<div class="markdown level1 remarks"><p>Call the <b>IsInputKey</b> method to determine whether the key specified by the keyData
parameter is an input key that the control requires. This method is called during window
message preprocessing to determine whether the specified input key should be
preprocessed or sent directly to the control. If <b>IsInputKey</b> returns <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">true</a>,
the specified key is sent directly to the control. If <b>IsInputKey</b> returns <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">false</a>,
the specified key is preprocessed and only sent to the control if it is not consumed
by the preprocessing phase. Keys that are preprocessed include the Tab, Return, Esc,
and the Up Arrow, Down Arrow, Left Arrow, and Right Arrow keys.</p>
