I have combined these two requests in a single ticket as I feel that they are closely linked, and the second does not make much sense without the first.

Stretch option for Gantt task visualisation

It would be very useful if the user could specify a 'stretch' option for the horizontal width of the Gantt which causes the task visualisation to fill all of the available space (by increasing the PixelLength). The Gantt chart looks very strange when a fixed PixelLength results in a large amount of empty space, particularly as most other containers can be resized. It can also be difficult to guarantee that the Gantt chart fills all available space when it is inside a resizable component.

Ability to move resize control when both sides are at their 'desired width'

Currently, the resize control which separates the column data on the left from the visualisation of the gantt tasks on the right cannot be moved when both sides have reached their 'desired width'. However, this is not intuitive as other types of Telerik controls (notably the GridView) allow the width of components to be increased or decreased by clicking and dragging left/right, even if an absolute width has been set in the XAML.

Anticipated behaviour:

• When dragging to the right, it seems logical to start expanding the width of the text columns on the left.
• When dragging to the left, if the Gantt visualisation is already at its desired width, the PixelLength should be increased so that the Gantt fills all the available space.

I recognise that these features may not be desirable for all users, so it would be helpful if these were features that could be toggled on/off.

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.

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.

This reproduces with recurring tasks.

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.
