asp.net - MVC 5 Complex View Model binding is not working -

public class createprojemodel {     public proje proje { get; set; }     public list<geometrymodel> geometrylist { get; set; }     public createprojemodel()     {         proje = new proje();         geometrylist = new list<geometrymodel>();     } }  public class geometrymodel {     public list<pointmodel> pointlist { get; set; }      public geometrymodel()     {         pointlist = new list<pointmodel>();     } }  public class pointmodel {     public int x { get; set; }     public int y { get; set; } }  public class proje : entitybase {     public int firmaid { get; set; }     public int ilid { get; set; }     public int? ilceid { get; set; }     public int planturid { get; set; }     public int etudturid { get; set; }     public int etudamacid { get; set; }     public int dilimid { get; set; }     public string aciklama { get; set; }      public virtual firma firma { get; set; }     public virtual il il { get; set; }     public virtual ilce ilce { get; set; }     public virtual plantur plantur { get; set; }     public virtual etudtur etudtur { get; set; }     public virtual etudamac etudamac { get; set; }     public virtual dilim dilim { get; set; }  } 

i have complex model named createprojemodel. i'm using 'for' loop collection properties , binding below:

@html.textboxfor(m => m.geometrylist[i].pointlist[j].x) 

action below:

[httppost] public async task<actionresult> create(createprojemodel proje) {     //todo     return view(proje); } 

posted data below:

when comes action, geometrylist empty , proje's properties not set post values. doing wrong?

your problem createprojemodel model has property named proje, parameter of create() method named proje. need change method signature (say)

public async task<actionresult> create(createprojemodel model) 

where parameter name not same nae of 1 of properties
