<h5 id="GrapeCity_Win_Spread_InputMan_CellType_EditBase_IsInputChar_System_Char__remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>Call the <b>IsInputChar</b> method to determine whether the character specified by
the charCode parameter is an input character that the control requires.
This method is called during window message preprocessing to determine
whether the specified input character should be preprocessed or sent directly to the control.
If <b>IsInputChar</b> returns <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">true</a>, the specified character is sent directly to the control.
If <b>IsInputChar</b> returns <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">false</a>, the specified character is preprocessed and
only sent to the control if it is not consumed by the preprocessing phase.
The preprocessing of a character includes checking whether the character is a mnemonic of
another control.</p>
