If series datasource is ordered, asc or desc, all actions that serch a subset of data can be ultra speed. At the moment working with large datasets and zoom/trackbals cause occasional chart freeze.

Possible solution:

1) Declarative: The developer declare that the dataset is ordered asc/desc.
2) Automatic: On points add/remove chart verifies if data is ordered.
3) Programming: Chart allow to override serch in database functions.

My suggestion is 1) or/and 3)

Add a way to aggregate TimeSpan values and apply different string formats. 

Hi,

in your UI for WinForms Suite is a control called CheckedDropDownList. This control is just awesome so why it doesn't exists as WPF Version? Yesterday I was in need to create a close one with a AutoCompleteBox and a Button for drop down the list. But this isn't exactly what I need and it feels a bit...unperfect.

So please create this great control for WPF! :)

I have a Winforms application (Very Large so there is no changing it any time soon) that launches a WPF window with a .show(). In this WPF window I have radDocking. In one of the RadPanes I have a WPF TextBox. As long as the RadPane is docked the TextBox will receive text. However, if I undock, the TextBox will no longer receive text input.
I do not see this issue, however, when launching the WPF window in my WPF test app.

Please let me know if there is some kind of work around for this issue.

I have attached a test app that I have created which will demonstrate the issue. You will have to point the "TextBoxInRadPanel"  to your Telerik DLLs, they were too big to attach.

Repro Steps:
1. Launch the HostApp
2. Click the "Press Me" button
3. Type into the TextBox in the docked "UC Test" RadPane - input is received
3. Undock the "UC Test" RadPane
4. Attempt to type into the TextBox area - no text input will be received.

When MainView.xaml is opened, the designer throws NullReferenceException because the SelectedOutlookSection is not initialized.

Workaround: If SelectedOutlookSection is null, then initialize it to point to the first item from the collection of outlook sections:

public OutlookSection SelectedOutlookSection
{
    get
    {
        if (this._selectedOutlookSection == null)
        {
            this._selectedOutlookSection = this.OutlookSections.FirstOrDefault();
        }

        return this._selectedOutlookSection;
    }
  ...
}

The fix is available in R1 2017 SP1.

Add a property to the RadWindow, to enable a behavior, so that when the user attempts to focus on the parent window (while the modal is open), the modal window will flash.

You can see this behavior in other Windows applications that show modal dialogs.

We use 'xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"' in our application.
The problem is that DrapAndDrop does not work anymore, no Events are fired.

Since our last release we didn't change anything at our UI and as I tried a few days ago to drag something in the application and nothing happened.

Did something change with the previous mentioned reference?
What are possible solutions?

Thank you in advance 

Improve the support for async operations. Currently, if the db data context is shared between the collection and another consumer, issues could occur.

The event args for the RadDocking.ActivePaneChanged are named "ActivePangeChangedEventArgs" which I'm assuming is a typo for "ActivePaneChangedEventArgs".

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.

We provide such properties in our Green theme and they make customizing the read only states of all controls easier.
Currently the read only state looks like disabled and there is no easy way to change it. 

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.

css style like the background color for the pinned rows can be different from the rows in the grid to differentiate the rows

Hi,

I have implemented a WPF application that displays various pages.

I have the following code that is executed on one of my pages after a user logs in. This same code is executed when the user returns to the page:

If myUser.IsInRole("Master") Or myUser.IsInRole("Administrator") Then
            myRadGridView.SelectionMode = SelectionMode.Multiple
Else
           myRadGridView.SelectionMode = SelectionMode.Single
End If

After logging in the myRadGridView grid behaves as if it is SelectionMode.Single even though my user is in the role "Master" and the code branch above is executed to set the myRadGridView grid into SelectionMode.Multiple.

That being said, if I leave the page and come back to it, the same code is executed and the myRadGridView grid finally behaves as it should be in SelectionMode.Multiple.

How do I fix get this to work?

Thank you.

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.

The fix will be available in the R1 2018 SP2 Release.
