c# - Passing Parameter From Main to Detail in MVVMCross -

i trying pass selected item list detail view, myitem null in detailviewmodel though not in myviewmodel.

myviewmodel.cs

    public virtual icommand itemselected     {                 {             return new mvxcommand<myviewmodel>(item =>{selecteditem = item;});         }      }      public myviewmodel selecteditem     {         { return _selecteditem; }         set         {             _selecteditem = value;             // myitem not null here!!!             showviewmodel<mydetailviewmodel>(new { date = date, myitem = _selecteditem });             raisepropertychanged(() => selecteditem);         }     } 

mydetailviewmodel.cs

public class  mydetailviewmodel: mvxviewmodel {     private myviewmodel _myitem;      public void init(datetime date, myviewmodel myitem = null)     {         // myitem null here!!!         _myitem = myitem;     } } 

you can use parameter object, because can pass 1 parameter. crate nested class parameter this.

public class  mydetailviewmodel: mvxviewmodel {     private myviewmodel _myitem;      public class parameter     {         public datetime date {get; set; }         public string name {get; set;}     }      public void init(parameter param)     {         name = param.name;     } } 

and show viewmodel like:

showviewmodel<mydetailviewmodel>(new mydetailviewmodel.parameter { date = date, name = _selecteditem.name }); 

but aware!

the paramters cannot complex due platform issues. might have pass id of item within parameter object , load myitem in init function. or pass string , use serialization: https://stackoverflow.com/a/19059938/1489968
