DataList里的控件ID获取例子

以 LinkButton为例
前台：

<script   language= "javascript "> 
function   DivShow() 
{ 
        alert( "dddd "); 
        var   div=document.getElementById( "div1 "); 
        if(div.style.display   = "none ") 
        { 
                div.style.display   = "none " 
        } 
        else 
        { 
                div.style.display   = "none " 
        } 
} 

</script> 
datalist 
  <asp:DataList   ID= "DataList1 "   runat= "server "   BorderStyle= "Dotted "   
                onitemdatabound= "DataList1_ItemDataBound "> 
                
                <ItemTemplate> 
                        <table> 
                                <tr                                         <td> <asp:LinkButton   ID= "link1 "   runat= "server "   Text= "show "> </asp:LinkButton> </td> 
                                        <td>   <div   id= "div1 "> 
                        aaaaashow   
                        </div> 
                        </td> 
                                </tr> 
                                
                        </table> 
                </ItemTemplate> 
        </asp:DataList> 

后台：

protected   void   DataList1_ItemDataBound(object   sender,   DataListItemEventArgs   e) 
        { 
                LinkButton   link   =   (LinkButton)e.Item.FindControl( "link1 "); 
                link.Attributes.Add( "onclick ",   "javescript:DivShow() "); 
        } 

其实就是DataList onitemdatabound 事件的使用
