Behavior Class
Represents the Behavior objects that are managed by a BehaviorService.
Assembly: System.Design (in System.Design.dll)
The Behavior type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Behavior() | Initializes a new instance of the Behavior class. |
![]() | Behavior(Boolean, BehaviorService) | Initializes a new instance of the Behavior class with the given BehaviorService. |
| Name | Description | |
|---|---|---|
![]() | Cursor | Gets the cursor that should be displayed for this behavior. |
![]() | DisableAllCommands | Gets a value indicating whether MenuCommand objects should be disabled. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | FindCommand | Intercepts commands. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnDragDrop | Permits custom drag-and-drop behavior. |
![]() | OnDragEnter | Permits custom drag-enter behavior. |
![]() | OnDragLeave | Permits custom drag-leave behavior. |
![]() | OnDragOver | Permits custom drag-over behavior. |
![]() | OnGiveFeedback | Permits custom drag-and-drop feedback behavior. |
![]() | OnLoseCapture | Called by the adorner window when it loses mouse capture. |
![]() | OnMouseDoubleClick | Called when any double-click message enters the adorner window of the BehaviorService. |
![]() | OnMouseDown | Called when any mouse-down message enters the adorner window of the BehaviorService. |
![]() | OnMouseEnter | Called when any mouse-enter message enters the adorner window of the BehaviorService. |
![]() | OnMouseHover | Called when any mouse-hover message enters the adorner window of the BehaviorService. |
![]() | OnMouseLeave | Called when any mouse-leave message enters the adorner window of the BehaviorService. |
![]() | OnMouseMove | Called when any mouse-move message enters the adorner window of the BehaviorService. |
![]() | OnMouseUp | Called when any mouse-up message enters the adorner window of the BehaviorService. |
![]() | OnQueryContinueDrag | Sends this drag-and-drop event from the adorner window to the appropriate Behavior or hit-tested Glyph. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
This class can be extended to develop any type of user interface behavior, including selection, drag, and resize behaviors.

Note |
|---|
Your Behavior type must be associated with a Glyph type. Glyph-independent behaviors are not supported. |
The following code example demonstrates how to create your own class based on the Behavior class that responds to user clicks. This code example is part of a larger example provided for the BehaviorService class.
// By providing our own behavior we can do something
// interesting when the user clicks or manipulates our glyph.
public ref class DemoBehavior : public Behavior
{
public:
bool OnMouseUp(Glyph^ g, MouseButtons^ button)
{
MessageBox::Show("Hey, you clicked the mouse here");
// indicating we processed this event.
return true;
}
};
public ref class DemoGlyph : public Glyph
{
Control^ control;
BehaviorService^ behavior;
public:
DemoGlyph(BehaviorService^ behavior, Control^ control):
Glyph(gcnew BehaviorServiceSample::DemoBehavior)
{
this->behavior = behavior;
this->control = control;
}
public:
virtual property Rectangle Bounds
{
Rectangle get() override
{
// Create a glyph that is 10x10 and sitting
// in the middle of the control. Glyph coordinates
// are in adorner window coordinates, so we must map
// using the behavior service.
Point edge = behavior->ControlToAdornerWindow(control);
Size size = control->Size;
Point center = Point(edge.X + (size.Width / 2),
edge.Y + (size.Height / 2));
Rectangle bounds = Rectangle(center.X - 5,
center.Y - 5, 10, 10);
return bounds;
}
}
public:
virtual Cursor^ GetHitTest(Point p) override
{
// GetHitTest is called to see if the point is
// within this glyph. This gives us a chance to decide
// what cursor to show. Returning null from here means
// the mouse pointer is not currently inside of the
// glyph. Returning a valid cursor here indicates the
// pointer is inside the glyph, and also enables our
// Behavior property as the active behavior.
if (Bounds.Contains(p))
{
return Cursors::Hand;
}
return nullptr;
}
public:
virtual void Paint(PaintEventArgs^ pe) override
{
// Draw our glyph. Our's is simple: a blue ellipse.
pe->Graphics->FillEllipse(Brushes::Blue, Bounds);
}
};
