CustomComponentViewHandlerAttribute Class

Notifies the data flow designer at design time that the user interface of the component will manage the component viewer by itself.

Namespace:  Microsoft.SqlServer.Dts.Pipeline.Design
Assembly:  Microsoft.SqlServer.Dts.Design (in Microsoft.SqlServer.Dts.Design.dll)

Syntax

'Declaration
<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple := False)> _
Public NotInheritable Class CustomComponentViewHandlerAttribute _
    Inherits Attribute
'Usage
Dim instance As CustomComponentViewHandlerAttribute

[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false)]
public sealed class CustomComponentViewHandlerAttribute : Attribute

[AttributeUsageAttribute(AttributeTargets::Class, AllowMultiple = false)]
public ref class CustomComponentViewHandlerAttribute sealed : public Attribute

[<SealedAttribute>]
[<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false)>]
type CustomComponentViewHandlerAttribute =  
    class
        inherit Attribute
    end

public final class CustomComponentViewHandlerAttribute extends Attribute

Remarks

This attribute is typically used by components where design-time modifications have side effects outside the component itself and where the component manages other components in the data flow. For example, the Slowly Changing Dimension Transformation creates an entire sequence of data flow components and may also delete other objects.

Examples

The following sample shows the CustomComponentViewHandlerAttribute attribute applied to a class.

[CustomComponentViewHandler]
public class MyComponentUI
{
   ...
]

<CustomComponentViewHandler> _
Public Class MyComponentUI
  ...
End Class
