示例

下面的代码示例演示了在用户控件中实现的属性的使用 Verbs 。 可以在类概述主题的“示例”部分中 IWebActionable 找到此代码示例的完整代码。

代码示例的以下部分演示了用户控件中属性的 Verbs 自定义实现。

// This property implements the IWebActionable interface.
WebPartVerbCollection IWebActionable.Verbs
{
  get
  {
    if (m_Verbs == null)
    {
      ArrayList verbsList = new ArrayList();
      WebPartVerb onlyVerb = new WebPartVerb
        ("customVerb1", new WebPartEventHandler(IncrementVerbCounterClicks));
      onlyVerb.Text = "My Verb";
      onlyVerb.Description = "VerbTooltip";
      onlyVerb.Visible = true;
      onlyVerb.Enabled = true;
      verbsList.Add(onlyVerb);
      WebPartVerb otherVerb = new WebPartVerb
        ("customVerb2", new WebPartEventHandler(IncrementVerbCounterClicks));
      otherVerb.Text = "My other Verb";
      otherVerb.Description = "Other VerbTooltip";
      otherVerb.Visible = true;
      otherVerb.Enabled = true;
      verbsList.Add(otherVerb);
      m_Verbs = new WebPartVerbCollection(verbsList);
      return m_Verbs;
    }
    return m_Verbs;
  }
}

' This property implements the IWebActionable interface.
ReadOnly Property Verbs() As WebPartVerbCollection _
  Implements IWebActionable.Verbs
  Get
    If (m_Verbs Is Nothing) Then
      Dim verbsList As New ArrayList()
      Dim onlyVerb As New WebPartVerb _
        ("customVerb1", New WebPartEventHandler(AddressOf IncrementVerbCounterClicks))
      onlyVerb.Text = "My Verb"
      onlyVerb.Description = "VerbTooltip"
      onlyVerb.Visible = True
      onlyVerb.Enabled = True
      verbsList.Add(onlyVerb)
      Dim otherVerb As New WebPartVerb _
        ("customVerb2", New WebPartEventHandler(AddressOf IncrementVerbCounterClicks))
      otherVerb.Text = "My other Verb"
      otherVerb.Description = "Other VerbTooltip"
      otherVerb.Visible = True
      otherVerb.Enabled = True
      verbsList.Add(otherVerb)
      m_Verbs = New WebPartVerbCollection(verbsList)
    End If
    Return m_Verbs
  End Get
End Property

注解

属性 Verbs 引用自定义谓词的集合， (如果添加到谓词菜单的标头或其他服务器控件中的任何 WebPart) 。 该Verbs集合不包含对Web 部件控件集提供的标准WebPartVerb对象的引用，例如CloseVerb、DeleteVerb、EditVerb、RestoreVerb或MinimizeVerb。

想要将自定义谓词添加到派生自类的 WebPart 自定义控件的开发人员只需重写 Verbs 类实现的属性 WebPart 。

想要将自定义谓词添加到用户控件或不是WebPart控件的自定义控件的开发人员必须通过提供属性的Verbs实现来实现IWebActionable接口。
