SfKanban memory leak

A child window containing only SfKanban remains in memory after closing the window. In a simple test case setup, I have no event to be dereferenced.

What is the proper way of disposing SfKanban and can you please demonstrate it?

Thanks.

Hi SaiGanesh,

Thanks for the update. The dispose is working fine now with the latest version. However, if I have a custom CardTemplate, the dispose throws System.NullReferenceException: 'Object reference not set to an instance of an object.'

I have attached samples for both previous and latest versions of SfKanban. Please have a look.

Regards.
