how do i restrict numericupdown control to accept only integers

Question

I have a windows numericupdown control. I want to restrict it so that user can only enter integers in it. How do I do that? At present a user can enter a decimal number as well. Thanks PS I am using .net

Answer 1

I did a little experimenting and found this workaround:

    private void numericUpDown1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar < 48 || e.KeyChar > 57)
        {
            e.Handled = true;
        }
    }

This way you will not be able to type thousand separators either but you could add that by first finding out what the thousand separator is and allowing that too.

Answer 2

Set the DecimalPlaces property to zero.
