View 3 RepliesI'm trying to edit some code in a website solution which I have opened in vs. I notice that there are only 3 files showing and it doesn't have a web.config and it uses a popup box when I debug it instead of opening up a webpage like default.aspx. I see that I have to use debug.write and not response.write as I normally would. How can I see my debug.write statements?
View 1 RepliesDataTable 1 :-
Caption |ID
------------
Caption1|1
Caption2|2
Caption3|3
DataTable 2 :-
Name |ID
------------
Name1|1
Name2|2
I want to compare the above two data tables and fetch the value "Caption3" so I can display a message on screen that "No name for "Caption3" exist!"
I have tried merging as follows but it's fetching DataTable 2 as it is in dtTemp !
datatable1.Merge( datatable2);
DataTable dtTemp = datatable2.GetChanges();
Also tried the logic as follows that removes rows with same IDs in both tables and updates datatable2's rows and only the ones that don't have duplicated IDs will remain...This didn't work either.
if (datatable2.Rows.Count != datatable1.Rows.Count)
{
if (datatable2.Rows.Count != 0)
{
for (int k = 0; k < datatable2.Rows.Count; k++)........
How do I fetch those "CAPTIONS" whose corresponding "NAMES" do not exist?
Note:- Rows in both datatables will vary based on some logic. What I want is to fetch that CAPTION from datatable1 who's KCID doesn't exist in datatable2.
edit:- How else do I loop through datatable1's rows and check which ID(from datatable1) doesn't exist in datatable2 and then print those captions on my page?
@CodeInChaos:: I have not worked with Linq-To-Objects at all so not able to understand your code :/
Is there any other way to loop through that datatable and fetch "caption " who's correcponding "Name" doesn't exist in the datatable2?
I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

View 1 RepliesI've gone rounds with this ever since I started programming classic ASP 12 (or so) years ago and I've never found a great solution because the architecture of ASP and ASP.NET has always been a swamp of bad practices, magic shared singletons, etc. My biggest issue is with the HttpApplication object with its non-event events (Application_Start, Application_End, etc.).
If you want to do stuff once for the entire lifespan of an HTTP application, Application_Start is the obvious place to do it. Right? Not exactly. Firstly, this is not an event per se, it's a magic naming convention that, when followed, causes the method to be called once per AppDomain created by IIS.
Besides magic naming conventions being a horrible practice, I've started to think it might be a reason there exist no such thing as a Start event on the HttpApplication object. So I've experimented with events that do exist, such as Init. Well, this isn't really an event either, it's an overridable method, which is the next best thing.
It seems that the Init() method is called for every instantiation of an HttpApplication object, which happens a lot more than once per AppDomain. This means that I might as just put my startup logic inside the HttpApplication object's constructor.
Now my question is, why shouldn't I put my startup logic in the constructor? Why does even Init() exist and do I need to care about Application_Start? If I do, can anyone explain why there is no proper event or overridable method for this pseudo-event in the HttpApplication object?
And can anyone explain to me why in a typical ASP.NET application, 8 instances of my HttpApplication are created (which causes the constructor and Init to run just as many times, of course; this can be mitigated with locking and a shared static boolean called initialized) when my application only has a single AppDomain?

Has anyone been able to cache .aspx pages using the HTML cache manifest? I am porting an html application over to asp.net (and mvc2) and I get a 404 error when trying to cache any *.aspx page.

View 3 RepliesI have some datatables in a LinqToSql entity model (edmx) that are structured like this: SalesOpportunity *<-1 User *<-1 Person i.e Many SalesOpportunities / 1 User, Many Users / 1 Person Anyway, My DomainService is SalesOpportunity centric, and I want to serialize info about the person into the metadata class. I can serialize data about the user without any problem like this:
MetaData Class:
<Include("UserName", "UserName")> _
Public User As User
DomainService Class - GetOpportunities()
Return Me.ObjectContext.Opportunities.Include("User")
I've been trying for several hours to get the Person information. If you have any tips, I'd be grateful to hear them.
