Raises the Leave event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.Notes to Inheritors
When overriding in a derived class, be sure to call the base class's method so that registered delegates receive the event.
The following code example uses the Leave event to reset a control to its former state.
Private Sub textBox1_Enter(sender As Object, e As System.EventArgs) Handles textBox1.Enter ' If the TextBox contains text, change its foreground and background colors. If textBox1.Text <> [String].Empty Then textBox1.ForeColor = Color.Red textBox1.BackColor = Color.Black ' Move the selection pointer to the end of the text of the control. textBox1.Select(textBox1.Text.Length, 0) End If End Sub 'textBox1_Enter Private Sub textBox1_Leave(sender As Object, e As System.EventArgs) Handles textBox1.Leave ' Reset the colors and selection of the TextBox after focus is lost. textBox1.ForeColor = Color.Black textBox1.BackColor = Color.White textBox1.Select(0, 0) End Sub 'textBox1_Leave End Class 'Form1
