Set View Properties From Another Class / Interface?

Nov 16, 2010

There is a SearchPage which has a properties ErrorMessage, SuccessMessage etc. This is basically a MVP pattern so for each page(view) there is IView that contains definitions for all the properties

I am using decoratoe pattern to set these peoperties dependingon the message type. There is another Interface IBaseMessage which has a method DisplayMessage() and a class BaseMessage which implements the interface. This class has a definition of the view

Interface IbaseMessage
public Iview _view{get; set;}
_view.Warning ="<message>"

Here, I am not able to set the message to the view properties. I am getting the error as "Object reference not set to an instance of the object"

Architecture :: Use A C# Class Or A Interface?

Feb 3, 2011

I have a block of SQL statements that I like to use as a sort of function.

I was thinking that I could make a class and inherit all of the master function, then add the parts that I need for other sections of the program in a sub class.

The problem is, up to this point I've been programming ASP .Net through visual studio, and it's kind of just programming behind controls. I'm not sure where to put the class/function/method/interface, or whatever we call it.

Of course you probably know that visual studio creates a bunch of partial classes when you do an ASP. Net application... so.. to get access to a function like object, across classes.. use an Interface?

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13, 2010

Using the following Webservice definition using aClientArgs as a complex type:

public class Controller : System.Web.Services.WebService {
public void save_client(aClientArgs client)
// Save client data
Then defining aClientArgs as a sub-class:
public class aArgs
public string id = null;
public string name = null;
public class aClientArgs : aArgs
public string address = null;
public string website = null;
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="">
When I'm expecting the following:
<save_client xmlns="">

So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

How To Make A Class Recognize That An Interface Found In A Separate File Exists

I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...

How can I make the class recognize that the interface exists but is in a different file?

Here's some code:

Alternative For Static Method In Interface - Enforce Implementing Class-level Methods

Oct 28, 2010

I have a hierarchy in my website project as below:

[CustomControl1 - folder]
- CustomControl1.ascx
- CustomControl1.css
- CustomControl1.js

I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:


where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.

I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?

Custom Server Controls :: Implementing An Interface From A Class Library In A Custom Control?

Jul 8, 2010

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:

Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)

notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:

using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

I set several properties during a function call in import.aspx:

I have a user control on import.aspx. There is a function on import.aspx that gets called by a button click on the user control.

This function is:

MVC :: Can't Reference To Some Properties In Model Class

Mar 31, 2010

I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.


and the error message

Compiler Error Message:
CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.

Chained Base Class Properties Not Injecting

Apr 2, 2010

I am successfully injecting base class properties with with just a class that inherits from a base abstract class. Lets say Class MyClass : MyBase, and I am successfully setting a property like this:

<object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true">
<property name="MyBaseClassProperty" ref="anotherObjRef"></property> </object>

Where MyBaseClassProperty is a property on the base class. Now I have another abstract class between the old base class and the instantiable class and I am trying to set properties on both the abstract classes. So MyClass : MyNewBaseClass and MyNewBaseClass : MyBaseClass. I have an additional property on the new base class (MyNewBaseClassProperty) and I am trying to inject it like this:

<object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true">
<property name="MyBaseClassProperty" ref="anotherObjRef"></property>
<property name="MyNewBaseClassProperty" ref="someOtherObjRef"></property>

The property on the old base class is being injected but the one on the new one is not - and I am not getting an error or anything (so I am pretty sure my config is good), that property is just null! I am on (not MVC) and the class MyClass is a user control (ascx).

MVC :: Assign Values To Base Class Properties?

Sep 29, 2010

In my controller have a FormViewModel which inherits from a domain class declared in dbml. In the constructor of the FormViewModel I want to do a shorthand assignment to the inherited class properties with the passed in object (ie thisPerson) without iterating through each property of the inherited class and assigning its value with corresponding property in the passing in object. Should I use super, base, this, or something else?
