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

property int Bottom {
	int get ();

Property Value

Type: System::Int32
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 value of this property is equal to the sum of the Top property value, and the Height property value.

The Bottom property is a read-only property. You can manipulate this property value by changing the value of the Top or Height properties or calling the SetBounds, SetBoundsCore, UpdateBounds, or SetClientSizeCore methods.

The following code example uses the Bottom property to define the lower limit of a TextBox control relative to the client area of the container.

   // This example demonstrates how to use the KeyUp event with the Help class to display 
   // pop-up style help to the user of the application. When the user presses F1, the Help 
   // class displays a pop-up window, similar to a ToolTip, near the control. This example assumes 
   // that a TextBox control, named textBox1, has been added to the form and its KeyUp 
   // event has been connected to this event handler method. 
   void textBox1_KeyUp( Object^ /*sender*/, System::Windows::Forms::KeyEventArgs^ e )

      // Determine whether the key entered is the F1 key. Display help if it is. 
      if ( e->KeyCode == Keys::F1 )

         // Display a pop-up help topic to assist the user.
         Help::ShowPopup( textBox1, "Enter your first name", Point(textBox1->Right,this->textBox1->Bottom) );
