如何在表格行的 asp onclick 调用中传递参数？

Question

这里我在列表视图中有一个表格行，声明如下：

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

我在后端调用一个回发方法，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>
                        <td runat="server" style="width: 20%;">SERIAL #</td>
                        <td runat="server" style="width: 12%; text-align:center">DAR STATUS</td>
                        <td runat="server" style="width: 18%; text-align:right;">SHIP DATE</td>  
                    </tr>
                    <tr id="ItemPlaceholder" runat="server">
                    </tr>

注册回发调用时 - 第二个参数将是参数：

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