    Guys, can someone help me out with the following error, "Unknown server tag 'asp:Chart'".
    I installed the MSChart control, have .net 3.5 running and modified the web.config to have the following tag between the <handlers> tag 
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

    and also the following between the <httphandlers>

    <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

    But still getting a problem when running my code with the above error. The code works on my local machine but when moved to run on SharePoint it will not.

    Thanks in advance

    Where do you have the <asp:Chart> control? is it in a webpart? user control?  What I am getting at is how do you have it inside sharepoint?

    also, do you notice anything in the event logs immediately after seeing this error message?

    Hi, Chochobeelai

     

         Thanks for your posted web config, it gives a lot of information.

     

         By your error message "Unknown server tag 'asp:Chart'", it seems that you have lost some config information under the XML root <pages></pages>

     

          Such as:

         

         <pages>  

          <controls> 

            <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 

            <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 

            <add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>  

          </controls> 

       </pages>

     

    Also, we have our Forum for MSChart,

     

    http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/threads which may give you further help.

     

    Hope this can help you.

     

    Best Regards,

     

    Aaron.
