Form.SetDesktopLocation Method

Sets the location of the form in desktop coordinates.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public void SetDesktopLocation(
	int x,
	int y


Type: System.Int32
The x-coordinate of the form's location.
Type: System.Int32
The y-coordinate of the form's location.

Desktop coordinates are based on the working area of the screen, which excludes the taskbar. You can use this method to position your form on the desktop. Since desktop coordinates are based on the working area of the form, you can use this method to ensure that your form is completely visible on the desktop. This method is intended to be used primarily for top-level forms; use the LayoutMdi method to position multiple-document interface (MDI) child forms.

The following code example demonstrates how to use the SetDesktopLocation, Load 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.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;
