Now, I'm annoyed.
I've never been overly fond of the whole Crystal Reports/MS Reporting control schemes. It's more of the fact that I just don't like reporting than anything inherently wrong with those controls.
Yet, I'm now true and peeved concerning RDLC.
Backstory: I'm building this report, which displays 3 levels of the application's hierarchy at a time, and that bottom level is responsible for doing the drill through effect. Well, going from step 1 to step 2 worked perfectly fine. But stepping from 2 to 3 just cause a postback and redisplaying 2 on the first click. On the second click, the step 3 portion of the report displays correctly. Additional playing about with the EVENT HANDLERS show that this behavior occurs regardless of which event is being fired (though some events still process).
So, now that that huge blurb of backstory is done, I'm still stuck here trying my darnedest to figure out just what is going on.
