vb.net - ASP.NET Maintaining ViewState for controls inside a custom control template -


i have template property in control declared follows:

<templatecontainer(gettype(generictemplatecontainer)),     persistencemode(persistencemode.innerproperty),     templateinstance(templateinstance.single)> property customtemplate itemplate

in control's init event have following:

if me.customtemplate isnot nothing     dim templatecontainer new generictemplatecontainer     me.customtemplate.instantiatein(templatecontainer)      placeholder.controls.add(templatecontainer) end if

this allows me place controls in markup inside template, on post controls inside template not holding viewstate.

i have tried adding persistchildren(true) attribute customtemplate property cannot because it's not valid.

are putting values viewstate? understand, need that. either that, or re-bind data on every postback.

here's inside user controls. apologize being c# , not vb, don't know vb:

    public string text {             { return (string)viewstate["text"]; }             set { viewstate["text"] = value; }     }

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...
