You should use the SpinEdit control and set the max and min properties.


You could set the regexp mask to \d|[0-2]\d|30.


Handle the EditValueChanging event,

private void txtQuantity_EditValueChanging(object sender, ChangingEventArgs e)
{
    var value = Convert.ToDouble(e.NewValue);
    if (value < MIN || value > MAX) e.Cancel = true;
}


In winforms you should use System.Windows.Forms.NumericUpDown and set the Maximum and Minimum properties.
