Thank you for using Syncfusion products.
We request you to trigger “CurrentRecordContextChange” event for Parent Grid alone. And this event will trigger for both parent and child grid when record selected in grid. Please check with the video from the following link:
Could you please try this and let us know if you have any other queries.
Thanks for your update.
For your requirement , CurrentRecord can get from CurrentRecordContextChange event using “e.Table.CurrentRecord”. Please refer to the following code snippets:
public void MasterGrid_CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e)
Record r = null;
if (e.Action == CurrentRecordAction.EnterRecordComplete && e.Record != null)
r = e.Table.CurrentRecord;
Please try this and let us know if you have any queries.
