[Solved] Performance issue

[Vivek]

Hi Team,

I have created a test project to have 10 users with 600 Appointment for each users.
when go to the timlineview to today view or any view its taking to much time to load.

Please let me know what we can do to remove this performance issue. or let us know how many Appointment a user can handle?

I am opening the view after a button click even i need to wait for a while to load the view with data first time.


here is my code.

Hi Team,

I do't know why no body is replying . 

Please let us know if you have any solution.

Hello Vivek,

We are sorry you are experiencing performance issue with our control. We are constantly trying to improve the performance of RadScheduleView. We will do our best to improve it for your specific scenario in our future releases.

Meanwhile, to improve the performance with so many appointments I would suggest a few things:

1. You can edit your Appointment Style. Simplifying it will significantly improve the performance of your application.  How to edit the Appointment Style you can read here. Also you can find attached a sample example.
2. You can load appointments depending on the visual range of RadScheduleView. How to do this you can find here.

Do not hesitate to contact us if you have any questions.

Regards,
Ivo

Hi Ivo,

I am looking for this now could you please guide me in right direction. If you have sample codes do send us.

Please check this.

Hi Ivo,

Please find the image as an attachment.

I am looking out for pager and pages in dropdownlist which will have users inside the dropdownlist.

for an example suppose you have 25,50,100 digits is there in dropdownlist, by default 25 users should be selected and it should show the jobs/appointment for the corresponding user. now if user selects 50 now it should show 50  users jobs/appointment on the view.

and the same operation should be done if you page form number please see the image.

Please guide me in right  direction.

Do pass me the sample codes if you have.

Thanks,
Vivek.

Hello Vivek,

You can find attached a sample example demonstrating how to create resource pager. Combining the resource pager with loading appointments on demand will greatly improve performance for cases with lots of appointments. 

Also I would like to ask you to post a single question in a single thread . Posting the same question in several threads will only slow us with our answer.

Kind regards,
Ivo
