asp.net mvc 3 - Setting a drop downlist to a specific value in MVC 3 Razor -

-

afternoon all.

i have drop down list in view

    <div class="editor-label">                     @html.labelfor(model => model.sitetypeid, "sitetype")                 </div>                 <div class="editor-field">                     @html.dropdownlist("sitetypeid", (ienumerable<selectlistitem>) viewbag.sitetypeid)                     @html.validationmessagefor(model => model.sitetypeid)                 </div>

with model looking so:

public class sitetype         {             [key]             public int sitetypeid { get; set; }             public string sitetypename { get; set; }         }

currently there 2 items in drop down:

1 (value) - foo (item)   2 (value) - bar (item)

which appears via controller la:

public actionresult details(guid id)     {         var model = model(id);          viewbag.sitetypeid = new selectlist(db.sitetypes, "sitetypeid", "sitetypename");         return view(model.details);     }

users update accordingly , stored in database.

i can value of drop down list database no problem, how got binding value list?

man feel simple asking :'(

any appreciated.

don't use same name viewbag parameter containing selectlist first argument of dropdownlist helper:

viewbag.sitetypes = new selectlist(db.sitetypes, "sitetypeid", "sitetypename");

and in view:

@html.dropdownlist("sitetypeid", (ienumerable<selectlistitem>)viewbag.sitetypes)

now inside post action when form submitted selected value passed parameter called sitetypeid.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
