Customize ChartPanAndZoomBehavior for RadCartesianChart

Hi,

I have 3x RadCartesianChart using LinearAxis (Y) and DateTimeContinuousAxis (X).
The zoom & pans shall be synchronized on X, but not Y - right now they are synchronized, but all axes.
The zoom control beside and underneath the axis shall be visible. DragMode shall be Zoom, but only on horizontally - right now I either can zoom only horizontally and only have the horizontal zoom control below OR I can zoom by selection horizontally & vertically and have both zoom controls.

Any path on how to achieve this?

Thanks,
Markus

Issues targetting .NET 4.0/4.0 Client profile

Hi There,

Telerik version 2013.2.611.45
runtime version v4.0.30319

We have a WPF application that is built targeting .net 4.5. Windows server 2003/Windows XP only supports .net runtimes up to version 4, so when I change the target framework to either .net 4.0 or .net 4.0 client profile we get the following error for a bunch of telerik WPF controls.

Error 165 The tag '<TAG>' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'. Line 2 Position 5.

where <TAG> is either RadExpander/RadOutlookBar/RadWindow/RadRichTextBoxRibbonUi which are the controls we are utilizing.

and also :

Error 171 The tag 'RadWindow' does not exist in XML namespace 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation'.

The website says that .net 4.0 is the minimum requirement for Telerik WPF controls, so we are wondering how we go about getting our application to compile when targetting 4.0 / 4.0 client profile. Maybe another installation package built against 4.0 is available?

Any help appreciated.
Thank You,
J

Overriding Implicit Themes

We are using implicit themes and all we want to do is change the transparency of the highlight color (i.e. increase it) for the gridrow when it is selected. Depending on the theme selected the selected highlight color changes and we want to keep that functionality but merely make it more transparent. I understand that we could go change all of the underlying XAML files and recompile the assembly but for such a small change we would rather not do that. Can you suggest any other way of accomplishing this. Thank you

Scrolling problem with GroupDescriptions

Hello,

I have a problem with the RadComboBox control. The telerik version that I use is Q1 2014.

When I group data using ICollectionViewSource, the data are well grouped but some items are not accessible because the scroll go directly to the next group.

How can I solve that problem ?

The code of the Group style is defined below:

01.public FormatBox()

02. {

03. this.IsEditable = false;

04. this.EmptyText = Translator.Translate("Generic_SelectFormat");

05.

06.

07. ScrollViewer.SetCanContentScroll(this, true);

08.

09. DataTemplate itemTemplate = new DataTemplate();

10.

11. FrameworkElementFactory stackPanelFactory = new FrameworkElementFactory(typeof(StackPanel));

12. stackPanelFactory.SetValue(StackPanel.OrientationProperty, System.Windows.Controls.Orientation.Horizontal);

13.

14. FrameworkElementFactory textBlock = new FrameworkElementFactory(typeof(TextBlock));

15. textBlock.SetBinding(TextBlock.TextProperty, new Binding("Name"));

16. stackPanelFactory.AppendChild(textBlock);

17.

18. textBlock = new FrameworkElementFactory(typeof(TextBlock));

19. textBlock.SetValue(TextBlock.TextProperty, " - ");

20. stackPanelFactory.AppendChild(textBlock);

21.

22. textBlock = new FrameworkElementFactory(typeof(TextBlock));

23. textBlock.SetBinding(TextBlock.TextProperty, new Binding("Description"));

24. stackPanelFactory.AppendChild(textBlock);

25.

26. itemTemplate.VisualTree = stackPanelFactory;

27.

28. this.ItemTemplate = itemTemplate;

29.

30.

31. GroupStyle style = new GroupStyle();

32. style.HidesIfEmpty = true;

33.

34. DataTemplate headerTemplate = new DataTemplate();

35.

36. textBlock = new FrameworkElementFactory(typeof(TextBlock));

37. textBlock.SetBinding(TextBlock.TextProperty, new Binding("Name") { Converter = new FormatBoxBooleanToTranslationConverter() });

38. textBlock.SetValue(TextBlock.FontWeightProperty, FontWeights.Bold);

39. textBlock.SetValue(FrameworkElement.MarginProperty, new Thickness(5, 0, 5, 0));

40. textBlock.SetValue(FrameworkElement.VerticalAlignmentProperty, VerticalAlignment.Center);

41. style.HeaderTemplate = headerTemplate;

42.

43. FrameworkElementFactory border = new FrameworkElementFactory(typeof(Border));

44. border.SetValue(Border.BackgroundProperty, new SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 227, 239, 255)));

45. border.SetValue(FrameworkElement.HeightProperty, 20d);

46.

47. border.AppendChild(textBlock);

48.

49. headerTemplate.VisualTree = border;

50.

51. this.GroupStyle.Add(style);

52. }

Thanks in advance, this problem is critical for us.

Localization of Property Grid

I wanting to utilize the PropertyGrid in a application. I have a requirement to support multiple languages. What is the best approach to localize the strings displayed to the user? I am referring the Property Names, and Property Descriptions. I would also like to categorize properties and would like the categories translated.

I have tried an approach I found on CodeProject, but it is designed for WinForms and not WPF. It uses a GlobalPropertyDescriptor which is derived from PropertyDescriptor. This class overrides the Name, DisplayName, and Description properties to retrieve localized strings from string tables. The problem to the approach is the getters for the DisplayName and Description properties are never accessed. The Name property is accessed.

Each class displayed in a PropertyGrid inherits from a common base class that implements an ICustomTypeDescriptor. Most of the what happens here is in the GetProperties functions.

Bottom line is this approach is not working for the WPF version of the PropertyGrid and I am looking for some guidance.
Any assistance is greatly appreciated.
