c# - Asp.net Checkbox issues after postback -


this asp.net project c#

i have gridview has checkbox column. user selects row clicking appropriate checkbox. can act on row doing various things (mostly button clicks). problem having when user clicks button, gridview refreshed. of time consists of row being deleted. when user goes select checkbox (another row in gridview) act upon, can briefly see check box , checkbox unchecked or checkbox below 1 wanting select gets checked. when occurring, oncheckedchanged not fire. when refresh page, selecting , deselecting checkboxes works intended without issues whatsoever.

just few sidenotes:

  1. i doing row highlighting using javascript based upon checkbox selected. (i can provide code if needed)

  2. i ensuring 1 checkbox selected @ time using code below under checkchanged event:

    checkbox activecheckbox = sender checkbox;  foreach (gridviewrow rw in gridview1.rows) {     checkbox chkbx = (checkbox)rw.findcontrol("rowlevelcheckbox1");     if (chkbx != activecheckbox)     {         chkbx.checked = false;     }     else if (chkbx == activecheckbox && (chkbx.checked != false && activecheckbox.checked != false))     {         chkbx.checked = true;     } }

  3. i binding gridview in codebehind in page load within if (!ispostback)

  4. before ask, yes have set autopostback="true" on checkbox

when button clicked setting checkbox.checked = false, when debug , check checkboxes in gridview on page load, after code has been executed, still shows 1 checked.

why behavior happening?

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
