i following tutorial how copy selected rows or records 1 gridview in asp.net using checkboxes http://www.aspsnippets.com/articles/transfer-selected-rows-from-one-gridview-to-another-in-asp.net.aspx first gridbox follows:

<div id="dialog">         <asp:gridview id="gvitems" runat="server" autogeneratecolumns="false"              datakeynames="sno" cellpadding="4" forecolor="#333333" gridlines="none" onpageindexchanging="onpageindexchanging"         pagesize="5" allowpaging="true"              onselectedindexchanged = "onselectedindexchanged">             <alternatingrowstyle backcolor="white" />             <columns>                <asp:templatefield>         <headertemplate>             <asp:checkbox id="chkall" runat="server"             autopostback = "true"  oncheckedchanged = "checkbox_checkchanged"/>         </headertemplate>          <itemtemplate>             <asp:checkbox id="chk" runat="server"             autopostback = "true"  oncheckedchanged = "checkbox_checkchanged" />         </itemtemplate>     </asp:templatefield>        <asp:buttonfield text="select" commandname="select" itemstyle-width="50">  <itemstyle width="50px"></itemstyle>                 </asp:buttonfield>               <asp:boundfield datafield="sno" headertext="sno" />                 <asp:boundfield datafield="itemcode" headertext="item code"                      itemstyle-width="50" > <itemstyle width="50px"></itemstyle>                 </asp:boundfield> </columns>

and have used 2 javascript functions check , check all follows:

function check_click(objref) {     //get row based on checkbox     var row = objref.parentnode.parentnode;      //get reference of gridview     var gridview = row.parentnode;      //get input elements in gridview     var inputlist = gridview.getelementsbytagname("input");      (var i=0;i<inputlist.length;i++)     {         //the first element header checkbox         var headercheckbox = inputlist[0];          //based on or none checkboxes         //are checked check/uncheck header checkbox         var checked = true;         if(inputlist[i].type == "checkbox" && inputlist[i] != headercheckbox)         {             if(!inputlist[i].checked)             {                 checked = false;                 break;             }         }     }     headercheckbox.checked = checked;  } function checkall(objref) {     var gridview = objref.parentnode.parentnode.parentnode;     var inputlist = gridview.getelementsbytagname("input");     (var i=0;i<inputlist.length;i++)     {         var row = inputlist[i].parentnode.parentnode;         if(inputlist[i].type == "checkbox"  && objref != inputlist[i])         {             if (objref.checked)             {                 inputlist[i].checked=true;             }             else             {                 if(row.rowindex % 2 == 0)                 {                    row.style.backgroundcolor = "#c2d69b";                 }                 else                 {                    row.style.backgroundcolor = "white";                 }                 inputlist[i].checked=false;             }         }     } } //--> </script>

it working fine. need change first gridview popup gridview .so, have used javascript functions show popup folllows: 

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/jquery-ui.js" type="text/javascript"></script> <link href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/themes/start/jquery-ui.css"     rel="stylesheet" type="text/css" /> <script type="text/javascript">     $(function () {         $("[id*=btnshowpopup]").click(function () {             showpopup();             return false;         });     });     function showpopup() {         $("#dialog").dialog({             title: "gridview",             width: 550,             buttons: {                 ok: function () {                     $(this).dialog('close');                 }             },             modal: true         });         } </script>
