Properties

Name Type Description
AutoSize bool Gets or sets a value indicating whether the control is resized in accordance with its contents
Background Color Gets or sets a brush that describes the background of a control
BackgroundIsTransparent bool Gets a value indicating whether the Background has Color.NotSet
Bounds Rect Gets the size and location of the control including its nonclient elements, in points, relative to the parent control
DesiredSize Size Gets the size that this element computed during the measure pass of the layout process
DisabledBackground Color Gets or sets a value to display of background when the control is disabled
DisabledForeground Color Gets or sets a value to display of text color when the control is disabled
DrawingContext IDrawingContext Gets a value of the drawing context
FocusBackground Color Focused component background color
FocusForeground Color Focused component text color
Foreground Color Gets or sets a brush that describes the text of a control
ForegroundIsTransparent bool Gets a value indicating whether the Foreground has Color.NotSet
Height int? Gets or sets the height of the control
Id long Gets a value of the control's identifier
IsDisabled bool Gets or sets a value indicating whether the control cannot respond to user interaction
IsFocus bool Gets or sets focus value of component
IsMeasureValid bool Gets a value indicating whether component sizing was performed
IsVisualValid bool Gets a value indicating whether the component is being re-rendered
Location Point Gets or sets the coordinates of the upper-left corner of the control relative to the upper-left corner of its container
Margin Thickness Gets or sets the outer margin of an element
Padding Thickness Gets or sets a Thickness value that describes the amount of space between a control and its child element
Parent ContentControl Gets or sets the parent container of the control
TabIndex int Gets or sets the sequence for moving the TAB key between the controls inside the container

Tag object Gets or sets the object that contains data about the control
Width int? Gets or sets the width of the control

Methods

Syntax Description
Arrange(Rect) Positions child elements and determines a size for a Control. Parent elements call this method from their Arrange(Rect) implementation to form a recursive layout update
CanFocus() Indicates whether component focus can be set
InputAction(ConsoleKeyInfo) Handles a keystroke
InvalidateMeasure() Invalidates the measurement state (layout) for the element
InvalidateMeasureIfAutoSize() Invalidates the measurement state (layout) for the element if AutoSize property is true otherwise invalidates the rendering of the element
InvalidateVisual() Invalidates the rendering of the element, and forces a complete new layout pass. OnRender(IDrawingContext) is called after the layout cycle is completed
Measure(Size) Updates DesiredSize of a Control. Parent elements call this method from their own Measure(Size) implementations to form a recursive layout update
OnRender(IDrawingContext) Filling a pseudographics drawing context
ParentWindow() Gets the form the control is in
SetFocus() Sets input focus to current item
SetStyle(Action) Defines actions with an element style
