Hi Brian,

Greetings from Syncfusion support

Based on your query you are using Virtualization feature in the Grid and like to refresh the data. Before we start providing solution on your query, we need some more information for our clarification. So kindly share the below details,

1)              Share your exact requirement and use case scenario with detailed description about at what scenario you like to refresh the data.

2)              Could you please confirm you are performing any specific action in the Grid and after that you like to refresh data. If yes, kindly share the scenario step by step with detailed description.

3)              Share your complete Grid rendering code (Ts and Html code), so that we can review your initialization settings, implement features, event handling and data bindings. So based on that we can suggest the way to refresh the data without affecting other functionalities.

4)              Share your Syncfusion package version.

1. I have a dropdown list that changes the data via async call to a remote service (same columns different data

I was occasionally getting weird rendering issues in the grid (white space, sometimes when scrolling the rows would not render and would hang on the row refreshing view)

After reading the documentation I found the method changeDataSource which seemed to resolve the issues I was having when updating the datasource.
