Namespace: System.Windows.Controls.Primitives
Assembly: System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Property ClickMode As ClickMode

public ClickMode ClickMode { get; set; }

XAML Values

Property Value

Type: System.Windows.Controls.ClickMode
When the Click event occurs. The default value is ClickMode.Release.

Remarks

Dependency property identifier field: ClickModeProperty

Use this property to set what type of user interaction is required to raise a Click event. When a button's click mode is Hover, the Click event cannot be raised by using the keyboard.

Examples

The following example shows three buttons that respond to clicks in three different ways based on their ClickMode property value.

Hover - When the mouse pointer hovers over the first button, the foreground color of the button changes.
Press - When the left mouse button is pressed while over the second button, the foreground color of the button changes.
Release - When the mouse button is pressed and released while over the third button, the button resets the foreground color of the other two buttons to their original color.
