you may try the Edit1KeyDown as the WM_CHAR is not issued at all for VK_RETURN and the WM_KEYUP might not be handled if there was already a handler before.<br />
<br />
VK_RETURN ('\r' or 0x0D) often was handled by accelerators. in a form enter key would be redirected to a button-click of the default pushbutton (normally the ok button). in the OnOk you could find out if the return key was pressed by checking whether the ok button has not the focus.<br />

Thanks for your comment, I get the same for Edit1KeyDown. I have solved the problem initially by using the event handler's Key parameter as follows but this does not agree with the &nbsp;documentation which suggests that the Key parameter is the specific code at the keyboard hardware level. In both KeyDown and KeyUp, the value of the KeyChar character is L&quot;&quot; when the return or Enter key is entered.<br />
So I have changed the code as follows:<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42047597-1"><span>void __fastcall TForm1::Edit1KeyUp(TObject *Sender, WORD &amp;Key, System::WideChar &amp;KeyChar,</span>
<span>		  TShiftState Shift)</span>
<span>{</span>
<span>	if(KeyChar=='\0')</span>
<span>		Button1Click(NULL);</span>
<span>}</span>
</code></pre>
</div>


<div>
Thanks for your comments. I will investigate further to determine how to implement the code that you suggest.<br />

FMX TEdit KeyUp handler detecting  &quot;enter&quot; key

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

Delphi is the most powerful Object Pascal IDE and component library for cross-platform Native App Development with flexible Cloud services and broad IoT connectivity. It provides powerful VCL controls for Windows 10 and enables FMX development for Windows, Mac and Mobile. Delphi is your choice for ultrafast Enterprise Strong Development™. Look for increased memory for large projects, extended multi-monitor support, improved Object Inspector and much more. Delphi is 5x faster for development and deployment across multiple desktop, mobile, cloud and database platforms including 32-bit and 64-bit Windows 10.
