<---- below code used piechart.aspx.cs ---->

  protected void page_load(object sender, eventargs e)     {     }     public chart chartuser(string userid)     {         chart c = new chart();         sqlconnection con = new sqlconnection("data source=.;initial catalog=emp;integrated security=true");         // sqldataadapter da = new sqldataadapter("select * chartpie id= userid + "'", con);         con.open();         sqlcommand cmd = new sqlcommand("select * chartpie id='" + userid + "'", con);         sqldatareader dr = cmd.executereader();         while (dr.read())         {             c.userid = dr["userid"].tostring();             c.language = dr["language"].tostring();             c.percentage = dr["percentage"].tostring();         }          return c;     }     public class chart     {         public string userid { get; set; }         public string language { get; set; }         public string percentage { get; set; }      } }

<---- give below code used script file ----->

var chart = amcharts.makechart("chartdiv", {             "type": "pie",             "theme": "none",             "legend": {                 "markertype": "circle",                 "position": "right",                 "marginright": 80,                 "automargins": false             },             "dataprovider": [{                 "language": "tamil",                 "percentage": 50             }, {                 "language": "english",                 "percentage": 40             }, {                 "language": "hindi",                 "percentage": 30             }],             "valuefield": "percentage",             "titlefield": "language",             colorfield: "color",             "balloontext": "[[title]]<br><span style='font-size:14px'><b>[[value]]</b> ([[percents]]%)</span>",             "exportconfig": {                 "menutop": "0px",                 "menuitems": [{                     "icon": '/lib/3/images/export.png',                     "format": 'png'                 }]             }         });

kindly tell me how can value database?

modify script this. send ajax request asp.net page , assign result amchars dataprovider.

<script type="text/javascript">     $(document).ready(function () {          $.ajax({              type: "post",             contenttype: "application/json; charset=utf-8",             url: "piechart.aspx/chartuser",             data: "{userid : '123'}",             datatype: "json",             success: function (data) {              amcharts.makechart("chartdiv", {             "type": "pie",             "theme": "none",             "legend": {                 "markertype": "circle",                 "position": "right",                 "marginright": 80,                 "automargins": false             },             "dataprovider": [data.chart],             "valuefield": "percentage",             "titlefield": "language",             colorfield: "color",             "balloontext": "[[title]]<br><span style='font-size:14px'><b>[[value]]</b> ([[percents]]%)</span>",             "exportconfig": {                 "menutop": "0px",                 "menuitems": [{                     "icon": '/lib/3/images/export.png',                     "format": 'png'                 }]             }            });              },             error: function (result) {                 alert("error");             }         });     }); </script>
