Definition

Namespace:

System.ComponentModel

Assembly:

System.ComponentModel.TypeConverter.dll

Initializes a new instance of the PropertyTabAttribute class.

Overloads

PropertyTabAttribute()	Initializes a new instance of the PropertyTabAttribute class.
PropertyTabAttribute(String)	Initializes a new instance of the PropertyTabAttribute class using the specified tab class name.
PropertyTabAttribute(Type)	Initializes a new instance of the PropertyTabAttribute class using the specified type of tab.
PropertyTabAttribute(String, PropertyTabScope)	Initializes a new instance of the PropertyTabAttribute class using the specified tab class name and tab scope.

PropertyTabAttribute()

Source:

PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class.

public:
 PropertyTabAttribute();

public PropertyTabAttribute ();

Public Sub New ()

Remarks

This is a parameterless constructor that creates an uninitialized PropertyTabAttribute. This constructor can be used to derive from this attribute and specify multiple tab types by calling InitializeArrays.

• InitializeArrays(String[], PropertyTabScope[])

PropertyTabAttribute(String)

Source:

PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class using the specified tab class name.

public:
 PropertyTabAttribute(System::String ^ tabClassName);

public PropertyTabAttribute (string tabClassName);

new System.ComponentModel.PropertyTabAttribute : string -> System.ComponentModel.PropertyTabAttribute

Public Sub New (tabClassName As String)

Parameters

tabClassName

String

The assembly qualified name of the type of tab to create. For an example of this format convention, see AssemblyQualifiedName.

PropertyTabAttribute(Type)

Source:

PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class using the specified type of tab.

public:
 PropertyTabAttribute(Type ^ tabClass);

public PropertyTabAttribute (Type tabClass);

new System.ComponentModel.PropertyTabAttribute : Type -> System.ComponentModel.PropertyTabAttribute

Public Sub New (tabClass As Type)

Parameters

tabClass

Type

The type of tab to create.

PropertyTabAttribute(String, PropertyTabScope)

Source:

PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class using the specified tab class name and tab scope.

public:
 PropertyTabAttribute(System::String ^ tabClassName, System::ComponentModel::PropertyTabScope tabScope);

public PropertyTabAttribute (string tabClassName, System.ComponentModel.PropertyTabScope tabScope);

new System.ComponentModel.PropertyTabAttribute : string * System.ComponentModel.PropertyTabScope -> System.ComponentModel.PropertyTabAttribute

Public Sub New (tabClassName As String, tabScope As PropertyTabScope)

Parameters

tabClassName

String

The assembly qualified name of the type of tab to create. For an example of this format convention, see AssemblyQualifiedName.

tabScope

PropertyTabScope

A PropertyTabScope that indicates the scope of this tab. If the scope is Component, it is shown only for components with the corresponding PropertyTabAttribute. If it is Document, it is shown for all components on the document.

Exceptions

ArgumentException

tabScope is not Document or Component.

PropertyTabAttribute(Type, PropertyTabScope)

Source:

PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class using the specified type of tab and tab scope.

public:
 PropertyTabAttribute(Type ^ tabClass, System::ComponentModel::PropertyTabScope tabScope);

public PropertyTabAttribute (Type tabClass, System.ComponentModel.PropertyTabScope tabScope);

new System.ComponentModel.PropertyTabAttribute : Type * System.ComponentModel.PropertyTabScope -> System.ComponentModel.PropertyTabAttribute

Public Sub New (tabClass As Type, tabScope As PropertyTabScope)

Parameters

tabClass

Type

The type of tab to create.

tabScope

PropertyTabScope

A PropertyTabScope that indicates the scope of this tab. If the scope is Component, it is shown only for components with the corresponding PropertyTabAttribute. If it is Document, it is shown for all components on the document.

Exceptions

ArgumentException

tabScope is not Document or Component.
