限制要在自定义分页上显示的页码

Question

http://www.aspsnippets.com/Articles/Custom-Paging-in-ASPNet-GridView-using-SQL-Server-Stored-Procedure.aspx

基于上面的教程,我能够在gridview上创建自定义分页,但是,我想限制页面上显示的页码.示例当我有10,000个记录以每页10行显示时,页面链接将加载1到1000个页面链接,这是不理想的.

如何使输出像这样:

先1 2 3 4 5 6 7 8 9 10最后

并自动调整

最后2 3 4 5 6 7 8 9 10 11

等等.

这是创建显示设置的所有页面的代码

private void PopulatePager(int recordCount, int currentPage)
{
    double dblPageCount = (double)((decimal)recordCount / decimal.Parse(ddlPageSize.SelectedValue));
    int pageCount = (int)Math.Ceiling(dblPageCount);
    List<ListItem> pages = new List<ListItem>();
    if (pageCount > 0)
    {
        pages.Add(new ListItem("First", "1", currentPage > 1));
        for (int i = 1; i <= pageCount; i++)
        {
            pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPage));
        }
        pages.Add(new ListItem("Last", pageCount.ToString(), currentPage < pageCount));
    }
    rptPager.DataSource = pages;
    rptPager.DataBind();
}

如果阻止此更改您

if (pageCount > 0)
{
    int showMax = 10;
    int startPage;
    int endPage;
    if (pageCount <= showMax) 
    {
        startPage = 1;
        endPage = pageCount;
    }
    else
    {
        startPage = currentPage;
        endPage = currentPage + showMax - 1;
    }

    pages.Add(new ListItem("First", "1", currentPage > 1));

    for (int i = startPage; i <= endPage; i++)
    {
        pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPage));
    }

    pages.Add(new ListItem("Last", pageCount.ToString(), currentPage < pageCount));
}

根据需要更改showMax.
