  1. Is it necessary to make head tag (<head> ) runat Server while rendering chart as an Image?

    in Web Forms

    Posted

    Hi

    i have drag and dropped chart control on an aspx page and rendered it as an image.

    when head tag is set to runat server, chart renders properly and every thing works fine, but i do not want to set head tad as runat server because from JavaScript i access server side variables using angular breakets(<% %>), if head tag is set to runat server i wont be able to access server side variable in javascript.

    when i do not set head tag as runat server the chart does not render properly, all the toolbar options are vertically visible above the chart and none of the option works.

    finally the question is:

    is it possible to render a chart properly as an image without setting head tag as runat server?

    i have attached the screen shot of the problem.

     Thanks,

    Divyesh.

  6. UserCommand event is not working

    in Web Forms

    Posted

    hi

    I have created custom command and added it to toolbar. Now on click of the custom command I want to perform some action for that I am using UserCommand event.

    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

     

    Problem is that UserCommand event is not occurring.

    code in default.aspx

    <

    chartfx7:Chart ID="departmentExpenceChart" runat="server" Height="250px" Width="375px" UseCallbacksForEvents="True" OnUserCallback="departmentExpenceChart_UserCallback" OnUserCommand="departmentExpenceChart_UserCommand" RenderFormat=".NET">

    <Series>

    <chartfx7:SeriesAttributes />

    <chartfx7:SeriesAttributes />

    <chartfx7:SeriesAttributes />

    </Series>

    <ToolBar Visible="True" />

    </chartfx7:Chart>

     

    the departmentExpenceChart_UserCommand method is in default.aspx.cs

    protected void departmentExpenceChart_UserCommand(object sender, CommandUIEventArgs e)

    {

    if (e.CommandId == 23)

    {

    if (departmentExpenceChart.Series[0].Visible == true)

    {

    departmentExpenceChart.Series[0].Visible = false;

    }

    else

    {

    departmentExpenceChart.Series[0].Visible = true;

    }

    }

     

    }

     

    on page load event i have written

    departmentExpenceChart.UserCommand +=

    new ChartFX.WebForms.CommandUIEventHandler(departmentExpenceChart_UserCommand);

    but still UserCommand event is not working...am i doing any thing wrong???

    pls reply as soon as possible..

  7. chart does not load if render format is .NET control

    in Web Forms

    Posted

    hi

    i am posting demo code. if u can suggest how this demo code will work fine then i will do the same changes in my original code.( i can not post original code due to company policies)

    default.aspx : this page contains code to generate chart. here  i creating just a default chart which comes by default when we drag and drop chart object on page

    code:

    <

    asp:Panel ID="ControlPanel" runat="server" Height="50px" Width="125px">

    <%-- Default Chart --%>

    <chartfx7:Chart ID="Chart1" runat="server" RenderFormat=".NET">

    <Series>

    <chartfx7:SeriesAttributes />

    <chartfx7:SeriesAttributes />

    <chartfx7:SeriesAttributes />

    </Series>

    </chartfx7:Chart></asp:Panel>

    Report.aspx : this page work as startup page. this page calls javascript method (DisplayChart) on load event which in turns calls default.aspx for chart generation. 

    code:

    <html xmlns="http://www.w3.org/1999/xhtml" >

    <

    head runat="server">

    <title>Untitled Page</title><script language="javascript" src="./chart.js"></script>

    </

    head>

    <%-- Call to DisplayChart method (present in chart.js) on onload event of page --%>

    <BODY bgColor="#ffffff" leftMargin="0" topMargin="0" marginheight="0" marginwidth="0" onload="javascript:DisplayChart();">

    <form id="form1" runat="server">

    <div>

    Default Chart

    <table>

    <tr>

    <td width="100%" colSpan="2" align="center">

    <%-- creation of place holder for chart --%>

    <div id="placeHolder">

    </div>

    </td>

    </tr>

    </table>

    </div></form>

    </

    body>

    </

    html>

    chart.js : this file contais DisplayChart method, which calls CreateChartForOneRow method, which will call defaul.aspx for chart. after geting reply from default.aspx, reply will be parsed by getfile method and responseText will added to innerHTML of place holder available in report.aspx

    function DisplayChart()

    {

     

    //Chart div is accesseddisplayObjArea = "";

     

    displayObjArea = document.getElementById("placeHolder");  //getting place holder element from report.aspx

     

    if(displayObjArea != null && displayObjArea != "")

    {

    chartSectionDiv = document.createElement("div");  //creating chart sectionif(chartSectionDiv != null || chartSectionDiv != undefined)

    {

    chartSectionDiv.id =

    "chartDiv";tableObj = document.createElement("TABLE"); //creating table for chart

     

    tableBody = CreateChartForOneRow(); // calling CreateChartForOneRow for table body

     

    tableObj.appendChild(tableBody); // attaching table body to table

    chartSectionDiv.appendChild(tableObj); // attaching table to chart section

     

    displayObjArea.appendChild(chartSectionDiv); //attaching chart section to place holder

     

     

    }

    }

    }

     

    function CreateChartForOneRow()

    {

    var tableBody = document.createElement("TBODY"); // creating table body for chart

    var trObj = "";var tdObj = "";

    trObj = document.createElement(

    "TR"); // chart rowtrObj.setAttribute('align', 'center');

    tdObj = document.createElement(

    "TD"); // chart columntdObj.setAttribute('align', 'center');

     

    tdObj.id = "ChartTD";

    tdObj.url =

    "default.aspx"; // calling default.aspx for charttdObj.ChartAttach = "1";

    str = getFile(tdObj.url); // call to getFile to parse the response

    tdObj.innerHTML = str; //attaching reponse to table

    if (tdObj.captureEvents)

    tdObj.captureEvents(Event.CLICK)

    trObj.appendChild(tdObj); // attaching td to tr

     

    tableBody.appendChild(trObj); // attaching tr to table body

     

    return tableBody;

    }

    function getFile(filename)

    {

    oxmlhttp = null;

    try{ oxmlhttp = new XMLHttpRequest();oxmlhttp.overrideMimeType("text/xml");

    }

    catch(e)

    {

    try{ oxmlhttp = new ActiveXObject("Msxml2.XMLHTTP");

    }

    catch(e)

    {

    return null;

    }

    }

    if(!oxmlhttp) return null;

    try{oxmlhttp.open("GET",filename,false);oxmlhttp.send(null);

    }

    catch(e){ return null;

    }

    return oxmlhttp.responseText;

    }

    when i am running this demo project chart is coming if its rendered as image but if chart is rendered as .NET then chart is not coming.

    i am following same flow in main project so if things works here it will work in main project also.

    Thanks

  8. chart does not load if render format is .NET control

    in Web Forms

    Posted

    Hi All,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    i have created interactiveChart.aspx which contains chart control and i am embedding interactiveChart.aspx into report.aspx by creating place holder for chart and using javascript.

    now my problem is if chart render format is image then chart is visible in report.aspx but if chart render format is .NET then chart is not visible.

    one more thing is that if i run interactiveChart.aspx directly(without embedding into report.aspx) then chart is visible with .NET render format..

    any idea what is going on and how can i solve the problem??

    pls, reply as soon as possible!!!

  15. Chart image generation problem..

    in Web Forms

    Posted

    hi,

    i am using ChartFX-7 to generate charts. the technology i am using is .Net 2005.

    till the point project was not published on IIS server the chart image was generated under project folder with the sub folder chartfx70/temp, but when i published the project on IIS server, the chart image was generated under Temporary Internet Files.

     Now, my problem is when i use authentication mode= "Forms" in web config  the chart image is not being generated.  i think it is because "Forms" authentication mode restricts the access to Temporary Internet File. so, is there any way to generate chart image elsewhere ? or is there any configuration setting by which access to Temporary Internet Files is possible using authentication mode="Forms"????

     pls reply as soon as possible!!!!
