RadScheduler for WinForms with OpenAccess for DataBinding crashes with System.NotSupportedException or doesn't save changes

[Nihat]

Hello,

i'm trying to use the RadScheduler for WinForms with OpenAccess for databinding.
When i try to make a new appointment it chrashes with the System.NotSupportedException.
I made a small basic sample app by using the RadScheduler Binding-Demo and this topics:
http://www.telerik.com/help/openaccess-orm/openaccess-tasks-howto-radscheduler-win.html
http://www.telerik.com/help/winforms/using_a_data_provider.html
See sample app: "RadScheduler OpenAccess WinForm"

Edit: i see that i can't post a sample app here, only pictures. Is it possible to give you the sample app somehow, so you can reconstruct the issue?

The StackTrace is:

System.NotSupportedException wurde nicht behandelt.
  Message=Die angegebene Methode wird nicht unterstützt.

Kind regards

P.S. it's an urgent issue, cause i've to make a prototype soon to decide if we will use Telerik for the comming project.

[Nihat]

i found the reason for the error.

In the "MyAppointment"-class of the RadScheduler Binding-Demo there is this code.

public List<MyResource> Resources

{

    get

    {

        if (this.resources == null)

        {

            this.resources = new List<MyResource>();

        }

 

        return this.resources;

    }

}

this part causes the error:

        if (this.resources == null)

        {

            this.resources = new List<MyResource>();

        }

Commenting this out solves the issue.

Perhaps you can tell me why?

Hello Nihat Özkan,

Thank you for writing.

You could use Open Access, but not as a provider for RadScheduler for WinForms. For this case you have to take the business object from the Open Access object and map it to the RadScheduler for WinForms. You could read the available documentation concerning the topic of Binding to Business Object and the articles that you have found concerning the Open Access usage. I hope that this will help you.

Feel free to contact us in case you have further questions.

Kind regards,
Dobry Zranchev
