show error in this line
dgv_product.CellDoubleClick -= new DataGridViewCellEventHandler(dgv_product.CellDoubleClick);

error is,
The event 'System.Windows.Forms.DataGridView.CellDoubleClick' can only appear on the left hand side of += or -=

When form_2 is activate by clicking the button. then I want to disable the event..

Thank you sir. But these all about how can make a auto complete text box. My first cell is already an auto complete cell. My requirement is, the auto complete text box contains number of data. when cursor move upward or downward in the auto complete text box(here register.no) the next cell automatically shown student name. For this which event is used?
