Well. I got the same problem too.
I have read all suggestions and unfortunately, nothing seems to work.
I tried the following after a button click event is fired :
1- Redone the invoke datasource method and re-setting updating the collection property that the grid is bound to.
2- Invoking await gridx.Reload();
3- Calling the Page Reload method.
4- I even tried executing a c# code and called the page load function await load();
None have worked for me. Any Ideas ?
There is something worth mentioning here, In earlier Radzen studio versions where .Net 3.1 was supported, I have never faced this issue.
Not sure if anyone having this issue here is related to Entity Framework. If you use EF, you may want to look into whether EF is caching your data. To prevent EF caching, you can set it to AsNoTracking() or use the factory pattern DbContextFactory to create new client for each unit of work. Once the CURD operation is done, use the Reload() method provided by the datagrid to refresh the UI should now reflect the changes.
