Hi Nithya,
This issue most likely to happen when you update to a new version of ComponentOne Studio and something does not get updated properly.
To get the issue resolved please follow below steps:
- Remove all C1 references in your project and replace them with the version in C:\Program Files (x86)\ComponentOne\WinForms Edition\bin\v4.0 (sometimes some of the dlls are referenced from the ASP.NET versions, since they have similar names like those of WinForms edition).
- Also delete your VS toolbox items and replace them by selecting all the DLL’s from the same location above.
- Then, restart Visual Studio and build the project.
You should now be able to build & run your project and also add new FlexGrid(s) as expected.
If that does not help, please refer “Controls are not loaded at Design Time” heading in the following article discussing how to resolve this issue: https://www.grapecity.com/en/blogs/a-step-ahead-troubleshooting-common-errors-part-i/
Hopefully this would resolve the issue for you.
Kind Regards,
Ruchir Agarwal
