Description
I need tips and best practices to optimize performance when using the CollectionView control with thousands of data entries. I want to know how layouts wrapping the control affect performance and whether images reduce performance.
This knowledge base article also answers the following questions:
- How to optimize performance for CollectionView with large datasets?
- What are layout best practices for CollectionView in .NET MAUI?
- Do images in CollectionView affect performance?
Solution
To optimize the performance of the CollectionView in .NET MAUI, follow these steps:
- Avoid Nesting in ScrollView or StackLayout
- Implement Load-on-Demand or Paging
- Optimize Image Handling
Avoid Nesting in ScrollView or StackLayout
Position the CollectionView inside a Grid with a * row height. Avoid nesting the control inside Stack or ScrollView. Nesting scrollable objects breaks UI virtualization and can impact performance. Refer to Microsoft documentation for details on scrollable objects.
Avoid wrapping Telerik MAUI TreeView, DataGrid, TreeDataGrid, RichTextEditor, or PDF Viewer controls in a ScrollView. These controls have internal scrolling.
Implement Load-on-Demand or Paging
Load large datasets incrementally using the LoadOnDemand feature or divide them into manageable chunks with the Paging feature.
Optimize Image Handling
When working with images, implementing caching strategies is a way to optimize the image loading process. For more details, refer to this image loading tutorial.
