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.

It'd be nice to have templatecolumns in the column definitions. Also that bound columns bounds to different properties other than expected, ie: Title, ID, etc. So for example I could implement different behaviors based on a gantt diagram.

<telerik:GanttBoundColumn  AllowEdit="true" UniqueName="colSelected" DataField="Selected" AllowSorting="false" DataType="Boolean">
            </telerik:GanttBoundColumn>

This should render a checkbox for example, but DataType="Boolean" its probably thought for Summary field.

I know this control is still on beta, but at least task selection would be nice to have.


Also I would like this control to be more performance optimized , In the project I want to implement it I need to draw quite a few tasks.

Thanks

Regarding RadGanttView (couldn't find it in the List)
Seems odd to me that you cannot override the default double click behaviour.
(in my case I would like to open a radWindow instead of entering Cell Edit Mode).

Couldn't find any event for it either client or server side.
This would be very useful if think, so I thought I try and request it :)
Both Task Click (SelectionChanged) and task double click should be accessible.
Talking about the grid part of the control.(left side)

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.

How can we plot planned Vs Actual on RadGantt chart? We need two rows in the Gantt for each task. The first row to show planned while the second row shows actual progress. Both Actual and Planned progress to be shown in different colors.

Sample output is attached for your quick reference.

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.

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.

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

Allow RadGantt to export the data to Excel

It will be helpful if we have import mpp (MS Project file) option instead of XML, this will ease users and they don't need to convert file to xml and than upload.
This is already done by other providers like bryntrum and i think it is a must as customers are suffering with export to xml and upload.

Hope telerik applies this suggestion!

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.

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!
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.
