public int Top { get; set; }
/** @property */

Property Value

An Int32 representing the distance, in pixels, between the bottom edge of the control and the top edge of its container's client area.

The Top property value is equivalent to the Point.Y property of the Location property value of the control.

Changes made to the Height and Top property values cause the Bottom property value of the control to change.

The following code example creates three Button controls on a form and sets their size and location by using the various size-related and location-related properties. This example requires that you have a Form that has a width and height of at least 300 pixels.

// Create three buttons and place them on a form using 
// several size and location related properties. 
private void AddOKCancelButtons()
{
   // Set the button size and location using 
   // the Size and Location properties.
   Button buttonOK = new Button();
   buttonOK.Location = new Point(136,248);
   buttonOK.Size = new Size(75,25);
   // Set the Text property and make the 
   // button the form's default button. 
   buttonOK.Text = "&OK";
   this.AcceptButton = buttonOK;

   // Set the button size and location using the Top, 
   // Left, Width, and Height properties.
   Button buttonCancel = new Button();
   buttonCancel.Top = buttonOK.Top;
   buttonCancel.Left = buttonOK.Right + 5;
   buttonCancel.Width = buttonOK.Width;
   buttonCancel.Height = buttonOK.Height;
   // Set the Text property and make the 
   // button the form's cancel button.
   buttonCancel.Text = "&Cancel";
   this.CancelButton = buttonCancel;

   // Set the button size and location using 
   // the Bounds property.
   Button buttonHelp = new Button();
   buttonHelp.Bounds = new Rectangle(10,10, 75, 25);
   // Set the Text property of the button.
   buttonHelp.Text = "&Help";

   // Add the buttons to the form.
   this.Controls.AddRange(new Control[] {buttonOK, buttonCancel, buttonHelp} );
}

// Create three buttons and place them on a form using 
// several size and location related properties. 
private void AddOKCancelButtons()
{
    // Set the button size and location using 
    // the Size and Location properties.
    Button buttonOK = new Button();
    buttonOK.set_Location(new Point(136, 248));
    buttonOK.set_Size(new Size(75, 25));
    // Set the Text property and make the 
    // button the form's default button. 
    buttonOK.set_Text("&OK");
    this.set_AcceptButton(buttonOK);
    // Set the button size and location using the Top, 
    // Left, Width, and Height properties.
    Button buttonCancel = new Button();
    buttonCancel.set_Top(buttonOK.get_Top());
    buttonCancel.set_Left(buttonOK.get_Right() + 5);
    buttonCancel.set_Width(buttonOK.get_Width());
    buttonCancel.set_Height(buttonOK.get_Height());
    // Set the Text property and make the 
    // button the form's cancel button.
    buttonCancel.set_Text("&Cancel");
    this.set_CancelButton(buttonCancel);
    // Set the button size and location using 
    // the Bounds property.
    Button buttonHelp = new Button();
    buttonHelp.set_Bounds(new Rectangle(10, 10, 75, 25));
    // Set the Text property of the button.
    buttonHelp.set_Text("&Help");
    // Add the buttons to the form.
    this.get_Controls().AddRange(new Control[] { buttonOK, buttonCancel,
        buttonHelp });
} //AddOKCancelButtons
