I have a diagram with about 45 custom image objects contained within it. When I export the diagram to a png using RadDiagram.Export("PNG") there are 3 images that are not rendered in the image.

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.

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" />

The problem is happening with Rad Docking in X1 Yoga Thinkpad laptop. The problem is so that when launching the pane in Raddocking then the pane opens up outside the window. This is happening even if the window is not near to the border of the screen. Video and the same project attached.

For example, when DateTimePicker.FlowDirection=RightToLeft, the CalendarIcon is inverted [Windwos8, Greeen, Office2013 etc. themes].

InvalidProjectFileException is thrown when ApiAnalyzer cannot find the file Microsoft.VisualStudio.ServiceModel.targets referenced from a WPF project.

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.

The issue is also observable in the Outlook project template as well - in the NewEmailWindow. As a workaround, the ScreenTip can be removed by deleting the following code:
telerik:ScreenTip.Icon="{telerik:IconResource IconRelativePath=FontDialog.png,IconSources={StaticResource IconSources}}"  

Fix available in R3 2018 SP1 release.

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.

This blends the text with the background and only a black rectangle is displayed. See the attached image.

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.
