Rapid updates on DataGrid does not work past version 20.1.0.48

Question

Hello,I have a project that is frequently updating the underlying data source of a DataGrid. When running version 20.1.0.48 the grid behaves well with frequent updates. However when updating to any newer version the grid becomes unusable with frequent updates due to the loading/rendering time of the component. Further, when upgrading to recent versions, any expanded rows with a Detail Template are collapsed when the data updated and component rendered.To reproduce this see attached project. Run with version 20.1.0.48 and the grid is very usable when updating the underlying data every 10ms. Then upgrade to latest version 20.3.0.47 and run. To see the issue with the expanded rows collapsing on data changes run version 20.3.0.47 and change the timer callback period from 10ms to 1000ms, run the project and expand a detail template. How do I achieve a grid that is functional with frequent updates after version 20.1.0.48?Thank you,Attachment: DemoApplication_dd8068f1.zip
