The NumericEdit control is a control derived from the TextBox control which accepts numeric type values only. It comes with spin up and spin down buttons to increment or decrement the numeric values. The control supports various numeric formats including Currency, DateTime, Scientific etc. using the FormatType property. You can set the Increment property to specify the interval by which spin buttons should increment or decrement the value. Moreover, NumericEdit lets you increase or decrease the values programmatically using SpinUp() or SpinDown() methods provided by the class.

numEdit = new C1NumericEdit();
Controls.Add(numEdit);
numEdit.Location = new Point(10, 170);
numEdit.Size = new Size(100, 30);
numEdit.Text = "12";
numEdit.NumericInputKeys = NumericInputKeys.All;
numEdit.Increment = "3";
