Parties in pride and prejudice novel-Q

Hello

I have some questions abour parties in this novel..

Am wondering how many parties are done in this novel?
Does Mr. Benet make one of these parties?

please don't forget to tell about the invitors because I think one of them the invitor is Charlot's father- right?

In which party does Mr.Darcy refuse to dance with Elezabeth? ( who is the invitor?)
In which party does Elezabeth refuse to dance with Mr. Darcey? ( who is the invitor?)

In which party they agreed to dance together! ( who is the invitor?)

I hope u can orgnize this misunderstood.
