my code behind 

 public property pgnum() integer             if viewstate("pgnum") isnot nothing             return convert.toint32(viewstate("pgnum"))         else             return 0         end if     end     set(value integer)         viewstate("pgnum") = value      end set end property   protected sub page_load(sender object, e eventargs)     if not page.ispostback         bindrepeater()     end if end sub

i add bindrepeater sub bind datato repeater

 protected sub bindrepeater()          dim strsql string = "select  * news order news.item_id desc"         dim sqlconn new sqlconnection          sqlconn.connectionstring = configurationmanager.connectionstrings("mycon").tostring          sqlconn.open()         dim cmd new sqlcommand(strsql, sqlconn)        dim da new sqldataadapter(cmd)     dim ds new dataset     da.fill(ds)     cnt = ds.tables(0).rows.count     'dim table new datatable()     'da.fill(table)      dim pds new pageddatasource()     pds.datasource = ds.tables(0).defaultview     pds.allowpaging = true     pds.pagesize = 5     pds.currentpageindex = pgnum      txthidden.text = pgnum     dim vcnt integer = cnt / pds.pagesize     if pgnum < 1         btnprev.visible = false     elseif pgnum > 0         btnprev.visible = true     end if      if pgnum = vcnt         btnnext.visible = false     elseif pgnum < vcnt         btnnext.visible = true     end if      repeater1.datasource = pds     repeater1.databind()      sqlconn.close() end sub

'my paging buttons

protected sub btnnext_click(sender object, e system.eventargs) handles btnnext.click     pgnum += 1     bindrepeater() end sub   protected sub btnprev_click(sender object, e system.eventargs) handles btnprev.click     pgnum -= 1     bindrepeater() end sub   protected sub page_init(sender object, e system.eventargs) handles me.init     bindrepeater() end sub
