The vertical scrolling seems to become very slow and even unresponsive, when the following conditions are met:

• left and right frozen columns count is 0
• the summary width of all columns is smaller than the width of the RadGridView element

To minimize the issue, you can set the GroupRenderMode property of RadGridView to Nested.

In a scenario where the RadGridView control utilizes the right frozen columns functionality with the RowIndicatorVisibility="Collapsed", CanUserFreezeColumns="False", and RightFrozenColumnsSplitterVisibility="Visible, cells can become missing while scrolling.

The RadGridView control hangs when the frozen columns are enabled and the application is resized. The exact resizing depends on the screen resolution and the exact new size. This was originally recreated on a monitor with 1600x900 resolution 125% DPI and the application was maximized (resized from restored to full screen size). The issue occurs in the Fluent theme. Also, the FluentPalette.Palette.ScrollBarsMode static property should be set to Normal.

To work this around, you can overrider the MeasureOverride method of RadGridView and add the following code:

 

Nested tables with empty cells are not correctly imported. 

Can be reproduced in the demo:

• Open the default document in the radrichtextbox demo
• Activate change tracking (button "Track Changes")
• Make a modification to the document (delete a paragraph)
• Hover your mouse over the delete text: the date in the revision info. has always ":00" for the seconds

In our processes, it is very important to know if a change happened before or after another action. If all the revisions have zero seconds, it's impossible to determine the order of the changes when they happened in the same minute.

This is not a new bug introduce in SP2: it was there in SP1.

Expose API that allows you to add/remove Annotations/IPointerHandler implementations from the PointerHandlersController.

When the RadScheduleView has a recurring appointment with no end date for its recurrence in certain scenarios multiple errors can be try/catch-ed internally, which leads to a degraded performance. One such scenario is when a recurring appointment with no end date starts before the currently displayed time period, but does not have any occurrences before the displayed time period.

As a workaround, an end date can be added to the recurrence rule of recurring appointments.

If a RadTileViewItem hosts several controls (e.g. Buttons, RadioButtons) users should be able to change the focused element using arrow keys.

The cell highlighting doesn't work if the ItemsSourceProvider.ItemsSource is set at runtime, while the drop down is open. The filtering of the items works, but the cell content is not colored.

To work this around, make sure to set the ItemsSource before the drop down gets opened.

The following exception is raised when adding a ColumnGroupDescriptor to the GroupDescriptors property of a RadGridView. This bug is data specific and I've only been able to duplicate it with a large data set but the issue seems like it could be addressed without the actual data, given that the code causing the issue is apparently passing a pixelWidth < 0.

Exception when resizing column with width set to star and min-width set to 0.

Set the properties to the above and resize a column to 0 and then to the original width -> an exception occurs.

 

No license found for Telerik UI for WPF when using Wix installer.

Currently, the RadRichTextBox supports only the MS Pinyin. We could add support for QQ Pinyin.

In your Demo select PivotGrid - OLAP Support

1. sort rows by "Reseller Order Quantity"
2. reopen sorting panel
-> another option will be selected In the sorting options dialog, the selected column in the sorting options appears to be set to a wrong value upon reopening the dialog.

Currently, when pressing the "More Sorting Options..." menu item to customize the sorting, a new SortingEditor dialog is created each time. For its ViewModel property, a new SortingOptionsViewModel instance is created. There isn't an option to persist the customization that the client has performed previously when reopening the dialog, so we could add such an option.

In your demo select PivotGrid - Olap Support

1. add "Exchange Rates: Average Rate" to values
2. sort rows by "Reseller Order Quantity"
-> The grid will be empty

 

If the list is filtered by "Total Reseller Order Quantity != 0", results will show again. Thus, sorting by a column which contains rows without values seems to be faulty.

Currently, RadPdfViewer doesn't allow you to render notes/comments added to the highlight annotations. Add the option to render this and possibly allow editing.

Workaround: Use document processing to fix the document.
