rpt.DataSource   =   da.GetAllNodeInfo(tt,   typeFatherID); 
        rpt.DataBind(); 
     }
}

三层嵌套

protected  void  rpt_Level02_ItemDataBound(object  sender,  RepeaterItemEventArgs  e)
{ 
        if   (e.Item.ItemType   ==   ListItemType.Item   ||   e.Item.ItemType    ==ListItemType.AlternatingItem) 
     { 
        Repeater   rpt   =   (Repeater)e.Item.FindControl( "rpt_Level03 "); 

//给下一层repeater绑定事件
      rpt.ItemDataBound   +=   new   RepeaterItemEventHandler(rpt_ItemDataBound);// <==这里是关键 
        int   typeFatherID   =   ((CommonType)e.Item.DataItem).TypeID; 
        rpt.DataSource   =   da.GetAllNodeInfo(tt,   typeFatherID); 
        rpt.DataBind(); 
     } 
} 

protected   void   rpt_ItemDataBound(object   sender,   RepeaterItemEventArgs   e)
{ 
     if   (e.Item.ItemType   ==   ListItemType.Item   ||   e.Item.ItemType   ==   ListItemType.AlternatingItem) 
       { 
        Repeater   rpt   =   (Repeater)e.Item.FindControl( "rpt_Level04 "); 
        int   typeFatherID   =   ((CommonType)e.Item.DataItem).TypeID; 
        rpt.DataSource   =   da.GetAllNodeInfo(tt,   typeFatherID); 
        rpt.DataBind(); 
        }
}
