Hi, 

For some reason the min and max dates are only enforced on the calendar popup, not in the scheduler navigation. 
The scheduler is first initialized without the min and max attributes, then I set them using setOptions() method. The reason being the restrictions are based on other parameters.
If I print the scheduler reference in the console, the min and max attributes are populated as expected. However as I said before, the restriction only applies to the calendar popup.

For example, if the max date is 2017-12-31 and the view is "month". If i click the 'next' navigation button, something is happening. I say it like that because the datsource is refreshing, but the displayed month is not changing to January.

I'm trying to explain my problem as best I can but honestly, haven't got a clue what going on. I hope you are able to help, I'll continue to investigate myself and hopefully will have more info for you when you reply.

Thank and kind regards, 
Grant

I have had very iffy results with setOptions on the scheduler... some things work, like toggling work hours, many things didn't, like setting selectability. I had to destroy and re-create my scheduler to set certain options when they changed.

You may have to destroy the scheduler (Here is documentation on this) and recreate with your new min and max.

Another approach that does not involve destroying and recreating your scheduler, is in the navigate event, check the date you are navigating to, if it exceeds the bounds of your min and max, e.preventDefault() to stop your scheduler from doing anything or scheduler.date(previousDate) to return to the date range the user was just on and pop up a warning or something saying that is as far as the scheduler goes. 

 

But I believe your issue is the destroying and recreating. To utilize the min and max date, you most likely will need to destroy and recreate with those options set. To avoid that, you can utilize my suggestion to catch and stop the user going beyond the min and max date in the navigate event of the scheduler.

Hi Grant,

Here you will find a simple Dojo implementing the described scenario. You will notice that initially, the Scheduler does not have a min or max date set. By using the arrow buttons on the toolbar the user can navigate to any previous or next month. On the Set min and max button click the min and max dates for the Scheduler are set. From that moment on the Scheduler allows navigation only to November or December 2017 (video here).

May I ask you to modify this sample, so it reproduces the issue observed at your end and send it back to us? This way I will be able to troubleshoot the problem locally.

Tyler, you are right, that there are number of cases in which the Scheduler widget needs to be destroyed and re-initialized in order to alter some of its configuration options. Nevertheless, setting the min and/or max navigation dates should be possible with the setOptions() method alone.

Hi Gents, 

Thanks for the replies, I've done some investigating and still havent been able to find a solution.

@Veselin, I've updates your Dojo example (https://dojo.telerik.com/ObUPAg/4) to a working version of what Im trying to achieve.I have a drop down list of users, each with a valid date range, although some dont have a max date, indicating that they work for an indefinite length of time. The idea is to set the min and max date of the scheduler to match the effective From/To dates of the users.

Setting the Min date does work, but only the first time. Resetting it only affects the scheduler, if you have already opned the calendar popup, its min date is not enforced

Is there a way to reinitialize the calendar popup with a new min/max?

Thanks, 
Grant

Thanks Veselin,

Your solution to setting the min/max on the calendar widget is great. I've made some slight improvements to your demo (https://dojo.telerik.com/ObUPAg/8) though.

I've updated the max date to be conditional on a null since the data that I used is actually from a remote source.
You used $('.k-scheduler-calendar').getKendoCalendar(); to get a reference to the widget. I have found though that the KendoScheduler does have a 'calendar' field (like dataSource and resources) that contains a reference to the widget, but it only exists after the widget has been initialized, it seems simpler to use that.

Perhaps this field should be documented?

Thanks for you time and help.

Hi Grant,

Thank you for the improvements on the sample. Also, your suggestion to include in the documentation the calendar field of the Scheduler makes perfect sense. As a small token of gratitude for helping us improving our documentation I have updated your Telerik points.
