ToolStripPanel加入方法不是將工具條添加到面板

Question

我對ToolStripPanel.Join有一個非常奇怪的問題，我一直在Google和SO上搜索關於我做錯什麼的線索，但是我可以'弄明白了。基本上，當我使用ToolStripPanel.Join時，我添加的第一個ToolStrip根本不出現在ToolStripPanel中，但我加入的所有其他ToolStrips都會出現。在我深入細節之前，首先讓我說我正在使用C＃和VS 2010和.NET 4，並且，對於某些上下文，我試圖在用戶控件上使用ToolStripPanel，它位於自定義DLL，我們做了這樣我們可以在其他形式重用這些用戶控件。

我以前使用的是ToolStripContainer，但是我決定換用ToolStripPanel，因爲我們只需要ToolStripContainer的頂部面板;我沒有看到使用ToolStripContainer的重點。由於我無法在工具箱中找到ToolStripPanel控件，因此我決定將其自己​​添加到Designer.cs文件中。以下是我做的：

private ToolStripPanel tsPanel; 
<--Other code here--> 
private void InitializeComponent() 
{ 
    this.tsPanel = new System.Windows.Forms.ToolStripPanel(); 
    <--Other code here--> 
    // 
    // tsPanel 
    // 
    this.tsPanel.Dock = System.Windows.Forms.DockStyle.Top; 
    this.tsPanel.Location = new System.Drawing.Point(0, 0); 
    this.tsPanel.Margin = new System.Windows.Forms.Padding(3); 
    this.tsPanel.Name = "tsPanel"; 
    this.tsPanel.Orientation = System.Windows.Forms.Orientation.Horizontal; 
    this.tsPanel.RowMargin = new System.Windows.Forms.Padding(3, 0, 0, 0); 
    this.tsPanel.Size = new System.Drawing.Size(1000, 0); 
    <--Other code here--> 
    // 
    // MFDesigner 
    // 
    this.BackColor = System.Drawing.Color.Gainsboro; 
    <--Add other controls to UC Controls collection--> 
    this.Controls.Add(this.tsPanel); 
    this.ForeColor = System.Drawing.Color.Black; 
    this.Name = "MFDesigner"; 
    this.Size = new System.Drawing.Size(1000, 670); 
    this.Load += new System.EventHandler(this.MultiFormatDesignerControl_Load); 
    this.Resize += new System.EventHandler(this.MFDesigner_Resize); 
    this.pnlToolbox.ResumeLayout(false); 
    this.pnlProperties.ResumeLayout(false); 
    this.ResumeLayout(false); 
    this.PerformLayout(); 
} 

然後，在用戶控件的構造，我有：

public MFDesigner() 
{ 
    InitializeComponent(); 
    <--Other code here--> 
    ToolStripButton[] openSaveButtonArr = new ToolStripButton[]{ 
     //The createToolStripButton method creates toolstrip buttons using some simple 
     //parameters. 
     createToolStripButton("Open", Images.CmdOpen, new EventHandler(this.OnOpen), "Open saved file"), 
     createToolStripButton("Save", Images.CmdSave, new EventHandler(this.OnSaveToDisk), "Save to disk") 
    }; 
    ToolStrip openSaveToolStrip = new ToolStrip(openSaveButtonArr); 
    tspanel.Join(openSaveToolStrip); 
    <--Other code here--> 
} 

因爲我們正在創建工具條，並在代碼中把它們添加到ToolStripPanel中，我可以」不要在設計器中看到用戶控件的外觀。所以，我構建了dll，然後轉到另一個單獨項目中的另一個表單，該表單使用dll中的用戶控件，當表單打開時，沒有工具條;它根本不會出現。雖然這是奇怪的事情。如果我添加只是多了一個工具條的面板，第二工具條就會出現：

public MFDesigner() 
{ 
    InitializeComponent(); 
    <--Other code here--> 
    ToolStripButton[] openSaveButtonArr = new ToolStripButton[]{ 
     //The createToolStripButton method creates toolstrip buttons using some simple 
     //parameters. 
     createToolStripButton("Open", Images.CmdOpen, new EventHandler(this.OnOpen), "Open saved file"), 
     createToolStripButton("Save", Images.CmdSave, new EventHandler(this.OnSaveToDisk), "Save to disk") 
    }; 
    ToolStrip openSaveToolStrip = new ToolStrip(openSaveButtonArr); 
    tspanel.Join(openSaveToolStrip, 1); 
    ToolStripButton[] openSaveButtonArr2 = new ToolStripButton[]{ 
     createToolStripButton("Open2", Images.CmdOpen, new EventHandler(this.OnOpen), "Open saved rpx file 2"), 
     createToolStripButton("Save2", Images.CmdSave, new EventHandler(this.OnSaveToDisk), "Save to disk 2") 
    }; 
    ToolStrip openSaveToolStrip2 = new ToolStrip(openSaveButtonArr2); 
    tsPanel.Join(openSaveToolStrip2, 1); 
    <--Other code here--> 
} 

在上面的代碼中，我創建將不會出現在第一工具條，但第二個（openSaveToolStrip2）將出現。順便說一句，如果我只爲這兩個工具條使用Join overload Join（toolStrip），則不會顯示任何內容。另外，如果我將工具條添加到其他行，即tsPanel.Join（toolstrip3,2）或tsPanel.Join（toolstrip4,3），將出現工具條。

對於一些令人費解的（至少對我來說）理由來說，我添加的第一個工具條永遠不會出現，但所有後續的工具條都會這樣做。作爲一種解決方法，我一直在創建一個虛擬工具條，添加它，然後添加我所有的真實工具條。這感覺很不方便，所以我很想弄清楚爲什麼會發生這種情況。我試圖按照文檔on MSDN，但我仍然必須失去一些東西，因爲我無法想象這樣的錯誤沒有得到修復。

有沒有人知道這裏可能會出錯？與工具條面板中的所有工具條

我把你的代碼，並刪除雜散成員，這樣我可以編譯或東西，是不相關的您的問題正在運行的應用的

Answer 1

截圖（例如：// private Panel pnlToolbox; // private Panel pnlProperties;）。我創建了運行時工具條並將它們加入到了面板中，與您的操作相同。我也提供了自己的實現createToolStripButton因爲你沒有。第三個工具條使用Image.FromStream和網絡資源，因爲我缺乏本地的。有或沒有圖像，我沒有任何故障......

    private ToolStripPanel tsPanel; 
    //private Panel pnlToolbox; 
    //private Panel pnlProperties;   

    public MFDesigner () 
    { 
     InitializeComponent(); 
     // 
     // first toolstrip 
     // 
     ToolStripButton tsbOpen = new ToolStripButton("Open", null, new EventHandler(this.OnOpen), "Open saved file"); 
     ToolStripButton tsbSave = new ToolStripButton("Save", null, new EventHandler(this.OnSaveToDisk), "Save to disk"); 
     ToolStripButton[] openSaveButtonArr = new ToolStripButton[] { tsbOpen, tsbSave }; 
     ToolStrip openSaveToolStrip = new ToolStrip(openSaveButtonArr) { CanOverflow = true }; 
     this.tsPanel.Join(openSaveToolStrip);  
     // 
     // second toolstrip 
     // 
     ToolStripButton tsbOpen2 = createToolStripButton("Open2", null, new EventHandler(this.OnOpen), "Open saved file"); 
     ToolStripButton tsbSave2 = createToolStripButton("Save2", null, new EventHandler(this.OnSaveToDisk), "Save to disk"); 
     ToolStripButton[] openSaveButtonArr2 = new ToolStripButton[] { tsbOpen2, tsbSave2 }; 
     ToolStrip openSaveToolStrip2 = new ToolStrip(openSaveButtonArr2) { CanOverflow = true }; 
     this.tsPanel.Join(openSaveToolStrip2, 1);  
     // 
     // third toolstrip 
     // 
     WebClient wc = new WebClient(); 
     byte[] bytes = wc.DownloadData("http://my.crestron.eu/images/icons/ico_folder_open.png"); 
     // You must keep the stream open for the lifetime of the Image. 
     MemoryStream msOpen = new MemoryStream(bytes); 
     System.Drawing.Image imgOpen = System.Drawing.Image.FromStream(msOpen); 

     bytes = wc.DownloadData("http://www.njrussians.com/images/save_ico.png"); 
     MemoryStream msSave = new MemoryStream(bytes); 
     System.Drawing.Image imgSave = System.Drawing.Image.FromStream(msSave); 
     ToolStripButton tsbOpen3 = createToolStripButton("Open3", imgOpen, new EventHandler(this.OnOpen), "Open saved file");
