Scan.cshmtl via View:

@(Html.Kendo().Grid<Main_Kendo.Models.ScannerViewModel>()                <---  Html.Kendo gets red underline error ??? 

.Name("Grid")         

.Columns(columns =>         

{             

columns.Bound(b => b.Scan).Width(140);             

columns.Bound(b => b.BarcodeImage).Width(140);             

columns.Bound(b => b.DropZone).Width(140);             

columns.Bound(b => b.EnteredBy).Width(100);             

columns.Bound(b => b.EnteredDate).Width(130);             

columns.Command(command => command.Destroy()).Width(110);         

})

Whatever below.... 

)

 

The error message:

HtmlHelper <dynamic> doesn't contain a definition for Kendo and no accessible extension method for 'Kendo' accepting a first argument of type HtmlHelper

Already have ScannerViewModel in Models folder, Kendo.Mvc was missing references that I added.

This problem is back with the latest version of Telerik UI R2 2021 (2021.1.119).

After updating the packages using the Telerik Control panel no projects will build om Visual Studio 2019 and Nuget packages will not install. 

 

C:\Program Files\dotnet\sdk\5.0.102\NuGet.targets(131,5): error : The local source 'C:\Program Files (x86)\Progress\ToolboxNuGetPackages' doesn't exist.

The workaround is to manually create this folder: 'C:\Program Files (x86)\Progress\ToolboxNuGetPackages'

In order to upgrade to new versions of products I have to uninstall all the existing ones, first. This takes a hundred years and is ridiculously slow.

Add an auto-uninstaller for updated products selected to be installed. That way, I can run it all overnight and, hopefully, it'll be done by morning.

Thank you.

After I update Telerik Control panel and several products (no issues reported).  Then I went to open one of my UI for WPF projects and/or UI for UWP projects and VS 2019 starts to load the project then just gets into a "Not Responding" state.  Waited 15 minutes, still same not responding so I had to "end task".

Any ideas of what the Telerik updates may have done to my VS environment?

Cheers, Rob.

I have configured the Control Panel to install my Telerik selection into "V:\Telerik".One entry in that directory is a folder "ToolboxNuGetPackages".

Last night I updated the Telerik libraries to the current version using the Progress Control Panel. A few minutes ago, I created a new solution for a WPF netcoreapp (in Jetbrains Rider), added references to the required Telerik libraries and tried to build the otherwise untouched solution.

It failed during the ResolvePackageAssets task, because nuget was unable to find the fallback package folder "C:\Program Files (x86)\Progress\ToolboxNugetPackages".

With a bit of help from StackOverflow I found that this setting is defined in the file "C:\Program Files (x86)\NuGet\Config\Telerik UI for WPF.config", and I for one did not put it there. In fact, I had changed it a few days ago,while investigating some other build failures; after all, it was a non-existing path, so things could not get worse. Now, after the update, the original path is back ... and as installer the Control Panel is my prime suspect.

So I'd like to ask somebody at Telerik to check if the Control Panel does write the contents of that file and if so, to make sure that it uses the actual location of the ToolboxNuGetPackages folder. 

In my case, I changed the path to "V:\Telerik\ToolboxNuGetPackages", unloaded and reloaded the project and it built without further problems.

 

I tried to submit this via the "Get Technical Support" item in my account page, but the UI is so user-friendly that submissions for the Control Panel are impossible there.

 

Kind regards,

Stefan
