Question

这里我在listview中有一个表行，声明如下：

<tr onclick="<%= _jsPostBackCall %>;" />

我在后端调用了一个回发方法，但必须得到tr索引：

    public void RaisePostBackEvent(string eventArgument)
    {
        //selected index here
    }

aspx页面内容 - 下面是aspx页面中的html。这包含列表视图。

<asp:ListView ID="lvEquipmentList" runat="server" OnSelectedIndexChanged="lvEquipmentList_SelectedIndexChanged" OnSelectedIndexChanging="lvEquipmentList_SelectedIndexChanging">
            <LayoutTemplate>
                <table runat="server" class="TableCSS">
                    <tr runat="server" class="TableHeader">  
                        <td runat="server" style="width: 30%;">PRODUCT LINE</td>  
                        <td runat="server" style="width: 20%;">MODEL</td>

注册回发时，第二个参数是参数：

_jsPostBackCall = ClientScript.GetPostBackEventReference(this, "The Parameter");

如何在表格行中的asp onclick调用中传递参数？
