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?

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() .
