RadGantt needs to considering "working time" when plotting.

You have workDayStart, workDayEnd, workWeekStart, and workWeekEnd which appears at this point to only control UI.

My suggestion is as follows: let's say I have a task that is 8 hours long in duration(does not appear that I can set the duration on a task, its readonly), I set the task StartTime to be Friday 1PM and EndTime to be Friday 9PM, hence 8 hour duration, I would expect the control to consume its own configuration(defined by params above) and know that from 5PM - 9PM are not working hours, nor is Sat or Sun and to paint the additional hours on Monday from 8AM - 12PM.  This is how MSProject and other gantt controls operate.

Essentially I don't want to give you an EndTime, I should be able to simply set the StartTime and provide a duration and you would consume the working hours configuration and figure out the EndTime to plot.

I am migrating MS Project Documents into Line of Business application into web pages. Which means everything MS Project can do, my client expect the telerik controls to do!

What I require is 'Go to' Date, where by the radGantt display can scroll to that position (eg like jumping to a # location)
This will allow the implementation of 'Go to 'Today'
This will allow the implementation of 'Go to 'dd/mm/yy'  
Where the date in in the center of the page, with an optional line (you are here) indicator. See https://www.officetimeline.com/plus for ideas.

I was trying out the RadGantt control. Noticed the following

1. There is no validation on the dependency - for example, if I have set the dependency to "Start After" parent task, then should it allow me to enter CompletionPercentage? does not make sense.

2. If I extend the end date of the predecessor, then there is no option to automatically update the dates of all successors. This means that I have to manually adjust all the subsequent dates. Doe not make sense.

These were noticed on the demo application on the web. If these features exist, then please point me to the relevant demo.

Add a vertical line that indicates the current date in the timeline. You will also have to option to scroll to the current date when the control is first loaded, or changing views.
