Form.MinimizeBox Property

Gets or sets a value indicating whether the Minimize button is displayed in the caption bar of the form.

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

public bool MinimizeBox { get; set; }
/** @property */
public boolean get_MinimizeBox ()

/** @property */
public void set_MinimizeBox (boolean value)

public function get MinimizeBox () : boolean

public function set MinimizeBox (value : boolean)

Property Value

true to display a Minimize button for the form; otherwise, false. The default is true.

A Minimize button enables users to minimize a window to an icon. To display a Minimize button, you must also set the form's FormBorderStyle property to FormBorderStyle.FixedSingle, FormBorderStyle.Sizable, FormBorderStyle.Fixed3D, or FormBorderStyle.FixedDialog.

NoteNote

Minimizing a form at run time generates a Resize event. The WindowState property reflects the current state of the window. If you set the WindowState property to FormWindowState.Minimized, the form is minimized independently of whatever settings are in effect for the MinimizeBox and FormBorderStyle properties.

The following code example creates a new instance of a Form and calls the ShowDialog method to display the form as a dialog box. The example sets the FormBorderStyle, AcceptButton, CancelButton, MinimizeBox, MaximizeBox, and StartPosition properties to change the appearance and functionality of the form to a dialog box. The example also uses the Add method of the form's Controls collection to add two Button controls. The example uses the HelpButton property to display a help button in the caption bar of the dialog box.

public void CreateMyForm()
{
   // Create a new instance of the form.
   Form form1 = new Form();
   // Create two buttons to use as the accept and cancel buttons.
   Button button1 = new Button ();
   Button button2 = new Button ();
  
   // Set the text of button1 to "OK".
   button1.Text = "OK";
   // Set the position of the button on the form.
   button1.Location = new Point (10, 10);
   // Set the text of button2 to "Cancel".
   button2.Text = "Cancel";
   // Set the position of the button based on the location of button1.
   button2.Location
      = new Point (button1.Left, button1.Height + button1.Top + 10);
   // Set the caption bar text of the form.   
   form1.Text = "My Dialog Box";
   // Display a help button on the form.
   form1.HelpButton = true;

   // Define the border style of the form to a dialog box.
   form1.FormBorderStyle = FormBorderStyle.FixedDialog;
   // Set the MaximizeBox to false to remove the maximize box.
   form1.MaximizeBox = false;
   // Set the MinimizeBox to false to remove the minimize box.
   form1.MinimizeBox = false;
   // Set the accept button of the form to button1.
   form1.AcceptButton = button1;
   // Set the cancel button of the form to button2.
   form1.CancelButton = button2;
   // Set the start position of the form to the center of the screen.
   form1.StartPosition = FormStartPosition.CenterScreen;
   
   // Add button1 to the form.
   form1.Controls.Add(button1);
   // Add button2 to the form.
   form1.Controls.Add(button2);
   
   // Display the form as a modal dialog box.
   form1.ShowDialog();
}

public void CreateMyForm()
{
    // Create a new instance of the form.
    Form form1 = new Form();

    // Create two buttons to use as the accept and cancel buttons.
    Button button1 = new Button();
    Button button2 = new Button();

    // Set the text of button1 to "OK".
    button1.set_Text("OK");

    // Set the position of the button on the form.
    button1.set_Location(new Point(10, 10));

    // Set the text of button2 to "Cancel".
    button2.set_Text("Cancel");

    // Set the position of the button based on the location of button1.
    button2.set_Location(new Point(button1.get_Left(), 
        button1.get_Height() + button1.get_Top() + 10));

    // Set the caption bar text of the form.   
    form1.set_Text("My Dialog Box");

    // Display a help button on the form.
    form1.set_HelpButton(true);

    // Define the border style of the form to a dialog box.
    form1.set_FormBorderStyle(get_FormBorderStyle().FixedDialog);

    // Set the MaximizeBox to false to remove the maximize box.
    form1.set_MaximizeBox(false);

    // Set the MinimizeBox to false to remove the minimize box.
    form1.set_MinimizeBox(false);

    // Set the accept button of the form to button1.
    form1.set_AcceptButton(button1);

    // Set the cancel button of the form to button2.
    form1.set_CancelButton(button2);

    // Set the start position of the form to the center of the screen.
    form1.set_StartPosition(FormStartPosition.CenterScreen);

    // Add button1 to the form.
    form1.get_Controls().Add(button1);

    // Add button2 to the form.
    form1.get_Controls().Add(button2);

    // Display the form as a modal dialog box.
    form1.ShowDialog();
} //CreateMyForm
