如何动态添加组合框项目？

我有一个组合框，我将在OnChange Call Back事件期间调用API。将项目加载到组合框时遇到问题

    public void OnChange(Office.IRibbonControl control, string text)
    {            
        var result = GETMembersList("https://restcountries.eu/rest/v1/all");

        var members = from member in result
                      select member;

        foreach (var member in members)
        {
            dsMember mem = new dsMember();
            mem.Id = member["numericCode"].ToString();
            mem.Name = member["name"].ToString();

            RibbonDropDownItem item = Globals.Factory.GetRibbonFactory().CreateRibbonDropDownItem();
            item.Label = mem.Name;
            **cmbMembers.Items.Add(item);** ?? //problem here, cant access the combo box
        }

Ribbon.xml

    <?xml version="1.0" encoding="UTF-8"?>
<customUI onLoad="Ribbon_Load" xmlns="http://schemas.microsoft.com/office/2006/01/customui">
  <ribbon>
    <tabs>
      <tab id="tabTest" label="TEST">
        <group id="grpTest">
          <comboBox id="cmbMembers" label="Users" showImage="false" 
                  onChange="OnChange"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

Answer 1

VISTO有一个问题，我也试过从代码中添加多个项目，但出了点问题。但是，可以动态修改现有项目。尝试在Ribbon1_Load事件中进行编辑。

public partial class Ribbon1
{
    private void Ribbon1_Load(object sender, RibbonUIEventArgs e)
    {
        this.comboBox1.Items[0].Label = "new Lable";
    }
}

尝试一下：

 RibbonDropDownItem item = Factory.CreateRibbonDropDownItem();

VSTO Ribbon Combo Box动态添加项目
