Please use the following code snippet:

 

    public partial class Form1 : Form
    {
        public class VM
        {
            public string Text
            {
                get; set;

            {
                get; set;
            }
        }

        public Form1()
        {
            InitializeComponent();

            var ViewModel = new VM[]
            {
                new VM()
                {
                    Text = "CrashTest",
                    Start = new DateTime(2021, 11, 3, 10, 0, 0),
                    End = new DateTime( 2021, 11, 3, 23, 0, 0 )  //crash
                    //End = new DateTime( 2021, 11, 3, 22, 0, 0 )  //No crash
                },
            };

            radGanttView1.GanttViewElement.GraphicalViewElement.OnePixelTime = new TimeSpan( 0, 1, 0 );
            radGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = ViewModel.Min( T => T.Start );
            radGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = ViewModel.Max( T => T.End );
            radGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = TimeRange.Day;

            radGanttView1.GanttViewElement.ChildMember = "Text";
            radGanttView1.GanttViewElement.TitleMember = "Text";
            radGanttView1.GanttViewElement.StartMember = "Start";
            radGanttView1.GanttViewElement.EndMember = "End";

            radGanttView1.DataSource = ViewModel;
        }
    }

Currently, the possible solution that I can suggest is to increase the view's end with 1 hour:

  radGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = ViewModel.Max( T => T.End.AddHours(1));

Please refer to the attached gif file.

Steps :

1- Open a cell in edit mode (type Date).

2- Move the mouse outside this cell (without click)

3- Click on the arrow buton to open the calendar without focusing on the date cell (by the right).

5- The calendar does not open. (If we move the mouse over the date cell first, the calendar open fine)

Run the attached sample project and select the second page. You will notice that the tasks are missing. This used to work in R2 2019 (version 2019.2.508).

Workaround: Initialize the RadGanttView.BindingContext before adding it to the page:

        Dim Gantt As New RadGanttView
        Gantt.Dock = DockStyle.Fill
        Gantt.BindingContext = New BindingContext()

Please use the following code snippet to setup the Gantt view:

Sub New()

                 


        InitializeComponent()

        Dim dt As New DataTable
        dt.Columns.Add("ID", GetType(Integer))
        dt.Columns.Add("Group_ID", GetType(Integer))
        dt.Columns.Add("Title", GetType(String))
        dt.Columns.Add("Start", GetType(DateTime))
        dt.Columns.Add("End", GetType(DateTime))

        dt.Rows.Add(-999, 0, "Root", New DateTime(2019, 8, 21), New DateTime(2019, 8, 30))
        dt.Rows.Add(6, -999, "Item 1", New DateTime(2019, 8, 21), New DateTime(2019, 8, 23))
        dt.Rows.Add(7, -999, "Item 2", New DateTime(2019, 8, 26), New DateTime(2019, 8, 30))
        dt.Rows.Add(1000, 6, "Sub1.1", New DateTime(2019, 8, 21), New DateTime(2019, 8, 22))
        dt.Rows.Add(1001, 6, "Sub1.2", New DateTime(2019, 8, 22), New DateTime(2019, 8, 23))
        dt.Rows.Add(1002, 6, "Sub1.3", New DateTime(2019, 8, 23), New DateTime(2019, 8, 23))
        dt.Rows.Add(1003, 7, "Sub2.1", New DateTime(2019, 8, 26), New DateTime(2019, 8, 29))



        Me.RadGanttView1.DataSource = dt
        Me.RadGanttView1.ChildMember = "ID"
        Me.RadGanttView1.ParentMember = "Group_ID"
        Me.RadGanttView1.TitleMember = "Title"

        Me.RadGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = New DateTime(2019, 8, 20)
    End Sub 

However, if you switch the order of adding the rows, not all items will be visible in RadGanttView:

dt.Rows.Add(1000, 6, "Sub1.1", New DateTime(2019, 8, 21), New DateTime(2019, 8, 22))

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:

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

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

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.

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.

Hi,

why is the datatype of the ChildMember/ParentMember item limited to Int32? This is a problem when displaying tasks or events from tables with string or UUID idents. It would be a more flexible control if the type could be any type. Should not be a big deal to change this or is it?

Thank you und kind regards

Karsten

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

Hey,

 

We have a problem with the GanttViewTimeLineContainer as you see in the screeshot  : gantt_print2.png

When we are in TimeLineRange = TimeRange.Year and we print the gantt, we have a problem with the appearence of GanttViewTimeLineContainer, we can see the first line with the year (it's ok) but after, the second line we can see a reperition of all month : jfmamjjasond jfmamjjasond jfmamjjasond jfmamjjasond etc etc etc

Can we change the appearence ? Do you have an explanation for this visualization ? 

 

Thank you,

Regards,

Valériane E.

When you edit a link, e.g. change its end item, there is no appropriate event to handle this situation. The Links.CollectionChanged event is not fired. It would be nice to have a LinkChanged event which will be fired when a link is modified similar to the ItemChanged event for the tasks.

Workaround:
            foreach (GanttViewLinkDataItem link in this.radGanttView1.Links)
            {
                link.PropertyChanged += link_PropertyChanged;
            }

        private void link_PropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            if (e.PropertyName == "EndItem")
            {
            }
            
        }

To reproduce: please run the sample project and follow the steps illustrated in the attached gif file. This shows how I’m attempting to add children to a root task. Upon adding a child task I am unable to scroll down to see the rest of the pre-existent root tasks until I first collapse and expand any visible root or child task.

Workaround:

        public RadForm2()
        {
            InitializeComponent();

            this.radGanttView1.ItemAdded += radGanttView1_ItemAdded;  
        }
       
        private void radGanttView1_ItemAdded(object sender, Telerik.WinControls.UI.GanttViewItemAddedEventArgs e)
        {
            item = e.Item;
        }

        GanttViewDataItem item;
        
        private void radButton1_Click(object sender, EventArgs e)
        {
            this.radGanttView1.GanttViewElement.InvalidateMeasure(true);
            this.radGanttView1.GanttViewElement.UpdateLayout();

            this.radGanttView1.GanttViewElement.GraphicalViewElement.Scroller.ScrollToItem(item);
        }
