In project management it´s very important the possibility to save a baseline, because is the reference to compare project performance. 
Something like "save current task list with a specific name, sample: baseline_first-planning-date". 
After sometime it´s possible to save new baseline with all changes of dates and other columns. 
At this moment with two baselines it´s possible to compare the project performance, showing two gantt with different colors. 
I believe this is a great improvement. 
Thanks

I would like to use the RadGantt control in combination with my own RadWindow that would pop up as an edit control when clicking on a row in the treeview control of that object. There currently appear to be no client side events on the treeview. 

I would like the treeview to have a third mode that is not exactly "ReadOnly=True" or "ReadOnly=False", but would allow the row to be highlighted on click. The row data would not be editable, and clicking anywhere in a row would raise a client side event that I could trap.

Thanks for considering.

Add the Pan and Zoom feature found in HTMLChart to Gannt. 
#1 This allows the project timelines to be zooned into and out of on the Right Hand Side, and on the Left Hand Side zoom into the 'bill of material' that makes up a Milestone to just milestone view.
#2 The Pan allows you to sweep along a long gantt chart, across days in a year. On a tablet you can just flick to the left and right to see what jobs you have on.

I have two dates for a Task[Eg: Plan Dates & Actual Dates]. I want to show both plan and actual dates in same row, both with different colors. Below I have attached an image for reference.


To show both Planned and Actual dates(if any) for a particular single task on the same row with different colors for both.

I need a context menu when user right click on particular task. Is it possible?

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!

I would like features as seen in https://www.officetimeline.com/plus
Which means I can summarize  the status of a project.
Which means I can use the mouse wheel and the 'Ctrl' key to zoom in and out of a project. 
Initially this would be like changing from 'Day' view all the way thro to 'Year' view,  but unlike pressing this buttons, I am still centered on in on that date much like in https://soundcloud.com/explore but its not music but a date on a timeline.
So if SoundCloud was for Project timelines that would be good.
This also have cross over for the Scheduler calender Timeline.

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

In your RadGantt controls, the Left hand side of the control is perceived to be a RadGrid this it is expected to have the same affordances of radGrid.
Which means that I expect the 
<CommandItemSettings ShowAddNewRecordButton="false" />
to work.

Which means I can apply all my learning of radGrid to the left hand side of radGantt.

On either a RadGrid or RadGantt  I would like to be able to rotate the headings just like in Excel. 
An example is a heading like 'Days' but the actual value in that column is no bigger than 99.  
Another example if that the heading has a question, and the cell a check box.

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.

We are missing the following navigation options (like the ones the RadScheduler has): go to the previous, next period (day/week/month) or go to a specific date.
Also, the views should show only the specified period (so the week view should show the current week by default). Now, if we have a task that started last year, even the day view shows several months of data.

If the RadGantt custom column could be a type of "Rich Text", then we could insert any html including link buttons (e.g. edit task ),  Icons ( e.g. tick for task complete), or rich text in red, green or whatever. 
We would also need the data_bind event available to populate the custom field. :)

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.
