View 2 RepliesI've posted the same question in the Object Data Source forum. This is a link to it http://forums.asp.net/t/1554083.aspx. Maybe I should've posted here to begin with. There seemed to be some overlap so I wasn't sure which was the best on to post the question in.
I'm trying to get a better understanding of how I could've designed my app so that the Object Data Source could work with the properties of my business objects. Please read the other post to see how it's currently being done. Sorry for the link to the other page. I didn't want to post a bunch of duplicate information. I would love to get some suggestions for alternative ways of doing this.
Say I have a web site with a master page and an aspx page.In my ASPX page, I am pointing to my masterpage with the MasterType tag.<%@ MasterType VirtualPath="~/mymasterpage.master" %>Say, I've defined a label in the markup of my master page.If you look at the designer code, this label should be something like thisprotected global::System.Web.UI.WebControlIf I type in this "Master.label1", the complier will complain that the control is inaccessible due to the protection level" and rightly so, as label1 is automatically defined as "protected"

I am facing a decision now on how to make a "watch this item" function, like the one on ebay!I was thinking to make a SQL datatable with two fileds, for example: UserID and ItemID, anto store data there,
but I am afraid if I do it like this, my server performance will slow down. For example if I have about 10.000 users and everyone is watching just about 5 items, then my datatable will have about 50.000 entries. I am not really familiar with server performans when dealing with such big datatables. What do you think? Am I going to face problems with server performance
if I do it this way?Second method that I was thinking is to automatically create a datatable for every user in which ItemID will be stored later. With this method I will not have a huge datatable, but then I will have about 10.000 small datatables. Is this a better method?
I'm currently creating a Class Library for DTOs and was wondering if I should store an ID or an Object

View 2 RepliesVWD 2008 Express. Windows 7 (64 bit). I want all my work and settings for VWD 2008 to be stored in the public (shared) documents folder. There are settings under Tools>Options to specify where projects and templates are stored, that is part of the answer. However, whenever I open VWD it always creates a "Visual Studio 2008" folder in my personal Documents folder where it apparently stores some settings. How can I make VWD work entirely in the "Visual Studio 2008" public folder for everything and NOT create the personal folder?

I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is
((CompanyWide)this.Master.Page.Master).HtmlTitle = "now it is working";
i dont want to use "MasterType" i would rather cast..
I have user control in the master page. user control code behind page having public property called SetValue.
Now I want to set the value from content page .
I'm working on a webforms aspx app (not MVC) and I'm not sure if I should just create separate pages or somehow make multiple views on the same aspx page for the following scenario: Basically, I need to give the user the option to view a set of data a few different ways (essentially different group by's from a data perspective)... the data is always the same, its just a matter of how to arrange on the page...
each way I need to present the data will essentially consist of 2 repeaters, one nested inside the other. The outer repeater will display a nice header section with the nested repeater showing the list of items under that heading. view by book title (title is outer repeater, with the book list being the nested repeater, yes, multiple books with same title for this example - the app has nothing to do with books, this is just to illustrate)

Or, view books by publisher (here the publisher would be the outer repeater and the list, with different fields compared to first view, is the nested repeater.

so what do I do here? Just making separate pages is simple and would work, but is there something else I should be considering? There will be 3 different views, so 3 pages total if I went that route. Something is making me think I should be doing this all within one aspx page? maybe just toggling the visible property of the repeater controls? but then I was thinking each of these repeater controls is databound, and I assume even if they are not visible they still incurred database hits to get the data, right? and that could be bad?

I am working on a legacy application. It uses custom MVC framework and Windows Communication Framework service to bridge the Presentation layer with the rest of the application (i'll call this AppServer).
Every Entity in the AppServer inherits from BaseEntity which contains the method:
[Code]....
As you can see:
if the personObject was not null, but the ContactAddress was, [which is exactly what happens in the construction of a PersonObject in the event that no contact details are provided (hence they are not present in the HashTable and dont get created)] then the code will fail with a null reference exception.
SO:
Is there a fundamental flaw in the way that objects are getting created? It would be easy to point the finger in this direction, however, im sure there must have been some reason for the original architect to choose not to instantiate an empty ContactAddress object every time a Person object is referenced - EG if in a particular Presention->AppServer Request/Response cycle we only want a person's login details - we wouldn't care about the ContactDetails.
FINALLY MY QUESTION:
Is there a clean way to check for null objects within an aggregation, without doing something like:
if(Parent!=null)
if(Parent.child!= null)
if(Parent.child.child != null)
It just looks messy and it seems such a common problem, im sure there would be a better way of doing things.
I am creating an authentication service. This service has one of the methods to validate username and password and return a status based on it.
The validation method has bunch of things to check before it can say user is valid. This method has a pseudo code similar to this:
If UserName and Password is correct
If User Account is Locked (due to invalid attempts)
