getSelectedRecords() is empty on rowSelected when virtualization is enabled and records grouped

[Paolo Turello]

Hello, we are using grid with very large dataset so we have enabled virtualization option and we use grid.getSelectedRecrods() on selection and deselection to known selected records.

Everything works fine until the user groups records by column(s), when records are grouped the  grid.getSelectedRecrods() returns empty array even if rows are selected.

I attached a sample app with a subset of 4 records reproducing that issue, every suggestions are appreciated.

Thanks in advance.

Hi Paolo Turello,

 

We are glad to announce that, we have included the fix for the issue “grid.getSelectedRecords() Returns Empty Array for Selected Rows in Virtualization enabled Grid with Grouping” in our 29.1.37 release. So please upgrade to our latest version of the Syncfusion package to resolve the reported issue.

 

Root Cause: The issue occurred because the condition was triggered twice when the dataSource had fewer records than required to fill a block, causing duplicate calls to getGroupVirtualRecordsByIndex.

 

Fix: The condition was updated to proceed only when the cache is empty, preventing duplicate method calls and ensuring correct record retrieval.
