想用datalist实现双击行的任意位置执行事件

[jpyc]

想用datalist，绑定数据后，双击行的任意位置，执行后台的代码，
如页面显示数据：
ID 产品名 说明
1 产品A A说明
2 产品B B说明
3 产品C C说明
4 产品D D说明

如果双击 1行的任意位置，马上把ID作为参数执行对应的后台代码.

最好给个相关的例子，谢谢大家。

不清楚的再补充。

点击dataList的时候获取其索引字段的的值

示例：

<asp:DataList ID="DataList1" runat="server" width="400px"
        OnItemCommand="DataList1_ItemCommand" OnItemDataBound="DataList1_ItemDataBound">
            <HeaderTemplate>
                任务列表
            </HeaderTemplate>
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server" Text="SingleClick" CommandName="SingleClick" Visible="false"/>
                <asp:LinkButton ID="LinkButton2" runat="server" Text="DoubleClick" CommandName="DoubleClick" Visible="false"/>
                <asp:Panel ID="Panel1" runat="server">
                    <span style="float:left;">
                        <b>编号: </b><%# Eval("Id") %>
                          <b>任务: </b><%# Eval("Task") %>
                    </span>
                    <span style="float:right;">
                        <b>是否完成: </b><%# Eval("IsDone") %>
                    </span>
                </asp:Panel>
            </ItemTemplate> 
            <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />    
            <ItemStyle BackColor="#F7F7DE" BorderStyle="Solid" BorderColor="lightgray" BorderWidth="1px" />
            <AlternatingItemStyle BackColor="white" />
            <SelectedItemStyle BackColor="#CE5D5A" /> 
        </asp:DataList>

    protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)

        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

            // Get the javascript which is assigned to this LinkButton
            string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");
            // To prevent the first click from posting back immediately 
            // (therefore giving the user a chance to double click) pause the

            _jsSingle = _jsSingle.Insert(11, "setTimeout(\"");
            _jsSingle += "\", 300)";

            Panel _itemPanelDouble = (Panel)e.Item.Controls[5];
            // Add this javascript to the ondblclick Attribute of the panel
            _itemPanelDouble.Attributes["ondblclick"] = _jsDouble;
        }
    }

    protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        DataList _dataList = (DataList)source;

        // Get the selected index and the command name
        int _selectedIndex = e.Item.ItemIndex;
        string _commandName = e.CommandName;

        switch (_commandName)
        {
            case ("SingleClick"):
                _dataList.SelectedIndex = _selectedIndex;
                this.Message.Text += "Single clicked DataList row at index " + _selectedIndex.ToString() + "<br />";
                break;
            case ("DoubleClick"):

首先要给DataList的行中添加双击事件
这个不需要再 给示例了吧！ 客户端控件的 ondblclick事件

[jpyc]

tr 里怎么加入 ondblclick 比较合理。因为DataList中，因为他本是生成的时候有一套table tr tb

我仔细看看啊。谢谢
