示例

下面的代码示例演示了对控件的属性的使用RestoreVerbWebPartZone。 若要使代码示例正常工作，需要属性的“示例”部分中 HelpVerb 的所有代码。

代码示例的以下部分来自分部类，并包含用于切换还原谓词是启用或禁用还是禁用还原谓词的代码。

protected void CheckBoxList1_SelectedItemIndexChanged(Object sender, EventArgs e)
{
  foreach (ListItem item in CheckBoxList1.Items)
  {
    WebPartVerb theVerb;
    switch (item.Value)
    {
      case "close":
        theVerb = WebPartZone1.CloseVerb;
        break;
      case "export":
        theVerb = WebPartZone1.ExportVerb;
        break;
      case "delete":
        theVerb = WebPartZone1.DeleteVerb;
        break;
      case "minimize":
        theVerb = WebPartZone1.MinimizeVerb;
        break;
      case "restore":
        theVerb = WebPartZone1.RestoreVerb;
        break;
      default:
        theVerb = null;
        break;
    }

    if (item.Selected)
      theVerb.Enabled = true;
    else
      theVerb.Enabled = false;
  }
}

Protected Sub CheckBoxList1_SelectedItemIndexChanged(ByVal sender As [Object], ByVal e As EventArgs)
  Dim item As ListItem
  For Each item In CheckBoxList1.Items
    Dim theVerb As WebPartVerb
    Select Case item.Value
      Case "close"
        theVerb = WebPartZone1.CloseVerb
      Case "export"
        theVerb = WebPartZone1.ExportVerb
      Case "delete"
        theVerb = WebPartZone1.DeleteVerb
      Case "minimize"
        theVerb = WebPartZone1.MinimizeVerb
      Case "restore"
        theVerb = WebPartZone1.RestoreVerb
      Case Else
        theVerb = Nothing
    End Select

    If item.Selected Then
      theVerb.Enabled = True
    Else
      theVerb.Enabled = False
    End If
  Next item

End Sub

代码示例的另一部分是承载自定义 WebPart 控件的网页，其中包含用户界面 (UI) 。 请注意，区域中的声明性 <RestoreVerb> 元素设置属性文本的值 Description ，当用户将鼠标指针放在谓词菜单中时，该文本显示为工具提示。

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

在浏览器中加载页面后，将页面切换到目录显示模式，并将控件添加到 TextDisplayWebPart 页面（如果尚未添加）。 使用最小化谓词最小化控件，并注意还原谓词变为可见。 可以使用复选框来启用和禁用还原谓词。

注解

当控件最小化时，属性引用 RestoreVerb 的还原谓词将显示在区域中每个 WebPart 控件的谓词菜单中。 该谓词在所有页面显示模式的菜单中显示。

在控件以前最小化后，还原控件会将其扩展回其正常大小。
