page spanning

bono20 · #1 Aug 25th, 2004, 10:44

I wonder if anyone could help me on this one. At the moment when data is displayed from the database it is listed all on one page, extending down as far as its needs to. What I would like to do is limit it to a set number of records and span it over a number of pages which can be selected.

Does anyone know how to do this easily?

Cheers

John

sure thing dude, its called "paging", there are millions of examples out there, heres an easy one:

Code: Select all

<%
set conn = Server.CreateObject("ADODB.Connection")
conn.Open "DSN=AdvWorks"

set rs = Server.CreateObject("ADODB.Recordset")
rs.CursorLocation = 3  ' adUseClient
rs.Open "Select * from Employees", conn
rs.PageSize = 2
intPageCount = rs.PageCount

Select Case Request("Action")
	case "<<"
		intpage = 1
	case "<"
		intpage = Request("intpage")-1
		if intpage < 1 then intpage = 1
	case ">"
		intpage = Request("intpage")+1
		if intpage > intPageCount then intpage = IntPageCount
	Case ">>"
		intpage = intPageCount
	case else
		intpage = 1
end select
%>
<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE>ASP & ADO Paging</TITLE>
</HEAD>
<BODY bgColor=White text=Black>

<%
rs.AbsolutePage = intPage 
For intRecord = 1 To rs.PageSize 
	Response.Write "Record	number: " & intRecord & " " 
	Response.Write rs.Fields("FirstName") & " " 
	Response.Write rs.Fields("LastName") & "
" 
	rs.MoveNext
If rs.EOF Then Exit For 

Next

rs.Close
set rs = Nothing
conn.Close
set conn = nothing
%>
<form name="MovePage" action="default.asp" method="post">
<input type="hidden" name="intpage" value="<%=intpage%>">
<input type="submit" name="action" value="<<">
<input type="submit" name="action" value="<">
<input type="submit" name="action" value=">">
<input type="submit" name="action" value=">>">
Page: <%=Intpage & " of " & intpagecount%>
</form>
</BODY>
</HTML>

or use Recordset.getRows to pull all the records into an array and Loop thru only the ones you want to display.

oh and don't use Request("intpage") - use Request.Querystring("intpage"). Otherwise expect random errors!!111!
