F%#@ yes! Got it figured out from some code Matt Faus posted about adding a confirmation to a submit button, not sure why I didn't find it before. Anyway, here it is in case anyone else wants to know.
var response = XDocument.UI.Confirm("Do you really want to delete?",4);
if(response == 6)
{
var thisNode = eventObj.Source.selectSingleNode(".");
thisNode.parentNode.removeChild(thisNode);
}
else
{
return;
Cheers for all your help, I hope this is the last time I'll have to do this!
