asp.net - Page OnLoad not fireing changing query string -
i have problem onload event not fireing when navigate page , change query string. if postback called, changing query string ones more onload gets called.
here how try. navigate page onload fires -> change query string page updates (all bound elements updated) onload not fire -> postback using button onload fires -> change query string onload fires.
i try explain in more detail.
the system has log in window when log in navigate other aspx page sending 2 query string messages last query string number (page.aspx?key=text82&key2=2010). when page first time pageload event gets called , fine, if in browser change key2 2011 , press enter pageload not called bound elements updated (grivview etc..). if postback using button pageload gets called. if change 2011 2010 , press enter pageload called.
i try firefox pageload called every time.
i tired write test website not same problem, found out in ie 8 changing query string same number , pressing enter pageload not called. doing in firefox makes postback fire. here test code
