How to get additional data and display in scheduler's date header

Question

Hi,I want to display appointments and additional info in date header such as weather just like the one in the demo here:

ASP.NET Core Scheduler Date Header Example - Syncfusion Demos

However, in the demo, weather data is hard coded. For actual usage scenario, where should I put ajax function to get the weather data for the current view?For example in Month view, I want to get weather data for current month and when user navigate to other month, get weather data for the selected month and render it in date header.I've tried using

navigating event to get weather data from server and renderCell event to add the weather info to date header but renderCell finished first before weather data is received in navigating event.

Hi RWEM, 

Greetings from Syncfusion support..! 

We have validated your reported problem “I've tried using navigating event to get weather data from server and renderCell event to add the weather info to date header but renderCell finished first before weather data is received in navigating event” at our end and suggest you use actionBegin event instead of navigating event. Please find the below code snippet. 





function ActionBegin(args) { 
    if (args.requestType === 'viewNavigate') { 
            // This block is execute before view navigation 
           // And you can get current view through scheduleObj.currentView  
        } 
 }
