c# - Query inside a thread -

-

i have 3 comboboxes loaded data linq queries on page load. problem queries contain data causes internet explorer stop responding bit more minute.

as there 3 queries idea put them in 3 different threads, problem @ end thing error saying: "both datasource , datasourceid defined on 'cborganizator'. remove 1 definition."

cborganizator combobox.

here code:

protected void page_load(object sender, eventargs e) {     bind(); }  public void osobe()     {         pravosudnaakademijaentities db = new pravosudnaakademijaentities();          var osoba = o in db.osobas                     orderby o.osoba_prezime                     select new { o.osoba_id, imeprezime = o.osoba_prezime + " " + o.osoba_ime + " | " + o.tijelo.tijelo_naziv + " | " + o.radno_mjesto.rm_naziv_m };          cbpolaznik.datasource = osoba;         cbpolaznik.datatextfield = "imeprezime";         cbpolaznik.datavaluefield = "osoba_id";         cbpolaznik.databind();         cbpolaznik.items.insert(0, " ");          cbpredavac.datasource = osoba;         cbpredavac.datatextfield = "imeprezime";         cbpredavac.datavaluefield = "osoba_id";         cbpredavac.databind();         cbpredavac.items.insert(0, " ");          cbaom.datasource = osoba;         cbaom.datatextfield = "imeprezime";         cbaom.datavaluefield = "osoba_id";         cbaom.databind();         cbaom.items.insert(0, " ");     }      public void tijela()     {         pravosudnaakademijaentities db = new pravosudnaakademijaentities();          var tijelo = t in db.tijeloes                      orderby t.tijelo_naziv                      select new { t.tijelo_id, sve = t.tijelo_naziv + " | " + t.mjesto.zupanija_drzava.zupanija_naziv };          cborganizator.datasource = tijelo;         cborganizator.datatextfield = "sve";         cborganizator.datavaluefield = "tijelo_id";         cborganizator.databind();         cborganizator.items.insert(0, " ");     }      public void bind()     {          thread tosobe = new thread(osobe);          tosobe.start();          thread ttijela = new thread(tijela);          ttijela.start();     }

i don't know what's wrong appreciated. primary idea separate queries threads if approach wrong please let me know.

you're starting threads not giving them chance finish before page loaded. don't know how results in particular error, if page loads before thread completed, won't results.

i don't see how you'll able accomplish you're trying without ajax.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
