Question

我有一个功能区，里面有一个按钮。当用户选择新文档时，我想更改功能区的按钮文本。我想我已经完成了所有工作，只有一行：

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        var wb = this.Application;
        ((Word.ApplicationEvents4_Event)wb).NewDocument += new Word.ApplicationEvents4_NewDocumentEventHandler(Application_NewDocument);

    }
    /// <summary>
    /// When the new button is pressed, the save should be enabled
    /// </summary>
    /// <param name="Doc"></param>
    void Application_NewDocument(Microsoft.Office.Interop.Word.Document Doc)
    {
    // set button's properties here
    }

Answer 1

最简单的方法是将事件处理程序放在Ribbon类中。然后你可以简单地使用：

this.Button.Label = "text";

否则，您必须创建一个将其封送到外部世界的属性：

功能区：

public string ButtonText {get {return this.Button.Label;} set {this.Button.Label = value;} }

在ThisAddIn中：

Globals.Ribbons.Ribbon.ButtonText = "text";

Answer 2

您需要调用功能区回调事件＆＃34; getlabel＆＃34;设置文本。在Newdocument事件中设置变量名称，如下面的示例代码所示，然后调用功能区InvalidateControl，它将重新绘制功能区并执行回调。

          <button id="btnTest" onAction="btnTest_Click" getLabel="get_LabelName" size="large" />

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        var wb = this.Application;
        ((Word.ApplicationEvents4_Event)wb).NewDocument += new Word.ApplicationEvents4_NewDocumentEventHandler(Application_NewDocument);

    }
    /// <summary>
    /// When the new button is pressed, the save should be enabled
    /// </summary>
    /// <param name="Doc"></param>
    void Application_NewDocument(Microsoft.Office.Interop.Word.Document Doc)
    {
        buttonText = "New Document Created";
        ribbon.InvalidateControl("btnTest");
    }

     public string get_LabelName(IRibbonControl control)
    {
        return buttonText;
    }
}
