Form.Load Event

Occurs before a form is displayed for the first time.

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

Visual Basic (Declaration)
Public Event Load As EventHandler
Visual Basic (Usage)
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
JScript supports the use of events, but not the declaration of new ones.

You can use this event to perform tasks such as allocating resources used by the form.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the SetDesktopLocation, Load, Activated, and Activate members. To run the example, paste the following code in a form called Form1 containing a Button called Button1 and two Label controls called Label1 and 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
C#
