I've just installed Infragistics on a new laptop and created an application. Everything seemed fine but yesterday and today I open the project and I am not able to select or edit any Infragistics controls. I ran Update-Package to see if that would fix anything and I was able to work with Infragistics controls again.
Then it went weird while customizing a toolbar and now I am at an even worse point because none of the columns in my grid exist anymore. The screenshot is from when the problem first started and now it's worse as none of my stored columns exist.
Is there something I am doing wrong? It's extremely frustrating to never know when my application is going to be rendered useless.

Hello,
Thank you for your post. I would like to know if you using dlls or packages in the application?
Also if you created .netframwork application or .net8/9 application ?
In Winforms, you can use packages for ,net core /.net8/9 applications and dlls for ,net framework 4+ application only.
Looking at the image you shared with the email , all your controls are at the bottom tray , this makes me think that this is missing designer dlls issue , 1st remove all the entries from your .licx file and also select all the dlls and rightclick open property window set specific version to false , copy local to false , clean and rebuild the application .Like this (for example)
This should fix the issue.
In the Infragistics installation folder, ensure the design-time assemblies (often named something like Infragistics.Design.[Product].dll or similar) are present for the version installed (25.1.63). If they’re missing or wrong version, Visual Studio design surface cannot fully load controls.
