Description
I need tips and best practices to optimize performance when using the TreeView 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 TreeView with large datasets?
- What are layout best practices for TreeView in .NET MAUI?
- Do images in TreeView affect performance?
Solution
To optimize the performance of the TreeView in .NET MAUI, follow these steps:
- Avoid Nesting in ScrollView or StackLayout
- Implement Load-Children-on-Demand
- Optimize Image Handling
Avoid Nesting in ScrollView or StackLayout
Position the TreeView 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 TreeDataGrid, DataGrid, CollectionView, RichTextEditor, or PDF Viewer controls in a ScrollView. These controls have internal scrolling.
Implement Load-Children-on-Demand
When operating with a huge amount of data, consider loading child items on demand approach. This approach minimizes the initial load time and memory consumption by only loading nodes as they are expanded.
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.
