BarChart Client Side

Posted by: jimmcgoldrick on 17 March 2020, 11:18 pm EST

    I am working in ASP.Net Wijmo with net 4.6.1 and am working through the Client Side Example given on your support web site ( . When I try to run the project it returns error "0x800a01b6 Object doesn't support property or method 'c1barchart'". This is obviously the old name of the widget, but I have referred to it correctly throughout my code as 'wijbarchart'. Is there a problem with the widget?

    Can you please confirm whether you are using ASP Webforms on Wijmo3. If you are using Webforms, then the BarChart should be referenced using c1barchart and if you are using wijmo3, then only you will need to use the wijbarchart method.

    Hello Ashwin
    It was created as a Bare Project, I'll try it as Web Forms, and then let you know the outcome.

    I can confirm that the same error appears with ASP.NET Web Forms.

    Hi Jim,

    Can you provide the sample you used to replicate the issue? It would be really helpful in finding the cause of the issue.

    You should have had my E-Mail and Attachment by now...

    I have got the project. I am working on it and will update you as soon as possible.

    Hi Jim,

    As I said in my first reply, if you are using BarChart on server-side (using ASP tags to create BarChart), then you have to access it on the client-side as c1barchart not wijbarchart. So, in your code, change all the references and let me know if this works.

    Before updating:

    After updating:

    Also, the ID may change on the client-side. The ID of an ASP control is assigned to the client-side by ASP itself. So, you will need to store the ClientID of the BarChart and then use it to reference it on the client-side:
    var id = '<%=C1BarChart1.ClientID %>';

    Yup, get that feeling of deja vu:
    '0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'c1barchart'
    The intellisense interpreter recognises wijbarchart() as a property too, but not c1barchart. Please clarify the next step for me.

    Hi Jim,

    I will follow the steps in the demo that you provided in the original query and will try to replicate the issue. I will share my observations with you as soon as possible.

    In the meantime, have you added the reference to C1.Web.Wijmo.4.dll assembly. If you did not, then add this assembly. It will be in the Extensions tab of the Reference Manager.
    After this, remove the following the scripts:
    <!--jQuery References-->
    <script src="" type="text/javascript"></script>
    <script src="" type="text/javascript"></script>

    <link href="" rel="stylesheet" type="text/css" />

    <!--Wijmo Widgets JavaScript-->
    <script src="" type="text/javascript"></script>
    <script src="" type="text/javascript"></script>

    and run the sample and let me know the results.

    Hi Again
    Have made progress of a sort.
    I am already referencing the library "C1.Web.Wijmo.Controls.45" and its associates.
    Removing the <script> references altogether got rid of the first error but lead to another.
    I seem to have a problem with the online example on the following page:
    If you go to the Point 7.b.2 and expand the Link 'To write code in Source View' -
    - this is completely wrong for the required coding. What should be the contents of the 'GetOrders.asmx' File. This seems to be the big problem with my code, and I cannot work round it. Please can you identify what has gone wrong!
    many thanks in advance,
    Jim Mac

    Hi Jim,

    I followed the steps in the demo and ran into the same issue as yours. I have fixed the issue and attached the updated sample for your reference.

    To resolve the issue, you will need to use c1barchart method and remove all the jQuery and Wijmo's reference, as I said earlier. Also, the source of GetOrders.asmx is incorrect. You may use the GetOrders.asmx file from the sample attached.

    I have forwarded this issue to the concerned team.

    Sorry for the inconvenience caused.

    Hi Ashwin
    First class laurels to that man! Saw that your example worked fine, so started looking for the differences compared to my (Non-Functioning) project. You were using .Net 4.8, so switched to that - no help. So looked in detail at the code. It went overlooked for a long spell, but then I noticed; in the GetOrders.cs and Orders.cs files, my code was surrounded by a Namespace directive, while yours was in the default namespace. Took the namespace out and - Cracked it, works like a charm now. Thanks for your gruesome lost weekend of groping for a solution.
    Many Thanks indeed,
    Jim McGoldrick
