    //When no Records Are Being Displayed
    private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)
    {
    //方法一(此方法为GridView设置了数据源绑定时,可用) 
    ColumnView columnView = sender as ColumnView;
    BindingSource bindingSource = this.gridView1.DataSource as BindingSource;
    if(bindingSource.Count == 0)
    {
    string str = "没有查询到你所想要的数据!";
    Font f = new Font("宋体", 10, FontStyle.Bold);
    Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);
    e.Graphics.DrawString(str, f, Brushes.Black, r);
    }
    //方法二(此方法为GridView没有设置数据源绑定时,使用,一般使用此种方法) 
    if (this._flag)
    {
    if (this.gridView1.RowCount == 0)
    {
    string str = "没有查询到你所想要的数据!";
    Font f = new Font("宋体", 10, FontStyle.Bold);
    Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);
    e.Graphics.DrawString(str, f, Brushes.Black, r);
    }
    }
    }

    九、如何显示水平滚动条?

    设置this.gridView.OptionsView.ColumnAutoWidth = false;

    十、如何定位到第一条数据/记录?

    设置 this.gridView.MoveFirst()

    十一、如何定位到下一条数据/记录?

    设置 this.gridView.MoveNext()

    十二、如何定位到最后一条数据/记录?

    设置 this.gridView.MoveLast()

    十三、设置成一次选择一行,并且不能被编辑

    this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

    十四、如何显示行号?

    this.gridView1.IndicatorWidth = 40; 
    //显示行的序号 
    private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
    {
    if (e.Info.IsRowIndicator && e.RowHandle>=0)
    {
    e.Info.DisplayText = (e.RowHandle + 1).ToString();
    }
    }

    十五、如何让各列头禁止移动?

    设置gridView1.OptionsCustomization.AllowColumnMoving = false;

    十六、如何让各列头禁止排序?
