jqgrid上的自定義按鈕不斷重新添加每個調用 - asp mvc

Question

我添加了一個自定義按鈕到工具欄的jqgrid在我的asp mvc模型，但每次調用獲取數據是從視圖到控制器OnDataRequested），該按鈕被重新添加。這意味着如果五次調用獲取數據，則會在jqgrid中產生五個單獨的按鈕。我究竟做錯了什麼？

這是我的代碼。謝謝。

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; 
     } 

格之格=新的{ToolBarSettings = {ShowRefreshButton = TRUE，ShowSearchButton = TRUE，ShowSearchToolBar = TRUE， ToolBarAlign = ToolBarAlign.Left，CustomButtons =新名單 { 新JQGridToolBarButton { 文本=「添加to Library「， ToolTip =」將選定的會話添加到我的地址「， ButtonIcon =」ui-icon-plusthick「， Position = ToolBarButtonPositi on.Last， 的OnClick = 「AddMultipleSessionsToLibrary」， } }}，

我在我的LibraryGrid類中添加自定義按鈕。感謝您的幫助。

首先，從GridModel中刪除自定義按鈕。然後，僅將它添加到索引動作調用中。
型號：

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; 
    }
