Visual Studio 2022 - Window design tools window doesn't show Wisej tools

0
0

I have developed an application using Wisej.net and it has worked well.  Now, when I go into design mode on a window and try to add i.e. a textbox or other control, there are no Wisej options.  This just began happening within the last week.

When I try to open any window (form) in VS, I get the error “Value cannot be null. Parameter name: instance”.  If I add a Windows form, the new form does not get this error, but also does not have any Wisej controls within.

When I compile my application with Wisej windows/forms defined (which I can’t open to edit), everything compiles and runs fine…

Any suggestions on how I might re-install or otherwise get them to show?

Microsoft Visual Studio Community 2022 (64-bit) – Current
Version 17.14.14

Microsoft .NET Framework

Version 4.8.09032

Thanks in advance.

I just uninstalled the WiseJ extension and re-installed it. No error mentioned above, but still no Wisej controls in the toolbox.

I even created a new WiseJ project and it also did not have tools.

I’ve installed the .visx half a dozen times, including downloading new installers each time.  I even uninstalled the extension and re-installed it.

no happiness yet.

further advice?

Strangely enough…In one of my other TEST programs, the Wisej does show up in the Visual Studio design toolbox…  I can even copy a control from this application and paste it successfully in my new application. But, alas, the Wisej controls still do not show in the toolbox within.

    Hi Rusty, I can’t reproduce on my end at all, can you please wrap up the app that fails for you and send it over via email to support[AT]wisej.com?

I don’t see any menu like yours on my version of Visual Studio 2022.

I might add that I tried upgrading to WiseJ 4, but there were too many issues, so I reverted to 3.

Using NuGet manager, I removed all wisej DLL’s and re-added WiseJ 3 DLLs, could this be a problem?

 

I just created a NEW project in VS 2022, selected a Wisej web application, opened Page1 and it says: the designer could not be shown for this file because none of the classes within it can be designed….   the base class system.void cannot be designed.

    Hi Rusty, you’ll need the vsix for 3.5, the menu I was referring to can be found when you open the Wisej designer. What issues are you referring to when going to Wisej.NET 4?
  • Rusty Elston
    when I tried to run the vsix, it said it was alread installed. When I tried to start the application, it said (and this is new since I tried to run the visix), “Visual Studio stopped responding for 21 sceconds. Disabling the extension Wisej.Net 3.5.23 might help”

Hi Rusty,

You can use our built in “Update ToolBox” feature in the designer to populate the ToolBox.

I have attached a screenshot so that you know exactly where to find it.

Btw, if the issue is with using the Net Core designer, then I’m afraid that it’s an issue that comes with Visual Studio, as you have to clean the solution, close VS and then reopen it to rebuild the solution for the toolbox items to show up.

HTH,
Alaa

Actually, I jumped the gun…     The windows with Wisej controls now OPEN successfully (where the wouldn’t before visx), but the toolbox still doesn’t have Wisej controls listed.

I tried “Choose Items” and none are listed.

Any new suggestions?

Thanks in advance.

🙂  Yes, that was it!    I don’t know how it was no longer installed…maybe it’s sun-spots 😉

 

Thanks!

Hi Rusty,

You’re missing the VISX for Wisej.NET, please download the latest one from https://wisej.com/builds/

Best,
Alaa
