View 3 RepliesI am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.
[code]....
I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?

View 4 RepliesI have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section.
My main page is Sync.aspx and has a code file Sync.aspx.vb with it.
One of my code files is SyncDatabases.vb and in it I have created
Public Class SyncDB
In that class I have created some routines such as
Public Function ReadMSDB(ByVal SQLString as string) as Boolean
In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).
My problem is that if I try:
Form1.txtOutput.Text = "Hello world"
or just
txtOutput.Text = "Hello world"
it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.
im reading checkbox value which is checked on my gridview but as per my code is missing the 1st one which on top but i select from the middle then it is working fine here is link for gridviewhelper classes [URL] and im calling this code from gridviewhelper classes on page load event
Dim helper As New GridViewHelper(Me.GridView2)
helper.RegisterGroup("heading", True, True)
AddHandler helper.GroupHeader, AddressOf helper_GroupHeader
and here is my code
Dim sc As New StringCollection()
Dim id As String = String.Empty
For i As Integer = 0 To GridView2.Rows.Count - 1
'loop the GridView Rows
Dim cb As CheckBox = DirectCast(GridView2.Rows(i).Cells(2).FindControl("CheckBox2"), CheckBox)
'find the CheckBox
If cb IsNot Nothing Then
If cb.Checked Then
id = GridView2.Rows(i).Cells(1).Text
sc.Add(id)
MsgBox(id)
End If
End If

I was wondering if you should write code so that external classes and functions of that external class can access the webform controls in the main class???
Or should you only use the external class to process some data, return that data back to the main class (that instantiated that external class object) and then have an internal function in the main class to deliver the data to the control? (back to the screen)
Is there anyway I can extend LINQ classes through different namespaces?Typically in my class libraries I have a namespace for each class object and their associated DAO and service classes in a folder of my project, therefore on the front-end I can only use the namespaces associated with the given page and not clutter my intellisense or load in a bunch of excess stuff.
However, I have found that upon adding my .dbml LINQtoSQL file, whatever namespace that is in, whether it's the project root namespace or a custom one, is the only namespace I can use partial class extension in.I have tried even creating a custom workspace (placing the .dbml file in a folder) and then including a using statement to that namespace and I still cannot extend the partial classes.Is there anyway I can do this? Or to have the .dbml file count as being in every namespace? I don't want to remove all namespaces but the root one either.such when I try doing the partial class from a different namespace I get the following error:
Error 1

I came across the article few days ago where somebody said that it's possible to automatically break down ClassName.Designer.CS into multiple classes.
So instead of having Customer and Order class definitions in one .CS file I'm going to have 2 .CS files: Customer.Designer.CS and Order.Designer.CS
Do we have to do something special to have ASP.NET partial classes aware of controls that are declared in our user control's base classes? The partial classes keep generating declarations for controls in the base class which mean the controls in the base class get hidden and are null.

If I included a page class into a namespace the Profile page property becomes undefined.Why and how to solve this problem.For example I want to include my pages classes into a namespace MyProject.UI.
View 2 RepliesI have a BasePage class that all of my content pages inherit from. In my BasePage, I have many Import Statements. It seems as though they carry over into the derived class as one would expect. However, if you were to try and access code in the client aspx design page, as you would in the code-behind, you run into problems.
For instance, in my BasePage i have a Public Enum named ThemedSites. It's just an enumerator that lists the 5 different themes my site could be skinned as. I, at times, need to do different things in code, and in design, depending on what theme I'm currently in. I have a Public Property named CurrentSite (might have been more appropriate to say CurrentTheme, but that's besides the point). CurrentSite's return type is ThemedSites. So in code, one would say something like:
[Code]....
This works great in any page that inherits the BasePage class. This falters when that very same logic is used in the design page like:
[Code]....
Now, it works if you fully qualify both sides of the condition, but that's not my question. My question is: why isn't the Imported NameSpace in the BasePage recognized in the client-side server tag, as one would think it would be, according to how it IS recognized in the server-side code-behind?
I've been tinkering for hours and I can't figure this out. Seems like it should be pretty straight-forward. Is it possible to use reflection to get a reference to a partial page class given the page's name and path so that I can iterate through the page and examine its controls? I am not looking to examine the currently loaded page, but another page within the same website.
View 4 RepliesI have some code in my new asp.net app that I need to share. So i created a shared class called
"utilities.vb" and put it in the APP_CODE folder. There is a function I have in there that pulls a person's image based off of their MemberId.
[Code]....
And I can call this function from my page using utilities.FcnGetMemberImage(). Ok, so all good so far until it complains about...
"Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class"
when referring to the Server.MapPath()
But the problem is that if I don't make it a Shared Function, I can't access it from my other pages. But if I do make it a Shared Function, it throws this error. The fix is supposed to be that I either don't share the function, or
"add the shared keyword to the member declaration", according to Microsoft at
http://msdn.microsoft.com/en-us/library/xfsswe45.aspx
But I'm not exactly sure how to "add the shared keyword to the member declaration" or what this means exactly and how this might affect other parts of my code?
Or is there a better way to work around this dilemma?

i have found the following code in one of the web applications. Is it possible to have an aspx page inherits from two different classes?
<%@ page language="C#" masterpagefile="~/email/EmailMasterPage.master" inherits="email_PassReset, App_Web_klsfx623" stylesheettheme="email" %>

I have two different classes, and would like to (for example) alter the text of a label control contained in one class using the other. At present I experience the following error (e.g.):
"ProjectName.PageName.Protected WithEvents ControlName As System.Web.UI.HtmlControls.HtmlGenericControl' is not accessible in this context because it is 'Protected'."
All the subroutines in my PageName class begin "Protected Sub...", however even if I change these to "Public Sub..." this does not fix the problem. How do I achieve this? Also, are there security implications to not protecting subroutines?
I have a virtual directory called "MySite.web", and a folder inside this directory called "Sell" where I have my webform Create.aspx and several user controls like CreateAd_CarsAndTrucks.ascx and CreateAd_Motorcycles.ascx.When I try to compile, I get several errors in Create.aspx stating that public partial class Sell_CreateAd_CarsAndTruck, Sell_CreateAd_Motorcycles are not recognized. I am looking at both classes right now (they're in the same folder), so I have no idea why the compiler's not finding them.One odd thing is that, for a moment, it did find one of them (Sell_CreateAd_CarsAndTruck), but from an assembly in either folder "Temporary ASP.Net" under c:Windows or the one in c:usersusername. So I closed my IDE, and deleted both folders. When I open the solution once again, it recreates "Temporary ASP.Net" under c:usersusername and then creates a "App_Web_createad_carsandtrucks.ascx.5a5f4927.ebg000r0.dll" that it uses as definition for the class. But it never uses the actual class as a definition. Basically, when I right-click on the class instance to view its definition, it takes me to metadata.
