Hi,
I have a RadGridView that uses DataContext="A" and I want for one of the GridViewDataColumn to use other DataContext="B".
I would be happy if you could explain to me how to do this.
Thanks
Hello,
I'm using a notifyIcon in my application and it doesn't work, but I saw that also the samples included in "Progress Telerik UI for WPF" don't work.
Maybe there is a windows 10 setting? I look in the settings of tray notification area but I didn't see any setting that can disable the working.
Thank you
Luigi
Hello
I did manually converted a .NET Framework 4.7.2 to .NET Core 5.0. I did the conversion by editing the .csproj files using Sdk format.
I have Telerik WPF libraries (2021.3.914) installed locally, and the project refers to the local DLLs.
I don't get any design-time error. I can even see the preview of the page and controls in the designer.
When I run the app I get a runtime error.
System.TypeInitializationException: 'The type initializer for 'Telerik.Windows.Controls.TelerikLicense' threw an exception.'
MissingMethodException: Method not found: 'System.ActivationContext System.AppDomain.get_ActivationContext()'.
I have two projects running side by side: the .NET Framework 4.7.2 runs fine, .NET Core 5.0 fails.
Thanks

Hello
I am trying to convert a .NET Framework 4.7.2 (Prism) application to .NET Core. I am trying to use the Telerik WPF Project Converter, but I am hitting this error right after I click "Next" on the first screen of the wizard.

This is the message:

Hi,
I have 2 RadWatermarkextBox in a RibbonGroup. When I Tab in the first, I want to be inside the second one but doesn't seem to work (even with telerik TabExtensions)
Any ideas?
<telerik:RadRibbonGroup Header="Filtrage">
<telerik:RadOrderedWrapPanel VerticalAlignment="Top">
<telerik:RadWatermarkTextBox WatermarkContent="First" />
<telerik:RadWatermarkTextBox WatermarkContent="Second" IsTabStop="True"/>
</telerik:RadOrderedWrapPanel>
</telerik:RadRibbonGroup>I've just updated Telerik and are now getting this compile time error:
Severity Code Description Project File Line Suppression State
Error XDG0047 The specified value cannot be assigned. The following type was expected: "IFilteringControl". Modelkatalog.Client C:\develop\data-tool-modelkatalog\Modelkatalog.Client\Controls\List\CarVariantsList.xaml 1
I'm getting this error from 2 XAML documents that both implement a custom Fitler for the RadGridView
I didn't get this error before, and I'm still able to compile and run the project - which kind of defeat the purpose of [Severity: Error]
I'm trying to be able to expand nested properties programmatically. Specifically, I have two RadPropertyGrids next to each other for the purpose of comparing two objects and if I expand a nested property on one object I'd like to have the nested property on the other object auto-expand to keep the two views in sync. I'm trying to accomplish this by binding the IsExpanded property of the two property definitions together. This only partially works. When you click the + button to expand a nested property, the corresponding property on the other object disappears. If you click again the corresponding property reappears and they are both collapsed. If you click a third time they both expand as expected. It works correctly from then on. Just the first time is the problem.
This problem even occurs if you remove the RightGrid and just use the button to programmatically change the IsExpanded field. On the first click the property disappears completely. Subsequent clicks work as expected. If you click the + icon on the property itself it works fine.
I need to be able to set PropertyDefinition.IsExpanded programmatically at some point after the PropertyGrid is displayed. Setting it during AutoGeneratingPropertyDefinition is not an option.
I'm using version 2021.3.1109.
