The error above will occurred in KryptonNavigator when I add the control in a split container (KryptonSplitContainer) and change the mode into "Outlook Full"... Perhaps it's helps!?

Same Issue to #1243
Sorry, can be handle in that thread.

Hi @DarthVader85PA

I think this has been fixed in v90, please retry using the either the latest nightly or canary build.

Hi @Wagnerp

I have installed Canaray, latest NuGet build. The bug in the designer still exists. Of course: only when I change the Mode-Property to Outlook - Full. My workaround: I set the property Mode to Bar - RibbonTabs and change it into Outlook - Full on runtime in Sub New.

Error in Designer:

Change Mode in runtime:

Hi @DarthVader85PA

I'm unable to replicate using the latest alpha build. Can you attach a demo project so I can take a look?

[DarthVader85PA]

Hi @Wagnerp and a happy new year to you,

here my Demo, created with:

• VisualStudio 2019 Professional 16.11.32
• .NET-Framework 4.8.09037

Hi @DarthVader85PA

Thanks for sending over a sample, and happy new year to you too. Unfortunately, I still can't replicate the issue, is it possible to attach a screen recording?

Here my Error-Video.
I hope it helps?

Hi @DarthVader85PA

Thanks for the reply, I've repeated the same steps on my latest 'dog fooding' (90.24.1.2) build in VS 2022, and it seems to be ok. Not sure if there might be a config issue, but the next nightly build is scheduled to drop next Monday 8/1. Would you mind retesting then?

Hi @Wagnerp

I don't know but I tested it with VS 2017 Pro, VS 2019 Pro, VS 2022 Community. Same issue in each VS-Edition.
After I clicked OK, VisualStudio will crashed and restart. I removed canary-Nuget-Package and installed nigthly-Nuget-Package again.

For your info: I created all my WinForms-Projects with .NET-Framework (Ver. 4.8), NOT .NET-Core:

New Project => Language: VB/C#, Plattform: Windows, Project-Type: Desktop => Select Windows Forms-App (.NET-Framework) => Next => .NET-Framework-Version: 4.8

I will test it again next week.

Do you use Nuget-Package?

Do you use Nuget-Package?

No, I directly linked it, but testing it with NuGet now

Thanks a lot.
Another question: What happens in this Sub:

Standard-Toolkit/Source/Krypton Components/Krypton.Toolkit/Controls Toolkit/KryptonGroupPanel.cs

Line 474 in 4c38c84

protected override void OnVisibleChanged(EventArgs e)

In this sub occured this error: a null check fails: Object reference was not set to an object instance

Something weird happens in VS 2022, it doesn't crash?

That has appeared to have been resolved since

Hi @DarthVader85PA

Please re-test using todays nightly, build .8

[DarthVader85PA]

Hi @Wagnerp

I have updated to latest nightly build (NuGet). Good news: It works. :)
So now we can close this post and #1243 too I think. Thanks a lot!
