DataBindingHandlerAttribute Class


Specifies a design-time class that performs data binding of controls within a designer. This class cannot be inherited.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)


Public NotInheritable Class DataBindingHandlerAttribute
	Inherits Attribute


Initializes a new instance of the DataBindingHandlerAttribute class using no parameters. This is the default constructor.


Initializes a new instance of the DataBindingHandlerAttribute class with the specified type name.


Initializes a new instance of the DataBindingHandlerAttribute class of the specified Type.


Gets the type name of the data-binding handler.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Determines whether two object instances are equal.(Overrides Attribute.Equals(Object).)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns the hash code for this instance.(Overrides Attribute.GetHashCode().)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)


Defines the default attribute for the DataBindingHandlerAttribute class.

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The following code example defines a data-binding handler, named MyDataBindingHandler, to be used by the designer in editing mode. On exiting the editing mode, the Text property value is displayed.

Namespace CustomControls

  <DataBindingHandler(GetType(MyDataBindingHandler)), ToolboxData("<{0}:MyLabel runat=server></{0}:MyLabel>")>  _
    Public Class MyLabel
      Inherits Label

      Public Sub New()
        'Insert your code here.
      End Sub 'NewNew

    End Class 'MyLabel

    Public Class MyDataBindingHandler
      Inherits DataBindingHandler

      Public Overrides Sub DataBindControl(host As IDesignerHost, control As Control)
         CType(control, Label).Text = "Added by data binding handler."
      End Sub 'DataBindControl

    End Class 'MyDataBindingHandler
