c# - How to make each button respond to that row only -

-

i have repeater creates table multiple row same field name:

<asp:repeater runat="server" id="rptcontent">             <headertemplate>                 <table border="0" style="width: 95%;">                     <tr>                         <td style="width: 25%;">name</td>                         <td style="width: 25%;">last 4 ssn #</td>                         <td style="width: 25%;">pdf generator</td>                     </tr>             </headertemplate>             <itemtemplate>                     <tr>                         <td><%# eval("name").tostring() %></td>                         <td><%# eval("ssn3").tostring() %></td>                         <td><asp:button id="btngeneratepdf" runat="server" text="generate pdf for" onclick="btngeneratepdf_click" /></td>                     </tr>             </itemtemplate>             <footertemplate>                 </table>             </footertemplate>         </asp:repeater>

my code behind looks this:

public void writedata()     {         conn = new sqlconnection(cstring);         conn.open();          namee = txtname.text;          var pdfpath = path.combine(server.mappath("~/pdftemplates/9.pdf"));          // form fields pdf , fill them in!         var formfieldmap = pdfhelper.getformfieldnames(pdfpath);         formfieldmap["topmostsubform[0].page1[0].f1_01_0_[0]"] = txtname.text;          sqlcode = "select * [db].[dbo].[tablepdftest] [name] = '" + namee + "'";          using (sqlcommand command = new sqlcommand(sqlcode, conn))         {             command.commandtype = commandtype.text;              using (reader = command.executereader())             {                 if (reader.hasrows)                 {                     if (reader.read())                     {                         formfieldmap["topmostsubform[0].page1[0].f1_02_0_[0]"] = reader.getvalue(1).tostring();                         formfieldmap["topmostsubform[0].page1[0].f1_04_0_[0]"] = reader.getvalue(2).tostring();                         formfieldmap["topmostsubform[0].page1[0].f1_05_0_[0]"] = reader.getvalue(3).tostring();                         formfieldmap["topmostsubform[0].page1[0].f1_07_0_[0]"] = reader.getvalue(4).tostring();                         formfieldmap["topmostsubform[0].page1[0].social[0].textfield1[0]"] = reader.getvalue(5).tostring();                         formfieldmap["topmostsubform[0].page1[0].social[0].textfield2[0]"] = reader.getvalue(6).tostring();                         formfieldmap["topmostsubform[0].page1[0].social[0].textfield2[1]"] = reader.getvalue(7).tostring();                         formfieldmap["topmostsubform[0].page1[0].social[0].textfield2[2]"] = reader.getvalue(8).tostring();                         formfieldmap["topmostsubform[0].page1[0].social[0].textfield2[3]"] = reader.getvalue(9).tostring();                     }                 }             }         }          // requester's name , address (hard-coded)         formfieldmap["topmostsubform[0].page1[0].f1_06_0_[0]"] = "medical group\n2700 wr ave\npurchase, ny 10232";          var pdfcontents = pdfhelper.generatepdf(pdfpath, formfieldmap);          pdfhelper.returnpdf(pdfcontents, "compl.pdf");     }

how can make if there more 1 entries each button query [name] last 4 ssn different?

first, nod using parameters...

anyway, lot of ways this, 1 add commandargument value button (and evaluate in code behind).

<asp:button     id="btngeneratepdf"     runat="server"     text="generate pdf for"     commandargument = '<%# eval("l4_ssn") %>'     onclick="btngeneratepdf_click" />

then you'd need make sure had field in select statement such right(ssn,4) l4_ssn

and finally, you'd modify btngeneratepdf_click sub evaluate e.commandargument...

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
