PropertyGridEditorPart Web 服务器控件声明性语法

2011-08-12

提供一个编辑器控件，最终用户可以通过该控件编辑相关联的 WebPart 或服务器控件上的自定义属性。此类不能被继承。

<asp:PropertyGridEditorPart
    AccessKey="string"
    BackColor="color name|#dddddd"
    BackImageUrl="uri"
    BorderColor="color name|#dddddd"
    BorderStyle="NotSet|None|Dotted|Dashed|Solid|Double|Groove|Ridge|
                 Inset|Outset"
    BorderWidth="size"
    ChromeState="Normal|Minimized"
    ChromeType="Default|TitleAndBorder|None|TitleOnly|BorderOnly"
    CssClass="string"
    DefaultButton="string"
    Description="string"
    Direction="NotSet|LeftToRight|RightToLeft"
    Enabled="True|False"
    EnableTheming="True|False"
    EnableViewState="True|False"
    Font-Bold="True|False"
    Font-Italic="True|False"
    Font-Names="string"
    Font-Overline="True|False"
    Font-Size="string|Smaller|Larger|XX-Small|X-Small|Small|Medium|
               Large|X-Large|XX-Large"
    Font-Strikeout="True|False"
    Font-Underline="True|False"
    ForeColor="color name|#dddddd"
    GroupingText="string"
    Height="size"
    HorizontalAlign="NotSet|Left|Center|Right|Justify"
    ID="string"
    OnDataBinding="DataBinding event handler"
    OnDisposed="Disposed event handler"
    OnInit="Init event handler"
    OnLoad="Load event handler"
    OnPreRender="PreRender event handler"
    OnUnload="Unload event handler"
    runat="server"
    ScrollBars="None|Horizontal|Vertical|Both|Auto"
    SkinID="string"
    Style="string"
    TabIndex="integer"
    Title="string"
    ToolTip="string"
    Visible="True|False"
    Width="size"
    Wrap="True|False"
/>

备注

PropertyGridEditorPart 提供了一个通用用户界面 (UI)，使用户可以在放在 WebPartZoneBase 区域中的 WebPart 和服务器控件上编辑自定义属性。相比之下，另外的 EditorPart 控件（如 AppearanceEditorPart 和 BehaviorEditorPart 控件）只编辑 WebPart 类的现有的、面向用户界面的属性。

有关 PropertyGridEditorPart 和 Web 部件控件的更多信息，请参见 ASP.NET Web 部件控件。

示例

下面的代码示例演示如何使用 PropertyGridEditorPart 控件。该网页以声明方式引用 EditorZone 控件，该控件具有一个 zonetemplate 子元素，其中以声明方式引用 PropertyGridEditorPart 控件。

有关在 @ Register 中引用的用户控件和自定义控件的定义，请参见 PropertyGridEditorPart 类概述中的“示例”。
