How to disable a form resize at design time?

Question

In my application I am deriving all my forms from a common BaseForm.

Now I need to disable the resizing in the BaseForm so that derived forms are not resizable at design-time.

How to achieve that?

I need it at design-time

Answer 1

Use the following:

this.FormBorderStyle = FormBorderStyle.FixedSingle;  

Answer 2

If you go into design view and look in the form's properties menu, there is a Locked property, which disables resizing of the form.

EDIT

Try setting the MaximumSize and MinimumSize properties to the same value.

Answer 3

This seems to work:

[BaseForm.cs]

namespace WindowsFormsApplication1
{
    using System.Windows.Forms;

    public partial class BaseForm : Form
    {
        public BaseForm()
        {
            InitializeComponent();

            this.MaximumSize = this.MinimumSize = this.Size;
        }
    }
}

[DerivedForm.cs]

namespace WindowsFormsApplication1
{
    public partial class DerivedForm : WindowsFormsApplication1.BaseForm
    {
        public DerivedForm()
        {
            InitializeComponent();
        }
    }
}
