Call C# Method using Javascript from ASP.Net with Parameters -

can help me phone call c# method in code behind using javascript in aspx page parameters?

here javascript have calls sample() method:

<script type="text/javascript"> function showmodal(arr, hey) { '<%=sample(arr,hey)%>'; } </script>

i have c# code called has 2 parameters:

protected string sample(int i, string a) { lblsample.text =i + "," + a; homecoming lblsample.text; }

this gave me error on javascript code:

arr not exist in current context

by way, javascript executed when particular bar in chart clicked. utilize fusioncharts.

here's code on how phone call , pass parameters showmodal javascript function:

xmlstring.appendformat("<set label='{3}' value='{1}' tooltext='employee: {0}{2}hours:{1}' link='j-showmodal-{1}, {1}'/>", dt.rows[i][1].tostring(), dt.rows[i][2].tostring(), "{br}", dt.rows[i]["empnamedot"].tostring());

expanding on david's answer: there many ways access server-side client-side after page rendered. partial list , in no particular order:

webmethod updatepanel asmx web service wcf web service web api signalr

the 1 take depends on trying achieve. in case, need create ajax request (this can done using jquery) , handle returned value in javascript code. seems using webforms. updatepanel webforms-ish way of doing this. updatepanel takes care of ajax calls you, need set correctly.

edit: if edit question improve explanation of trying achieve, maybe can provide more operative answer.
