Hi,

Am loosing control on appointment when am trying to drag and drop appointment on schedular control which as scrolling. It works fine in IE and problem lies with Firefox and Chrome browsers.

To produce this issues open below link in Firefox
http://demos.telerik.com/aspnet-ajax/scheduler/examples/outlook2007/defaultcs.aspx
Hope your schedular is displaying Monday, Feb 02, 2009. Scroll down to view 8.00 PM time slot. Try to drag and drop "Media Planning meeting" to 8.00 pm and you will find the issue.

could you please help me to resolve this issues.

Thanks in advance

Thanks & Regards,
Sumanth

Hi all,

I am still having drag and drop issues with the scheduler day view in Firefox and Chrome, when the scheduler has vertical scrolling. When the scheduler is not scrolled (ie. it is at the start of the day), there is no problem, the appointments can be dragged around correctly. However when the scheduler is scrolled down, dragging an appointment results in an offset so the appointment jumps up above the point where it was dragged from.

I was aware that this is a known issue in these browsers, it is not a problem in IE. Has there been a resolution to this? I recently upgraded to the latest version of the controls Q3, but nothing seems to have changed.

Anyone know about this?

Hello Ryan,

We haven't resolved that, yet. We will consider scheduling this for the Q2 2011 release.

Is there any update on this? It's been "under consideration" for some time now, and I'm not sure it's really cool that less than 50% of web users (current IE market share) can use this control properly.

Forcing clients to use IE for the scheduler to function properly is terrible. This is a great control, and it has awesome functionality, but why will you not improve support for other browsers? Performance is worst in IE ... clearly IE is declining compared to other browsers ... but still it is the only properly supported browser for this control?

What gives?

We are having the same issue as well.  It would be really nice to have this in 2011Q2 so we can re-enable drag and drop, which is large part of the purpose of using a visual scheduling grid.

We are also having major problems with this. The main reason we started using Telerik was the Scheduler, but still we can't really publish our new product as the scheduler is only usable on IE and because of javascript and rendering performance issues, pretty much IE 9 is the only version that works great.

I'm having that trouble too with firefox 5.0. In IE 8.0 it is working fine. My version is 2011.2 915

Would be nice a patch to this bug because it is a too old report.

Very true, we still didn't go live because of this issue... and management won't renew telerik unless it's fixed.

Agreed - we're having the same problem and it seems like this issue has been hanging around *entirely* too long. Has anybody come up with any workarounds that can help until this is fixed?

Ivan,

That certainly is some good news - I have a few questions, if you don't mind:

1. Does the internal build available now ("2011_1_614") address this issue, or will I need to wait until next week before a fix is available in an internal build?

2. I noticed that there isn't any CDN support and that it's not recommended that these builds go into production. Is there a chance of an officially supported, production-ready hotfix sometime in the not-to-distant future that we can deploy to production? This is a serious problem with a production app (which has a big trade show this weekend, incidentally) so we want to get something out there as soon as possible.

3. Are the internal builds time or feature limited? We have licenses for the Telerik components, but I assume these internal builds function more like the evaluation versions than the release versions. Is that correct?

Thanks, and I appreciate your prompt response to this inquiry.
-Chris

In our testing of the latest internal build from today (2011_2_1018) it looks like this issue is working in our case. What is your opinion on releasing this type of fix into production? We see the drag and drop issue as a big one for our users, and I know that your internal builds are not recommended for production use, but I could see justifying an exception in this case. Thoughts?

Also, can you say whether these fixes (for the drag and drop problem) will be included in the next production release of the Telerik controls?

Hello Chris,

To address your questions:

1) You should wait for this week's build;

2) You are right, we do not support CDN for the internal builds. The reason, apart from the official company policy not to do so, is for the life span of these builds -- each build supersedes the previous. You could, however, reference statically a previous official CDN, provided that there are no changes in the CSS / JS / images, which is highly unlikely.

Also, internal builds have not passed proper QA testing. True, they pass all the automated tests, which guarantees integrity and somewhat correctness of the code, but nothing can replace proper human tests with an eye on the detail.

This is why we generally do not recommend the use of internal builds, except in the cases of development and a development halting bug being fixed in that particular internal build.

3)  Internal builds are like regular builds in terms of limitation -- available both in trial and dev version. That said, apart from the CDN features.

4) In order to address your next question (and many similar for that matter) we have the Beta releases. They do have CDN support and have most features a Q release will have. They are generally a preview of what's coming next and ideally, the difference between a Beta and a Q release would be minor bug fixes.

That said, a Beta should be out next week.

Hi Denis,

 
We have spent a lot of efforts in fixing this issue so far and its functionality have been improved since the last post in this thread. Currently the only known issue that have left is that in Chrome when an appointment is being dragged and RadScheduler is scrolled after that the appointments sometimes are "frozen". The other known issue is happening only in the MultiDay View in some specific time slots.

Right now we are working on fixing these behaviors as well. If you are observing any other unusual behavior please try to reproduce it on some of our inline demos and send us a video of it so we could observe it and count it as well. 

Kind regards,
Plamen Zdravkov

Hi Plamen,

Drag and drop   from grid to scheduler  does not work  in Chrome browser if browser zoom level is  not equal to 100%.
If I adjust zoom levels(zoomIN/ZoomOut)  in Chrome browser, and drag and drop a ticket from grid to scheduler,  new appointment isnot created, I do not see any response in scheduler.


http://demos.telerik.com/aspnet-ajax/scheduler/examples/draganddropintegration/defaultcs.aspx?product=scheduler

How do I fix this issue, Is this a known bug?
Thanks,
Prava

Hello Prava,

 
We have already inspected this issue and it seems to be a bug in the drag and drop functionality of  Chrome browser itself-it is not getting the proper drop DOM element when the zoom is set to particular  amount.

Hope this will explain the issue.

What about touch drag and drop? I can drag and drop using a mouse, but on a touch screen monitor, drag and drop doesn't work.

Hello Steve,

 
Would you please share what is the exact device and browser that you are using and if the described behavior can be observed on this on-line demo as well so we could inspect the issue once again and be more helpful.

Hi Plamen,

I tried it on all the online demos to be sure it wasn't a setting that needed to be turned on or something like that. I can't drag and drop any of the events from one slot to another. i opened a support ticket for this yesterday, by request of another Telerik support person.

I'm using Dell PC, Windows 8, IE10 and Dell touch screen monitor.

I received a response from support that this is a bug and they are going to look into it. Please refer to ticket # 732381.

Hi Steve,

 
We have inspected the issue with RadScheduler in touch devices with Windows 8. Under mobile browsers it is designed to work with so called long touch and the in built context menu in order to insert, update and delete appointments or show the advance form as for example it can be observed on this on line demo. In order to be able to observe the default context menu you will have to enable it in the mark up.

As for the drag and drop functionality -unfortunately it is currently not working properly but we will make our best to fix it in short period. Currently the functionality is not stable but yet it is working in some browsers-FF the appointment can be dragged with one finger, in Chrome a drag can be achieved by tapping with two fingers on an appointment and then taping with on finger on other time slot, and in IE unfortunately dragging can not be achieved at all.

Plamen
