Workaround: create custom GanttViewTimelineItemElement with special layout arranging the elements in depending on their parent`s final size. The attached project features a possible implementation.

Columns can automatically fill the entire width of the GanttViewTextViewElement . Just set the AutoSizeColumnsMode property  to Fill.

Add functionality to sort tasks alphabetically, by date, by progress.

To reproduce: click (mouse down) on a task but then release the mouse button off the task. It then stays selected even when I click on other tasks. You can repeat this over and over and end up with every task as "selected" as shown in the video.

Workaround:

 AddHandler Me.RadGanttView1.GraphicalViewItemFormatting, AddressOf GraphicalViewItemFormatting

Private Sub GraphicalViewItemFormatting(sender As Object, e As GanttViewGraphicalViewItemFormattingEventArgs)
    Dim taskItem As GanttViewTaskItemElement = TryCast(e.ItemElement, GanttViewTaskItemElement)
    If taskItem IsNot Nothing AndAlso taskItem.TaskElement.VisualState.Contains(".MouseDown") AndAlso Not taskItem.Selected Then
        taskItem.TaskElement.IsMouseDown = False
    End If
End Sub

How to reproduce: 
  this.radGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = Telerik.WinControls.UI.TimeRange.DayQuarterHours;
  this.radGanttView1.GanttViewElement.GraphicalViewElement.AutomaticTimelineTimeRange = true;
  this.radGanttView1.GanttViewElement.GraphicalViewElement.OnePixelTime = new TimeSpan(0, 0, 15);

Workaround: at the moment the Gantt control does not support an automatic timeline range for day quarter hours. The TimeRange.DayQuarterHours is similar to the half days and they should be handled the same way when in automatic timeline. If possible TimeRange.DayHalfHours 
this.radGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = Telerik.WinControls.UI.TimeRange.DayHalfHours;

Currently when you set the TimelineRange property to TimeRange.Week displays two elements (the TopElement with weeks and the BottomElement with days). There are cases where users want to display single timeline - only weeks, days, quarters or years independent of the second timeline.

The position of splitter should allow to be fixed while resizing the control. Users want to be able to set the splitter next to the last column of TextViewElement when resizing.

This event should be fired when a task is modified either by the graphical view or by the columns on the left side. In the arguments you should have access to the changed property.

To reproduce:
1) Open the Demo application >> Settings example.
2) Select a task and activate the editor for it.
3) Delete the task by clicking the button above.

It may be necessary to repeat the steps several times. The error is not reproduced immediately.

Release R3 2019 (LIB 2019.2.708)

The latest release of WinForms causes a fatal exception when adding an item to a BindingList that is used in a RadGridView and a RadGanttView.

The first time an item is added there is not issue.

The second time an item is added, the following exception occurs.

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.WinControls.UI.GanttViewBindingProvider.GanttTaskList.IndexOf(Object key)
   at Telerik.WinControls.UI.GanttViewBindingProvider.GanttTaskList.get_Item(Object key)

   at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e)

This is code that has not been modified for quite some time.  There has been no issue until the latest release.

I do not have time to try to create a simple example to try to reproduce the error at this time.  I will if possible.

For now, we are forced to revert to a previous version.

Release R3 2019

Please refer to the attached sample project and run it. Select a random item and press the button. You will obtain the error. If no selection is available, the item is removed as expected. 

Workaround: use Begin/EndUpdate block while deleting a record from the DataTable:

        Me.RadGanttView1.BeginUpdate()
        _dataset.Tables("Tasks").Rows.RemoveAt(2)
        Me.RadGanttView1.EndUpdate()

Release R3 2019 (LIB 2019.2.819)

Please run the attached sample project. Select one of the child tasks and click the button. The new task is expected to be inserted at the selected item's position. However, it is appended at the bottom as it is demonstrated in the gif file.

Workaround: rebind RadGanttView after inserting a new row to the DataTable: 

    Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
        Try
            If Me.RadGanttView1.SelectedItem IsNot Nothing Then
                Dim i_rowIndex As Int32 = _dataset.Tables("Tasks").Rows.IndexOf(Me.RadGanttView1.SelectedItem.DataBoundItem.Row)
                Dim i_datarow As DataRow = _dataset.Tables("Tasks").NewRow
                Dim i_startDate As Date = New Date(Today.Year, Today.Month, Today.Day, 8, 0, 0)
                i_datarow("ID") = 3001
                i_datarow("ParentID") = _projektID
                i_datarow("Bezeichnung") = "inserted Aufgabe"
                i_datarow("Start") = i_startDate.AddHours(6 * 5)
                i_datarow("Ende") = i_startDate.AddHours(6 + 100)
                _dataset.Tables("Tasks").Rows.InsertAt(i_datarow, i_rowIndex)
                Me.RadGanttView1.DataSource = Nothing
                With Me.RadGanttView1.GanttViewElement
                    .TaskDataMember = "Tasks"
                    .ChildMember = "ID"
                    .ParentMember = "ParentID"
                    .TitleMember = "Bezeichnung"
                    .StartMember = "Start"
                    .EndMember = "Ende"
                End With
                Me.RadGanttView1.DataSource = _dataset
            End If
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
