C# - Access Parent Class From Custom Attribute?
Jun 6, 2010Is 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?
VS 2012 - Class Needs To Access Application Space In Parent
Sep 19, 2015I'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

Forms Data Controls :: Access A Method Of Entity Class From A FormView?
Feb 24, 2010I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?

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.

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?
Oct 18, 2010I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?

Parent Controller Class In .NET MVC 2?
Jul 26, 2010I'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.
View 1 RepliesADO.NET :: Retrieving Parent (POCO) Class In WCF
Jan 11, 2011I 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.

View 2 RepliesMVC :: Redefine Parent's Variables In Partial Class?
Dec 29, 2010i 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
