Upgraded from .Netframework 3.5 to 4.8 and tested with existing Telerik version 2015.3.1111.35 in Microsoft Edge Browser.
Microsoft Edge Browser Version -90.0.818.46 (64-bit)(Chromium) .
1.Replicating by sorting on the Date, source, Name as shown in Screenshot 1 .
2.Observed the issue RadGridNamespace.RadGrid.AsyncRequest.
3.So,we have tried with telerik control to R3 2020.3.915.45 and .Netframework is same as 4.8 -but still issue exists with upgraded Telerik R32020 as well.
Can anyone please help on the issue?
