VSTO 功能區組合框文本更改事件回調

Question

我正在創建 VS Outlook 插件。

如何獲取組合框的文本更改事件。 當用戶在組合框中輸入一些文本時，我想調用我的 API 來檢索數據

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

我嘗試使用 OnChange 回調，但它不起作用。 但是在功能區設計器中，我可以看到 TextChange 事件。

如何使用回調事件進行文本更改

Answer 1

將onChange回調的簽名從

public void OnChange(Office.IRibbonControl control)

到

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

現在它應該被調用。

此外，您應該將getItemCount 、 getItemLabel 、 getText和getKeytip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)

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)
