Greeting from Syncfusion,
Query: Why the Sparkline template value is destroyed while sort any other columns?
As per your query, the sparkline template data is bounded in the created event which is triggered for EJ2 Grid initial rendering alone. Since, we suspect that the sparkline data is not re-rendered after sorting the EJ2 Grid, We suggest you to use dataBound event instead of created event to achieve your requirement which is trigger for every EJ2 Grid action. Please refer the following Documentation for more information.
