Fast way to insert rows from Thread

[LindenauAtSOG]

Lets say we have a program that can search files for specific content and then display searchresults in a RadGridView.

The program uses multiple threads to search through those files.

Our problem here is, that when those threads get many search results the Dispatcher will be flooded with Add-Operations.
This causes massive ui-freezes.

My first approach to solve this issue was to "buffer" those searchresults and only invoke Add-Operations every second.
This is better but still freezing the ui.

So my question here is, is there a recommended way to setup a DataSource for RadGridView for this usecase?
Do I need to do stuff with CollectionViewSource?

Rightnow, we are using

ObservableCollection<T>

 with  

BindingOperations.EnableCollectionSynchronization.

Hello,

Speaking generally, if there are a lot of notifications for the UI to be updated it is possible that the WPF framework might not be able to handle them. With this in mind, I can suggest checking out the RadObservableCollection. It allows you to suspend the UI notifications for some time and resume them afterwards. 

That said, making sure that there is a larger amount of time between performing the add operations should also increase the responsiveness.

I hope you find this helpful. Don't hesitate to contact us again, if you have any other questions or concerns.
