Unexpected Number When Opening Add Event Dialog

Asked by Chase

I am following the tutorial for adding an event to the scheduler. I am doing it slightly different however; I am using code behind to call the javascript function that will open the dialog.

Page page = HttpContext.Current.CurrentHandler as Page;
page.ClientScript.RegisterStartupScript(typeof(Page), "Test", "<script type='text/javascript'>timeRangeSelected(" + e.Start + ", " + e.End + ", " + e.Resource + ");</script>");

This calls the javascript function `timeRangeSelected`

function timeRangeSelected(start, end, resource) {
var modal = new DayPilot.Modal(); = 60; //This is where the modal is positioned.
modal.width = 600;
modal.height = 500;
modal.opacity = 70;
modal.border = "10px solid #d0d0d0";
modal.closed = function () {

//update the scheduler now that the modla has been closed.
modal.showUrl("NewEvent.aspx?start=" + start.toStringSortable() + "&end=" + end.toStringSortable() + "&r=" + resource);

Inside my Scheduler I have the TimeRangeSelectedHandling to Postback so the code behind will execute. The reason I am using the code behind is because I was to set the date of the my datepickers to the time range selected (the user wont have to input a date or resource).

If I set the TimeRangeSelectedHandling to javascript the dialog will appear and I can add an event (but not set the date or the resource to what the user selected in the time range).

If I have the TimeRangeSelectedHandling set to PostBack I get the following error in the console:

"Uncaught Syntax Error: Unexpected Number"

on this line:

<script type='text/javascript'>timeRangeSelected(4/13/2015 12:00:00 AM, 4/19/2015 12:00:00 AM, 106);</script>

I think maybe has something to do with the format that the date is in? Any help will be greatly appreciated.

You need quotes around the parameters so it produces something like this:

timeRangeSelected('4/13/2015 12:00:00 AM', '4/19/2015 12:00:00 AM', '106');

Try this:

page.ClientScript.RegisterStartupScript(typeof(Page), "Test", "<script type='text/javascript'>timeRangeSelected('" + e.Start.ToString("s") + "', '" + e.End.ToString("s") + "', '" + e.Resource + "');</script>");

This will convert the strings to ISO 8601 format (yyyy-MM-ddTHH:mm:ss) and add single quotes.

Then change the last call in the function to add the parameters to the query string without modification:

modal.showUrl("NewEvent.aspx?start=" + start + "&end=" + end + "&r=" + resource); 

Let me know if it didn't help.
