Description
I need tips and best practices to optimize performance when using the DataGrid 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 DataGrid with large datasets?
- What are layout best practices for DataGrid in .NET MAUI?
- Do images in DataGrid affect performance?
Solution
To optimize the performance of the DataGrid in .NET MAUI, follow these steps:
- Avoid Nesting in ScrollView or StackLayout
- Minimize Use of Templates in Columns
- Implement Load-on-Demand or Paging
- Optimize Image Handling
Avoid Nesting in ScrollView or StackLayout
Position the DataGrid 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 controls with internal scrolling (e.g., TreeView, TreeDataGrid, CollectionView, RichTextEditor, PDF Viewer) inside another scrollable element.
Minimize Use of Templates in Columns
Using template columns or cell content/edit templates can degrade performance. Rendering additional UI elements in templates forces the DataGrid to recreate and render elements inside these templates.
Use built-in column types wherever possible. If custom rendering is required, use the cell renderer approach. This reduces the overhead caused by template re-rendering.
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
Columns with images can slow down scrolling due to repeated rendering of image elements. Implement caching strategies to optimize image loading. For more details, refer to this image loading tutorial.
