ButtonPartClass Class

An instance of the ButtonPartClass class represents a button part.

Cells can contain one or several push buttons (instances of the ButtonPartClass). Each button can operate independently with its own attributes and properties.

A push button can contain an image or text (not both).

The Action event can be used to handle a button click.

If the Action event is used, the ItemClick event is not raised.

Constructors

ButtonPartClass

Initializes a new instance of the ButtonPartClass class.

Properties

	Angle	Defines the rotation of the part.
	Appearance	Defines the button appearance.
	Enabled	Defines whether the button is enabled.
	Font	Defines the button's text font.
	ForeColor	Defines the button's text color.
	HAlign	Defines the horizontal alignment within the part's available space.
	Image	Defines the button image.
	Orientation	Returns the orientation of parts within a cell. This is defined by the cell or the owner of the cell.
	PartAlignment	Defines the part alignment of this part relative to its container and other parts.
	PartOwner	Returns the owner of the part, usually an object derived from CellBaseClass.
	Pressed	Defines whether the button is currently pressed.
	TagObject	Defines application-specific data.
	TagString	Defines an application-specific string.
	Text	Defines the button text.
	Toggle	Defines whether the button is a toggle button.
	VAlign	Defines the vertical alignment within the part's available space.
	VisibleAppearance	Returns the visibility status of the part.

Methods

	CalcRotatedSize	Calculates the size of the smallest rectangle that can contain the rotated rectangle of a given size, based on the part's GenericPartClass.Angle property.
	CalcSize	Calculates the size of the part.
	CalcUnrotatedBaseWidth	Calculates the actual width of the part, based on the width of the rotated part's containing rectangle.
	ConsiderForOutline	Defines whether the part is considered when calculating the outline rectangle of a cell.
	Copy	Creates an identical copy of the part.
	CopyPart	Copies information from one part to another.
	Equals	Determines whether the specified object is equal to the current object.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
	GetHashCode	Serves as the default hash function.
	GetType	Gets the Type of the current instance.
	GetVisible	Returns the current visibility status of a part, based on the part's GenericPartClass.VisibleAppearance property.
	MemberwiseClone	Creates a shallow copy of the current Object.
	OnContentChanged	Called when the contents of the part changed.
	ReferenceEquals	Determines whether the specified Object instances are the same instance.
	StrategyRoutine	Used to perform various actions the part supports, like rendering the part, hit-testing, determining its position and responding to mouse button clicks.
	ToString	Returns a string that represents the current object.

Events

Action

Occurs when a part's action is triggered by the user.

Examples

C#

            // Add a progressbar to the first cell
            ProgressBarPartClass pbp = new ProgressBarPartClass(0, 50, 25, 100, 12, GadgetAppearanceEnum.ThemedSystem,
                            Color.Red, Color.White, System.Drawing.Drawing2D.LinearGradientMode.Vertical);
            pbp.PartAlignment = PartAlignmentEnum.EntireArea;
            pbp.Appearance = GadgetAppearanceEnum.System;
            item.Cells[0].Parts.Add(pbp);

            // Add a button to the second cell
            ButtonPartClass bp = new ButtonPartClass(false, HAlignmentOptionalEnum.Default, VAlignmentOptionalEnum.Default,
                        true, false, GadgetAppearanceEnum.ThemedSystem, null, "Click Me", null, Color.Red);
            bp.Action += new GenericPartClass.ActionEventHandler(bp_Action);
            item.Cells[1].Parts.Add(bp);

            // Add text to the third cell
            cell = item.Cells[2];
            cell.Text = "Sample Text";
