Hi.

I am playing around with a trial version of the WinForms suite. There are a couple of issues I am seeing from the start and haven't been able to find a solution, so I was hoping posting here might lead me in the correct direction.

First: Telerik UI for Winforms > Convert to Telerik Controls crashes Visual Studio 2022 (.NET 8)

I have a simple solution with one Form (not the Telerik version). I also have one RadGridView and one Windows DataGridView.

Doesn't matter what I try in the conversion wizard, VS2022 crashes. I tried selecting a subset of files to convert (the list of files never displays), tried selecting only DataGridView and tried selecting all control types. All result in VS crashing with no conversion having taken place.

I searched the Telerik Knowledge Base and the best I could find seems to indicate VS2019 is a requirement. And if you suffer from crashes, that solution only goes back to VS2017. I downloaded the converter and I can only select VS2017.

https://docs.telerik.com/devtools/winforms/knowledge-base/converter-exception

I tried attaching the ZIP file but it is 33MB and that is too large. The solution only has one form and two grids. With very basic hard-coded data to load (which I took from a Telerik tutorial).

Second: Adding a RadGridView to our existing .NET 8 WinForms project results in VS2022 freezing when I try to rebuild the solution.

I can't include code for this one. What I did was add a NuGet package to: Include="UI.for.WinForms.AllControls.Net80.Trial" Version="2024.2.514"...

I dragged a RadGridiew onto an existing Form that had a DataGridView. I then copied whatever loading I do for the DataGridView and bind the same List (around 100 rows) to both grids.

If I try to rebuild the solution, once it gets to the project containing the RadGridView VS2022 will freeze.

However if I run the solution, I see the grid loaded an populated

Thanks for any insights.

Hi guys!

I am working on a project with some Telerik components but I can not display the designer view in VS2022. There is no error, but the designer only displays the components without the final result (see image) so I can not move or render as I wish

I have tried installing the DLL in my GAC as suggested in other posts but still the same.

Any idea? 

Hi

Every day, I get an error when I try to open the designer of a form in VS2019.

The error says: Visual Studio stopped responding for 22 seconds. Disabling the extension Progress Telerik UI for WinForms 2020.2.612.1 might help.

I have tried a few things like "Lauch Toolbox configurator" which seems to solve the issue for the day but the next day (after a reboot of the computer), the same error is thrown again.

How can I solve the issue and improve the performance at the same time (because showing a form in the designer takes a while)?

Hello,

I'm having trouble installing Telerik UI for Winforms (version 2023.1.314) on Visual Studio 2022 (version 17.0.5).

When I install the extension I get the error in the attached screenshot. I'm able to make the error go away temporarily by deleting the contents of %localappdata%\Microsoft\VisualStudio\17.0_001382ae\ComponentModelCache. But I still get errors when I try to build the solution that already contains Telerik components indicating that I am missing an assembly reference.

Also, many components in the toolbox don't actually get added to the form when I try to drag and drop them in. 

I've tired uninstalling and reinstalling Telerik several times and running the repair function on the Telerik installer.  When available I've tried running the Toolbox Configurator and the Upgrade Wizard but neither have made any difference. Most often the Telerik menu doesn't populate with either  (see menu screenshot attached). 

I've had this nagging error for the last few months with Visual Studio 2022.  

  Visual Studio 2022 stopped responding for 88 seconds. Disabling the extension Progress Telerik UI for Winforms Extension 2202.3.921.3.

The seconds shown are grossly underreported and exceed 180 seconds. I disabled it through Extensions>Manage Extensions.  The freezing has stopped.

VS2019 is not exhibiting this behavior.

Hello everyone,

I'm running into a peculiar issue with VS Community v17.0.4 2019 and the Telerik Extension.  When I attempt to launch the Upgrade Wizard (or most of the other options):

I get the following error to pop up:

Here is the full stack trace from that dialog as well:

Failed to execute command.

I removed the extension & re-installed it, but the issue still persists.  Has anyone else seen this error before?

I get this message when starting Visual Studio.

message: Visual Studio stopped responding for x seconds (x s anywhere from 6 to 20).

Disabling the extension Progress Telerik UI for WinForms Extension 2023.1.113.1 might help.

Microsoft Visual Studio Enterprise 2022 (64-bit) - Preview Version 17.6.0 Preview 1.0

and previous versions also.

Also previous versions of UI for WinForms.

It does not matter if I am working on a WinForms project or not.

Works find after that.

When I open a solution in Visual Studio, it often goes into a non-responsive state, with the following report:

The product I use is Telerik WinForm and it is in Trial status.

The Korean message below is translated into English as follows.

"This may cause Visual Studio to become unresponsive. Disabling extensions can improve your experience. Frequency: 6 reports from last week."

I am getting an error after I upgrade to WinControls.UI Version 2022.2.622.40
