set focus from class library
<p>In my C# (3.5) solution, i have 2 projects- a Class Library and WinForm project.</p>

<p>All business logic are in class library. while adding/updating data from WinForm, if Class Library finds any error, it will raise error and set focus to associate control in WinForm.</p>

<p>Is it possible?</p>

<p>Thanks,
SKPaul.</p>
