VSTO 功能区组合框文本更改事件回调

Question

正在创建 VS Outlook 插件。

如何获取组合框的Text changes事件。当用户在组合框中输入一些文本时，我想调用我的 API 来检索数据

          <comboBox id="cmbUsers" label="Users" showImage="false" 
               getItemCount="OnGetItemCount"
              getItemLabel="OnGetItemLabel"
              onChange="OnChange"
                getText="GetText"
                getKeytip="GetKeytip"/>

我尝试使用 OnChange 回调，但它不起作用。但是在功能区设计器中我可以看到 TextChange 事件。

如何使用回调事件进行文本更改

    private Office.IRibbonUI ribbon;

    public Ribbon()
    {
    }

    #region IRibbonExtensibility Members

    public string GetCustomUI(string ribbonID)
    {
        return GetResourceText("UserOutlookAddin.Ribbon.xml");
    }

    #endregion

    #region Ribbon Callbacks
    //Create callback methods here. For more information about adding callback methods, select the Ribbon XML item in Solution Explorer and then press F1

    public void Ribbon_Load(Office.IRibbonUI ribbonUI)
    {
        this.ribbon = ribbonUI;



    }

    public void OnActionCallback(Office.IRibbonControl control)
    {
        if (control.Id == "checkBox1")
        {
            MessageBox.Show("You clicked " + control.Id);
        }
        else
        {
            MessageBox.Show("You clicked a different control.");
        }
    }
    public void OnGetItemCount(Office.IRibbonControl control)
    {
        Debug.WriteLine("##### Am OnGetItemCount");
    }
    public void OnGetItemLabel(Office.IRibbonControl control)
    {
        Debug.WriteLine("##### Am OnGetItemLabel");

Answer 1

将 onChange 回调的签名更改为

public void OnChange(Office.IRibbonControl control)

到

public void OnChange(Office.IRibbonControl control, string text)

现在应该调用它了。

此外，您应该将 getItemCount、getItemLabel、getText 和 getKeytip 的签名从

更改为

public void OnGetItemCount(Office.IRibbonControl control)
public void OnGetItemLabel(Office.IRibbonControl control)
public void GetText(Office.IRibbonControl control)
public void GetKeytip(Office.IRibbonControl control)

到

public int OnGetItemCount(Office.IRibbonControl control)
public string OnGetItemLabel(Office.IRibbonControl control, int index)
public string GetText(Office.IRibbonControl control)
public string GetKeytip(Office.IRibbonControl control)
