i htmlcontrols because there no html magic going on... asp source looks similar client sees. i can't argue utility of gridview, repeater, checkboxlists, etc, use them when need functionality. also, looks weird have code mixes , matches: <asp:button id='btnok' runat='server' text='ok' /> <input id='btncancel' runat='server' type='button' value='cancel' /> (the above case in event wanted bind server-side event listener ok cancel runs javascript hides current div) is there definitive style guide out there? should htmlcontrols avoided? it might useful think of html controls option when want more control on mark ends getting emitted page. more control in sense want every browser see same markup. if create system.web.ui.htmlcontrols like: <input id='btncancel' runat='server' type='button' value='cancel' /> then know kind of code going emitted. though of t...

i have inherited medium sized rails application , want try optimize right away. want start database ensure indexes placed need forth. therefore need find out possible sql statements activerecord might make can compare database schema , see immediate optimization can made. in short: there equivalent rake routes output possible sql templates? the hard way the rails development log file should contain of sql used during execution of server. grep file select statements - perhaps getting little smarter using regexp. unfortunately you're unlikely ever able process of information therein manage exception a better way use simple monitoring solution alert when request runs (e.g. scout ). @ rails log file see if problem related db. use db tools most dbs alert via log file somewhere if query runs - mysql example has 'slow queries log'.
