How To Get MVC Ajax Partial Load To Work
Sep 4, 2009
I was following the example laid out here for implementing Ajax panels in MVC. I'm using VB.NET, but the conversion is pretty straightforward. However, I can't seem to get it to work?
Here is my code:
HomeController:
Function Index() As ActionResult
Return View()
End Function
Function Archive() As ActionResult
Threading.Thread.Sleep(5000)
Return View()
End Function
[Code] .....
When I run it, all I see is the ajax-loader animation endlessly. When I run it in debug mode, it never seems to trigger the Archive action.

does it reload the entire page or does it have the intelligence to only send the necessary js to update the needed parts of the page that have changed?
if it does the latter that would be a god send, however im probably being dreamful. it probably returns the entire view without any regard, right?
edit: answer seems to be no, everything is returned.
edit added: 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)... maybe an idea for a codeplex project? or maybe something like this exists?

If I have a parent object (Parent) which has a List(Of Child) objects as a many-one relationship. Is it possible to return a Parent with a subset of it's child objects (eagerly loaded)? I am using VB and Criteria.
e.g. If Parent 1 has 50 children (20 type X 30 type Y) and I want to return the Parent with a collection containing only type X.
I only want a collection with a size of 20 with it's eagerly loaded children?

I have a main page that loads a content of a div:
var content = $("#content_layout");
//some code here
content.load("claim_form.aspx?claim_no=" + file_number);
The claim_form.aspx has a drop down, and based on that drop down it should show the apropriate input fields. I set the index to be 1 and automatically load the first set of inputs. Here is some code to explain it better:
$("#request_type").change(function(e) {
index = document.getElementById("request_type").selectedIndex;
if (index == "0") {

I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?

This is the strangest thing, I can not figure out why this is happening. When I delete a radio button from my form which is used to filter data in a database Form_Load stops working.My project consists of a database and a web browser. The database has a search filter options.[code]For some reason it didnt load my settings on start up. I made a button which displayed True/False in a text box to check if it was saved in my settings, it was, it just didnt want to load. So I deleted it and everything broke! Nothing in the code is referenced to the RadioButton or its code.
Have I done something wrong or is VB just messing with me? There is obviously a bunch of more code, I just posted what I think is relevant to the issue. If you feel something is missing, tell me and Ill post it. ied to change the RadioButton with a CheckBox, and I changed the code from "Me.ExampleTableAdapter.FilterHide..." to "Me.Example TableAdapter. Fill...", which is the same as in Form_Load. It works if it starts checked. If I remove this code or delete the CheckBox nothing works even though the same code is in Form_Load. If I start off with the CheckBox in an Unchecked state nothing loads, if I check it everything except the Browser works for some reason.

I am making changes to my companies internal paysite in order to come into compliance with the new credit card regulations. We have decided that when we get a split tender transaction that comes through we want to get the remaining balance along with how much was on the card to start out with and send that info back to the customer service rep with a message relaying the need for another payment source along with the remaining balance and the amount that was originally on the card.
Instead of chaining the transactions together with the split tender Id we have decided we would like to finalize each split tender transaction with a prior_auth_capture and then request the next payment source and amount and process that transaction in the same manner. I know that we are side stepping the functionality some but those are my orders.
My questions are, is this feasible and possible and how do you do this in code? I am using the C# SDK to implement this in VB.NET 2008
My thoughts are that I would have to process the transaction for the amount passed as a auth_capture transaction and then some how do the prior_auth_transaction with a zero amount or something?

I have the follow VB.NET class definition:<Serializable()> Partial Public Class Customers End Class
Inside another file I have the same thing (with different methods and variables of course). When I compile, I get the following error:Attribute 'SerializableAttribute' cannot be applied multiple times.The error is pretty self explanatory. My question is though, if I just mark the one class as Serializable(), can I assume the entire class with be marked as serializable()? In other words, Do I only need the serializable() tag in 1 spot in the class?

I have a lot of information distributed among some tables in a database (and must likely it will all be represented into oop). I will need to create text files with different formats from the same data depending on the request. My idea is to create a design that will require no coding if such formats are to change of be added.I was thinking in using some sort of XML magic trick to accomplish this but I have no idea how to. I am also open to new ideas.

We have a big Form class that we like to split into peaces using partial class approach That could be done by manually modifying a project file, and adding MainFormPN.vb entry
<Compile Include="MainForm.vb">
<SubType>Form</SubType>
</Compile>
<Compile Include="MainForm.Designer.vb">
[code]....
The issue with this approach is when double click on this item in VS2008 IDE it shows new empty form, not MainForm UI. It looks like VS2008 does not support multiple partial classes for a Forms.

I'm still learning so this might be completely wrong. I have built a multi-user web application for internal purposes. I have split my code up to make it more manageable and have run into some problems. I suspect that I have done something very silly!
I have a class in a separate file (quoteStatus.vb) in App_Code here it is:
Imports Microsoft.VisualBasic
Imports System.Data.SqlClient
Imports System.Data
Public Class quoteStatusHelper
[Code]...
This seems really wrong, as the value seems to be held in the partial class after the first run. So if I have two users accessing the class the public shared dim is changed for both users! There must be a better way to do this. I have looked everywhere and I'm more confused now than when I started off..How can I make QuoteStatus in the partial class unique to every user and access it from my code.

When you create a new asp.net page in VS 2008 and choose code behind, it also creates the typical aspx.vb or aspx.cs file to go along with it.
At the top of those files, VS names the 'Partial Class' name the file structure and/or name of the aspx file.
The question: Is there a best practice for this? Can I just use a single class name for all the pages in my application or perhaps a single directory instead of having to give each one a unique name?

I'm using Linq to SQL, which generates partial classes and partial methods. You then extend that generated code by implementing your your customizations manually in another partial class. One of the hooks L2S gives you is the ability to implement partial methods that get called when a property changes. For example, if you have a property named "MyProp", then you can implement a partial method like so:

I would like to create a partial class for my form. I have a lot of events, and it gets messy, so I would like to break up sections into their own files. The problem: When I create a partial class of my form, say:
Partial Public Class Form1
End Class
Visual Studio decides I need another form for this partial class.
1. How do I create a partial class for a form?
2. If I cant do that, how can I break up all the events in my form into different files?

I am reading a book (ASP.NET 3.5 Enterprise Application Development with Visual Studio 2008: Problem Design Solution, WROX)The source code is written in C#, but I am a VB guy, so I am giving it a try. Somewhere in the 2nd chapter, there is a Linq to Sql file used that is generated by drag&dropping the DB tables from the Database Explorer. Because some tables have the same type of fields, there is an interface generated called IENTBaseEntity. The writer says its a good practice to implement this interface in another partial class (not the designer.vb file!). The reason for this is that when the LinqToSql file is modified (and regenerated) the changes wont be lost.
In C# this solution is easy to do (i think), but in VB.Net I get an error, because the concerning properties in the LinqToSql file do not append the 'Implement IENTBaseEntity.Property' line. When I press [Enter] after the interface implementation line, VS generates other properties like this
Partial Public Class ENTUserAccount
Implements IENTBaseEntity '--->This line results in the error
' This is not the way it should be
Public Property InsertDate1() As Date Implements IENTBaseEntity.InsertDate
Get
End Get
