//调用完上述函数后，要手动重绘，Gird.Invalidate()。
//利用反射你可以充分的自定义DataGrid的一些隐藏属性，并使用它的一些非公开的方法, 比如以下代码打印了所有DataGrid的隐藏属性:
public void PrintField()
{
    System.Reflection.FieldInfo[] fis = typeof(DataGrid).GetFields(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static);
    string str = "";
    foreach (var fi in fis)
    {
        str+=fi.Name + ":" + fi.FieldType.ToString()+"\r\n";
    }
    MessageBox.Show(str);
