DeleteRecord performance

[Administrator]

I am using a GridGroupingControl.Table (version 4.2) and C#. We have a performance problem when deleting a large amount of records with the following code:

foreach (SelectedRecord r in Table.SelectedRecords)
{
Table.DeleteRecord(r.Record);
}

This can take several hours for 50000 records. Is there a more effective way to delete a large amount of records?

Hi Kazuaki,

Thanks for your interest in Syncfusion products.

To get better performance in deleting records, please refer to the GroupingPerf browser sample in the following location
[LocalDrive]:\\Syncfusion\EssentialStudio\[version]\Windows\Grid.Grouping.Windows\Samples\2.0\PerformanceSamples\GroupingPerf

In this sample, the memory usage log is shown which illustrates how faster the records are getting deleted.

Please let me know if you have any further concerns.

Regards,
Rajadurai
