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

When new product features are released it would be useful to show a short introduction for users.  View introjs.com to see a similar solution for web development

I know you added a sample (https://github.com/telerik/xaml-sdk/tree/master/Buttons/ToggleSwitchButton) but please include this in all your Theming dll.

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.

Currently if a column is bound to a field of type DateTimeOffSet it is not displayed using the culture like DateTime is. It would be nice if this is supported in the future

Make the internal static class Telerik.Windows.Controls.WeakEventHandlerManager public.

In Excel it's easy to rotate the contents of a cell. In the Gridview, it's possible to rotate the contents of the header, but the result is a column header that resizes weirdly, and the workaround (at least the one I was provided) is clunky. How about a simple property like <telerik:GridViewDataColumn Header="Name" HeaderRotation="-90" />

With the Windows 10 Anniversary update native controls like TextBox provide this out of the box.

When focusing a Rad Controls like RadDateTimePicker, the watermark is hidden. This behavior could be very problematic when this field is the first of a form. The user will never see the watermark because the focus will be set in this field when entering in the form. It would be nice if the watermark could just be less visible by lowering its opacity. Additionaly, if the user erases the text, it would be nice too if the watermark could be showed at the same visible state than explained above.

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.

Please, provide official Russian Localization for, at least, WPF products. This is the only question, why customers chose other providers than Telerik. For example, I like Telerik WPF controls more, but me head at work bought other WPF-vendor because they provided official Russian Localization. Thanks.

Allow to define ChartGrid for axis, not for chart.
Every Axis can draw our grid lines.
Chart.Grid can be a wrapper for Chart.Horizontal and Chart.Vertical axes.

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.

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! :)

Deliver an icon library which can be easily used in the user's application.

In addition to the great nuget packages, could we also get Nuget packages with symbols baked in?

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