Property Value

Type: System.Windows.Input::KeyStates

The state of the key.

A key can be in both the up and toggled states or the down and toggled states. For this reason, determining whether a key is up or down is not as simple as checking the KeyStates value as a numeric value. Instead, you should check the value by treating it as a flag enumeration. Use an AND comparison of the first bit. Alternatively, use the helper properties IsUp, IsDown, and IsToggled to determine whether a given key is up, down, or toggled.

The following example checks whether a key associated with an instance of KeyEventArgs is down by performing a bitwise AND comparison on the KeyStates of the key and the Down enumeration value.
