When trying to debug my Application according to your manual (https://docs.telerik.com/devtools/winui/getting-started) this error appeared in my Debugging Session:
| Name | Wert | Typ | |
|---|---|---|---|
| ▶ | Exception | {"Error HRESULT E_FAIL has been returned from a call to a COM component."} | System.Exception {System.Runtime.InteropServices.COMException} |
It happens when I'm trying to set the ItemsSource of my DataGrid.
I'm using the same declarations as described in your manuals example of using a DataGrid.
I've configured my environment according to the following specifications:
Visual Studio 16.11.1
Project Reunion 0.8.2
Telerik UI For Win UI 0.4.0 | I'm referring to the Win32-Assembly of Progress Control Panel
Are there any known issues with the current setup of 0.4.0 as described in this link (https://www.telerik.com/forums/is-winui-in-desktop-currently-supported)?

Hi,
My Setup:
Installed WinUI 3 Preview 4
Created a new project based on the "Blank App, Packaged (WinUI in Desktop)" template
Added a project reference to Telerik.WinUI.Controls.dll
Changed MainWindow.xaml to
<Window>...
<Grid>
<telerikGrid:RadDataGrid x:Name = "MyGrid />
<Grid>
<Window>
this is when I get the error message:
A value of type 'RadDataGrid; cannot be added to a collection or dictionary of type 'UiElementCollection"
Is my scenario currently supported?
If yes, what else do I need to do to get this to compile?
If no, when will my scenario be supported?
Thanks
Michael
Hi,
Can I achieve this with preview 3 ?
