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.

grid.ItemContainerGenerator.ContainerFromIndex(index) returns null for the newly added row in code

I was hoping of obtaining the GridViewRow object of the newly added Item (or GridViewRow) by code. The Telerik GridView's ItemSource is bound to Customers ObservableCollection holding Customer object. On the constructor of the window, I populate the Customers collection with 10 items. This shows up fine on the grid. When I click on the button to add 5 more customers, I can see them been added on the grid, however when I try to access the 11th row using grid.ItemContainerGenerator.ContainerFromIndex(10), it returns null.
Is there a different way of obtaining the newly added row's index.

how to make horizontal bar chart with each bar labeled

Hi,

I'd like to make a simple bar chart like the image I've attached. It's really very basic bar chart (not sure Telerik's name for this sort of chart) with a single series. Each of the bars should be labeled with it's value.

Please point me to any examples or snippets that would help me create it. I prefer to do as much of it using MVVM as possible.

Thanks!
