Hi Telerik Team,

I have defined custom event template for my scheduler. When I move event in the scheduler I am getting errror as "Uncaught TypeError: Cannot read property 'occurrenceByUid' of undefined".

When I debugged the Javascript and found that the error is coming in the below code

(function(data
/**/) {
var $kendoOutput, $kendoHtmlEncode = kendo.htmlEncode;with(data){$kendoOutput='\n    ';var uid = target.attr("data-uid");;$kendoOutput+='\n    ';var scheduler = target.closest("[data-role=scheduler]").data("kendoScheduler");;$kendoOutput+='\n    ';var model = scheduler.occurrenceByUid(uid);;$kendoOutput+='\n   \n    ';if(model) {;$kendoOutput+='\n        <strong>Job Start:</strong> '+(kendo.format('{0:ddd M/dd, hh:mm tt}',model.start))+'<br />\n        <strong>Job End:</strong> '+(kendo.format('{0:ddd M/dd, hh:mm tt}',model.end))+'<br />\n        <strong>Job Details:</strong> '+(model.title)+'<br />\n    <strong>Job Address:</strong> '+(model.Address)+'\n    ';} else {;$kendoOutput+='\n        <strong>No event data is available</strong>\n    ';};$kendoOutput+='\n';}return $kendoOutput;
})

 

where the "var scheduler = target.closest("[data-role=scheduler]").data("kendoScheduler")" is undefined and the error is coming. Please help how to fix it.

Hi Team,

I want to add one more point for above error. I am using telerik tool tip for the scheduler event.

The above error is the from the tooltip script.

 So please let me know where I am wrong.

Hello,

From the provided information it seems that the scheduler object is not found when dragging the event outside the scheduler - you can improve the tooltip template as follows:

#var uid = target.parent().attr("data-uid");#
#var scheduler = target.closest("[data-role=scheduler]").data("kendoScheduler");#
#var model =  scheduler ? scheduler.occurrenceByUid(uid) : null;#

Hi Vladimir Iliev,

 Thank you for the solution.

This fixed the error but I found something new, the tool tip is displaying blank when there is no model. I do not want to show like that, is it possible to hide it when there is no model. 

 Please see attached screen for easy understanding

Hello,

In the described scenario the best way to hide the tooltip is to not showing it when dragging events. This can be achieved by improving the current filter as follows:

filter: ".k-event:not(.k-event-drag-hint) > div"
