When you apply an average aggregate function (for example via the RadPivotFieldList control) a VerificationException is thrown. The exception message is: "Operation could destabilize the runtime."

Using RadOpenFileDialog reports a lot of binding errors. #26 seems to happen all the time, whereas #40 is related to the length of the initial directory.

The dialog is working, but those errors are really disturbing. The more false binding errors we get, the higher the possibility is that we miss real errors. Suppressing them by setting the error level to Critical is not a solution, as it will suppress real errors as well.

If you forbid the app access to the camera via the Windows settings a System.Exception is thrown when you start the RadWebCam control. The exception message is 'MFCreateDeviceSource failed: E_ACCESSDENIED'

EnableAsynchronousTextInsertion is not respected in a custom caret and any text input is now process asynchronously. 

For example, the default namespace prefix for BlipElement is r: if the namespace prefix is different an exception will occur.

If you try to show a window, and right afterwards call RadWindow.Alert() or any other prompt dialog, the main window automatically closes.

To work this around show the prompt in the Loaded event handler of the RadWindow.

When the RecurrenceFrequency is set to Year. The GetOccurrences() method of the RecurrencePattern does not respect the Interval property.

When opening a document which contains date fields, RadRichTextBox doesn't update their values.
Workaround: Invoke UpdateAllFields() or UpdateField().

The items inside the Tree Navigation Pane are not sorted in the same way as the native MS dialog. In our OpenFolderDialog when there is a file or folder name which starts with underscore "_" the file/folder is placed at the bottom of the tree navigation view. Looking at the tree from the MS dialog it is placed at the top.

In the Main Pane, the items are sorted correctly.

TabbedWindow with 2 tabs, each tab has Frame which almost fully covers the content.

Step 1) Drag drop a tab to the visible content. 2) Then bring it back to the first window with drag drop. Step 1 is now impossible - no window is created after drag out of tab strip and drop onto the content.

Possible workaround: Set AllowDrop to True to the control (in this case frame) in the content of the RadTabItems.

When the new value is selected from the GridViewMultiColumnComboBoxColumn, the event arguments in the CellEditEnded event does not contain the new value. 

The scale factor is not imported from documents with no information about the selection state.

 

Loading document containing link with no destination leads to ArgumentNullException in PdfElementToFixedElementTranslator.CreateDestination method.

An InvalidOperationException is thrown with the following message: "Cyclic reference found while evaluating the ThemeStyle property on element ..."

If the document contains a style that is based on a style with a duplicate name, RadDocument detects it as a cycle in style inheritance.
