按下选择时，网格视图选择所有行

Question

我有gvCustomers，它在运行时使用webMethod和jquery填充。当我在命令字段中单击选择按钮时，将选中所有行。 我非常感谢你的帮助。

这是我的javascript文件

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
        $(function () {
            if ($('#ContentPlaceHolder1_txtBuscador').val() == '') {
                GetCustomers(1);
            } else {
                GetCustomersBuscar(1);
            }
        });


        $("body").on("click", "#ContentPlaceHolder1_buscar", function () {

            GetCustomersBuscar(1);
        });
