What about supporting INotifyCollectionChanged data source for the Grid?
This request is marked as declined only to avoid duplication and clutter, support for INotifyCollectionChanged will be implemented for our next feature release. Please follow the other item to get notifications.
There are other important scenarios that also need to be handled and the solution is not simply attaching to the change event of the collection. Here are two examples:
@Martin, INotifyCollectionChanged should be primary scenario for the following reasons:
1) INotifyCollectionChanged support is already implemented in WPF and Xamarin
2) INotifyCollectionChanged allows to use custom implementation (or 3-rd party) of filtering, sorting and requesting of data
Regards to filtering and sorting see my project: https://github.com/IgorBuchelnikov/ObservableCalculations
This is already logged in the following page and we have it under consideration (I have already added your Vote for it, you can also Follow it): https://feedback.telerik.com/blazor/1409112-the-grid-does-not-update-on-data-source-change.
Whether such an interface, or a method like .Refresh() will be implemented on the grid is too early to say, as we have a lot of scenarios to consider (including, for example, manual filtering, sorting and requesting of data).
Thus, I am closing this as a duplicate of the other one.
