c# - Page.Title set in child's Page_Init empty in parent's Page_PreRender -


there 2 files involved:

  • childpage.aspx.cs class childpage : parentpage
  • parentpage.cs class parentpage : system.web.ui.page

childpage.aspx.cs has method

protected page_init(object sender, eventargs e)  {     page.title = "abc"; }

parentpage.cs has property , method

public string mymodifiedtitle  {         {         // adding 123 super important.         return page.title + "123";     } }  protected override void onprerender(eventargs e) {     base.onprerender(e);      // add open graph meta tag modified title.     htmlmeta tag = new htmlmeta();     tag.attributes.add("property", "og:title");     tag.content = mymodifiedtitle;     header.controls.add(tag); }

page.title set "abc", og:title meta tag set "123" instead of "abc123".

why page.title cleared out before onprerender?

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
