While trying to update to latest version of Telerik ASP.Net Ajax, we are getting following exception:

An error occurred while running the wizard.

I would request to have the upgrade wizard handle it and show a graceful message instead of throwing the exception as it is doing right now.

When creating and upgrading Telerik UI for AJAX projects to version 2025.1.211 using "InstallFolder" distribution Telerik UI for ASP.NET AJAX references are not added to the project.

When you have a Visual Studio solution with 1 or more Telerik AJAX projects and one or more non-web projects, the upgrade wizard does not list any projects.

Steps to reproduce the behavior:

1. Create a new Telerik AJAX project with target framework 4.7.2 or 4.8
2. Add a new class library project with target framework 4.7.2 to the solution.
3. Select the solution file.
4. Launch the Upgrade wizard from the Telerik main menu.

Expected behavior
The Upgrade wizard should list projects

Suddenly all my projects tell me to 'Convert to Telerik Web Site' but they all are already are?

All projects are affected. If I try to convert and choose a different skin this seems to affect the installation, but the button 'Convert to Telerik Web Site' is still visible.

Is there a way to fix this?

The menu commands for Telerik projects sometimes are not visible. The reason why is that the visibility state of the commands is evaluated asynchronously. Depending on the time it takes to evaluate the command state, sometimes the commands are not available when they are queried for the first time.

NOTE: It can be observed in all Telerik products.

Due to wrong project type detection, most of the menu and context menu commands are not available for web application projects.

The following commands are missing:

- Configure project
- Add [DPL] references
- Add Telerik Scenario...
- More Scenarios...
- the commands for individual scenarios
- the project context menu

 

The following commands are available but are not expected to be available:

- Create New Telerik Project

After upgrading my Telerik Ajax version from 2020.3.915.45 to the latest 2021.2.511.45 version, I am now receiving this error, in my solution. The error occurred right after I tried to upgrade Telerik from inside Visual Studio. BTW, I do not have this file: web.config.transform I am also getting a similar error when I go to this:
Configure Telerik section in Visual Studio (see screenshot).

Failed to execute command.

Hi

I got this dialog pop up when it was trying to upgrade my solution which had a few web sites in it.
It seemed to get lost. I dont know what the VS dialog with 'Description'  is all about.
Not sure what triggers it to say it needed an update and yet there is nothing to update.

Its possible that there is a backup folder that it created from a previous upgrade and it is looking at an old DLL in that project.

Anyway, sure you will sort it out :)

 

Thanks

Doug
