Answer 2

to 第一问：请教DataGridView代码实现数据导航功能！实现四个导航：First,Previous,Next,Last,通过绑定数据源来实现，例如：
BindingManagerBase bm = yourGridView.BindingContext[yourGridView.DataSource];
//To first
bm.Position = 0;//To previous
bm.Position -= 1;//To next
bm.Position += 1;//To last
bm.Position = bm.Count - 1;to 另一问：DataGridView在第一列，如果按回车，跳到下一列，如果到最后一列，转行！How can I make the Enter Key behave like the Tab Key and move to the next cell?

这个方法也适合datagridview。

      return true;
     }
     return base.ProcessCmdKey(ref msg,keyData);}

public frmAUT101()
        {
            InitializeComponent();
            this.dGVUsers.AutoGenerateColumns = false;
            BindFieldsName();
            txtIDEnabled(false);

            DataRows = dGVUsers.Rows.Count - 1;
            //DataCurrentRow = 0;
            bmb = this.dGVUsers.BindingContext[dGVUsers.DataSource];
            bmb.CurrentChanged +=
   new EventHandler(BindingManagerBase_CurrentChanged);            
        }
