still looking for removing row from datagridview in window application.

You have received help in your previous two threads with this question and in this thread. People are trying to help you.
 
Another possibility is my article Database Table Update in a DataGridView without Writing Code.

Assuming tableadapter is your typed TableAdapter and ds is the dataset name,

private void datagvw_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
{
 int i = e.Row.Index;
 tableadapter.Adapter.DeleteCommand = new SqlCommand("Delete from Products where ProductCode=" + ds.Books.Rows[i][0], tableadapter.Connection);
 tableadapter.Adapter.DeleteCommand.ExecuteNonQuery();
}

i dont even know the procedure.
please tell me the whole code.

Are you using a binding source or binding navigator with the datagridview?
