全编辑WebGrid控件LrcGrid(5)―― 构造函数、变量和属性
LrcGrid从System.Web.UI.WebControls.Table继承，实现INamingContainer接口
元数据属性和构造函数：元数据声明了控件的标签和默认属性，构造函数为控件一些属性指定了默认值．
[
ToolboxData("<{0}:LrcGrid runat=server>"),
DefaultProperty("SelSql")
]
public class LrcGrid : System.Web.UI.WebControls.Table,INamingContainer
{

public LrcGrid() : base()
{
Font.Name = "verdana";
Font.Size = FontUnit.Point(8);
BackColor = Color.White;
ForeColor = Color.Black;
BorderStyle = BorderStyle.Outset;
Border1px");
PagerStyle = PagerStyle.NextPrev;
CurrentPageIndex = 0;
ItemsPerPage = 15;
TotalPages = -1;
IsPager = true;
}
