Question

有没有办法检测Grid Control垂直滚动条是可见还是隐藏。或者如果隐藏或可见，则返回值的属性？我目前正在使用开发快递网格控制任何人都可以提供答案吗？我一直在寻找几个小时，但我找不到答案。

Answer 1

这适用于旧版本的DevExpress网格视图。我也使用标准反射得到null。

private GridViewInfo GetViewInfo(GridView view)
    {
        FieldInfo fi;

        fi = typeof(GridView).GetField("fViewInfo", BindingFlags.NonPublic | BindingFlags.Instance);

        GridViewInfo griInfo = fi.GetValue(view) as GridViewInfo;
        if (griInfo != null)
         {
          // check if scrollbar
          if (griInfo.VScrollBarPresence == ScrollBarPresence.Visible)
          {
              Console.WriteLine("Scrollbar visible");
          }
          else
          {
              Console.WriteLine("Scrollbar not visible");
          }
        }
        return griInfo;
    }

Answer 2

网格控制不提供此类属性。你为什么不使用XtraScrollableControl？

Answer 3

    private void button1_Click(object sender, EventArgs e)
    {
        // create a long list to force scrollbar
        List<String> tempList = new List<string> { "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value", "1 value" };
        gridControl1.DataSource = tempList;

        // check if scrollbar is visible
        GridViewInfo viewInfo = gridView1.GetViewInfo() as GridViewInfo;
        if (viewInfo != null)
        {
            // check if scrollbar
            if (viewInfo.VScrollBarPresence == ScrollBarPresence.Visible)
            {
                Console.WriteLine("Scrollbar visible");
            }
            else
            {
                Console.WriteLine("Scrollbar not visible");
            }
        }
    }
