Gantt not rendering when deployed to IIS

There is no limitation built into the demo that would prevent deploying it on IIS.

The rendered code (ASP.NET WebForms) should have three parts:

1. The empty div with id set to the ID of the control. You will find it at the place where you put the control.
2. References to the JS libraries, loaded from URLs that include "/WebResource.axd?"
3. JavaScript initialization code. You will find it at the bottom of the page. It starts with the assembly identification which looks like this:

<script type='text/javascript'>
/* DayPilotPro: DayPilot, Version=8.1.3460.0, Culture=neutral, PublicKeyToken=426941954f05e7fe */
...

The <script> section should list the settings.

If the Gantt control doesn't appear at all there is probably a JavaScript error that you will see in the browser JS console (Ctrl-Shift-I in Chrome, F12 in IE/Edge).

In Chrome you might see something like:

"Uncaught ReferenceError: DayPilot is not defined(…)"

or

"Uncaught TypeError: DayPilot.Gantt is not a function(…)"

This means that the libraries from part #2 were not loaded properly. Let the page reload with the Developer Tools enabled and check all WebResource.axd links in the Network tab of the Developer Tools.

The response should contain JavaScript code. You might see a server-side error instead, maybe an exception description. The error message should tell you more about the cause - most likely it's some kind of IIS misconfiguration.

Hello, you are right, there is some javascript errors related to the webresource.axd:

SCRIPT1028: Expected identifier, string or number
File: WebResource.axd, Line: 1, Column: 23800

and then a 2nd one in my page:
function gntPlan_Init() {
var v = new DayPilot.Gantt('gntPlan');
* Object doesn't support this action

I don't see anything weird in the network tab, looks like all the files are transferred properly, 5 webresource and 2 scriptresource.

Is your IIS configured to automatically minify output with "text/javascript" MIME type? That would explain the different behavior on your local server (I assume the DayPilot.dll is the same).

DLL is indeed the same, im using the "publish" option of visual studio 2015 to copy the files over to the inetpub folder of the destination server.

I haven't enabled any settings to do minification, I did a quick look around in IIS and couldn't see any settings related to this.

I also tried recreating the site from scratch, same result.

Could you please send the content of the WebResource.axd file (that one with the error) to support@daypilot.org? I'll try to compare it with the correct one.

Thanks - the script seems to be fine (i.e. it's not modified).

Anyway, the extra comma is removed now in the latest sandbox build (8.1.3467):

http://www.daypilot.org/sandbox/

Could you please give it a try?

the rendering seems to work better however I am getting new error and some of the formatting(like row height) seems a bit off

heres the new error:
;DayPilot.JSON.stringify=function($1x,$2L,$2M){***if(JSON&&JSON.stringify)***{return JSON.stringify($1x,$2L,$2M);}
I added the *s to point out where it breaks, the message is "'JSON' is undefined. "

The JSON object should be available in IE8+. It looks like you are using IE to access the IIS site and the IIS URL is in the list of sites to be displayed in compatibility view. Or the IIS site is using a master page with no doctype specified (making the browser run in quirks mode).

That would explain the comma error (modern browsers don't mind that), the broken dimensions and the missing JSON object.

Could that be the problem?

that solved it, the site was in out intranet zone and we have a gpo that defaulted compatibility view. I've added a meta tag to default to edge and everything is working fine now.

thanks!

Great, thanks for posting the solution!
