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)

member MinimizeBox : bool with get, set

Property Value

Type: System.Boolean
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.
