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

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 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.
I have a class, with a public property "appController", as follows:
public class FAST
{
#region Props
public AppController.AppControllerClass appController = new AppController.AppControllerClass();
#endregion
#region Contructors
public FAST(AppController.AppControllerClass appcontroller)
{
this.appController = appcontroller;
}
#endregion
}
I have another few class, in which I would like to use the appController of FAST, the above class.They look like:
public class Forecast
{
#region Properties
private int _forecastnumber;
public int ForecastNumber
{
get { return _forecastnumber; }
set { _forecastnumber = value; }
}
private DateTime _startdate;
public DateTime StartDate
{
get { return _startdate; }
set { _startdate = value; }
}
private DateTime _enddate;
public DateTime EndDate
{
get { return _enddate; }
set { _enddate = value; }
}
private DateTime _deadline;
public DateTime Deadline
{
get { return _deadline; }
set { _deadline = value; }
}
private string _name;
public string Name
{
get { return _name; }
set { _name = value; }
}
private string _type;
public string Type
{
get { return _type; }
set { _type = value; }
}
private string _description;
public string Description
{
get { return _description; }
set { _description = value; }
}
private string _status;
public string Status
{
get { return _status; }
set { _status = value; }
}
#endregion
#region Constructors
public Forecast()
{
}
#endregion
#region Methods
public static void InsertForecast(Forecast forecast)
{
try
{
this.appController.Execute(appController.nDC.FASTData.InsertForecast(forecast.StartDate, forecast.EndDate, forecast.Deadline, forecast.Type, forecast.Name, forecast.Description, forecast.Status));
}
catch (Exception ex)
{
this.appController.LogError(ex);
}
}
#endregion
}
I want to be able to declare the FAST class once, passing in the AppController, then use my other classes freely, and they will use the appcontroller of the FAST class.
Can this be done at all? (inheritance?)
Thanks for any help.
It sounds like you simply want a static class for your FAST class. If you define the AppController variable as static, it will be accessible from anywhere.
I would say no to inheritance. Inheritance suggests an "is" relationship, e.g. "Forecast is a specialized version of the app controller." Aggregation, a specialized form of object composition, suggests a "has" relationship, e.g. "Forecast has an app controller."
http://en.wikipedia.org/wiki/Object_composition#Aggregation
You could add a setter method to set your FAST object as a property of Forecast:
public FAST appController { get; set; }
And then
var f = new FAST(new AppController.AppControllerClass());
var forecast = new Forecast();
var forecast2 = new Forecast();
forecast.appController = f;
forecast2.appController = f;
Here are two simple classes to illustrate my question:
class Widget
{
private int _widgetID;
public int WidgetID
{
get { return _widgetID; }
set { _widgetID = value; }
}
private int _categoryID;
public int CategoryID
{
get { return _categoryID; }
set { _categoryID = value; }
}
private string _widgetName;
public string WidgetName
{
get { return _widgetName; }
set { _widgetName = value; }
}
}
And them the second class:
class WidgetCategory
{
private int _widgetCategoryID;
public int WidgetCategoryID
{
get { return _widgetCategoryID; }
set { _widgetCategoryID = value; }
}
private Widget[] _widgets;
public Widget[] Widgets
{
get { return _widgets; }
set { _widgets = value; }
}
private string _widgetCategoryName;
public string WidgetCategoryName
{
get { return _widgetCategoryName; }
set { _widgetCategoryName = value; }
}
}
How would I handle this situation in the most efficient way?
Also, so you know, I will need to nest other classes the same way below the Widget class.
You should create a read-only property of type System.Collections.ObjectModel.Collection<Widget>.
Collection properties should be read only
Use Collection<T>
