    I have a scheduler defined like this:

        .StartTime(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day))
        .Views(views =>
            views.WorkWeekView(workWeekView => workWeekView.Selected(true));
        .DataSource(d => d
            .Model(m =>
                m.Id(f => f.Id);
                m.Field(f => f.Title);
                m.Field(f => f.Start);
                m.Field(f => f.End);
                m.Field(f => f.Description);
            .Read("Read", "Scheduler")
            .Create("Create", "Scheduler")
            .Destroy("Destroy", "Scheduler")
            .Update("Update", "Scheduler")



    When I load my page, my data loads on the scheduler but I get this error on console:

    Uncaught TypeError: Cannot read property 'replace' of null
        at Object.eval [as tmpl0] (eval at compile (kendo.all.js:194), <anonymous>:3:152)
        at Object.eval (eval at compile (kendo.all.js:194), <anonymous>:3:645)
        at d (jquery.min.js:2)
        at r._createEventElement (kendo.all.js:91346)
        at r._renderEvents (kendo.all.js:91436)
        at render (kendo.all.js:91504)
        at init.refresh (kendo.all.js:100801)
        at init.d (jquery.min.js:2)
        at init.trigger (kendo.all.js:124)
        at init._process (kendo.all.js:7050)

    Then when I click on the scheduler to add a new task on tabs "Work Week", "Week", "Month", no popup to add new Task is displayed.

    Are you able to provide a runnable example? I am not familiar with SignalR and don't know how to get your scheduler running in a dojo. 


    The reason no pop up shows up to make a new task is because your scheduler already crashed. The Uncaught TypeError has broken your scheduler, so now things may behave with undefined behavior, or not function at all.

    Hi all,

    Here you could find an example of the Scheduler usage with SignalR:


    In addition, here are our demos on the topic for the jquery widget and the MVC wrapper:



    Regarding the Cannot read property 'replace' of null error, everything seems to work as expected on my end. You could send a support ticket with attached sample project, so that we could investigate what's causing the error.
