ToolStripItem.MouseEnter Event


Occurs when the mouse pointer enters the item.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event EventHandler MouseEnter

Mouse events occur in the following order:

  1. MouseEnter

  2. MouseMove

  3. MouseHover or MouseDown

  4. MouseUp

  5. MouseLeave

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MouseEnter event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripItem, such as a ToolStripButton or ToolStripMenuItem. Then name the instance ToolStripItem1 and ensure that the event handler is associated with the MouseEnter event.

private void ToolStripItem1_MouseEnter(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripItem.MouseEnter event.");
