Controls in WPF (Windows Presentation Foundation)

Introduction

Windows Presentation Foundation (WPF) is a UI framework that creates desktop client applications. The WPF development platform supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding, and documents. This note focuses on the Controls aspect of WPF.

Buttons in WPF

Button Control

A Button in WPF is an interactive UI control that users can click to perform an action. The Button.BitmapEffect property allows you to set visual effects on the button, such as drop shadow, blur, or glow. For instance, you can use the DropShadowBitmapEffect to add a shadow effect to the button.

Example:

Button button = new Button();
DropShadowBitmapEffect myDropShadowEffect = new DropShadowBitmapEffect();
button.BitmapEffect = myDropShadowEffect;

RadioButton Control

RadioButtons can be grouped together to ensure that only one button in a group can be selected at a time. This can be achieved using the GroupName property.

Example:

RadioButton radioButton1 = new RadioButton();
RadioButton radioButton2 = new RadioButton();
radioButton1.GroupName = "group1";
radioButton2.GroupName = "group1";

ToggleButton Control

A ToggleButton is a button that can be toggled between two states. It is useful when you want a button that can be checked or unchecked like a checkbox but looks like a button.

Example:

ToggleButton toggleButton = new ToggleButton();
toggleButton.Content = "Toggle Button";

RepeatButton Control

The RepeatButton control is a button that raises click events repeatedly from the time it is pressed until it is released. This is useful for scenarios where a continuous action should be triggered while a button is being pressed.

Example:

RepeatButton repeatButton = new RepeatButton();
repeatButton.Content = "Repeat Button";
repeatButton.Click += (s, e) => {
    // Action to perform on click
};

Tooltip Control

A ToolTip can be attached to any FrameworkElement in WPF. It provides supplementary information about the function of the control. The tooltip text is set by the ToolTip property.

Example:

Button button = new Button();
button.ToolTip = "This is a tooltip";

GroupBox Control

A GroupBox is a control that provides a group box that can display a title and host content within a border. The title is set by the Header property.

Example:

GroupBox groupBox = new GroupBox();
groupBox.Header = "This is a group box";

ScrollViewer Control

A ScrollViewer is a control that provides a scrollable area that can contain other visible elements. It provides horizontal and vertical scroll bars.

Example:

ScrollViewer scrollViewer = new ScrollViewer();

Expander Control

An Expander control is like a collapsible group box. It includes a header and a collapsible content area. This is similar to the ComboBox in Windows Forms.

Example:

Expander expander = new Expander();
expander.Header = "Expander Header";
expander.Content = "Expander Content";

These are some of the basic controls in WPF which are used to build the user interface of a WPF application. There are many more controls available in WPF, and each provides a wide variety of properties that can be set to customize its behavior and appearance.
