It would be nice if the Telerik UI for WPF VSExtensions detected usage of UI for WPF in class libraries (e.g. a WPF UserControl Library)..

This would allow the Upgrade Wizard / configure Project wizards can also work on the class libraries, too.

This is a MVVM helper that could be used to decrease the coupling between the view models.

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

Hi support,
I've mixed RibbonWindow Sample and Prism with ReagionManager and RadDocking in this sample. When I try to dock a derived RadPane (e.g. OutputView or others) in center of the compass menu the derived RadPane Header is not shown as a tab in the split container. Only pure RadPane instances  (c.f. "_regionManager.RegisterViewWithRegion("DockingRegion", typeof(RadPane)); " in FileServicesModule class will dock in correct manner. 

Please can you add xlsm file support to RadSpreadProcessing.

Introduce support for AutoCad files in a fixed document viewer.

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

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

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 

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 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.

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

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.

One requires to create QueryableCollectionView on the UI thread.
Now there's going to be a .Count() call on the IQueryable passed into the constructor,
which will block the UI thread until it returns.
There might be various reasons why there is delay (unable to connect to DB,slow query, using a REST queryable provider, etc).

It would be nice if we could pass in the count ourselves.

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" />
