how to delete parent and child tasks on one go

[service buzz]

Hello All,

I have a requirement , we are able to delete parent record  but respective tasks  are remaining orphaned.

How can we delete the child tasks along with parent cases.

Is it possible to do automatic deletion ??

or can  restrict the parent case before task getting deleted?that means the hr case can be deleted only when related task is deleted?

please suggest how can we proceed.

Thanks
