Complex event validation in Scheduler

[Yongkee Cho]

In my device reservation app, each event must be validated to ensure that the selected device is available for the specified time range in the database. Custom editor with validation does not work in this case because we need to check the combination of device, start time, and end time together rather than validating them individually.

I’m considering using OnPopupClose to either save the event or reopen the editor with an error message if validation fails. Is this the right approach?

public async Task OnPopupClose(PopupCloseEventArgs<Schedule> args)
{
    if (args.Type == PopupType.Editor)
    {
        if (IsValidated(args.Data)
            await _scheduler?.SaveEventAsync(args.Data)!;
        else
        {
            AlertService.ShowAlert("Fix an error. Blah Blah");
            await _scheduler?.OpenEditorAsync(args.Data, args.CurrentAction);
        }

Hi Matteo Antonini,

We recommend not reopening the Schedule Editor event window again. If the validation fails, you can prevent the popup from closing by setting the Cancel property to true and displaying an error message to the user. Additionally, there is no need to call SaveEventAsync on popup close if you are using the Editor footer template. In this case, you can handle SaveEventAsync on your end. However, if the Editor footer template is not used, the event will be saved by default.

Please refer to the attached code snippet and sample demonstration for the solution. Try it out and let us know if you need any further assistance.

public async Task OnPopupClose(PopupCloseEventArgs<Schedule> args)

{

    if (args.Type == PopupType.Editor)

    {

        if (!IsValidated(args.Data))

        {

            AlertService.ShowAlert("Fix an error. Blah Blah");

            args.Cancel = true; // Prevent popup from closing

        }

 

        // Proceed with other logic if validation passes

    }

}
