Raises the Select event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

protected virtual void OnSelect (
	EventArgs e
)
protected void OnSelect (
	EventArgs e
)
protected function OnSelect (
	e : EventArgs
)

Parameters

e

An EventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

Notes to Inheritors When overriding OnSelect in a derived class, be sure to call the base class's OnSelect method.

The following code example demonstrates how to use the Select event of the MenuItem class to assign help text to a StatusBarPanel of a StatusBar control. This example requires that MenuItem objects named menuOpen, menuSave, and menuExit are added to a MainMenu control on a form. The example also requires that a StatusBar control, named statusBar1 has been added to the form. The StatusBar control should contain a StatusBarPanel.

private void MenuSelected(object sender, System.EventArgs e)
{
   if (sender == menuOpen)
      statusBar1.Panels[0].Text = "Opens a file to edit";
   else if(sender == menuSave)
      statusBar1.Panels[0].Text = "Saves the current file";
   else if(sender == menuExit)
      statusBar1.Panels[0].Text = "Exits the application";
   else
      statusBar1.Panels[0].Text = "Ready";
}

private void MenuSelected(Object sender, System.EventArgs e)
{
    if (sender.Equals(menuOpen)) {
        statusBar1.get_Panels().get_Item(0).
            set_Text("Opens a file to edit");
    }
    else {
        if (sender.Equals(menuSave)) {
            statusBar1.get_Panels().get_Item(0).
                set_Text("Saves the current file");
        }
        else {
            if (sender.Equals(menuExit)) {
                statusBar1.get_Panels().get_Item(0).
                    set_Text("Exits the application");
            }
            else {
                statusBar1.get_Panels().get_Item(0).set_Text("Ready");
            }
        } 
    }
} //MenuSelected
