Gridview freezes when deleting several records

[Ambar Kulkarni]

I am using a GridView to display real-time data (syslog messages) and it works fine as long as I keep adding records. However when I try to remove old records, the GridView just freezes (stops responding). Is there a special way to delete records? Right now I have bounds the ItemsSource to an ObservableCollection and when the number of records in it reaches 10,000 I want to delete the first 100 records (i.e index 0 through 99). GridView seems to have no problem dealing with the 10,000 records but as soon as I delete even one record, it stops responding. I have already tried my own variation of your AddRangeObservableCollection (modified it to stop CollectionChanged notification, delete 100 records and then re-start the CollectioChanged notifications) but the GridView still stops responding after deletion. Please help.

Hi Ambar,

 Can you send us your application (via support ticket) where we can reproduce and debug this?

Vlad,

Do you need the source code or just a installable product?

Thanks

Hi,

 Small example application (with source code) where we can reproduce the scenario and these problems will do the work.

Vlad,

Actually upgrading to the latest Q3 release fixed the problem.

Thanks for your response.
