public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();            DisplayHScroll();        }        /// 
        /// 获取或设置一个值，该值指示是否在控件中显示水平滚动条        /// 
        private void DisplayHScroll()        {            checkedListBox1.IntegralHeight = true;            for (int x = 0; x < 10; x++)            {                checkedListBox1.Items.Add("Item  " + x.ToString() + " is a very large value that requires scroll bars");            }            checkedListBox1.HorizontalScrollbar=true;        }    }
