ListView load a lot of data

Hello Ward,

From the explanation it seems that the you are loading all the data at ones and thus the UI thread is blocked and the app hangs. You can load the data asynchronously and use the ListView load on demand feature. For more information and example of the feature please follow the link leading to our documentation: https://docs.telerik.com/devtools/maui/controls/listview/load-on-demand 

I recommend loading 50 items at a time.

Let me know if this works for you.

Regards,
Antoan
