Here is one article about how to implement DataGrid UI virtualization and data virtualization, you can take a look: For these reasons, it is desirable to use some sort of data virtualization mechanism to limit the amount of data objects that need to be retrieved and instantiated in memory. In addition, actually retrieving the data (e.g., from a database) and instantiating all the objects could be time consuming, particularly if a network operation Not significant however, for large collections, the memory consumption can become very significant. For relatively small collections of basic data objects, the memory consumption is Data virtualization is not provided by WPF. There is, however, a potentially large memory footprint due to the actual dataĭata virtualization is a term that means achieving virtualization for the actual data objects that are bound to the ItemsControl. UI virtualization means that controls can be bound to large collections without incurring a large memory footprint due to visual containers. When container recycling is enabled, it will reuse visual containers instead of creatingĪnd disposing, avoiding the object instantiation and garbage collection overheads. When the user scrolls, new visual containers are created as items become visible, and old containers are disposed when items are no longer visible. When a WPF ItemsControl is bound to a large collection data source, with UI virtualization enabled, the control will only create visual containers for the items that are actually visible (plus a few above and below). So I suggest that you not only use DataGrid UI virtualization, but also implement data virtualization. I have also tried implementing VirtualizingObservableCollection through a nuget, however I am unable to get the VirtualizingObservableCollection to update and show my data in the datagrid upon any other methods than a window load.Īccording to your description and your code, I see you have implemented DataGrid UI Virtualization, but you said that you have 100,1000 row of data, I think you load all 100,1000 row data, so the process memory adter creating and displaying the datagrid My Process memory after creating and displaying the datagrid is near 3GB as well. Any other suggestions on how to increase the speed of the loading of a DataGrid would help, Thank you very much. ![]() I am uncertain whether my cells require a VirtualizingStackPanel in order to increase the loading speed. ![]() Right now these are the few options I have enabled on my DataGrid associated with virtualization: I have read up on data virtualization to make the datagrid load and scroll smoother but my grid is still extremely slow and I would like to clarify what is what. In another observablecollection inside the observablecollection) Right now I'm working with around 100,000 rows of data within a datagrid all within 1 nested observablecollection (each cell has more info inside contained I'm still pretty new with WPF and MVVM and I want to ask a few questions about data virtualization. ![]()
