三、gridView增删改查

1. 新增或修改一条数据

　　1.1 添加 新增或修改按钮

    <div style=" 120px; float: right; padding-top: 3px">
        @Html.DevExpress().Button(settings =>
        {
            settings.Name = "btnUpdate";
            settings.ControlStyle.CssClass = "button";
            settings.Text = "修改";
            settings.UseSubmitBehavior = true;
            settings.ClientSideEvents.Click = "updateData";
        }).GetHtml()
    </div>

    <div style=" 120px; float: right; padding-top: 3px">
        @Html.DevExpress().Button(settings =>
        {
            settings.Name = "btnAdd";
            settings.ControlStyle.CssClass = "button";
            settings.Text = "新增";
            settings.UseSubmitBehavior = true;
            settings.ClientSideEvents.Click = "addData";
        }).GetHtml()
    </div>

　　1.2 新增或修改按钮JS

    function updateData(s, e) {
        GridView.GetSelectedFieldValues("DocumentId", GetSelectedFieldValuesCallbackForModify);
    }

    function GetSelectedFieldValuesCallbackForModify(values) {
        if (values.length != 1) {
            alert("请选择一个修改项");
        } else {
            $.ajax({
                type: "GET",
                url: '@Url.Action("UpdateOrAdd", "Home")',
                data: { "id": values[0] },
                datatype: "html",
                ansy: false,
                cache: false,
                success: function (data) {
                    $('#content').html(data);
                    $("#DocumentId").val(values[0]);
                    addorUpdate.Show();
                },
                error: function () {
                    alert("处理失败!");
                }
            });
        }
    }

    function addData(s, e) {
        $.ajax({
            type: "GET",
            url: '@Url.Action("UpdateOrAdd", "Home")',
            data: '',
            datatype: "html",
            ansy: false,
            cache: false,
            success: function (data) {
                $('#content').html(data);
                addorUpdate.Show();
            },
            error: function () {
