Properties
Gets or sets a bool value indiciating whether the behavior applies NC theming to the form.
public abstract bool AllowTheming { get; set; }This rectangle represents the bottom border frame of a window.
public virtual Rectangle BottomBorderFrame { get; }This rectangle represents the bottomleft sizing corner of a window.
public virtual Rectangle BottomLeftResizeFrame { get; }This rectangle represents the bottom sizing frame of a window.
public virtual Rectangle BottomResizeFrame { get; }This rectangle represents the bottomright sizing corner of a window.
public virtual Rectangle BottomRightResizeFrame { get; }This rectangle represents the caption frame of a window.
public virtual Rectangle CaptionFrame { get; }Gets the rectangle that contains the form's caption text.
public abstract Rectangle CaptionTextBounds { get; }This rectangle represents the client rectangle of a window.
public virtual Rectangle ClientFrame { get; }Gets the current form CreateParams settings.
public virtual CreateParams CurrentFormParams { get; }Gets an integer value that determines the current Form state: Possible values come from the SIZE_RESTORED, SIZE_MAXIMIZED, SIZE_MINIMIZED win32 constants.
protected int CurrentFormState { get; }Gets or sets the form associated with this behavior. Used only in design-time. IMPORTANT: This property can be assigned only one time. An InvalidOperationException is thrown when the property is assigned more than once.
public RadFormControlBase Form { get; set; }Gets the MdiClient control of the Form. Returns null if the Form is not MdiContainer.
protected MdiClient FormMdiClient { get; }Gets the rectangle that contains the form's icon.
public abstract Rectangle IconBounds { get; }Gets a bool value that determines whether the Form's window state is maximized.
protected virtual bool IsMaximized { get; }Gets a boolean value showing whether a MDI child form is maximized.
protected virtual bool IsMdiChildMaximized { get; }Gets a boolean value determining whether there is a Menu in the Form.
protected bool IsMenuInForm { get; }Gets a bool value that determines whether the Form's window state is minimized.
protected virtual bool IsMinimized { get; }Gets a boolean value that determines whether the Form's window state is normal.
protected virtual bool IsNormal { get; }This rectangle represents the left border frame of a window.
public virtual Rectangle LeftBorderFrame { get; }This rectangle represents the left sizing frame of a window.
public virtual Rectangle LeftResizeFrame { get; }protected RadMenu MainMenuInForm { get; }Gets the maximized MDI child if any.
protected Form MaximizedMDIChild { get; }Gets the rectangle that contains the menu of the form.
public abstract Rectangle MenuBounds { get; }This rectangle represents the right border frame of a window.
public virtual Rectangle RightBorderFrame { get; }This rectangle represents the right sizing frame of a window.
public virtual Rectangle RightResizeFrame { get; }Gets the rectangle that contains the system buttons of the form.
public abstract Rectangle SystemButtonsBounds { get; }This rectangle represents the topleft sizing corner of a window.
public virtual Rectangle TopLeftResizeFrame { get; }This rectangle represents the top sizing frame of a window.
public virtual Rectangle TopResizeFrame { get; }This rectangle represents the topright sizing corner of a window.
public virtual Rectangle TopRightResizeFrame { get; }Methods
public override CreateParams CreateParams(CreateParams parameters)Overrides:
This method transforms screen coordinates into local coordinates.
This method returns the maximum available height according to the current position of the form in multi-monitor setup.
public override void InvalidateElement(RadElement element, Rectangle bounds)Overrides:
Invalidates the specified bounds in the non-client area of the form this behavior is associated with.
protected virtual void OnActiveMDIChildTextChanged()Occurs when a form is associated with the behavior.
protected override void OnFormAssociated()Overrides:
This event is fired when the WM_GETMINMAXINFO message is sent to the form.
protected virtual void OnGetMinMaxInfo(MinMaxInfo minMaxInfo)Contains information about the position, maximum/minimum size of the form etc. Can be modified to adjust the settings applied to the form.
This event is fired when the WM_NCPAINT message is sent to the form.
Fires when the window state of the form is changed. Uses the SIZE_* values to define the window states.
Paints an element on a specified graphics.
protected virtual void PaintElement(IGraphics graphics, Rectangle clipRectangle, VisualElement element)The Graphics object to paint on.
clipRectangleRectangleThe clipping rectangle.
elementVisualElementThe element to paint.
Immediately refreshes the whole non-client area of the form which this behavior is associated with.
protected virtual void RefreshNC()
