i new mvc , have question have page (asp.net mvc 3) called profile contains 3 partial view called (1) address,qualification,experience. each of partial view should allow add details , save details/contents without affecting others. how can attach action each partial view save button , postback result without refreshing other partial view. can explain me , without using jquery/ajax without ajax or jquery you'd stuck doing horrible iframes... stick jquery, best , easiest way. actually, here 1 way might able it. name "submit" buttons according method want called. then, have of 3 sets of data inputs within 1 <form></form> posts intermediate controller endpoint. in intermediate controller endpoint, determine button pressed, pass correct data normal control methods, , push other data view. way can fill out inputs, click appropriate submit button, correct data gets used! other data gets pushed view , approprate input boxes filled out.

i have 2 classes, 1 make frame , other handle , implement interface tablemodel. when editing cells inline , updating values in class implements tablemodel need refresh table show updated data (as table needs auto sort when inline edit cell rows may need re-ordered). problem i'm having after updating data can't figure out how refresh table, i've tried hacky way of refreshing when click off cell or press enter feel there more elegant solution, ideas? the tablemodel responsible invoking firetablecellchanged(...) method when data changed in model. sorting happen automatically. read jtable api , follow link swing tutorial on how use tables more information tablemodels , sorting. i suggest use defaulttablemodel don't have worry since implements tablemodel methods.

is bad practice use use foreach make array of post data vs defining posts accepting? class foo { function __construct() { foreach($_post $key => $var) { $this->post[] = $key = $var; } } function bar() { echo $this->post['postdata']; } } vs; class foo { function __construct() { $this->post = array( "postdata" => $_post['postdata'] ); } function bar() { echo $this->post['postdata']; } } there no great harm in automatically processing of posted fields, long processing limited storing in hash. matter of fact, can make fore easier maintain code. the moment start doing (especially system related) data, need validate.

i made handwritten slides using ipad app, , found out line thin projected on big screen in room. unfortunately app doesn't have ability change stroke widths afterwards...

i have page 6 textboxes, if enter values in text boxes , refresh page - values jump next text box (actually 2nd next text box). so if have entered values following [1] [2] [3] [4] [5] [6] after refresh becomes: [0] [0] [1] [2] [3] [4] on next refresh values shifted 2 text boxes again. text boxes created with: <input type='text' id='foo' class='bar' value='0'/> i think important use flexbox jquery plugin replaces given element two new input elements. removing flexbox solve issue. you can try out here enter values in "stat weights" row @ bottom of big table, after hitting f5 value jump have described. browser: firefox questions: 1) how fix this? 2) normal behavior browser try put entered value after refresh? or have rogue code somewhere doing that? untested: give inputs unique name values.
