Description

When using the RadCalculatorPicker on a device without a numeric keypad, the decimal key does not work as expected. This article demonstrates how to make RadCalculatorPicker recognize the period or comma key as a decimal separator.

Solution

To make RadCalculatorPicker recognize the period (.) or comma (,) key as the decimal separator, subscribe to the KeyDown event and execute the RadCalculatorCommands.UpdateInput command.

private void RadCalculatorPicker_KeyDown(object sender, System.Windows.Input.KeyEventArgs e) 
{ 
    if (e.Key == System.Windows.Input.Key.OemPeriod) 
    { 
        RadCalculatorCommands.UpdateInput.Execute(CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator); 
    } 
}
