The height of the GroupTickContainter, MajorTickContainter, MonorTickContainter cannot be changed at present.

Look the attach file,when resize the GanttView  column （left or right） reciprocation,the colum resize line is not align to the grid column line.
just when the DPI is exceed 100%, Appears.

You can find a runnable example showing how to populate the control from a database in the ConnectToDatabase SDK example - https://github.com/telerik/xaml-sdk/tree/master/GanttView/ConnectToDatabase.

There are two scenarios where the issue can be seen:

 - at startup when the ColumnDefinition’s Width is set to AutoHeaderAndContent its Width is rendered incorrectly;

- when you change the PixelLenght;

The issue could be observed in the attached short video

When the Window OS DPI setting is set above 100% resizing the grid portion's columns with their resizer controls leads to unresponsive UI and possible application crash.

If you have a GanttTask(s) added in the RadGanttView control, and the DPI is higher than 100%, the UI is almost unresponsive. Also, the newly added tasks are not visible until you resize the control.

The selection shown in the exported image is wrong in some cases. This is reproducible when you select multiple items (more than 2).

To work this around you can clear the selection before the export and then re-select the items. To do this you can use the SelectedItems collection of the RadGanttView control.

Add the possibility of TimeRuler's TickIntervals to respect the CurrentUICulture's time format.

The scrollbars in RadGanttView are always visible for timeline part. They should be collapsed when the content of the timeline fits on the screen.

Make it possible to use a CollectionViewSource and its Filter etc. built-in features with the RadGanttView control's TasksSource.

Add a mechanism to determine the position of the main resizer and one for setting it. This will allow the users of the control to persist its position and reload it later.

As a user of the control I want to be able to highlight grid and timeline rows in different colors, depending on the data inside the task so that the user can easily see tasks with special properties.

As a <role> I want <ability> so that <benefit>.
