asp.net mvc 4 - Razor, MVC4, @html.dropdownlistfor problems -

-

i'm trying create drop down list populates database. have:

public class employee     {         [key]         public int id { get; set; }         [required]         public string firstname { get; set; }         [required]         public string lastname { get; set; }         [required]         public string jobtitle { get; set; }     }      public class project     {         [key]         public int id { get; set; }         [required]         public string projectname { get; set; }         [required]         public string companyname { get; set; }     }      public class projecthour     {         [key]         public int id { get; set; }         [required]         public decimal hours { get; set; }         [required]         public datetime date { get; set; }         public virtual icollection<employee> employeeid { get; set; }         public virtual icollection<project> projectid { get; set; }     }

what want create form create new project hours associated project , employee. i'm trying use dropdownlists display employees , projects on create form. obviously, i'm new @ this, have far is:

[httppost]      public actionresult createprojecthour(projecthour newprojecthour)      {              using (var db = new timesheetcontext())              {                  ienumerable<selectlistitem> emp = db.employees                   .select(c => new selectlistitem                   {                       value = c.id.tostring(),                       text = c.lastname                   });                  viewbag.employeeid = emp;                   db.projecthours.add(newprojecthour);                  db.savechanges();              }               return redirecttoaction("projecthourlist");          }      }

and on form:

@model timesheetmvc.models.projecthour ... @html.dropdownlistfor(model => model.employeeid, (selectlist)viewbag.employeeid)

which apparently horribly wrong. appreciated...!

don't use same name employeeid. need 2 things create dropdown list in asp.net mvc: scalar property hold selected value , collection property contain possible values. since using viewbag (which totally recommend against) following:

viewbag.employees = emp;

and in view:

@html.dropdownlistfor(     model => model.employeeid,      (ienumerable<selectlistitem>)viewbag.employees )

but said not @ approach recommend. recommend using view models. define ienumerable<selectlistitem> property on view model:

public ienumerable<selectlistitem> employees { get; set; }

and in controller populate view model property , make view typed view model.

c# - Copy ObservableCollection to another ObservableCollection -

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...
