How To Access Label In Parent Class Of Code Behind Class
May 24, 2010
I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?

Is it possible to access a parent class from within an attribute.
For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here.
He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute.
I would like to do something like the below,
public ExampleDropDownViewModel {
public IEnumerable<SelectListItem> Categories {get;set;}
[DropDownList("Categories")]
public int CategoryID { get;set; }
}
The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this?

I am going to have multiple "types" of an object and I am really not sure how best to retrieve/save those multiple types without having a separate save/retrieve for each type.
My classes:
[Code]....
I hope this makes sense. I'd rather not add a "type" column as I have this in another part of my database and I am not really liking it too much
UPDATE
Here's more info/questions for clarification, if necessary.
I'm really at a loss for how to incorporate them into my repository pattern.
When I call getEvaluation, I want it to return an abstract Evaluation, but I'm struggling with this code. Same with Saving - any insight on this would be excellent
UPDATE 2
Database:
Evaluations
Id (PK)
Comment
EvaluationType1
Id (FK to Evaluations.Id)
Field
EvaluationType1
Id (FK to Evaluations.Id)
Field
So, in getEvaluation(int id), I need to figure out what type of Evaluation they want. Does this mean I should pass in a type? Same is true in saveEvaluation, But I can do a switch/function map to see what Type it is.

I've got a class that create a report in a PDF - looks like this
Code:
Option Explicit On
Imports PdfSharp
Imports PdfSharp.Drawing
Imports PdfSharp.Pdf
Imports System.Data.SqlClient
Public Class acsReportWriter
[Code] ...
And I access this class from within a web service call like this
Code:
Using acsRpt As New ACSReport.acsReportWriter
acsRpt.StartDocument(strViewName, strTitle, username)
Using dcn As New SqlConnection(connStr)
Using cmd As New SqlCommand
cmd.CommandType = CommandType.StoredProcedure
[Code] ....
So - in that web service I can access APPLICATION like this
Code:
With Application
.Lock()
' need to do work here
.UnLock()
End With
I need to be able to access APPLICATION from the acsReportWriter class to put status message every so often so another AJAX POST can fid out how many pages are done.
I'm having a hard time even adding IMPORTS to SYSTEM.WEB in the acsReportWriter class

if we can include a css class from code behind for a link button. I have been trying this since a while but I was not able to get it done. It does not show a hyper link nor css works. Please refer to my code and see where am I doing wrong.
string link1 = "google.com"
lblclick.Text = "<p>See what our page looks like by clicking "
+ "<asp:LinkButton CssClass="+"linkclass" + ">"
+ link1 + "</asp:LinkButton>

I have a Web Site project running on VD2008, with an Access back end and .NET 3.5, C#.
I have created the project several times and added the usual App_Code, Pages, App_Data, Properties, folders. I created a Master Page and several content pages BUT I am unable to get to the folders or root where there is a Class (code) file.
I have tried all the usual lines...
using SumaCard.App_Code
OR
SumaCard.App_Code.FTP_Code ftpc = new SumaCard.App_Code.FTP_Code();
but nothing works? I have been hasseling over this for 2 days now.
What have I missed? Maybe I built the project wrongly? (Project | New Project | Visual C# | Web | ASP.NET Web Application |??

I've been working on a rather large web application that requires a specific id param in the url for every page visited (for example, /controller/action/id?AccountId=23235325). This id has to be verified every time someone visits a page. want to reduce code replication as much as possible, and was wondering if there is a way to use an init method or constructor in a controller that inherits the MVC controller, and then have that controller extended by the others.

I have an interesting problem with a WCF Service I am creating. As background fodder my solultion uses MVC 3 RC2 as the web interface. I am developing the solution as an N-Tier application using the Entity Framework 4.0 with POCO Self Tracking Entities, repository and unit of work approach. I am using the STE's more as an advanced POCO since STE do not seem to play well as of yet in the real world as they were meant to and since they do seem to give me better interfacing with the DB through my layers still. Additionally, I am incorporating WCF into the solution as the backend for the models based on info I am reading and the fact that I will need to also access these services via a windows service app on the client computers.
So, I have a datastore which includes my edm and the repositories. The POCO STEs are generated in a separate layer in what I have called my Domain Models. Within my domain area I also have a Core app holding my utilities. I am currently incorporating an additional domain element as a WCF service using the RESTful template. This WCF will be servicing both my MVC controllers and a Windows Service app on the client computers.
Now, on to the problem: Within this solution I have an Entity Set of People (or Person?). Within that Entity set I have a chain of inherited entities as follows Person->User->StaffMember->Provider where Provider is the resultant child. Within my WCF I have a ProviderService, a StaffMemberService and a UserService. In each of these Services one of my OperationContracts is a Get(string id) amongst others. the Get(String id) contract is the one that is causing me problems. Within that Get(String id) contract I do the following for the User:
[Code]....
and for the Provider:
[Code]....
Now, what has gotten me completely confused is that the Provider one works like a charm. But if I use the UserService to call the User of the same Id (Since User is a base class for Provider, this should work) I get an error saying it was a bad service call. (The ProviderService, as stated works and returns all the correct data). When I debug it, the UserService Get(String id) function actually works as expected up to and through the return statement (ie the user variable actually contains all the proper data that I would expect on the call). It is only after the return that I get the web page giving me that error and points me to the help page for the service. (I am using the browser to view the results at this point only). </P><P>I am assuming it has something to do with serialization? But why is it displaying the derived class with all expected data, which yes does include the data not being displayed as a user data, I am calling the data using the same UserId. I am not expecting someone to inspect my code, but to be a traffic cop and point me in the direction I need to look.

i am using linqtosql dbml to create table classes automatically.
however each time i update my database or dbml diagram, it refreshs designer.cs file and all code i wrote is gone.
so, i decided to make partial class to keep certain information alive.
but here is my question :
for example, User class is defined as follow in designer.cs file :
[Code]....
public string UserID{get;set;}
}
but if i do this, i get error message because UserID is already defined in designer.cs file.
should i delete all UserID variable in designer.cs each time i update the dbml?
i believe there should be a better way to do it
