When merging the ReportViewer's WPF theme dictionaries from the DLL in App.xaml, the VS2019 Designer fails due to a problem with a ZoomComboBoxStyle definition.
This causes all Telerik UI for WPF control's styles fail to load in the Visual Studio designer.
WORKAROUND
Instead of App.xaml, merge the ReportViewer's theme dictionary closer to the control.
For example in the ReportViewer's direct parent:
<Grid><Grid.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<!-- Moved from app.xaml -->
<ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Summer/Telerik.ReportViewer.Wpf.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Grid.Resources>
<tr:ReportViewer x:Name="ReportViewer1" ReportSource="{Binding CurrentReport}" />
</Grid>
When the culture of the thread is the default one, the private font (e.g. "Shadow Brush") will be replaced with a substitute in the Html5 Viewer (e.g. "Verdana") as the viewer does not respect private fonts. This is normal and expected behavior. When exported to PDF the text is displayed with the correct font ("Shadow Brush") but the embedded font as claimed by the Font properties of the PDF document reader is the substitute font ("Verdana").
When the culture of the thread is changed, the private fonts are not respected and not embedded in PDF rendered document at all. The text does not appear.
In HTML5 Report Viewer it is possible to intercept a client request (e.g. the request to export a report to a particular export format) and modify it like this:
{"format":"<script>alert(1)</script>","deviceInfo":{"enableAccessibility":false,"enableSearch":true,"BasePath":"/COAT_SIT/api/reports"},"useCache":true,"baseDocumentID":"31d0a1ca0162a3f13e92bf"}
The malicious script will be executed when the error message for a missing export format is displayed in the viewer.
Under Linux, when the font is set with Conditional Formatting some of the TextBoxes may be rendered with different that the expected Font in Docx. Other TextBoxes set with the same rule to the same font are rendered correctly.
The same report rendered in Docx under Windows produces the correct document.
I have an asp.net core web app that works fine running from VS 2019 and IIS Express. However, if I run it under a docker windows container, there's an error when deserializing the xml .trxd file.
Exception thrown: 'System.TypeInitializationException' in Telerik.Reporting.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in System.Private.CoreLib.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in System.Private.CoreLib.dll
Exception thrown: 'System.MissingMethodException' in Telerik.Reporting.dll
This is only happening when running in a windows docker container.
Please do some testing with this configuration.
The pinch zoom feature on mobile devices is not working as expected.
- On iOS devices, the zooming is fidgety, zooming is not accurate where the pinching gesture occurs.
- On Android devices, Zoom In on the report will take the page to the top left.
