Question

为共享邮箱创建自定义的“代表发送”按钮，我想创建RibbonGroup和RibbonButton并以编程方式将它们添加到RibbonTab中。

我的问题是，在CreateButtons()中，向RibbonGroup和RibbonTab添加按钮会导致错误“集合是只读的” 。即使这些也用于设计器中。

RibbonGroupReply.Items.Add(tempButton);
RibbonGroupNew.Items.Add(tempButton);
this.tab_MainComplement.Groups.Add(RibbonGroupNew);

我还尝试使用设计器中的其他方法，现在可以在RibbonGroup中添加，但不能在RibbonTab中添加：

tab_MainComplement.SuspendLayout();
RibbonGroupReply.SuspendLayout();
this.SuspendLayout();

我认为没有办法，因为删除新标签会在上引发相同的错误 this.Tabs.Add(New_Tab);并在设计器CreateButtons中添加InitializeComponent方法会破坏布局，并且不会产生更好的结果。

代码：

public partial class BtnSender
{
    internal List<ButtonInfo> Buttons;

    private void BtnSender_Load(object sender, RibbonUIEventArgs e)
    {
        LoadButtonsList();
        CreateButtons();
    }

    private void CreateButtons()
    {
        //CreateNew Group           
        var buttonsNew = Buttons.Where(x => (x.Type & ButtonType.New) == 0);
        if (buttonsNew.Any())
        {
            OutlookRibbon.RibbonGroup RibbonGroupNew = this.Factory.CreateRibbonGroup();

            RibbonGroupNew.Label = "Nouveau Message";
            RibbonGroupNew.Name = "Nouveau Message";

            foreach (var butt in buttonsNew)
            {
                var tempButton = this.Factory.CreateRibbonButton();
                tempButton.ControlSize = RibbonControlSize.RibbonControlSizeLarge;
                tempButton.Image = global::CustomExpeditor.Properties.Resources.basic_mail;
                tempButton.Label = butt.Label;
                tempButton.Name = butt.Name + butt.Label.Replace(" ", string.Empty) + "New";
                tempButton.Description = butt.Address;
                tempButton.ShowImage = true;
                tempButton.Click += new Microsoft.Office.Tools.Ribbon.RibbonControlEventHandler(this.Btn_SenderSI_Click);
                RibbonGroupNew.Items.Add(tempButton);
            }
            this.tab_MainComplement.Groups.Add(RibbonGroupNew);
        }

        //CreateReply Group
        var buttonsReply = Buttons.Where(x => (x.Type & ButtonType.Reply) == ButtonType.Reply);
        if (buttonsReply.Any())
        {
            OutlookRibbon.RibbonGroup RibbonGroupReply = this.Factory.CreateRibbonGroup();
            //tab_MainComplement.SuspendLayout();
            //RibbonGroupReply.SuspendLayout();
            //this.SuspendLayout();

            RibbonGroupReply.Label = "Répondre à";
            RibbonGroupReply.Name = "Répondre à";

            foreach (var butt in buttonsNew)
            {
                var tempButton = this.Factory.CreateRibbonButton();
                tempButton.ControlSize = RibbonControlSize.RibbonControlSizeLarge;
                tempButton.Image = global::CustomExpeditor.Properties.Resources.basic_mail;
                tempButton.Label = butt.Label;
                tempButton.Name = butt.Name + butt.Label.Replace(" ", string.Empty) + "Reply";
                tempButton.Description = butt.Address;
                tempButton.ShowImage = true;
                tempButton.Click += new Microsoft.Office.Tools.Ribbon.RibbonControlEventHandler(Btn_ResponseSI_Click);
                RibbonGroupReply.Items.Add(tempButton);
            }
            tab_MainComplement.Groups.Add(RibbonGroupReply);
        }
    }

    private void LoadButtonsList()
    {
        // Will evolve to a more configurable list in the future. 
        Buttons = new[] {
            new ButtonInfo{ Label="Mail Test", Address="MailTest@domain.not", Type=ButtonType.New & ButtonType.Reply },
            new ButtonInfo{ Label="Serv Info", Address="MailTest@domain.not", Type=ButtonType.New & ButtonType.Reply  },
            new ButtonInfo{ Label="Serv Log", Address="MailTest@domain.not", Type=ButtonType.New & ButtonType.Reply  },
            new ButtonInfo{ Label="Titi", Address="MailTest@domain.not", Type=ButtonType.New  }
        }.ToList();
    }
}

public class ButtonInfo
{
    public string Name, Label, Address;
    public ButtonType Type;
}
[Flags] public enum ButtonType { New = 1, Reply = 2 };

Answer 1

这些按钮在初始化后即是只读的，就像组，选项卡等。初始化后动态添加它们是行不通的。

我已经解决了几次，方法是在前面添加按钮，并用正确的标签动态填充按钮。某些控件类型确实允许使用动态按钮，例如功能区库。

通过按钮以编程方式填充功能区
