如何获取DataList里的控件

如何获取DataList里的控件
比如说，我在里面放了一个DIV 我要通过里面的LinkButton1_Click  来实现隐藏和显示DIV 的功能，但不知道怎么获取DIV 这个控件的可视性！ --------------------编程问答-------------------- 人呢，怎么没人顶啊 --------------------编程问答-------------------- js端行不.

div.style.display = none/block --------------------编程问答-------------------- 楼上能不能详细点！ --------------------编程问答-------------------- document.all("divName").style.display = "none";
document.all("divName").style.display = "block";

--------------------编程问答-------------------- 前台

     <div id="ff">
      <asp:Button ID="Button3" runat="server" Text="del" UseSubmitBehavior="false"/>
      </div>

后台

    Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click
        Me.RegisterStartupScript("", "<script language=javascript defer>document.getElementById('ff').style.display = 'none';</script>")
    End Sub --------------------编程问答-------------------- 或者后台

    Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click
        Me.ClientScript.RegisterClientScriptBlock(Me.GetType(), "", "<script language=javascript defer>document.getElementById('ff').style.display = 'none';</script>")
    End Sub
--------------------编程问答-------------------- 在_ItemDataBind()事件里写如下语句
(LinkButton)e.item.FindControl("LinkButton1")就能获取你想要的里面的LinkButton控件了 --------------------编程问答-------------------- protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        LinkButton link = (LinkButton)e.Item.FindControl("link1");
        link.Attributes.Add("onclick", "javescript:DivShow()");
    }

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> --------------------编程问答-------------------- 顶！！ --------------------编程问答-------------------- http://blog.csdn.net/xianfajushi/archive/2008/11/30/3413317.aspx
