(After the Site has been assigned to the control. You are supposed to wait for your control to placed in the designer and then can check its DesignMode mode property. All Microsoft UI Frameworks after WinForms seem to have gotten such an API.Īlso suggest me is there any other way to find the Design mode in NET core projects. I understand that devs may want to have more fine grained distinction so I suggest a new API to be added to detect whether you are currently running in a design time process. The DesignMode API is designed for checking the direct user interaction, if you have a composite control the child controls are supposed to act as if they were hosted in a normal application. In particular if a control has child-controls neither is going to be set for them, though LicenseManager may leak through depending on how child controls are constructed. If you have a composite control you don't want to design the composition of the composite control, you want to design it as a whole. DesignMode is supposed to control design-time user interactions.

LicenseManager.UsageMode is supposed to tell you whether you need to check for the development or runtime license in the constructor.

None of those APIs will tell you whether you are running in a design-time environment, that is not their purpose. not their child controls if they weren't placed by the user)

DesignMode is setup after the control has been added to the design surface, but only for controls the user is actually currently designing (i.e.

LicenseManager is setup for the duration of the constructor call.

They are reliable for what they are designed, but you want to use them for something they are not designed for. Observe that none of them is 100% reliable

Observe that none of them is 100% reliable.

Try all 3 forementioned ways of checking if in the design mode.

Create a simple WinForms control and a WinForms app using it.

Ideally I would have a Property on the which would be completley reliable regardless of if it's used from constructor or not

If for any reason this won’t/can’t be done, please have the comments on these two properties (DesignMode and LicenceManager.UsageMode) explain all the caviats and details.

It will be always reliable, not only from constructor.

We won’t have both DesignMode and LicenceManager.UsageMode, but only one of these two.

I am not blaming anyone (I guess that’s clear?), I am just pointing to something which would be beneficial to improve on.

Various sources suggest the combinations of the previous 3.

However, if Visual Studio changes its process name it’ll stop working.

().ProcessName = "devenv" This seems clunky but seems to work for me (PR).

LicenseManager.UsageMode = LicenseUsageMode.Designtime This is also not reliable enough, at least from my experience, it Is sometimes false whereas it should be true.

Others suggest walking the parents up and checking the property. Some suggest its value is correct only in ctr after InitializeComponents.

ĝesignMode property is flag, but it doesn’t seem to be reliable.

The ways and suggestions I found from multiple sources (Stackoverflow and few of your team mates) are: It’s rather confusing and I think there is room for improvement.

I’d like to raise an issue with Winforms about the way to check if the current code is run by designer or not. Have you experienced this same bug with.NET UI component that still has to work in. Also annoying, admittedly, but that's what I've been doing for now (well, for other reasons as well, as we sell a. NET Framework project files around and do designer stuff with those. The other option is the still-recommended workaround of keeping the. Perhaps you have more luck with JetBrains Rider, although from what I've seen they simply host the very same designer in pretty much the same way as Visual Studio and thus are unlikely to fare any better here. So that's a twenty-year old codebase, perhaps on both ends (Windows Forms Designer and Visual Studio alike) that now somehow has to be moved to different processes and different runtimes. NET Framework the designer had to move out of process, as the only alternative would have been no designer at all. NET Core since the designer runs your own controls' code right during design time (pretty horrifying on one end, but also enables a fairly integrated experience with custom controls).
