when i press enter key on no button of messagebox, mBtnSaveUnita_KeyUp is invoked (because save button is focused)<br />

</div>


<div>
I would recommend using KeyPressed event instead of KeyUp.<br />
KeyDown and KeyUp are very low level events which should only be used in some special cases.
</div>


<div>
I have no keypressed method but only keypress with a KeyPressEventArgs arguments, how can i check if user press enter key in this way?<br />

</div>


<div>
ok, in this way I solve my problem thanks

Enter Key and MessageBox Problem

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
