We have a WCF service that continuously polls a database for new/updated items and sends them to WPF clients.  The client will process the update, decide what to do and then add/update an item that is displayed in a RadGridView.  We use an IEditableCollectionView on top of an ICollectionView.  Exception detail is below.

App just crashed while sitting idle on Zarate,

No mention of MSCORLIB so I think its a different error.

In case table cell doesn't have background directly applied it should inherit the background of its parent table.

Video (wmv) and Audio (wav) files aren't properly compressed. The zip file that the library creates is larger than the original media file.

When operation stream is created on top of the stream which doesn't support seeking the NullReferenceException is thrown from the constructor. There are other things which makes impossible using of the ZIP library on the stream which doesn't support seeking. We should fix these things.

When setting IsSynchronizedWithCurrentItem to true, the RadListBox behaves differently from the standard ListBox; changing the selection in the RadListBox does not update the current item of the underlying ICollectionView.

It seems that on some devices a touch with the Stylus doesn't fire the WPF native Touch events. Only the Stylus events will be fired. Because the TouchManager internally works only with the WPF Touch events, the manager's events are not fired.

Affects RadDateTimePicker control of TelerikWPFControls version 2015.1.1

When the user is typing in a specific date and time, the RadDateTimePicker control's text-to-date parsing doesn't accept an uppercase 'A' at the start of what it expects to be the month's name and automatically errors (displays a tooltip showing 'Error') as soon as an 'A' is input. This prevents the user from entering dates and times more specific than the clickable selection for the months of 'April' and 'August'. However, replacing the 'A' with a lowercase 'a' allows the user to proceed with entering more specific dates and times as normal without the 'Error' tooltip showing. 

E.g.: 
1) the user selects 03 April 2018 17:00:00 from the control's clickable selection of date and times;

2) they then try to type more specific minutes and seconds, e.g. 03 April 2018 17:45:23, but this is not accepted by the control and it displays the 'Error' tooltip;

3) workaround - the user changes 'A' of 'April' to a lowercase 'a', as in 'april'. Now the 'Error' tooltip goes away and the user is able to enter and save the more specific date time of 03 april 2018 17:45:23.

This bug only came to light once the control was live in production (released in January) and prevented our users from entering the specific trade date times necessary for regulatory purposes.

Can you tell me if this bug has been fixed in later versions of the control?

Thanks and regards,

Robert Fiteni

maybe there are some ways to appear the  mouse point offset grow in steps when move the float window in raddocking by mouse drag.but I found when move the float window's header pass the document's tab,don't docking,then release mouse,and then move the float window again back and forth or up and down,the  mouse point offset grow in steps, at last the mouse's point leave the float window's header with hold the window's drag state.

When I scroll around in RadVirtualGrid, I get empty cells in some places.

Details:
- I set InitialRowCount=21 and InitialColumnCount =17.
- The window that contains the VirtualGrid is rather small, so that the horizontal and vertical scrollbars are visible.
- I can always reproduce this issue, if I scroll completely to the right, then completely to the bottom and then half-way to the left.
- I found out that the CellValueNeeded event is never called with the indexes for these cells.
- I'm using version 2017.2.614.45 (NoXaml) of UI for WPF.
- I attached a screenshot showing the empty cells and my example project.

A project with problems in RadTreeListView in the attachment.

Description of the project:

The element RadTreeListView have the name ObjectsTree.  As the ItemsSource of ObjectsTree set the child elements of ObjectsTreeViewModel. ObjectsTreeViewModel contains child elements of type ParentNode. The elements of ParentNode have childrens with type ChildNode. (In the project are used 3 ParentNode elements with 3 childNodes at everyone).

ChildNode elements that have the property ShowNode  equals false should not be displayed. To do this, used the FilterDescriptor. The property IsConnected of ChildNode elements sets the ShowNode property (ShowNode = IsConnected).

The button "Node to offline" is used to reset a property IsConnected to the selected ParentNode element and to all of his children.
The button "All Nodes to online" is used to set a property IsConnected to the all ParentNode elements and to all of their children.
The button "Check Memory Leak" is used update ObjectTree 10000 times.
If you check radiobutton "With Rebind" update using Rebind() command
If you check radiobutton "With clearing filter" update using command sequence : FilterDescriptors.Clear -> FilterDescriptors.Add.

Description of the problem:
1)	When updating the tree using the sequence of commands FilterDescriptors.Clear (); FilterDescriptors.Add (...):
The visual element displays the elements of tree correctly, but there is a memory leak.

2)	When updating with Rebind ():
Memory leaks are not present, but we may see following bug:
Select ParentNode.
Press the "Node to offline" button      -> The child elements are hidden, but a triangle for expanding the list elements is visible.
When you click on this triangle            -> it disappears
Press the button "All Nodes to online" ->the children and the triangle do not appear.
