I don't know about SPServices, but here is the method I am using to delete a record from a list.
function DeleteRecordFromList(listName,recordId){
$.ajax({
url: '/_vti_bin/listdata.svc/'+listName+'('+recordId+')',
type: "DELETE",
contentType: "application/json; charset=utf-8",
success: function () {
alert("Record has been deleted");
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status + " " + thrownError);
}
});
}
Be careful, the list name is case sensitive! If you want to do it from C#, you have instantiate an HttpRequest and call the same url as in the ajax call above. But if you are already in C#, why not just use the Object Model? Why to use jQuery? More about listdata.svc: http://msdn.microsoft.com/en-us/library/ff798339.aspx
I hope it helped!

1Well, you could use a global javascript variable like: var ID = '<%= IdPropertyFromCodeBehind%>'; See [this] (sharepoint.stackexchange.com/questions/52713/…) post too, maybe.Norbert– Norbert2012-11-29 14:31:22 +00:00Commented Nov 29, 2012 at 14:31

1Ok, so if I understood you correctly: you want to cascade delete items from the SecondList when you delete an item from the First list. In this case, please consider adding an extra column to the SecondList to hold the ID of the "parent" from the FirstList. Add an EventReceiver on ItemDeleting on the FirstList, and delete all items also from SecondList where secondListItem["ParentId"] == idBeingDeleted.Norbert– Norbert2012-11-29 15:48:32 +00:00Commented Nov 29, 2012 at 15:48
I am not repeating the steps for jQuery as it's already described by @Norbert, but you can have a look at this post for C# way
