Hi David, 
 
Thanks for contacting Syncfusion Support. 
 
We have checked the reported query that the CardView not updating properly. We can’t replicate the reported issue from our side, the CollectionChanged event gets triggered properly when the source changes and the cardview gets updated properly in the UI. Please check the sample and the video for your reference. 
 
 
 
If we misunderstood your requirement, get back with more details on it. If possible, please share the issue reproducing project file and the video for the same.

Please see altered version of the code you attached previously, I have added a button which modifies data in one of the CardViewModel Objects and even after adding another item it don't pick up this change to an age of 99 for the first item which i can see has changed from looking at the data when breaking on adding another

I should probably also point out that there is a flaw in the .net collection modified logic and it don't pick when you change an item only when you add or remove and possibly replace (Not tried that yet.)

Hi David, 

Thanks for your update. 

We have checked the reported query with the updated sample and found that you have created an Age property but not used RaisePropertyChanged to get notified whenever the property gets changed. We have modified the sample where the values of Age updating properly. Please refer the sample for your reference.
