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,

check the attach file,the gridview's droplist extend the screen area,
my screen is 2560x1440/175% DPI/14 inch/windows 10

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.

Fix available in R2 2018 SP1 version.

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.

Setting the TextWrapping to Wrap or WrapWithOverflow will not allow the WatermarkContent to be wrapped.

Reason for decline: 

Instead of setting the content inline, we recommend setting it as follows: 

<telerik:RadWatermarkTextBox Width="100">
	<telerik:RadWatermarkTextBox.WatermarkContent>
		<TextBlock TextWrapping="Wrap" Text="Watermark Content Watermark Content Watermark Content Watermark Content" />
	</telerik:RadWatermarkTextBox.WatermarkContent>
</telerik:RadWatermarkTextBox>

More information can be found in our help about using the WatermarkContent and WatermarkTemplate properties: https://docs.telerik.com/devtools/wpf/controls/radwatermarktextbox/features#using-the-watermarkcontent-property
Please let us know if this is not applicable in the scenario of your application.

Similar to File Explorer in Windows 10, it would be helpful to have a Quick Access section in the left navigation pane with the ability to pin frequently used items.

File explorer with the drag and drop upload and just a richer interface

A component to easily chat with visitors on a website.  It's becoming popular to be able to interact and offer support that way.  Maybe based on the Windows Live Components or something along those lines.

When both horizontal and vertical ScrollBars are visible in Fluent theme, the "BottomHandle" RepeatButton cannot be pressed as it is overlapped by the horizontal ScrollBar on MouseOver. 

Default behavior will be changed and the scrollbars will be reordered in the ScrollViewer ControlTemplate so on MouseOver the current ScrollBar will have higher Canvas.ZIndex. 

look the attach file.

Controls are not visible in design-time when the build platform is x64.

Would it be possible to add a new theme that accurately tracks the Google Material Design guidelines?  (http://www.google.com/design/spec/material-design/introduction.html).

looking the attach file,when resize the second gridview's column moving back and forth when at first run the sample,the after columns flicker and the width grow and lessen.and when resize the third column,the 'unit price' column will become the min width.
but when test the microsoft's datagrid,it is good,the any other column width's change is gentle.

User can set AutoCalculateBounds to True by the following way:

 public class CustomClusterGenerator : DefaultClusterGenerator
    {
        public override ClusterData CreateCluster(Location center, object item)
        {
            var clusterData = base.CreateCluster(center, item);
            clusterData.AutoCalculateBounds = true;
            return clusterData;
        }
    }

  this.VisualizationLayer1.ClusterGenerator = new CustomClusterGenerator();

When clustering 4 points:

ObservableCollection<DataItem> items = new ObservableCollection<DataItem>()
            {
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(20, 30) },
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(20, 34) },

                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(22, 32) },
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(18, 32) },
            };

            this.VisualizationLayer1.ItemsSource = items;

EXPECTED:  ClusterData's Bounds must  be:

WEST: 30 and EAST: 34.

Actual Values are 30 and 30 (29.9999 and 30).
