我有一个中继器，该中继器具有按照以下代码编写的表格，单击表格行时，我需要向后面的代码发送参数。目前，我在LinkButton1上单击了它。我也尝试过在LinkButton中包装，但无法正常工作我该怎么做呢？

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand" OnItemDataBound="Repeater1_ItemDataBound" OnItemCreated="Repeater1_ItemCreated">
    <HeaderTemplate>
        <table class="table table-striped table-bordered dttable dataTable no-footer" style="border-style: solid; border-color: rgb(252, 253, 250); text-align: center; font-weight: 700; width: 100%;" id="JsDataTable" role="grid" aria-describedby="JsDataTable_info">
            <thead style="width: 100%">

我猜您想要CommandArgument中Repeater1_ItemCommand的值。但是，如果您尝试将发件人强制转换为LinkButton，则该按钮将无效，因为发件人是中继器，而不是内部的按钮。

因此强制转换CommandSource并获取正确的值。

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    LinkButton lb = e.CommandSource as LinkButton;
    Label1.Text = lb.CommandArgument;
}

您不能直接绑定tr点击，因此必须使用技巧。您可以使用jQUery将LinkButton的点击设置为行本身。

<table border="1" id="Repeater1Table">
    <asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
        <ItemTemplate>
            <tr>
                <td>Click here</td>
                <td>
                    <asp:LinkButton ID="LinkButton1" runat="server" CommandName="PlayPrev" CommandArgument='<%#Eval("Id") %>' Text='<%#Eval("Name") %>' CssClass="name"></asp:LinkButton>
                </td>
            </tr>
        </ItemTemplate>
    </asp:Repeater>
</table>

<script type="text/javascript">
    $(document).ready(function () {
        $("#Repeater1Table tr").each(function () {
            var href = $(this).find(".name").prop("href").split(":")[1];
            $(this).attr("onclick", href); 
        });
    });
</script>

表行服务器端单击中继器？
