Empty Rect error occurs during Diagram.Align

The Situation when I will drop and add a shape. before added shape drawing on the diagram, I want to execute Diagram.Align() method with all shapes.

In Detail, I will drop and add ContainerShape into another ContainerShape.

Another ContainerShape has a child, a shape.

After Dropped and Added, I try to Align ContainerShape's Childrens when Other ContainerShape calls "OnItemsCollectionChanged"

but, if i try to Align with dropped shape. it occurs to Empty Rect Error.

"Empty Rect cannot modify this property"

e.StackTrace " location: System.Windows.Rect.set_X(Double value)\r\n location: Telerik.Windows.Diagrams.Core.GraphController.AlignShape(IShape shape, Point oldPosition, Point alignedPosition, Alignment alignment)\r\n location: Telerik.Windows.Diagrams.Core.GraphController.AlignShapes(Alignment alignment, IEnumerable`1 shapes)\r\n location: CloudRPA.Views.Diagram.DiagramContainerShape.ReArrangedItem(Boolean isAdd)"

Capture Print Event

Hi guys,

I'm trying to capture the print event of a RadPDFViewer to not only print the PDF but also save it to a predifined location everytime it is printed.

Ithought about the Click event in the toolbar, but I also need to capture it if printed from contextmenu.

I have read something about inherit the print command, but I haven't gotten how to do that.

Greetings,

Benedikt

ComboBox does not bind "TextProperty" anymore

<telerik:RadComboBox IsEditable="True" IsTextSearchCaseSensitive="False" Text="{Binding SchoolEducation}" ItemsSource="{Binding SchoolEducations}" />

Hi,

since Release 2020.1.218 the TextProperty-Binding does not refresh my property in my ViewModel.

I also tried the current internal version.

Best regards,

RadDocking Layout Validation

Hello!

The right behavior for using panes in Docking is like that: we set/modify PanesSource property, Panes property is initialized by using PanesSource and DockingPanesFactory, panes are created or removed. But when set PanesSource, try to load invalid layout and get an exception, Docking.Panes property is set to null and actual panes is not removed, because we don`t have them in Panes property. This behavior cause problems with resolving panes (because there are old panes in memory, that should have been removed). Can you suggest some sort of validation for layout or ways to clean old panes from memory?

Null value on currentAssembly.GetManifestResourceStream()

Hello,

yesterday I installed the latest Visual Studio 2019 update and now I'm getting in the line

var dllStream = currentAssembly.GetManifestResourceStream(fullDllName);

a value of null (called in CurrentDomain_AssemblyResolve()). It was working good all the time.

I'm using the code posted here:

https://www.telerik.com/forums/how-to-display-controls-(like-radwindow)-at-design-time-when-noxaml-is-used-and-implicit-style-resources-are-in-a-custom-dll#Pz5cUcqhtk-t3EQHJuJYHg

public class TelerikThemeUtilities{

static TelerikThemeUtilities() {

AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;

}

public static void Initialize() {

}

public static bool GetDesignTime(DependencyObject obj) {

return (bool)obj.GetValue(DesignTimeProperty);

}

public static void SetDesignTime(DependencyObject obj, bool value) {

obj.SetValue(DesignTimeProperty, value);

}

public static readonly DependencyProperty DesignTimeProperty = DependencyProperty.RegisterAttached(

"DesignTime",

typeof(bool),

typeof(TelerikThemeUtilities),

FrameworkElement element = target as FrameworkElement;

LoadTelerikTheme(element.Resources, "Crystal");

}

public static void LoadTelerikTheme(string themeName) {

Application.Current.Resources.Clear();

LoadTelerikTheme(Application.Current.Resources, themeName);
