c# - ActionLink with multiple parameters doesnt work -


my routing looks this:

routes.maproute(                 name: "default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "home", action = "index", id = urlparameter.optional }             );

this link after clicking should redirect appropriate id action index. action index located in controller: kursymanage.

columns.add()                .encoded(false)                .sanitized(false)                .setwidth(10)                        //text     //action //controller                 .rendervalueas(c => html.actionlink("zarzadzaj", "index", "kursymanage", new { id = c.id }, null));

unfortunately, action index gets empty value (null). in case when not use name of controller, works fine.

 public actionresult index(int? pidkursu)             {                 var schemalist = (from scheme in szkolajezykowadb.kursyusers scheme.kursid == pidkursu && scheme.czyzapisany == 0 select scheme).tolist();                 return view(schemalist);             }

could please advice me made mistake?

change name of parameter in index method match value setting in view.

 public actionresult index(int? id)         {             var schemalist = (from scheme in szkolajezykowadb.kursyusers scheme.kursid == id && scheme.czyzapisany == 0 select scheme).tolist();             return view(schemalist);         }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

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() .
