How to implicitly show IntelliSense without declaring "using"

Hello forum,

I am evaluating the SyntaxEditor for Windows Forms. It is an awesome IDE control really! But I don't know how to enable IntelliSense without declaring "using" in the code. For example the following code will show the IntelliPrompt MemberList of the class MessageBox when I hit period "." after MessageBox:

using System.Windows.Forms;
class Test
{
	void Main()
	{
		MessageBox.Show("Hello");		
	}
}

However, on the code editor, I just want to show only the simple code MessageBox.Show("Hello") and hide all using (System.Windows.Forms), class (Test) and method name (Main). It just likes Immediate Window or QuickWatch on Visual Studio, that we can show intellisense of a class or variable without full source code. How can I accomplish the same feature with SyntaxEditor.

Thank you,

Dylan
