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

Add functionality to filter items in RadGanttView. 

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

To reproduce: run the sample project and scroll to the end of the view. You will notice that the tasks are not properly aligned. You can increase the GraphicalViewElement.OnePixelTime in order to make the alignment even worse.

Workaround: Adjust the GraphicalViewElement.OnePixelTime in order to obtain the correct alignment.

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. 

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.  

To reproduce:

public Form1()
{
    InitializeComponent();

    DataTable tasks = new DataTable("Tasks");
    tasks.Columns.Add("Id", typeof(int));
    tasks.Columns.Add("ParentId", typeof(int));
    tasks.Columns.Add("Title", typeof(string));
    tasks.Columns.Add("Start", typeof(DateTime));
    tasks.Columns.Add("End", typeof(DateTime));
    tasks.Columns.Add("Progress", typeof(decimal));
    DataTable links = new DataTable("Links");
    links.Columns.Add("StartId", typeof(int));
    links.Columns.Add("EndId", typeof(int));
    links.Columns.Add("LinkType", typeof(int));
    DataSet data = new DataSet();
    data.Tables.Add(tasks);
    data.Tables.Add(links);

    Random rand = new Random();
    int cnt = 3000;
    int cnt2 = 6000;
    for (int i = 1; i < cnt; i++)
    {
        tasks.Rows.Add(i, 0, "Summary task title", DateTime.Now.AddDays(i), DateTime.Now.AddDays(i + 5), 30m);
    }

    for (int i = cnt; i < cnt2; i++)
    {
        tasks.Rows.Add(i, rand.Next(1, cnt), "First child task title", new DateTime(2010, 10, 10), new DateTime(2010, 10, 12), 10);  
    }
    for (int i = 0; i < 2000; i++)
    {
        links.Rows.Add(rand.Next(cnt, cnt2), rand.Next(1, cnt), 1);
    } 
    
    
    this.radGanttView1.GanttViewElement.TaskDataMember = "Tasks";
    this.radGanttView1.GanttViewElement.ChildMember = "Id";
    this.radGanttView1.GanttViewElement.ParentMember = "ParentId";
    this.radGanttView1.GanttViewElement.TitleMember = "Title";
    this.radGanttView1.GanttViewElement.StartMember = "Start"; 
    this.radGanttView1.GanttViewElement.EndMember = "End";
    this.radGanttView1.GanttViewElement.ProgressMember = "Progress";
    this.radGanttView1.GanttViewElement.LinkDataMember = "Links";
    this.radGanttView1.GanttViewElement.LinkStartMember = "StartId";
    this.radGanttView1.GanttViewElement.LinkEndMember = "EndId";
    this.radGanttView1.GanttViewElement.LinkTypeMember = "LinkType";
    this.radGanttView1.GanttViewElement.DataSource = data;
    this.radGanttView1.Columns.Add("Start");
    this.radGanttView1.Columns.Add("End");
}

private void radButton1_Click(object sender, EventArgs e)
{
    this.radGanttView1.PrintPreview();
}

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;

Add a support for image column in RadGanttView

Add possibility to specify the start and end hours when you display hours in the applied time scale. 

Please look at the attached screenshot.

Workaround: you can replace the StackLayoutElement used in the GanttViewTimelineItemBottomStackElement with a DockLayoutPanel for example as follows:

Public Class CustomGanttViewTimelineItemElement
Inherits GanttViewTimelineItemElement
    Public Sub New(data As GanttViewTimelineDataItem, graphicalViewElement As GanttViewGraphicalViewElement)
        MyBase.New(data, graphicalViewElement)

    End Sub
    Dim dock As DockLayoutPanel
    Protected Overrides Sub CreateChildElements()
        MyBase.CreateChildElements()
        dock = New DockLayoutPanel()
        dock.StretchHorizontally = True
        dock.LastChildFill = False
        Me.Children.RemoveAt(Me.Children.Count - 1)
        Me.Children.Add(dock)
    End Sub

    Protected Overrides Sub CalculateItems()
        Me.SuspendLayout()

        Dim cellInfo As GanttTimelineCellsInfo = Me.GraphicalViewElement.TimelineBehavior.GetTimelineCellInfoForItem(Me.Data, Me.GraphicalViewElement.TimelineRange)

        While Me.dock.Children.Count > cellInfo.NumberOfcells
            Me.dock.Children.RemoveAt(0)
        End While

        While Me.dock.Children.Count < cellInfo.NumberOfcells
            Dim element As LightVisualElement = Me.GraphicalViewElement.TimelineBehavior.CreateElement()
            Me.dock.Children.Add(element)
        End While

        Me.TopElement.Text = Me.GraphicalViewElement.TimelineBehavior.GetTimelineTopElementText(Me.Data)

        For i As Integer = 0 To Me.dock.Children.Count - 1
            DirectCast(Me.dock.Children(i), LightVisualElement).Text = Me.GraphicalViewElement.TimelineBehavior.GetTimelineBottomElementText(Me.Data, i + cellInfo.StartIndex)
        Next

        Me.ResumeLayout(True)
    End Sub

    Protected Overrides Function MeasureOverride(availableSize As SizeF) As SizeF
        Dim clientRect As RectangleF = Me.GetClientRectangle(availableSize)
        Dim width As Single = Me.Data.Width - Me.GraphicalViewElement.TimelineContainer.ItemSpacing + availableSize.Width - clientRect.Width

        Me.TopElement.Measure(New SizeF(width, clientRect.Height / 2.0F))
        Me.dock.Measure(New SizeF(width, clientRect.Height / 2.0F))

        Return New SizeF(width, Me.TopElement.DesiredSize.Height + Me.dock.DesiredSize.Height)
    End Function

    Protected Overrides Function ArrangeOverride(finalSize As SizeF) As SizeF
        Dim clientRect As RectangleF = Me.GetClientRectangle(finalSize)

        Dim topRect As New RectangleF(clientRect.X, clientRect.Y, Me.DesiredSize.Width, clientRect.Height / 2.0F)
        Me.TopElement.Arrange(topRect)
        Dim bottomRect As New RectangleF(clientRect.X, topRect.Bottom, Me.DesiredSize.Width, clientRect.Height - topRect.Height)
        Me.dock.Arrange(bottomRect)

        Return clientRect.Size
    End Function
End Class

Public Class CustomGanttViewTimelineElementProvider
Inherits GanttViewTimelineElementProvider

    Public Sub New(owner As GanttViewGraphicalViewElement)
        MyBase.New(owner)

    End Sub
    Public Overrides Function CreateElement(data As GanttViewTimelineDataItem, context As Object) As IVirtualizedElement(Of GanttViewTimelineDataItem)
        Dim element As GanttViewTimelineItemElement = Me.OnItemElementCreating(data)

        Return New CustomGanttViewTimelineItemElement(data, Owner)
    End Function
End Class

To reproduce: please refer to the attached sample project. Try to edit the title for one of the child tasks in the grid and click the 

Workaround:

private void radGanttView1_ItemChanged(object sender, Telerik.WinControls.UI.GanttViewItemChangedEventArgs e)
{
    IEditableObject editebleObejct = e.Item.DataBoundItem as IEditableObject;
    if (editebleObejct != null)
    {
         editebleObejct.EndEdit();
    }
}

How to reproduce:

1. Run the project 
2. Press the radButton1 
3. Edit description of the first line (Line whose Identifier is TestProject1) 
4. Clicking some other line to end the edit causes the ASSERT to come up 

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. 

Hey !

I need to know if you plan the development of a new function :

When you are in the list of your tasks, i want to navigate with the keyboard. 

Im' Here :

And when i navigate in the list with the keyboard, i need to see the last column on the same task :

The focus is good but the horizontal scrollBar is on the same place and we can't the the all value of the cell.

Can we plan the improvment ? Or do you have a clean solution?

If you need more informations,

don't hesitate to contact me

Regards,

Valériane
