I am getting  'Error in Loading Data'  while using highcharts. I am testing this in firefox with flashplayer disabled. ( I works fine with flash player) 
  
I am setting the 'DataUrl' to an aspx page(GetFusionChartData.aspx). Below is the code snippet. 
  
Display.aspx ( In this page we are capturing the parameters and pass it as query string to 'GetFusionChartData.aspx 
StringBuilder script = new StringBuilder(); 
  
script.AppendFormat("\r\n\r\nvar chartctrl{0} = new FusionCharts('../../SWF/FusionCharts/{1}?ChartNoDataText=No data found&LoadDataErrorText=No data found&InvalidXMLText=No data found', 'chart{0}', '{2}', '{3}', '0', '1');", ReportItem.ID, GetChartSWF(), flashWidth,flashHeight); 
  
script.AppendFormat("\r\nchartctrl{1}.setDataURL(escape('GetFusionChartData.aspx?RequireInitial={2}&ReportID={0}&ItemID={1}&' + escape(BuildFilterQueryString({1})) +'&ItemTitle='+ escape(GetReportItemTitle({1}))));", Report.ID, ReportItem.ID, this.RequiresInitialSelection); 
  
script.AppendFormat("\r\nchartctrl{0}.render('chart{0}div');\r\n", ReportItem.ID); 
  
writer.Write(script);      //write it to be renderred in the client. 
  
  
Below is GetFusionChartData.aspx 
<%@ Page Language="C#" AutoEventWireup="true"  Inherits="Reports.RenderingControl.FusionCharts.FusionChartRenderingPage" %> 
<head runat="server"></head> 
  
GetFusionChartData.aspx.cs 
 protected void Page_Load(object sender, EventArgs e) 
 { 
     //Get the parameters from the query string and connect to the database and get the data and generate the xml data and add it as inline chart xml 
 } 
  
  
  
  
Thanks.
