New ComponentOne Branding

You may have noticed a new look across all GrapeCity products! We've updated all of our developer solutions product lines to better reflect the full family of products. Over the next year, we'll continue integrating the new brand into ComponentOne's demos, documentation, and installers, and improve the UX and performance, as well.

.NET Standard Support

We rolled out some .NET Standard support in our last hotfix, but we’re taking it a step farther for the v1 release. In addition to targeting .NET Standard 1.1 for our controls, we’ve updated our samples to use .NET Standard projects instead of PCLs. Now that Xamarin.Forms 2.4 fully supports .NET Standard, we expect that the platform will quickly move in this direction, and we’re excited to be at the forefront!

We’ve added new editing features to our CollectionView control to make it easier to interact with and update an attached datasource, and we’re including a new SQLiteDatabase sample to demonstrate how you can easily use these editing features to update your local database using the C1CollectionView and FlexGrid.

Also, we’ve added support for Xamarin.Mac to the C1CollectionView, and we’re providing a set of CollectionView101 samples to show off using the control. Let us know if you have interest in more Xamarin.Mac controls in the future!
