jqgrid上的自定义按钮在每次调用时都会重新添加 - asp mvc

Question

我在我的asp mvc模型中的jqgrid的工具栏中添加了一个自定义按钮，但是每次从视图调用获取数据到控制器（OnDataRequested）时，都会再次重新添加该按钮。这意味着如果五次调用来获取数据，则会在 jqgrid 上产生五个单独的按钮。我做错了什么？

这是我的代码。谢谢。

public virtual ActionResult Index()
        {
            var gridModel = new LibraryGridModel();
             SetupGrid(gridModel.LibraryGrid);
             return View(gridModel);
        }

         public virtual JsonResult OnDataRequested()
        {
             var gridModel = new LibraryGridModel();
              return gridModel.LibraryGrid.DataBind(GetFullLibrary().AsQueryable());
        }

     public void SetupGrid(JQGrid grid)
        {
            grid.DataUrl = Url.Action("OnDataRequested","Library");
            grid.MultiSelect = true;
            grid.MultiSelectMode = MultiSelectMode.SelectOnCheckBoxClickOnly;
        }

Grid grid = new{ ToolBarSettings = { ShowRefreshButton = true, ShowSearchButton = true, ShowSearchToolBar = true, ToolBarAlign = ToolBarAlign.Left, CustomButtons = 新列表 { 新的 JQGridToolBarButton { Text = "添加到库", ToolTip = "将选定的会话添加到我的", ButtonIcon = "ui-icon-plusthick", 位置 = ToolBarButtonPosition.Last, OnClick = "AddMultipleSessionsToLibrary", } }}，

我正在我的 LibraryGrid 类中添加自定义按钮。感谢您的帮助。

首先，从 GridModel 中移除自定义按钮。然后，仅将其添加到索引操作调用中。
型号：

Grid grid = new{ ToolBarSettings = { ShowRefreshButton = true, ShowSearchButton = true, ShowSearchToolBar = true, ToolBarAlign = ToolBarAlign.Left }},

控制器：

public virtual ActionResult Index()
            {
                var gridModel = new LibraryGridModel();
                gridModel.ToolBarSettings.CustomButtons.Add(
                     new JQGridToolBarButton
                     {
                         Text = "Add to Library",
                         ToolTip = "Add the selected session to mine",
                         ButtonIcon = "ui-icon-plusthick",
                         Position = ToolBarButtonPosition.Last,
                         OnClick = "AddMultipleSessionsToLibrary"
                     }
                 );
                 SetupGrid(gridModel.LibraryGrid);
                 return View(gridModel);
            }
         public virtual JsonResult OnDataRequested()
        {
             var gridModel = new LibraryGridModel();
              return gridModel.LibraryGrid.DataBind(GetFullLibrary().AsQueryable());
        }

 public void SetupGrid(JQGrid grid)
    {
        grid.DataUrl = Url.Action("OnDataRequested","Library");
        grid.MultiSelect = true;
        grid.MultiSelectMode = MultiSelectMode.SelectOnCheckBoxClickOnly;
    }
