I have a product which has viewModel:
ProductViewModel
private int _id;
private string _name;
private string _type;
private int _selectedID;
public ProductViewModel(int id, string name, string type)
{
_ id = id;
_ name = name;
_ type = type;
}
public int ProductID
{
get { return _id; }
set { _id = value; }
}
public string Name
{
get { return _name; }
set { _name = value; }
}
public string Type
{
get { return _type; }
set { _type = value; }
}
public int Selected
{
get { return _selected; }
set { _selected = value; }
}
And for showing a list of products I have another ViewModel:
ProductListViewModel
private PagedResult<ProductViewModel> _pagedResult;
private string _sortColumn = "Id";
private string _sortOrder = "ASC";
public LostAssetsListViewModel(PagedResult< ProductViewModel > products)
{
_pagedResult = products;
}
public PagedResult<ProductViewModel> List
{
get { return _pagedResult; }
set { _pagedResult = value; }
}
public string SortColumn
{
get { return _sortColumn; }
set { _sortColumn = value; }
}
public string SortOrder
{
get { return _sortOrder; }
set { _sortOrder = value; }
}
And in my View I'm using Product LisViewModel to show a list of products. And in every product I want to add radio button (to select that product)
<% = Html.RadioButtonFor(m => m.List[i].Selected, "false", Model.List[i]. ProductID)%>
For getting all the data in my controller I created ProductInputModel:
ProductInputModel
private int _id;
private string _name;
private string _type;
private int _selectedID;
public ProductInputModel(int id, string name, string type)
{
_ id = id;
_ name = name;
_ type = type;
}
public int ProductID
{
get { return _id; }
set { _id = value; }
}
public string Name
{
get { return _name; }
set { _name = value; }
}
public string Type
{
get { return _type; }
set { _type = value; }
}
public int Selected
{
get { return _selected; }
set { _selected = value; }
}
In my controller input is empty :
[HttpPost]
public ActionResult Details(ProductInputModel input)
{}
I can't figure out whydata from ProductViewModel not passes to ProductInputModel. How I should get the selected product through ViewModels?
Your view models must have default parameterless constructors if you want to use them as action parameters. Otherwise the default model binder will not be able to instantiate it. You should make sure that you have a parameterless constructor to your ProductInputModel.

Is there a way to map database fields to OOP complex type fields with Enterprise Library. I am calling stored procedures that retrieves all data that I would like to store into custom class.
Here I retrieve data from sp:
IEnumerable<WorkHistoryGrid> data = new List<WorkHistoryGrid>();
return db.ExecuteSprocAccessor<WorkHistoryGrid>("PensionPDF_RetrieveParticipantWorkHistoryForFund", pensionId, fund);
And here is my class
public class WorkHistoryGrid : BindableBase
{
private string _rateType;
private string _fundType;
private string _employer;
private string _employerName;
private string _local;
private string _dateBalanced;
private string _plan;
private string _fund;
private WorkHistoryGridMergeData _mergeData;
#region Properties
public WorkHistoryGridMergeData MergeData
{
get { return _mergeData; }
set { SetProperty(ref _mergeData, value); }
}
public string RateType
{
get { return _rateType; }
set { SetProperty(ref _rateType, value); }
}
public string FundType
{
get { return _fundType; }
set { SetProperty(ref _fundType, value); }
}
public string Employer
{
get { return _employer; }
set { SetProperty(ref _employer, value); }
}
public string EmployerName
{
get { return _employerName; }
set { SetProperty(ref _employerName, value); }
}
public string Local
{
get { return _local; }
set { SetProperty(ref _local, value); }
}
public string DateBalanced
{
get { return _dateBalanced; }
set { SetProperty(ref _dateBalanced, value); }
}
public string Plan
{
get { return _plan; }
set { SetProperty(ref _plan, value); }
}
public string Fund
{
get { return _fund; }
set { SetProperty(ref _fund, value); }
}
}
}
}
It works fine if I would create one class with all database fields, but I would like to have more control over it by mapping database fields to custom complex type properties.
Here is the answer in my case, in case someone would look for similar solution:
var workHistoryGridSetMapper = new WorkHistoryGridSetMapper();
db.ExecuteSprocAccessor<WorkHistoryGrid>("PensionPDF_RetrieveParticipantWorkHistory", workHistoryGridSetMapper, pensionId);
IResultSetMapper
public class WorkHistoryGridSetMapper : IResultSetMapper<WorkHistoryGrid>
{
public IEnumerable<WorkHistoryGrid> MapSet(IDataReader reader)
{
List<WorkHistoryGrid> workHistoryLst = new List<WorkHistoryGrid>();
using (reader) // Dispose the reader when we're done
{
while (reader.Read())
{
WorkHistoryGrid workHist = new WorkHistoryGrid();
workHist.Amount = reader.GetValue(reader.GetOrdinal("Amount")).ToString();
workHist.DateBalanced = reader.GetValue(reader.GetOrdinal("DateBalanced")).ToString();
workHist.Employer = reader.GetValue(reader.GetOrdinal("Employer")).ToString();
workHist.EmployerName = reader.GetValue(reader.GetOrdinal("EmployerName")).ToString();
workHist.Fund = reader.GetValue(reader.GetOrdinal("Fund")).ToString();
workHist.FundType = reader.GetValue(reader.GetOrdinal("FundType")).ToString();
workHist.Hours = reader.GetValue(reader.GetOrdinal("Hours")).ToString();
workHist.Local = reader.GetValue(reader.GetOrdinal("Local")).ToString();
workHist.Period = reader.GetValue(reader.GetOrdinal("Period")).ToString();
workHist.Plan = reader.GetValue(reader.GetOrdinal("Plan")).ToString();
workHist.RateAmount = reader.GetValue(reader.GetOrdinal("RateAmount")).ToString();
workHist.RateType = reader.GetValue(reader.GetOrdinal("RateType")).ToString();
workHist.Status = reader.GetValue(reader.GetOrdinal("Status")).ToString();
workHist.WorkMonth = reader.GetValue(reader.GetOrdinal("WorkMonth")).ToString();
workHist.MergeData = new WorkHistoryGridMergeData
{
MergeDateMerged = reader.GetValue(reader.GetOrdinal("MergeDateMerged")).ToString(),
MergeLastUpdated = reader.GetValue(reader.GetOrdinal("MergeLastUpdated")).ToString(),
MergeLastUpdatedUserId = reader.GetValue(reader.GetOrdinal("MergeLastUpdatedUserId")).ToString(),
MergeLastUpdatedUserType = reader.GetValue(reader.GetOrdinal("MergeLastUpdatedUserType")).ToString(),
MergeNewSsn = reader.GetValue(reader.GetOrdinal("MergeNewSsn")).ToString(),
MergeNotes = reader.GetValue(reader.GetOrdinal("MergeNotes")).ToString(),
MergeOldSsn = reader.GetValue(reader.GetOrdinal("MergeOldSsn")).ToString(),
MergeTrustId = reader.GetValue(reader.GetOrdinal("MergeTrustId")).ToString(),
MergeUserName = reader.GetValue(reader.GetOrdinal("MergeUserName")).ToString()
};
workHistoryLst.Add(workHist);
};
}
return workHistoryLst;
}
}
I have below class:
namespace ESF.Engine.SharedObjects.CatalogManagement
{
[DataContract()]
public class Customer
{
private string _LastName;
private System.DateTime _BirthDate;
private decimal _MoneyInCash;
private bool _IsActive;
private string _AdditionalInfo;
private decimal _ITEMID;
private string _NAME;
[DataMember()]
public string LastName
{
get
{
return this._LastName;
}
set
{
this._LastName = value;
}
}
[DataMember()]
public System.DateTime BirthDate
{
get
{
return this._BirthDate;
}
set
{
this._BirthDate = value;
}
}
[DataMember()]
public decimal MoneyInCash
{
get
{
return this._MoneyInCash;
}
set
{
this._MoneyInCash = value;
}
}
[DataMember()]
public bool IsActive
{
get
{
return this._IsActive;
}
set
{
this._IsActive = value;
}
}
[DataMember()]
public string AdditionalInfo
{
get
{
return this._AdditionalInfo;
}
set
{
this._AdditionalInfo = value;
}
}
[DataMember()]
public decimal ITEMID
{
get
{
return this._ITEMID;
}
set
{
this._ITEMID = value;
}
}
[DataMember()]
public string NAME
{
get
{
return this._NAME;
}
set
{
this._NAME = value;
}
}
}
}
After adding Service Reference, the proxy for this class generated under namespace which is default for client application.
Is it possible to force the class proxy to be generated as it is in server?
Thanks for your time.
This is my model structure from which I want to use to create a treeview, with checkboxes on leaf nodes:
public class CategoryEntity : BaseEntity
{
public CategoryEntity()
: base()
{
}
private Guid _categoryId;
public Guid CategoryId
{
get { return _categoryId; }
set { _categoryId = value; InvokePropertyChanged("CategoryId"); IsDirty = true; }
}
private string _categoryname;
public string CategoryName
{
get { return _categoryname; }
set { _categoryname = value; InvokePropertyChanged("CategoryName"); IsDirty = true; }
}
private string _categorydescription;
public string CategoryDescription
{
get { return _categorydescription; }
set { _categorydescription = value; InvokePropertyChanged("CategoryDescription"); IsDirty = true; }
}
private string _categorytype;
public string CategoryType
{
get { return _categorytype; }
set { _categorytype = value; InvokePropertyChanged("CategoryType"); IsDirty = true; }
}
private Guid? _parentcategoryId;
public Guid? ParentCategoryId
{
get { return _parentcategoryId; }
set { _parentcategoryId = value; InvokePropertyChanged("ParentCategoryId"); IsDirty = true; }
}
}
The problem is that I am new to MVC and I don't know which controls to use to display this values in a tree structure. Can anyone suggest a way of doing this?
I am using Telerik's WPF controls with Caliburn.Micro. In particular the DataForm control. I am trying to bind it to an object that has the following make up.
public class FrequencyMap : BindableBase
{
private Guid id;
public Guid ID
{
get { return id; }
set
{
id = value;
OnPropertyChanged();
}
}
private string procedureCodeId;
public string ProcedureCodeId
{
get { return procedureCodeId; }
set
{
procedureCodeId = value;
OnPropertyChanged();
}
}
private FrequencyChoice frequency;
public FrequencyChoice Frequency
{
get { return frequency; }
set
{
frequency = value;
OnPropertyChanged();
}
}
private DateTime effectiveDate;
public DateTime EffectiveDate
{
get { return effectiveDate; }
set
{
effectiveDate = value;
OnPropertyChanged();
}
}
private DateTime? terminateDate;
public DateTime? TerminateDate
{
get { return terminateDate; }
set
{
terminateDate = value;
OnPropertyChanged();
}
}
}
and then the FrequencyChoice object looks like this:
public class FrequencyChoice : BindableBase
{
private int id;
private string modifiedUser;
public int ID
{
get { return id; }
set
{
id = value; OnPropertyChanged();
}
}
private string code;
public string Code
{
get { return code; }
set
{
code = value; OnPropertyChanged();
}
}
private string name;
public string Name
{
get { return name; }
set
{
name = value; OnPropertyChanged();
}
}
private string description;
public string Description
{
get { return description; }
set
{
description = value; OnPropertyChanged();
}
}
private string calculationDescription;
public string CalculationDescription
{
get { return calculationDescription; }
set
{
calculationDescription = value; OnPropertyChanged();
}
}
private DateTime inactiveDate;
public DateTime InactiveDate
{
get { return inactiveDate; }
set
{
inactiveDate = value; OnPropertyChanged();
}
}
public string ModifiedUser
{
get
{
return this.modifiedUser;
}
set
{
this.modifiedUser = value;
OnPropertyChanged();
}
}
}
This works quite well except for the Frequency property. How do I get that to work properly. Do I have to use an Enum like this article? Data Forms in your XAML
If so how would I link the two?
I guess what you want is 1 Frequency Map with Many FrequencyChoices relationship
1st I would change the property to inherit from PropertyChangedBase
public class FrequencyChoice : PropertyChangedBase
{
}
then change your properties as below
private BindableCollection<FrequencyChoice> frequencyChoices;
public BindableCollection<FrequencyChoice> FrequencyChoices
{
get
{
return this.frequencyChoices;
}
set
{
if (Equals(value, this.frequencyChoices))
{
return;
}
this.frequencyChoices = value;
this.NotifyOfPropertyChange(() => this.FrequencyChoices);
}
}
I am not really sure what is BindableBase (from google is Prism but hey ur using Caliburn so use PropertyChangedBase) but if want to still use it go ahead but just make sure it handle change notification for you
as each map has many choices you will need collection to store the choices
[ActiveRecord]
public class Category
{
private int _id;
private string _name;
private Category _category;
[PrimaryKey(PrimaryKeyType.HiLo, "id", Params = "max_lo=9")]
public long Id
{
get { return _id; }
protected internal set { _id = value; }
}
[Property]
public string Name
{
get { return _name; }
set { _name = value; }
}
[BelongsTo("ParentCategoryId")]
public Category ParentCategory
{
get { return _category;}
set { _category = value; }
}
}
Table is correctly generated in the database and data can be insterted without any problems
But when I'm running
var criteria = DetachedCriteria.For<Category>
.Add(Restrictions.Eq("ParentCategory.ParentCategoryId", testCategory.id));
Assert.That(m_repository.FindAll(criteria).Length, Is.EqualTo(1));
I'm reciving QueryException
`NHibernate.QueryException : could not
resolve property:
ParentCategory.ParentCategoryId'
Any idea?
You are fetching the ParentCategory property of a Category, which is itself a Category. Your DetachedCriteria should be:
var criteria = DetachedCriteria.For<Category>()
.Add(Restrictions.Eq("ParentCategory.Id",
testCategory.id));
