i had no idea when and where it_________ (had happened / happened)

i hace no idea ______(whether/that) he will go to the cencert with us.
否定词 后面用that ,陈述词后面用whether 有没有这条规则

had happened,whether
不是否定词后面用that,也不是陈述词后面用whether
仔细看下,这里前面用的是have no idea 后面是will,时态上发现了什么没,如果后面过去时,前面就构成了同位语从句就用that,由于从句用了will,所以前面主句就要用whether 或者if

happened,whether
