reactjs - React - on outside click of component subtree -


i'm aware of several solutions detecting 'outside' clicks react component - i.e. use dom elements' .contains method see if event originated within dom tree - however, know of can detect such events 'outside' of actual component hierarchy? example, work portals above method not (since dom tree isn't representative of react tree).

edit: example:

<div>   <div onoutsideclick={handleoutsideclick}> // onoutsideclick implementation todo     <div>       <button /> // same dom tree, same component tree, detected not outside (ding)     </div>     <div>       <portal>         <button /> // not same dom tree, same component tree, detected outside (bzzt)       </portal>     </div>   </div>   <button /> // not same component tree, nor dom tree, detected outside (ding) </div>

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
