C# - Generate HTML To Represent Class And Its Properties?
Mar 2, 2011
Currently I have a class that represents a document. This document needs to be displayed as HTML. I would like to have a method to call such as GetHTML() that would then call GetHTML() on any properties/sections of the document that needed to be rendered. I was initially thinking about using linq and XElement but am wondering if that may cause issues with certain tags in HTML. Would I better off using an HtmlTextWriter?

I'm a novice developer writing an ASP.NET application with VB. I'm having a little trouble getting my head around the partial class concept. If you use the partial classes as a code-behind for the presentation, how would these be represented in UML, in particular with a class diagram?

Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
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="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
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?

The CollapsiblePanelExtender looks like this:
<cc1:CollapsiblePanelExtender
ID="CPExtender1"
...
CollapsedImage=" [path to image] "
...
/>
I do not know how to do it this way:
<cc1:CollapsiblePanelExtender
ID="CPExtender1"
...
CollapsedImage=" [method call] "
...
/>
I have tried this:
CollapsedImage="<%# Eval( Namespace.Class.GetHelpImage() ) %>"
That DataBinding does not return the path to the image using a method call so I test the GetHelpImage() method call and learn it does not return the path as text.
I know the path to the image is correct because I can paste the text into the CollapsiblePanelExtender CollapsedImage property and the control will find and display the collapsed image.
// this method call does not return the text for a path
// so I am not even doing this correctly either.
public static string GetHelpImage()
{
return "[known path to image]";
}
// Image to test getting text from GetHelpImage() method call
<asp:Label ID="TestGetImagePathLabel" runat="server"
Text="<%# Eval( GetHelpImage() ) %>"/>
I'm doing this all wrong. Where's a blogged example of how to populate the control using an expression?

do you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).

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.
[Code]....
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.

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
{
DisplayMessage()
}
baseMessage:IbaseMessage
{
public Iview _view{get; set;}
DisplayMessage()
{
_view.Warning ="<message>"
_view.error="<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"

I am interested to know what happens with unused properties of a class when an object is instantiated?
Are there performance hits for having additional unused properties? What about complex properties that are accessing the database, but I'm not using them, are they still being loaded?

I am successfully injecting base class properties with spring.net 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>
</object>
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 asp.net (not MVC) and the class MyClass is a user control (ascx).

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?

I am using a custom membership provider. I want to expose additional properties under User class.
So in my custom membership provider class I added few Properties (FirstName, LastName, Address, etc) and set their value in ValidateUser(). However back in aspx.cs if I type User. I do not see FirstName, LastName and Address in intellisense.
Is what I'm attempting to do even possible? Or do I need to resort to using my own custom user class? In which case I wouldn't need to use custom membership provider because I can program my custom user class to do everything that custom membership provider can do. Only thing is I would need to pass this user object in session object.

I have a vb.net class with properties defined as follows:
Private m_Property1 As String
Public Property Property1() As String
Get
Return m_Property1
End Get
Set(ByVal value As String)
If IsNothing(value) Then
m_Property1 = String.Empty
Else
m_Property1 = value
End If
End Set
End Property
I can then set the values as follows:
classname.Property1 = "myvalue"
How do I set the value of a property that is defined dynmically eg
Dim strPropertyName As String = "Property1"

I am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.
Is there any way to access that class directly from the aspx page?
I know that i can make a method like:
width="<%= getWidthSize() %>"
and inside the aspx.cs to define this method to take the size from that static class.
But i am asking if this could be directly managed from the web aspx page...?
