The invalid Focus solution is called inside Form_Load

Because I think SplitContainer's dashed line is ugly, I want to move the focus to another control when the program starts.

Added in Form_Load

listview1.Focus();

It didn't work.

I looked it up and found the reason:

When Form_Load is called, Form is not yet in the presentation stage, so the Focus() call will not work.

Solutions:

Call this.Show () before Focus();

Or, more simply, move the Focus() function call to Form_Shown event handling.
