Form.Load (Evento)
Se produce antes de que se muestre un formulario por primera vez.

Espacio de nombres: System.Windows.Forms
Ensamblado: System.Windows.Forms (en system.windows.forms.dll)

Visual Basic (Declaración)
Public Event Load As EventHandler
Visual Basic (Uso)
Dim instance As Form
Dim handler As EventHandler

AddHandler instance.Load, handler
C#
public event EventHandler Load
C++
public:
event EventHandler^ Load {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}
J#
/** @event */
public void add_Load (EventHandler value)

/** @event */
public void remove_Load (EventHandler value)
JScript
En JScript, se pueden controlar los eventos que define una clase, pero no se pueden definir unos propios.
XAML
No aplicable.

Este evento se puede usar para realizar tareas tales como la asignación de los recursos que utiliza el formulario.

Para obtener más información sobre control de eventos, vea Utilizar eventos.

NotaNota:

Cuando proporcione su propia implementación de Load, asegúrese de llamar a la implementación del método base del controlador de eventos Load del formulario base. De no hacerlo, puede que algunas características del formulario no funcionen correctamente, como el ajuste automático de tamaño. Para obtener más información sobre cómo llamar a un método base, vea Trabajar con tipos base.

En el siguiente ejemplo de código se muestra cómo usar los miembros SetDesktopLocation, Load, Activated y Activate. Para ejecutar el ejemplo, pegue el código siguiente en un formulario denominado Form1 que contenga un Button denominado Button1, y dos controles Label denominados Label1 y Label2.

Visual Basic
Shared x As Integer = 200
Shared y As Integer = 200

Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    ' Create a new Form1 and set its Visible property to true.
    Dim form2 As New Form1
    form2.Visible = True

    ' Set the new form's desktop location so it appears below and 
    ' to the right of the current form.
    form2.SetDesktopLocation(x, y)
    x += 30
    y += 30

    ' Keep the current form active by calling the Activate method.
    Me.Activate()
    Me.Button1.Enabled = False
End Sub



' Updates the label text to reflect the current values of x and y, 
' which was were incremented in the Button1 control's click event.
Private Sub Form1_Activated(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Activated
    Label1.Text = "x: " & x & " y: " & y
    Label2.Text = "Number of forms currently open: " & count
End Sub

Shared count As Integer = 0

Private Sub Form1_Closed(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Closed
    count -= 1
End Sub

Private Sub Form1_Load(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
    count += 1
End Sub
