Allow creating of recurring tasks

In the RadGanttView implament filter functionality similar to RadGridView.

Make it possible when exporting the content of the control to be able to set its Width to fit one page's Width.

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

It would be useful if the control takes advantage of the RadSpreadProcessing, RadPdfProcessing and RadWordsProcessing. This will allow developers to easily export the control's contents to the desired format. Currently it is possible to export the control's content as images. 

More details about the available RadGanttView exporting could be found here:

- For Silverlight - http://docs.telerik.com/devtools/silverlight/controls/radganttview/features/exportingsupport

This property describes how exactly a cell in the Grid to go to edit mode. Its could be a Click, DoubleClick, Enter, F2 etc.

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

Hi,

I have recently been trying to implement a "split tasks" feature you would find in common Gantt packages, but Telerik doesn't support this out of the box. It would be great if this was supported, as modifying it ourselves comes with some level of risk, and may also be affected when we upgrade between versions.

Thanks.

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.

The Width of the ColumnDefinition is not updated after resizing it via the resizers.

The user should be able to create and add footer rows in RadGanttView in order to be able to summaries the data of the column above.

If a task is partially visible in the Timeline area, it should be bring into view when is selected by default.

If you edit a cell and directly change to another row in the TaskEdited event the TaskEditedEventArgs holds the old Task value before the editing.

The RadGanttView should provide a way to style the dependencies between the highlighted tasks. When the highlighted tasks are provided via HighlightedItemsSource property its would be nice if the relations could be styled  too.

When scaling RadGanttView control in order to print the visible area in one page width only, extra empty pages are generated.

If the following steps are performed:
- Hold the Ctrl keyboard key
- Highlight a task by clicking it with the mouse
- Highlight a second task
- Release the Ctrl key
- Click the first task again

Cause the second highlighted task to still be highlighted.

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.
