Performance issue while converting the datatemplate into view #17572

Open saiganesh-sakthivel opened 1 year ago

saiganesh-sakthivel commented 1 year ago

Description

In our custom control, we convert the DataTemplate into a view and add it to the UI. However, we have noticed that the conversion of complex DataTemplates takes more time to render the UI compared to simple ones on Windows and MacOS. In Android and iOS the performance remains high regardless of whether the DataTemplate is simple or complex. We achieve this by utilizing the CreateContent() method for template conversion.

Steps to Reproduce

  1. Run the Sample.
  2. Click the button in the view.
  3. It took more time to render the UI (which a custom view data template)

This issue is in the backlog milestone. It basically means that nobody is assigned to work on this and there is no progress (AFAIK). Issues that are currently being worked on are here https://github.com/orgs/dotnet/projects/194/views/39.

If anyone is willing to spend more time on this, then https://github.com/dotnet/maui/wiki/Profiling-.NET-MAUI-Apps#windows--dotnet-trace is a good place to learn how to create a speedscope which might shed more light on what exactly is the main contributor to the slowness here.
