c# - go to a page index corresponding to a specific record in a gridview -

hello working on web page written in asp , c#, can add, edit , delete records database. web page has grid view contains select, edit , delete links in each row, , rows ordered dates. question is: how can insert new record, , automatically go corresponding page? (taking example grid view page size 5)

this part of grid view

<asp:gridview id="grdschedulerapplications" runat="server" autogeneratecolumns="false"                             visible="false" showfooter="true" pagesize="5" datakeynames="sa_id, sa_applicationid"                             allowpaging="true" onrowcommand="grdschedulerapplications_rowcommand">                             <columns>                                 <asp:templatefield headertext="application" headerstyle-horizontalalign="left">                                     <edititemtemplate>                                         <asp:dropdownlist id="ddleditschedulerapplications" runat="server" autopostback="true"                                             datatextfield="app_name" datavaluefield="app_id">                                         </asp:dropdownlist>                                     </edititemtemplate>                                     <itemtemplate>                                         <%# eval("application")%>                                     </itemtemplate>                                     <footertemplate>                                         <asp:dropdownlist id="ddlschedulerapplications" runat="server" autopostback="true"                                             datatextfield="app_name" datavaluefield="app_id">                                         </asp:dropdownlist>                                     </footertemplate>                                 </asp:templatefield> 

and have c# code:

protected void grdschedulerapplications_rowcommand(object sender, gridviewcommandeventargs e)     {         if (e.commandname.equals("insert"))         {             try             {                 int saschdlrid;                 int.tryparse(grdbulkscheduler.selecteddatakey.values[0].tostring(), out saschdlrid);                 dropdownlist ddlschedulerapps = (dropdownlist)grdschedulerapplications.footerrow.findcontrol("ddlschedulerapplications");                  int appid;                 int.tryparse(ddlschedulerapps.selectedvalue.tostring(), out appid);                  //calling method class add/update records database                 object obj = cdata.addupdatebulkschedulerapplications(0, saschdlrid, appid);                  //query returns automatically incremented id of newly created record obj                 if (obj.tostring() != "0")                 {                     //do action                     //here need go corresponding page index                 }             }             catch (exception ex)             {                 //exception             }         } 

if data source returns rows ordered date , don't modify order, need set page index , rebind grid it's data source:

if (obj.tostring() != "0") {     grdschedulerapplications.pageindex = int32.parse(obj) / 5;     // todo: rebind grid (set data source , call databind()) }
