Repeater控件与PagedDataSource结合实现分页功能

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
int pageIndex = 1;
try
{
pageIndex = Convert.ToInt32(Request.QueryString["Page"]);
if (pageIndex <= 0) pageIndex = 1;
}
catch
{
pageIndex = 1;
}
DataTable dt = GetDocumentTable();
PagedDataSource pds = new PagedDataSource();
pds.DataSource = dt.DefaultView; // 设置数据源
pds.AllowPaging = true; // 设置指示是否启用分页的值
pds.PageSize = 5; // 设置要在每页显示的数量
pds.CurrentPageIndex = pageIndex - 1; // 设置当前页的索引。
rptDocumentList.DataSource = pds;
rptDocumentList.DataBind();
ltlPageBar.Text = GetPageBar(pds);
}
}
// 分页条
private string GetPageBar(PagedDataSource pds)
{
string pageBar = string.Empty;
int currentPageIndex = pds.CurrentPageIndex + 1;
if (currentPageIndex == 1)
{
pageBar += "首页";
}
else
{
pageBar += " + Request.CurrentExecutionFilePath + "?Page=1">首页";
}
if ((currentPageIndex - 1) < 1)
{
pageBar += "上一页";
}
else
{
pageBar += " + Request.CurrentExecutionFilePath + "?Page=" + (currentPageIndex - 1) + "">上一页";
}
if ((currentPageIndex + 1) > pds.PageCount)
{
pageBar += "下一页";
}
else
{
pageBar += " + Request.CurrentExecutionFilePath + "?Page=" + (currentPageIndex + 1) + "">下一页";
}
if (currentPageIndex == pds.PageCount)
{
pageBar += "末页";
}
else
{
pageBar += " + Request.CurrentExecutionFilePath + "?Page=" + pds.PageCount + "">末页";
}
return pageBar;
}
// 创建测试表
DataTable GetDocumentTable()
{
DataTable dt = new DataTable();
dt.Columns.Add("DocumentId", typeof(int));
dt.Columns.Add("Title", typeof(string));
for (int i = 1; i <= 30; i++)
{
DataRow row = dt.NewRow();
row["DocumentId"] = i;
row["Title"] = "文档标题 " + i + "";
dt.Rows.Add(row);
}
return dt;
}
