    I am having difficulty exporting a pure JavaScript chart from the basic examples provided in the C# solution (demo package from fusion charts). My sample is from the evaluation code provided on the FusionChart website.

    I have added

    exportenabled='1' exportHandler='http://localhost:64162/CS/Export_Handler/FCExporter.aspx'

    to the existing Data.xml file in order to enable export using the local handler

    Chart definition for the chart BasicExample/MultiChartsJS.aspx:

     

    <chart caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0'
    formatNumberScale='0' showBorder='1' exportenabled='1' exportHandler='http://localhost:64162/CS/Export_Handler/FCExporter.aspx'>
    <set label='Jan' value='462' />
    <set label='Feb' value='857' />
    <set label='Mar' value='671' />
    <set label='Apr' value='494' />
    <set label='May' value='761' />
    <set label='Jun' value='960' />
    <set label='Jul' value='629' />
    <set label='Aug' value='622' />
    <set label='Sep' value='376' />
    <set label='Oct' value='494' />
    <set label='Nov' value='761' />
    <set label='Dec' value='960' />
    </chart>

     

    I am pointing the exportHandler to the C# export handler (FCExporter) found in the same solution.

    When invoking the export, the handler fires, but I am encountering two different runtime errors in the handler:

    Failures inside FCExporter.cs

    1)Jpeg conversion:

    gr.Clear(ColorTranslator.FromHtml("#" + rawImageData["bgcolor"].ToString()));

    is failing because rawImageData["bgcolor"] already contains a #

    2)PDF conversion

    int fRepeat = int.Parse(split_data[1]);

    is failing with an out of range exception

    It almost seems like the handler is out of sync with the charts that are being exported. It works if I point to the external fusion site for the export. Is there a new version of the handler available? I am using FusionCharts XT Version: 3.3.1.

     

    Thanks,

    Hi Shashibhushan,

     

    I tried using javascript variant  but result is same.

     

    Please find below steps i followed to export the charts in Asp.Net platform:

     

    1) Loading minimum 12 charts in aspx page in Page_Load() event

    2) after loading charts i need to export the same to ppt, so while populating chart i have added exportAction='save'   attribute to <chart> tag.

     

    Code : 

     

    xmlData.Append("<chart caption='" + ChartTitle + "' exportFileName='" + SaveFileName + "'  chartRightMargin='50' chartTopMargin='50'  xAxisName='' showLabels='1'  yAxisName='' canvasBorderThickness='1' divLineColor='FFFFFF' divLineThickness='0' divLineAlpha='0' decimalPrecision='2'  useRoundEdges='1' legendBorderAlpha='0' ");

    xmlData.Append(" rotateValues='1' showLegend='1'  rotateNames ='0' ");
     
    xmlData.Append(" exportEnabled='1' exportAction='save' exportAtClient='0' exportHandler='../Export_Handler/FCExporter.aspx' ");
     
    After all charts get downloaded i fetching that image file to export in ppt.
     
     
    I am fetching this issue in IE8,IE9 but same code working fine in Firefox.
     
     
    Our organisation is supposed to purchase a licence version but due to this issue we kept our decision on hold.
     
    Please look in to it.
     
    Thanks
