c# - Having text inside NumericUpDown control, after the number

Question

Is it possible in WinForms to show a text inside a NumericUpDown control? For example I want to show the value in my numericupdown control is micro ampers so it should be like "1 uA".

Thanks.

There's no such functionality built into the standard control. However, it's fairly easy added by creating a custom control that inherits from the NumericUpDown class and overrides the UpdateEditText method to format the number accordingly.

For example, you might have the following class definition:

public class NumericUpDownEx : NumericUpDown
{
    public NumericUpDownEx()
    {
    }

    protected override void UpdateEditText()
    {
        // Append the units to the end of the numeric value
        this.Text = this.Value + " uA";
    }
}

Or, for a more complete implementation, see this sample project: NumericUpDown with unit measure
