How to create 'KeyDown' event programmatically for gridview?

Question

I have two DataGridViews (DataGridView1 and DataGridView2 ).

I have created KeyDown event for DataGridview1 in

DataGridview1_EditingControlShowing event(object sender, DataGridViewEditingControlShowingEventArgs e)

{ 

e.Control.KeyDown +=new KeyEventHandler(Control_KeyDown);

} 

but, when i tried to create same event for DataGridView2 

DataGridview2_EditingControlShowing event(object sender, DataGridViewEditingControlShowingEventArgs e)

{

e.Control.KeyDown +=new KeyEventHandler(Control_KeyDown); //   error:  " handler Control_KeyDown already exists in this class "

}

How to crate KeyDown event Programmatically for DataGridView2 in same windows form?
