VSTO功能區組合框文本更改事件回調

Question

正在創建VS Outlook外接程序。

如何獲取組合框的文本更改事件。我想打電話給我的API來獲取數據，而用戶在組合框中

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

我的OnChange呼叫試圖回輸入一些文字，但它不能正常工作。但是在Ribbon Designer中我可以看到TextChange事件。

如何使用回調事件的文字變化

[ComVisible(true)] 
public class Ribbon : Office.IRibbonExtensibility 
{ 
    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"); 
    } 
    public void OnChange(Office.IRibbonControl control) 
    { 
     Debug.WriteLine("##### Am OnChange"); 
    } 
    public void GetText(Office.IRibbonControl control) 
    { 
     Debug.WriteLine("##### Am GetText"); 
    } 
    public void GetKeytip(Office.IRibbonControl control) 
    { 
     Debug.WriteLine("##### Am GetKeytip"); 
    }

     string[] resourceNames = asm.GetManifestResourceNames(); 
     for (int i = 0; i < resourceNames.Length; ++i) 
     { 
      if (string.Compare(resourceName, resourceNames[i], StringComparison.OrdinalIgnoreCase) == 0)

         return resourceReader.ReadToEnd(); 
        } 
       } 
      } 
     } 
     return null;

更改onChange回調的簽名從

public void OnChange(Office.IRibbonControl control) 

到

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

現在應該被調用。

另外，你應該從

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

改變getItemCount，getItemLabel，getText和getKeytip的簽名

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)
