c# - how do i select value from dropdownlist to mode or to controller mvc -


model

public class company {     public int id { get; set; }     ....     public int workzoneid { get; set;  }     public ienumerable<selectlistitem> workzones { get; set; }

controller:

viewbag.workzones = cmprep.getworkzonedrop();

repository:

public list<selectlistitem> getworkzonedrop() {     sqldatareader dr;     dr = ado.execdatareaderproc("workzoneselectactive");     list<selectlistitem> selectworkzonelistitems = new     list<selectlistitem>();     companyvmlist c = new companyvmlist();     c.companies = new list<company>();     while (dr.read())     {         selectlistitem selectlistitem = new selectlistitem         {             text = convert.tostring(dr["name"]),             value = convert.tostring(dr["id"]),         };         selectworkzonelistitems.add(selectlistitem);     }     return selectworkzonelistitems; }

view

@html.dropdownlist("workzones")

i want assign selected dropdownlist value int work zone int mode how select value dropdownlist model or controller

you need bind dropdownlist property workzoneid

@html.dropdownlistfor(m => m.workzoneid, model.workzones)

and if wanting preselect option, need set value in controller before pass model view. , since model contains property selectlist, use (don't use viewbag)

company model = new company {     workzoneid = 1 // set value matches 1 of options     workzones = cmprep.getworkzonedrop(); }; return view(model);

and when submit to

[httppost] public actionresult edit(company model)

the value of model.workzoneid contain value of selected option.

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). ...
