Environment: VS Community 2019 (16.0.3), with .NET Framework 4.8 (release version, run-time and developer pack installed), Windows 10 Pro October 2018

Telerik UI version: latest (2019.1.220.45)

When VS2019 opened, Telerik UI for WPF should have been found under the "Extension" menu --> Telerik --> Telerik UI for WPF. However, there is only "Telerik UI for WinForms" under "Telerik" now. There is neither "Telerik scenario" in the "Add New Item" window so no RadForms can be created. Manually replacing <Window> in XAML to <telerik:RadWindow> does change the appearance of the window in the designer, but the properties in the Property window does not change accordingly to RadForms but still WPF standard Form ones. Toolboxes shows current lists of Telerik UI for WPF controls and they can be correctly created (at least RadButton). "Repair" in the Progress Control Panel doesn't fix this problem.

Thanks!

The following xaml code

            <telerik:RadComboBox Margin="5"
                                 ItemsSource="{Binding Path=AvailableServices}"
                                 IsEditable="True" 
                                 Text="{Binding Path=Service, Mode=TwoWay}"/>

            <ComboBox Margin="5"
                                 ItemsSource="{Binding Path=AvailableServices}"
                                 IsEditable="True" 
                                 Text="{Binding Path=Service, Mode=TwoWay}"/>

with this view model

public class ViewModel
    {
        public ObservableCollection<string> AvailableServices { get; set; } = new ObservableCollection<string> { "UPS Standard", "UPS Express Saver", "UPS Express 12:00", "UPS Express" };

        public string Service { get; set; } = "UPS Express";
    }

produces the attached output. 

The standard WPF ComboBox is set to "UPS Express" as expected while the RadComboBox shows "UPS Express Saver" which probably was incorrectly autocompleted. 

Unlike Bing Maps, Azure Maps allows for traffic tiles to be rendered over top the standard map tiles. Please bring the traffic layer back with Azure Maps Traffic Tiles!

With a picture of original size like this : width 2 800 and Height 1376. On the screen the picture is around 470 by 230. If I go to the Image Editor, it shows me the picture size itself but not the area size used by the picture. It is a good thing to have the original picture's dimension but we work with the dimension used in the document. So, could you do something to resize the picture used in the document.

In my samples, you'll see my picture in a document (ie1), what I see when I go in the Image Editor (ie2) and, when I go to the Resize section (ie3). Suggestion, put the original image's dimension on the top of the right corner in the resize section. The width and Height should show the dimension in the document.

Thanks a lot, 

I want to draw the signature box, like in Adobe Acrobat Reader.

This is very important when the document needs more than 1 signature.

It looks like the `Fluent` themes may not properly theme the Non-Editable RadComboBox control.

Within the default style for RadComboBox within Telerik.Windows.Controls.Input.xaml, there exists a RadToggleButton with the name "PART_DropDownButton" which is part of the main control template. This toggle button uses the style "NonEditableComboToggleButtonStyle", which then sets the toggle button template to the "NonEditableComboToggleButtonControlTemplate" control template.

This control template has a Border named "ToggleButtonBackground" where to background is set to a template binding. However, the NonEditableComboToggleButtonStyle does not set background, and it therefore leads to a control that looks like the attached image.

This can be fixed by overriding the RadComboBox style, but it isn't simple to set the background on the ToggleButton, so you need to create custom templates and style to do it.

Having Problems with unreadable Tabs in RadPaneGroup: TabsSqueeze.png

I think I found a Solution with OverflowMode and ScrollViewer:

<telerik:RadPaneGroup x:Name="DocumentGroup" ScrollViewer.HorizontalScrollBarVisibility="Auto" OverflowMode="Scroll">

Problem:

After Loading Layout the OverflowMode is not respected anymore.

I found this ticket in Silverlight, what discribes the Problem and is approved: Docking: I would like OverflowMode to work for all RadPaneGroup in xaml/codebehind and this be persisted through SaveLayout/LoadLayout

And i found this documentation, which say, using OverflowMode can lead to unexpected behaviors:
https://docs.telerik.com/devtools/wpf/controls/raddocking/general-information/not-supported-properties

so i report this as a feature instead of a bug.

Please sea atteched an example project: TabWrapProblem.zip
Usage: Save and than Load the Layout -> Scrolling of tabs break

This sample project is not exactly the same as my actual project, but has the same issue.

I have multiple maps visible. I have a PolygonData that I want to be visible on both maps. It shows up fine. However, the polygon on the first map will not scale when zooming with the FIRST map. If I zoom with the SECOND map, both polygons will correctly scale.

If I replace PolygonData with my own object (PolygonVM), both polygons always correctly scale.

Add support for formats which can present numbers with non-arabic numerals, for example:
- Bengali - [$-bn-IN,500]0
- Devanagari - [$-hi-IN,400]0
- East Arabic - [$-ar-SA,200]0
- Persian - [$-ar-SA,300]0
- Gujarati - [$-gu-IN,700]0
- Kannada - [$-kn-IN,B00]0
- Khmer - [$-et-EE,1200]0
- Lao - [$-lo-LA,E00]0
- Malayalam - [$-ml-IN,C00]0
- Mongolian - [$-mn-MN,1300]0
- Burmese - [$-my-MM,1000]0
- Oriya - [$-or-IN,800]0
- Tamil - [$-ta-IN,900]0
- Telugu - [$-te-IN,A00]0
- Thai - [$-th-TH,D00]0
- Tibetan - [$-bo-CN,F00]0

Images decoded with CCITTFaxDecode filter affect the performance when showing the document.

We have a WCF service that continuously polls a database for new/updated items and sends them to WPF clients.  The client will process the update, decide what to do and then add/update an item that is displayed in a RadGridView.  We use an IEditableCollectionView on top of an ICollectionView.  Exception detail is below.

App just crashed while sitting idle on Zarate,

No mention of MSCORLIB so I think its a different error.

Data:

Currently, the control relies on its IsLoaded property to determine if it should render its items (axes, data points, annotations, etc.). However, if you measure and arrange the control in code without adding it into the visual tree, the IsLoaded property is not set to True, therefore the chart is not rendered and the image gets empty.

Original description
----------------------------------

Title: RadCartesianChart incorrecly rendered

We're rendering (Telerik) charts in code behind, to include them in a dynamic documentation.

For most controls it works fine - using standard methods (rendering control with System.Windows.Media.Imaging.RenderTargetBitmap and saving the result BitmapSource to disk)

However, it's impossible with RadCartesianChart with CategoricalSeriesDescriptor or ChartSeriesDescriptor. What we are able to get are axes and descriptions, but not bars.

I'm attaching an example - MainWindow displays a chart. I try to also create the chart in code behind. 
In CreateAndSaveChart() method I create a chart with a DataContext, then I call Measure and Arrange methods on it. At this stage the control should be properly initialized and ready to render. (For simplicity I omit rendering control with RenderTargetBitmap - you can preview the control with WPF Tree Visualizer, which will give you the same result). Well, if you preview the control at this stage, you'll see that the chart is missing bars. 
Next I create a new Window with my chart as a content, and display it for a while. Now the chart is fully and correctly rendered. As a workaround we display some Telerik chart in a transparent window to fully render, but such a workaround was reported not to work for some clients and is unacceptable in a long run. With most of Telerik charts we don't have such problems.

Other issue:
- for other Telerik charts we need to wait a few seconds to have it fully rendered. It's be better to have an event informing that the control is ready. 

I'll be happy to add more details if you need any.

* While experimenting with the example I've suddenly managed to render the chart with bars, but this time the rendered size was incorrect (very small)

After upgrading to Telerik WPF 2019.1.116 from 2018.3.1010 we receive a lot of:

System.ComponentModel.Win32Exception (0x80004005): Invalid window handle
   MS.Win32.UnsafeNativeMethods.GetWindowText(HandleRef hWnd, StringBuilder lpString, Int32 nMaxCount)

Exceptions. It makes out application very slow.

In version 2018 everyting was OK. See attached scerenshots.

I would like the fluent theme to support spacing option like it does fonts. The Mail app added a new setting "Folder and message spacing" in which you can pick spacious , medium, or compact. I would like the fluent theme to support something similar.  The fluent theme was defined for "finger" access but we still have desktop apps that want dense information with mouse access.  I would normally just pick a different theme but because of Windows 10, I can't. Windows 10 no longer supports specifying a default font and WPF no longer defaults to the OS font. This means that all my Windows apps must support picking a font. So I'm stuck with the fluent theme. But I don't always want the "spacious" spacing that the theme uses.

Would it be possible to support picking "spacious", "medium" or "compact" spacing?
