Hi Ran,
Thank you for reaching out to us.
The namespace change from ‘C1.Win.C1FlexGrid’ to ‘C1.Win.FlexGrid’ is required, and unfortunately there is no alternative way to avoid updating the code. This change was made to unify and standardize the ComponentOne packages, improve maintainability, and ensure smoother updates in future releases.
Since the old namespace is no longer supported, all explicit references need to be updated to the new one.
To reduce manual effort, we recommend using Visual Studio’s Find and Replace (Replace in Files) feature to replace ‘C1.Win.C1FlexGrid’ with ‘C1.Win.FlexGrid’ across your solutions. This is the quickest and most commonly used approach for large codebases.
We understand this requires some effort initially, but it is a one-time change and will help with future upgrades.
Thanks & regards,
Aastha
