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)
public event EventHandler Load

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.

	static int x = 200;
	static int y = 200;

	private void Button1_Click(System.Object sender, 
		System.EventArgs e)
	{
		// Create a new Form1 and set its Visible property to true.
		Form1 form2 = 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. 
		this.Activate();
		this.Button1.Enabled = false;
	}
	


	// 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 void Form1_Activated(object sender, System.EventArgs e)
	{
		Label1.Text = "x: "+x+" y: "+y;
		Label2.Text = "Number of forms currently open: "+count;
	}

	static int count = 0;

	private void Form1_Closed(object sender, System.EventArgs e)
	{
		count -= 1;
	}

	private void Form1_Load(object sender, System.EventArgs e)
	{
		count += 1;
	}
