Manipulating Forms with the Windows Forms Library - 4.13 Limiting the Sizing of a Form
(Page 4 of 4 )

Problem

You want the user to be able to resize a form, but within limits.

Solution

Use the MinimumSize and MaximumSizeproperties of the form to limit the user’s adjustments of the form’s size. As with the standardSize property, these two properties encapsulate separate width and height values. Figure 4-16 shows these settings in use in the Properties panel.

Discussion

These properties do limit the size of the form, whether the user is resizing the form directly or your code sets the Size property. You will usually want to set the form’s FormBorderStyleproperty toSizable, and you must set theMaximizeBox property toFalse(or in some other way hide the maximize box, such as by setting theControlBox property toFalse).
