In this paper, an example is given to describe the general paging function implemented by Asp. Net. Share it for your reference, as follows:
Functions:
1. Each page is set to display 9 pages. If it exceeds 9 pages, click +1 page after 5 pages (you can modify it at will)
2. CSS style can be set by itself
3. No code is generated, which is beneficial to search engine optimization
Paging program
objPDS = new PagedDataSource();
objPDS.DataSource = dtTable.DefaultView;// Bind data source
objPDS.AllowPaging = true;
objPDS.PageSize =10;// Number of pages
int curPage;
int cshi;
int jshi;
int zyes = Int32.Parse( objPDS.PageCount.ToString());
this.tjixx.Text = " Total <font color=red>" + dtTable.Rows.Count + " </font> Items of information ";
this.tjixx.Text += "| Altogether <font color=red>" + zyes + " </font> Page ";
if (Request.QueryString["Page"] != null)
{
if (Int32.Parse(Request.QueryString["Page"]) > zyes)
curPage = zyes;
else
curPage = Int32.Parse(Request.QueryString["Page"]);
}
else
{
curPage = 1;
}
if (zyes <= 9)
{

}

}
else

}
}
objPDS.CurrentPageIndex = curPage - 1;

this.DataList4.DataBind();
Aspx file:
Paging section:
<div align="center"> <asp:HyperLink ID="linkFirstPage" runat="server" Font-Underline="False"> Home page </asp:HyperLink><<
<asp:HyperLink ID="linkPre" runat="server" Font-Underline="False"> Upper 1 Page </asp:HyperLink>
<asp:Literal ID="yemsl" runat="server"> </asp:Literal>
<asp:HyperLink ID="linkNext" runat="server" Font-Underline="False"> Under 1 Page </asp:HyperLink>
>> <asp:HyperLink
ID="linkEndPage" runat="server" Font-Underline="False"> End page </asp:HyperLink>| <asp:Literal
ID="tjixx" runat="server"> </asp:Literal> </div>
