使用自定义编辑按钮以编辑模式打开DevExpress MVC网格

Question

我正在使用Devexpress MVC网格，并添加了两个自定义按钮（“编辑和复制”），并且正在执行操作。使用复制按钮，我将使用现有数据创建一条新记录，并在“添加新行模式”下打开网格。

以下是代码：

@Html.DevExpress().GridView(grid =>
{
    grid.Name = "gvInformation";
    grid.SettingsDetail.AllowOnlyOneMasterRowExpanded = true;
   grid.SettingsEditing.Mode = GridViewEditingMode.EditForm;

    //Callback Events
    grid.CallbackRouteValues = new { Controller = "Case", Action = "InformationGridContent"};
    grid.SettingsEditing.AddNewRowRouteValues = new { Controller = "Case", Action = "AddInformationRecord" };
    grid.SettingsEditing.UpdateRowRouteValues = new { Controller = "Case", Action = "UpdateInformationRecord" };
    grid.SettingsEditing.DeleteRowRouteValues = new { Controller = "Case", Action = "DeleteInformationRecord" };
    grid.ClientSideEvents.BeginCallback = "BeginGridCallback";
    grid.BeforeGetCallbackResult = (sender, e) =>
    {
        MVCxGridView gridView = sender as MVCxGridView;
        if (isCopyRequired)
            gridView.AddNewRow();

        if (gridView.IsNewRowEditing)
        {
            gridView.SettingsText.CommandUpdate = Html.Raw("<span id='btnGridAdd'>Add</span>").ToHtmlString();
            gridView.SettingsText.CommandCancel = Html.Raw("<span id='btnGridCancel'>Cancel</span>").ToHtmlString();
        }

        if (!gridView.IsNewRowEditing)
        {
            gridView.SettingsText.CommandUpdate = Html.Raw("<span id='btnGridUpdate'>Update</span>").ToHtmlString();
            gridView.SettingsText.CommandCancel = Html.Raw("<span id='btnCancel'>Cancel</span>").ToHtmlString();
        }
    };

        //Custom Copy Record Button
    var btnCopy = new GridViewCommandColumnCustomButton { ID = "btnCopy" };
    btnCopy.Text = "<i class=\"fa fa-copy fa-lg\" title='Copy'></i>";
    grid.CommandColumn.CustomButtons.Add(btnCopy);

    //Custom Edit Button
    var btnEdit = new GridViewCommandColumnCustomButton { ID = "btnEdit" };
    btnEdit.Text = "<i class=\"fa fa-pencil fa-lg\" title='Edit'></i>";
    grid.CommandColumn.CustomButtons.Add(btnEdit);

    //Custom Button Events
    grid.ClientSideEvents.CustomButtonClick = "OnCustomButtonClick";
    grid.CustomActionRouteValues = new { Controller = "Case", Action = "CustomInformationRecord" };
    }

客户端事件：

var buttonCommand;
function OnCustomButtonClick(s, e) {
    buttonCommand = e.buttonID;
    s.PerformCallback();
}

function BeginGridCallback(s, e) {
    //Grid Edit Button Click Event
    if (buttonCommand === "btnEdit") {
        e.customArgs["buttonCommand"] = "btnEdit";
    }

    //Grid Copy Button Click Event
    if (buttonCommand === "btnCopy") {
        e.customArgs["buttonCommand"] = "btnCopy";
    }
}

对于“复制”按钮和在“编辑表单”模式下打开网格，它工作正常，但是当单击“编辑”按钮时，未在“编辑”模式下打开网格。有什么我想念的吗？
