Pass Entire Entity To Method Or Each Property As Parameters?

Oct 14, 2010

We're developing a business ASP.NET application. Is it better to pass an entire entity to a method or pass each property of this entity as parameters? What is the best practice?

Case 1. Pass Customer entity to a manager - InsertCustomer(Customer cust)
Case 2. Pass each property as a parameter - InsertCustomer(string name, string address...etc)

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?

Oct 18, 2010

I 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">

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?

WCF / ASMX :: How To Pass The Parameters Into Webservice Method

Jan 4, 2011

i am working in the webservice project. I have one project when i run it then shows the text box for parameters and return the result after passing the parameters.

But another webservice does not allow me to enter the paramerters when execute then list of methods displayed and then show the soap xml when click at any method.

what difference found in both webserivces are Excuting-one that have the Text boxes: Test: "To test the operation using the HTTP POST protocol, click the 'Invoke' button."

2nd One Not provide the parameter text boxes: Test: "The test form is only available for methods with primitive types as parameters"

Dont know how to fix that. Because i want to debug the webservice and as i am unable to provide the parameter then how can i fix it.

how can i pass the parameters in the 2nd webservice as it has different information mentioned above.

Javascript - Pass Multiple Parameters To OnSuccess Method Of PageMethod?

Dec 9, 2010

I'm calling PageMethod "SameMethod" from javascript method "caller" so that I can get some values from DB. After I get values, control is continuing in "onSuccess" method. Problem is that I need to use some variable values ("importantValue") from javascript method "caller" in "onSuccess" method.

function caller(){
var importantValue = 1984;
PageMethod.SomeMethod(param1,..., onSuccess, onFailure)

onSuccess method should be something like this:

function onSuccess(pageMethodReturnValue, importantValue ){

Is it possible and, if it is, how to pass multiple parameters (besides return values of page method) to "onSuccess" method of PageMethod?

MVC :: MVC3 RC2 Bug Binding From Request Parameters To Method Parameters?

Dec 10, 2010

Since ASP.NET MVC3 RC2 I encounter a bug when posting values to a controller method of which one of the parameter is a nullable int. Steps to reproduce:

I've created a test method


In MVC3 RC1 this was working without any problems with the nullable int

I don't seem to have the problem with a newly created MVC3 website. What could I have in my project that influence model binding to nullable int's? And why would there be a difference between RC1 and RC2?

Feb 21, 2010

I have a site with about 4 pages or so. I was asked to implement a very simple security (check if user in database, if not kick out) using active directory and validating against a table of users. I was simply thinking of createing a master page and making all pages inherit that master page. I would then authenticate the users from the master page.

C# - Forcing A Dropdown List For An Entity Property?

Jan 22, 2011

I'm trying to keep track of employees in my database. I have two tables, Employees and Departments. The Employees table contains a foreign key relationship with Departments through a column named DepartmentID.

Here's my entity:


I have a page that contains a form to add an employee. I'm passing the entity to my view page, and calling <%: Html.EditorForModel() %>

The problem is that the view creates a textbox for the DepartmentID.

How can I force the view to display a dropdown for DepartmentID that contains all the Departments in my database as the dropdown's list items? Is there a way to do this by just adding a metadata attribute to the property in my entity?

C# - Adding A Custom Property To Entity Framework?

Oct 19, 2010

I am using the Entity Framework for the first time and want to know if the following is possible - I have generated my classes from the DB, and have one called Category.

Obviously it has all my fields in the table (ID, CategoryName, SortOrder etc..) but I want to know if I can add a custom property which is not in the table, but is actually the result of a custom method.

I want to add a new property called 'CategoryURL' which is basically the 'CategoryName' property run through a custom method and returns a hyphenated string.

My initial thought is inheriting from the generated Category class and creating something like this inside?

public string CategoryURL
get{ return MyCustomMethod(this.CategoryName) }

Is this the correct approach? And will 'this.CategoryName' work as I think it should? Basically the end result is when I return a list of 'Category' I want this to be part of the class so I can use it in my foreach loop.

Use A Parameters Value As The Property To Be Selected In A LINQ Query ?

Aug 23, 2010

I am using LINQ-to-Entities and here is my query

public void SomeFunction(string searchField)
var data = from a in dx.SomeTable where [code]...

Now if I had to use the value of the parameter "searchField" as the property to be selected in the where clause then how do I do it ?

i.e I want to assign the value of the parameter "searchField" to the property I am checking in the where clause.

So ... the value of "SomeProperty" in a.SomeProperty must be the value of "searchField". How to do this ?

PS : I dont want a.SomeProperty=searchField. What I want is "SomeProperty" itself to be replaced by the value of "searchField" and then , this has to be checked to see if its equal to 270.

ADO.NET :: Entity Framework - Stored Procedure Mapping, Excecuting SP With Float Parameters Separated By Commas

Sep 27, 2010

Im using Entity framework with POCO entity generator template + SQL Server. I have mapping to stored procedure that takes two floats as input.

After executing function from code with two doubles as parameters: 1.23 and 4.56, SQL Profiler shows:

exec storedProcedureName @arg1 = 1,23, @arg2= 4,56

This is causing an error because it looks like that stored procedure takes 4 arguments, but it should take only two and there should be dots insted of commas in these floats.
