[Solved] Bing imagery sets

I'm using an older version. Do the new versions have built-in support for the new (?) imagerySet values? If not, how would I add them? I've used my own or inherited versions of OSM classes, but the Bing classes are more complex and have more levels of inheritance. Below is the documentation for the static map, but I don't know if this applies to Tiles, too.

https://msdn.microsoft.com/en-us/library/ff701724.aspx

Aerial – Aerial imagery.
AerialWithLabels –Aerial imagery with a road overlay.
CanvasDark - A dark version of the road maps.
CanvasLight - A lighter version of the road maps which also has some of the details such as hill shading disabled.
CanvasGray - A grayscale version of the road maps.
Road – Roads without additional imagery.

But if any property of item will be changed, the group contains this item will be expanded automatically. I want this group to be expanded regardless of the property changes. Is it bug or feature of RadGridView? Tell me, please, how I can fix it?

Export to xlsx format issues

I am using GridView's export functionality of 2016.1.217.45 version, see below the code snippet.

string extension = "xls";

SaveFileDialog dialog = new SaveFileDialog()

{

DefaultExt = extension,

Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "Excel"),

FilterIndex = 1

};

if (dialog.ShowDialog() == true)

{

using (Stream stream = dialog.OpenFile())

{

m_oGridView.Export(stream,

new GridViewExportOptions()

{

Format = ExportFormat.Xlsx,

ShowColumnHeaders = true,

ShowColumnFooters = false,

ShowGroupFooters = false,

});

}

Following are the issues observed, please provide solutions or workarounds:

The first row in the grid is not getting exported as second row in excel, instead it is appearing in the first row of excel after the row headers. See the snapshots - "GridUISnapshot.JPG" and "ExcelSnapshot.JPG".
If the users specifies the extension of the file as ".xlsx", it is getting exported but not able to open in excel 2016 version, the error message is shown in the snapshot - "XlsxExtensionOpenError.JPG". Since in File save dialog, user can specify .xlsx extension as well. In code we are specifying the format to be exported is xlsx, but still it is not compatible.

Thanks,

Viksit

Search Panel and Combo Box Column

I'm playing around with the developer example projects for the gridview, specifically the "ComboboxColumnItemsSourceBinding", and I enabled the Search Panel on the Gridview where FilterMemberPath is set, but noticed it doesn't search inside the ComboBox Column. If I type for "Webber" in the Search Panel it comes up with nothing.....but the filter control for that column will work.

Is there something I am missing in the demo that I need to add to get this functionality working? Or do I need to go as far as making my own predicate and use FilterDescriptor<T>?

RadMaskedNumericInput Problem

1) The below numeric input is always displaying 0 on screen load. I don't want to show anything. Latitude is defined as Decimal? is ViewModel.

2) I want this to allow only values between 32 and 38 upto 5 decimal digits.

How can I do this ?

SnappingEngine and Bounds.Rect.IntersectWith

Hi to all,

I would avoid ovelap between RadDiagramShapes (all rectangle items).

When I set IsSnapToGridEnabled="False" IsSnapToItemsEnabled="true" and move RadDiagramShapes, SnappingEngine uses snap on myshape aligned to other ractangle.

If I try to user MyMovedShaped.Bounds.Rect.IntersectWith(OtherRectangleShape) returns me ever True.

I'm using this code:

01.private void topRadDiagram_Drag(object sender, DragRoutedEventArgs e)

02.{

03. var diagram = (RadDiagram)sender;

04.

05. foreach (var item in e.Items)

06. {

07. var currentItem = (RadDiagramShape)item;

08.

09. var shapeItem = (GruppoPianoDiCarico)currentItem.Tag;

10.

11. foreach (RadDiagramShape otherItems in diagram.Items)

12. {

13. if (otherItems.Tag.GetType() == typeof(GruppoPianoDiCarico))

14. {

15. var shapeOther = (GruppoPianoDiCarico)otherItems.Tag;

16.

17. if (shapeItem != shapeOther)

18. {

19. if (currentItem.Bounds.IntersectsWith(otherItems.Bounds))

20. {

21. //Da ripristinare le coordinate originarie

22. currentItem.Position = new Point(currentItem.Position.X - (e.MousePosition.X - e.StartMousePosition.X),

23. currentItem.Position.Y - (e.MousePosition.Y - e.StartMousePosition.Y));

24. }

25. }

26. }

27. }

28. }

29.}

[Solved] Connections don't get removed when node is deleted

I have a MVVM setup with GraphSource etc. as described in this example: http://docs.telerik.com/devtools/wpf/controls/raddiagram/populating-with-data/data-databinding

When I delete a node, the connecting edges are not getting deleted. I see this working in various other examples, but for me, the edges remain on the diagram. I found an old post from 2013 about this functionality not working, but I expect that in 2017, that bug has been fixed: http://www.telerik.com/forums/remove-connections-when-removing-node

Before I post more (code) details: Is the behavior expected to work? If yes, what's a good way to debug why edges are not getting correctly deleted for me?

Drag and Drop with RadDiagramShape.Tag valued

I'm trying to drag&drop from my radlistbox that has ItemSource with my Collection (by MVVM)

I valued RadDiagramShape.Tag property with my object, I would to send this one also.

But into ItemsChanged event I found Tag = null.

How can I do this?

DragDropManager.AddDragInitializeHandler(MacchineDaCaricareRadListBox, OnDragInitialize);

private void OnDragInitialize(object sender, DragInitializeEventArgs args)

{

args.AllowedEffects = DragDropEffects.All;

//RadDiagramShape draggedShape = (args.OriginalSource as ListBoxItem).Content as RadDiagramShape;

GruppoPianoDiCarico pallet = (args.OriginalSource as RadListBox).SelectedValue as GruppoPianoDiCarico;

RadDiagramShape macchina = new RadDiagramShape()

{

Width = pallet.Lunghezza / SCALE,

Height = pallet.Larghezza / SCALE,

Content = $"[{pallet.NumeroRiga}] {pallet.Description.ToUpper()}",

Tag = pallet

};

macchina.Geometry = ShapeFactory.GetShapeGeometry(CommonShapeType.RectangleShape);

macchina.Background = IMBALLO;

macchina.Foreground = IMBALLO_TITLE;

macchina.FontWeight = FontWeights.Bold;

macchina.Stroke = Brushes.Black;

macchina.StrokeThickness = 1;

macchina.StrokeDashArray = new DoubleCollection(new Double[] { 5, 1 });

macchina.FontSize = 20;

List<RadDiagramShape> shapes = new List<RadDiagramShape>();

shapes.Add(macchina);

SerializationInfo serializaedInfo = SerializationService.Default.SerializeItems(shapes);

args.Data = serializaedInfo;

}

private void topRadDiagram_ItemsChanged(object sender, DiagramItemsChangedEventArgs e) { [...] if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add) { foreach (var item in e.NewItems) { var currenItem = (RadDiagramShape)item; //it founds Tag = null!!!! if (currenItem.Tag.GetType() == typeof(GruppoPianoDiCarico)) { var macchina = (GruppoPianoDiCarico)currenItem.Tag; vm.MacchineDaCaricare.Remove(macchina); vm.MacchineCaricate.Add(macchina); } } } }
