FileDialog with ExpandToCurrentDirectory set to false and a network location set as initial directory.
On Load, Breadcrumb shows only Network node but it should actually show the full path to the requested folder. Then this leads to inability to navigate upward with buttons next to breadcrumb bar.

Steps to Create Problem using  EditableTextBoxTemplate_WPF sample project provided by Telerik:(modified project is zipped and attached just in case)

- Edit Example.xaml to add "AllowMultipleSelection="True":

            <telerik:RadComboBox  IsEditable="True" ItemsSource="{Binding Companies}" SelectAllTextEvent="None" FontFamily="Calibri" FontSize="14"
                                  DisplayMemberPath="Name" EditableTemplate="{StaticResource EditableComboBox}"
                                  Width="220" Height="50" DropDownWidth="*" x:Name="comboBox" Margin="5 10" AllowMultipleSelection="True"/>


1) Run project 

2) Click drop down button to see list in the drop down

3) Type "Global" (at this point it should autocomplete "Global Corporation")

4) Without clicking on anything or Press space bar to continue typing (type space character)

5) Typed text will disappear leaving only space character behind - At this point, nothing is selected.


This does NOT happen if typed text before space does NOT match with any item from the list. 

This does NOT happen if AllowMultipleSelection set to false

This does NOT happen if dropdown is NOT open while typing.

Release LIB 2021.2.802 (2 Aug 2021)

When placing controls in the CellTemplate/CellEditTemplate in the RadMultiColumnComboBox`s dropdown`s GridView some do not receive/accept the mouse input correctly.

In the newest version (2021.2.615) the dropdown of a RadDatePicker does not open. A RadButton works fine and a RadComboBox open and can select an item via mouse click.

In a previous version (2021.1.325) the RadComboBox also does not work, this seems to be fixed already.


I have attached a sample project demonstrating the behavio:

1) start the project

2) open the dropdown of the RadMultiColumnComboBox

3) click on the RadDatePicker`s calender icon button. => the calender view does not open

The very same DataTemplate is applied obove the RadMultiColumnComboBox to illustrate the proper behavior in contrast.


The behavior is visually demonstrated in the .gif (1.gif and 2.gif) I have attached.

Bug can be reproduced in PivotGrid => Olap Support in demo application.
Under all main categories in the designer, there is a folder called "Sets" that has the exact same content.

It either is mistakingly placed under each "category" or should be something that sits on top of them in a more global fashion.

Bug can be observed in Pivot Grid => Olap Sorting example in  the most recent demo.

Sadly i do not know what this menu is called in english (and the demo cannot change language) so here is a screenshot

Set it to 'Equal' 'Lisa Cai'

If you hit ok and refresh, all values are gone.
Weirdly if you change it to not equal, you still get zero results

The sort order of the aggregated values is wrong when the sorted field contains null values. To reproduce this the null values should be allowed by setting the IgnoreNullValues property of the associated PropertyAggregateDescription object to False.

A NullReferenceException is thrown when a new picture is inserted in a document with enabled tracked changes. Sometimes it might take two or three images to be inserted for the exception to occur once the document is open. The original document should contain image >> text >> image >> text.
