Web Forms :: Class Properties Not Staying Set
Dec 20, 2010
I have an ASPX page (import.aspx) that creates a new instance of a class.
[Code]....
I set several properties during a function call in import.aspx:
[Code]....
I have confirmed that the properties are being set correctly via debugging the application.
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:
[Code]....
When the UploadApp function is called, CaseNo is NOTHING.

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?

I have added a static string variable inside a web page with it's class named VersionBase. The class is public, the variable is public, why can't I simply do VersionBase.MyString from anywhere inside the project like I can do with any other class?

We are trying to use a BasePage class (which inherits from Page) to populate and set the Meta Keywords and Meta Description Tags. I am using masterpages and below is an example code extract... According to examples on the internet, I could then set this also via the Page Directive using the MetaKeywords and MetaDescription properties, but they do not appear.
I have tried setting the CodeFileBaseClass="MyNamespace.UI.BasePage" but this does not work either. Using debug I can see that the BasePage classes' MetaKeywords and MetaDescription properties are not being set within my content page. I can access the properties but not set them.

== PAGE CLASS ==

I'm working on a project that uses a master page. When the page loads I'm calling a class (which I feed and ID into) to get back certain values for a location that the user has selected. Things like town name etc.
On the home page I have a user control which has some statistics for that location too.
Is there a way that I can get the user control to pull values from the class invoked by the Master Page (which has already been fed the ID, hit the db and pulled back the values), rather than creating a new instance of the class within the user control and having to supply the ID and hit the db all over again? This is now I'm calling the class in the masterpage. I have a method "CheckForStoredLocation" that goes off and gets all the data I need.

I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.

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.

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 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...?

I'm binding that Item to a DetailsView in Editmode. (I bind a List containing a single object of Foo, becuase I do recall that I can only bind IEnumerable<> classes to the DetailView)The binding is done via a ObjectDataSource
