MaximumSize Property

Form.MaximumSize Property


Gets the maximum size the form can be resized to.

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

public override Size MaximumSize { get; set; }

Property Value

Type: System.Drawing.Size

A Size that represents the maximum size for the form.

Exception Condition

The values of the height or width within the Size object are less than zero.

This property enables you to limit the size of a form to a specified maximum size. You can use this feature when displaying multiple windows at the same time, to ensure that a single window does not cause other windows to be hidden. If this property is set to a Size object that is 0 in height and 0 in width, the form will have no maximum size beyond the limits set by Windows.

The following code example demonstrates setting the MaximumSize property.

public Form1() : base()

	//This call is required by the Windows Form Designer.

	//Set the maximum size, so if user maximizes form, it 
	//will not cover entire desktop.  
	this.MaximumSize = new System.Drawing.Size(500, 500);
