Hello,

i am currently evaluating kendo ui and i am in a struggle while implementing the following:

Since i have many resources and events i want to use server filtering.

The example from the link below works great for event filtering.
https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/filtering/server-filtering


My problem is i would need the resources also to load dynamically from a datasource(with start/end set parameters)
But since the resources seems to be loaded before the scheduler view seems to be ready i do not have the start/end variables.

Changing the resources after the scheduler is loaded and perform a scheduler.refresh does not work.
It is showing the changed resources only after an action on the scheduler (change view, click on today)

Do you have any hints for this?

Thank you and best regards, Alex

Hello Alex,

You are correct. In order to filter properly the resources in the Scheduler, you will have to wait for the view to be initially loaded. Then you should force read on the resource DataSource and after the response has been received, you should reset the view:
var dataSource = scheduler.resources[0].dataSource;
dataSource.one("change", function() {
    scheduler.view(scheduler.view().name);
});
dataSource.read();

Similarly to the events server filtering scenario, you should pass the start and end date along the resource Read request, so you will be able to filter them on the server.

To properly catch the moment, when the Scheduler view has been loaded and the start and end dates are known, you could use the Scheduler dataBound event. In order to prevent an endless loop, you could use a flag, which would be set to true in the navigate event of the widget. Only in that case the Read on the resources DataSource should be forced.
