Occurs when the mouse pointer rests on the control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
A typical use of is to display a tool tip when the mouse pauses on a control within a specified area around the control (the "hover rectangle"). The pause required for this event to be raised is specified in milliseconds by the MouseHoverTime property.
Mouse events occur in the following order:
The following events are not raised for the TabControl class unless there is at least one TabPage in the TabControl.TabPages collection: Click, DoubleClick, MouseDown, MouseUp, , MouseEnter, MouseLeave and MouseMove. If there is at least one TabPage in the collection, and the user interacts with the tab control's header (where the TabPage names appear), the TabControl raises the appropriate event. However, if the user interaction is within the client area of the tab page, the TabPage raises the appropriate event.

The following code example demonstrates using different mouse events to draw the path of the mouse on a Panel. A line segment is added to the GraphicsPath for each MouseMove and MouseDown events that occur. To update the graphics, the Invalidate method is called for the Panel on each MouseDown and MouseUp event. In addition, the graphic path is scrolled up or down when the MouseWheel event occurs. Additional mouse events, like , are identified on screen as well. Also displayed on the screen is additional information about the mouse from the SystemInformation class.
