A long-standing question about usercontrol

Create a custom control

Namespace testcontrolnull
{
Public partial class UserControl1: UserControl
{
Public UserControl1 ()
{
InitializeComponent ();
}

Private entity e;

Public entity E
{
Get {return e ;}
Set {e = value ;}
}
}

Public class entity
{
Private decimal myVar;

Public decimal MyProperty
{
Get {return myVar ;}
Set {myVar = value ;}
}
}
}

When you drag a widget to a form, the following code is automatically generated:
This. userControl11.E = null;
This. userControl11.Location = new System. Drawing. Point (182,146 );
This. userControl11.Name = "userControl11 ";
This. userControl11.Size = new System. Drawing. Size (57, 77 );
This. userControl11.TabIndex = 0;

How to avoid this. userControl11.E = null;
