I would like to voice my opinion for an ASP.NET Scheduling Component based on the requested feedback from the following post:
http://www.telerik.com/community/forums/thread/b311D-tbdhb.aspx

We are currently researching components for use in a custom developed company internal scheduling tool that will be used by multiple business units. Based on this we have come up with the feedback listed below.

Key Requirements

• AJAX support
• Robust client-side object model
• Solid drag and drop support
• Recurring tasks/appointments
• Task/Appointment alerts
• Style look and feel via CSS
• Cross browser compatible (IE -- 6 & 7, Firefox -- PC & Mac)
• Concise HTML markup
• Not ViewState dependent.
• Support for database storage a must (other storage types a nice to have)

Scenarios

• Day, Week, Month views.
• Ability to show tasks/appointments for multiple resources on the same view.
• Drag tasks/appointments within a day and use drag to change start/end times.
• Drag tasks/appointments between days.
• Show multiple taks/appointments with varying colors.
• Have tasks/appointments with multiple states (e.g. published - viewable by all and planned - viewable only by some).

NOTE: Since we are currently evaluating other controls we do have any real world experience with these, but here are some initial thoughts after looking at the following.

Other Controls
- WebPlanner by TMSSoftware
   - Lacks AJAX support (beta with ajax available 4/2007)
   - Have focused attention on being lightweight.
- WebSchedule by Infragistics
  - Extensible data provider model.
  - Runs with enableviewstate='false'.
  - Lacks drag and drop across days in a week or month view.
- WebSchedule by ComponentOne
  - Lacks drag and drop
  - Not sure it supports displaying multiple resource schedules at one time.
 
Please let me know if you would like additional information from me.

Hello Paige,

Thank you for the extensive feedback. Your input is much appreciated (and the respective telerik points are added to your account)

All of you comments will be taken into consideration in the development process. We are looking forward to hearing your feedback once the beta bits are out. Please stay tuned.

Regards,

Wanted to let you all know that we have been doing an in depth examination of the WebScheduler from ComponentGo control in relation to our scheduling needs. So far this is the closest thing to what we are looking for that we have found. As it provides the ability to display multiple people and their scheduled items at once across multiple views. However, some of the AJAX and other pieces are not as robust as we would like.

I saw the Quest the announcement yesterday about the new RadScheduler that will be available as part of the new Prometheus suite of controls. However, according to a blog post by Todd Anglin on TelerikWatch it doesn't sound like the RadScheduler will be available for a while yet? True.

If so is there anyway to evaluate an early version of this control. We have been very impressed with the controls that you all produce and would love to get an early look at your control to see if it will meet our needs and provide feedback about the control. Thanks in advance.

Hi Paige Cook,

We have just announced that we are already working on a Scheduling tool and it will be ready for prime time in a couple of months. The first public beta release is expected towards the end of May.

Thank you for your patience.

Sincerely yours,

Hi
I have had a significant number of requests for an online calendaring interface where multiple people can sync their Google/Outlook (desktop and mobile) and actively compare personal calendars for shared times of availability (e.g. 5 people need to meet, they select a start date and end date to be uploaded from their calendar and then compare all to find shared times of availability). 
Yah, I wanted the image editing functions too...
Cheers
John
