GridView: Degraded performance when replacing column groups during runtime
Clearing and updating the ColumnGroups collection results in degraded performance when there is a big amount of column groups.
Posted on:16 Oct 2020 12:56
The ColumnGroups property is now of type RadObservableCollection which exposes an AddRange method which should be used when adding multiple groups at once to avoid performance issues. An alternative is to use the SuspendNotifications and ResumeNotifications methods prior and after adding the groups.
