    Database save problem - Binding error ?
    Radscheduler is not much use if i can't load and save data...
    on load the scheduler data is not present in User 1 to User 4.
    When I save Data the appointment disappears but one good
    thing if I drag a new appointment from say User 1 to user 3
    that change shows when pulling up the appointment!
    Could you please give me some assistance i have tried but
    have failed.
    I re-bound the SchedulerBindingDatasource, and that was
    un successfull... Thank you for the wonderfull products!
    (Any user to user help would also be of help)

    Many Regards,
    Jeffery R Link

    Hello Jeff,

    Thank you for writing.

    I have investigated the code you have posted, however, I cannot identify the exact issues in it since there is no actual binding demonstrated in your snippet. Again, I would kindly ask you to open a new support ticket which describes the problems you are experiencing and send us a sample project which demonstrates the full source code of your approach. This will let me get familiar with your case and provide you with adequate support.

    Meanwhile, you can check the Data Binding Walkthrough help article which explains data biding of RadScheduler step-by-step. You can also refer to our Data Binding example in our Demo Application.

    Thank you for your understanding. Looking forward to hearing from you.

    Kind regards,
    Ivan Todorov

    Q2’11 SP1 of RadControls for WinForms is available for download (see what's new); also available is the Q3'11 Roadmap for Telerik Windows Forms controls.
