Sharepoint and MSChart control?

    Question

  • 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

  • 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,

    Hope this can help you.

  • 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?
