Currently, the appointments in the same group in TimelineViewDefinition will be drawn on multiple lines if their date ranges overlap. Internally, the group height is split into "rows" for each overlapping that happens and then each appointment is rendered on the corresponding row.
Add a mechanism to control the number of rows and the row position of each appointments in the same group.

Currently, the GenerateExport method provides a PivotExportModel instance where the Cells collection is populated with the formatted value of the cells.
We could add an option to allow the copying of the raw data instead.

RichTextBox
Type:
Feature Request
FormatException is thrown during the import of a table coming from a docx document when the application culture is "sv-SE". This happens when the column width in the document is a floating point number (ex: 120.65). The Swedish culture uses "," as decimal separator and " " as the number group separator, which makes any invariant decimal value (like 120.65) invalid during standard parsing (ex: float.Parse("120.65")).
Stacktrace:
FormatException: The input string '4514.5' was not in the correct format. at System.Single.Parse(String s) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.ImportTableGrid(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style style) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.Import(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildTable(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildBody() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildDocument() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.Import()Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentAndRelationsFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.Import() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider.Import(System.IO.Stream input)
To work this around, switch to InvariantCulture during the import and return the original culture after that.
var cultureCache = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture;
var provider= new DocxFormatProvider();
rtb.Document = provider.Import(stream);
Thread.CurrentThread.CurrentCulture = cultureCache;
Thread.CurrentThread.CurrentUICulture = cultureCache;

Feature Request
When developing live (localization/resource) display language switching for SL5, the LocalizationManager should allow to update all localization strings applied through the ResourceManager. In SL5 it's not possible to listen to an attached dependency property for all dependency objects. Therefore it would help to have a way to know when the attached ResourceKey dependency property changes (and on which DependencyObject) in the LocalizationManager.

Currently, the only customization that can be performed is using HyperlinkToolTipFormatString property of RadRichTextBox, which sets the format for all hyperlinks in the document of the control. It would be nice if it were possible to be able to set different tooltips.

DateTimePicker

Currently, on lost focus of RadDateTimePicker, the input text is validated and if it is not in the proper date-time format the text is cleared. This forces the user to write the full date-time value again when a mistake is made. Add a mechanism to allow invalid date-time texts without automatically clearing the text input field.
