定义

命名空间:

System.Web.UI.Adapters

程序集:

System.Web.dll

获取对附加了此控件适配器的控件的引用。

protected:
 property System::Web::UI::Control ^ Control { System::Web::UI::Control ^ get(); };

[System.ComponentModel.Browsable(false)]
protected System.Web.UI.Control Control { get; }

[<System.ComponentModel.Browsable(false)>]
member this.Control : System.Web.UI.Control

Protected ReadOnly Property Control As Control

属性值

Control

附加此 Control 的 ControlAdapter。

属性

BrowsableAttribute

示例

下面的代码示例演示如何从 Control 类派生自定义控件，然后创建从 ControlAdapter 类继承的相应适配器。 适配器重写 属性， Control 并返回对 控件的强类型引用。

#using <System.Web.Mobile.dll>
#using <System.dll>
#using <System.Web.dll>

using namespace System;
using namespace System::Web::UI;
using namespace System::Web::UI::Adapters;
using namespace System::Web::UI::WebControls;

public ref class CustomControl: public Control{};

public ref class CustomControlAdapter: public ControlAdapter
{
public:

   property System::Web::UI::Control^ Control 
   {
      // Return a strongly-typed reference to your custom control.
      System::Web::UI::Control^ get()
      {
         return (CustomControl^)ControlAdapter::Control;
      }
   }
   // Override other ControlAdapter members, as necessary. 
};

using System;
using System.Web.UI;
using System.Web.UI.Adapters;
using System.Web.UI.WebControls;

public class CustomControl : Control
{
    // Add your custom control code.
}

public class CustomControlAdapter : ControlAdapter
{
    // Return a strongly-typed reference to your custom control.
    public new CustomControl Control
    {
        get
        {
            return (CustomControl)base.Control;
        }

        // Override other ControlAdapter members, as necessary. 
    }
}

Imports System.Web.UI
Imports System.Web.UI.Adapters
Imports System.Web.UI.WebControls

Public Class CustomControl
    Inherits Control

    ' Add your custom control code.

End Class

Public Class CustomControlAdapter
    Inherits ControlAdapter

    ' Return a strongly-typed reference to your custom control.
    Public Shadows ReadOnly Property Control() As CustomControl
        Get
            Return CType(MyBase.Control, CustomControl)
        End Get
    End Property

    ' Override other ControlAdapter member as necessary. 

End Class

注解

当派生的控件适配器附加到控件时，.NET Framework调用某些适配器成员而不是控件成员。

继承者说明

从 ControlAdapter 类继承时，至少应实现 属性 Control 以返回控件的强类型实例，如示例部分所示。
