Why AllowPaging = true; isn't showing Page Numbering at all

Question

when I try,

GridView.PageSize = 5;
GridView.AllowPaging = true;
GridView.PageIndexChanging += new GridViewPageEventHandler(GridView_PageIndexChanging);

and I got this,

void GridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    if (GridView != null)
    {

        GridView.PageIndex = e.NewPageIndex;
        GridView.DataBind();
    }
}

Why I am not able to see page numbering at all, I am 100% sure there are more then 5 rows as when I increase pageSize property I can see them.

Answer 1

添加代码：

GridView.PagerSettings.Mode = PagerButtons.Numeric;

Answer 2

如果要动态添加控件，则必须在调用DataBind（）方法之前将控件添加到页面中，否则它不会显示页面数。
