WPF Gantt Package / Re: Scrolling in FlexyGantt
« Last post by Rajagopal on July 27, 2020, 04:58:13 PM »
Hi Jan,

Thank you for your patience. In the reference sample, the content scrolling (scrolls per item) is enabled by default in the "DataGrid.xaml". You can simply set this "CanContentScroll" value to false like this,

Code: [Select]
<Setter Property="ScrollViewer.CanContentScroll" Value="False"/>
Note: Currently we don't support Virtualization and Overlapping features together.

Thanks,
Raja.

Jan,

We are looking on this. It will be more helpful if the reference sample is shared with us.

Thanks,

WPF Gantt Package / Scrolling in FlexyGantt
« Last post by tim on July 14, 2020, 07:15:48 AM »
Hello,

we are using the FlexyGantt with RowHeightBinding (from the sample OverlappedTasksChangingRowHeights) and without virtualization.
A while ago one of our customers complained that the gantt only scrolls per item vertically so if there is a row with many overlapping tasks (so that the row is higher than the screen height) they cannot see the tasks at the bottom.
We added VirtualizingPanel.ScrollUnit="Pixel" to the FlexyTable which solved the problem.
We now need to activate virtualization because of severe performance problems but if we activate it (like described in the user guide) the left and right side (tree and gantt control?) get out of sync while scrolling vertically.
It looks like the left side scrolls per pixel while the right side still scrolls per item.
Is this a bug or is there another way to achive the desired behaviour?

I can provide a modified version of the sample ServerStatusWithHugeData if needed.

Best regards

Francesco,

We have introduced new PreventHorizontalShifting option to prevent horizontal movement of taskbars. We have sent the latest assembly(v9.0.45.11) from our support mail, make sure to get it.

Code: [Select]
public MainPage() {
InitializeComponent();

// prevent horizontal shifting by setting true. Default is false.
ShiftTracker.Global.PreventHorizontalShifting = true;
}

Thanks,
Raja.

WPF Gantt Package / Re: Drag Task over Working hours

Hi Raja,
unfortunately your solution is good but I found a problem:
if in the ShiftTracker_BeginVerticalDrag event I cancel the Drag operation (with args.Cancel=true) it starts again the Horizontal Tracking.
Then I tried to call the ShiftTracker.Global.EndTracking in the BeginVerticalDrag or in the VerticalDragOver event handler but an System.NullReferenceException occours (the exception is not catched in the VS)

Have you any suggests?
Thanks
Francesco
