WPF - Checking Cap Lock Status in WPF

Checking Cap Lock status will be useful in Logon page where we can provide warning to user <Caps Lock is on. Having Caps Lock on may cause you to enter password incorrectly.>

Following sample uses the Control class that is a standard class within the System.Windows.Forms namespace. The DLL containing this namespace is automatically included in Windows Forms applications. The class includes a method named IsKeyLocked, which allows you to determine whether keys such as Caps Lock are switched on or off. To check the status of the Caps Lock key, you can use the method in the following manner:

Example:
privatevoid KeyDownEventHanlder(object sender, KeyEventArgs e)
{
if (Console.CapsLock == true)
{
lblError.Foreground = Brushes.Red;
lblError.Content = "Caps Lock is on.";// Having Caps Lock on may cause you to enter password incorrectly.";

}

else

{
if (lblError.Foreground == Brushes.Red)lblError.Foreground = Brushes.Transparent;
}

}
