this is a bit of a nomenclature question:what is the correct way to describe the relationships between these classes (the thing that throws me off is the use of generic types here):

I use below code to showing date in Persian in my site
DateTime miladi = DateTime.Now;
System.Globalization.PersianCalendar shamsi = new System.Globalization.PersianCalendar();
DateTime shamsidate = new DateTime(shamsi.GetYear(miladi), shamsi.GetMonth(miladi), shamsi.GetDayOfMonth(miladi));
Lbldate.Text = (shamsidate.ToString("yyyy/MM/dd", System.Globalization.CultureInfo.InvariantCulture));
But below error happen

I'm not 100% sure that this is the right forum, but here goes.Is it possible with ASP.Net to reliably determine if the client (i.e., the browser) is using a proxy server? I'd like to prevent proxy users to a particular site.
View 3 RepliesI have an intranet site that is used to pull several other intranet applications/tools and database info to one place.One of the most popular features uses iFrames and jQuery tabs to give a broad overview of activities, signal etc in a network node. Chrome and Firefox eat it up with no problems, IE will work if you override the cookie policies that restrict 3rd party cookies
without a valid p3p (what a worthless standard). IE also works if you already authenticated yourself on the individual sites and the session cookies are still valid.
I have a web service I need to connect to. But when trying to connect to it through visual studios, I get this error. The request failed with HTTP status 405: Method Not Allowed. I have the wsdl files on my location machine. I was told to create the proxies from these. The problem is I'm not quite sure how. This seems to be a little over my head right now. Not the best project to learn WCF or WSE on. Does anyone know how to create the proxies from wsdl files on my local machine. The services themselves are pretty simple, they just have security elements in the headers. UsernameToken. And then some custom fields.

View 5 RepliesWhat is the best approach to one to many relationships?
This is my scenario:
I have a simple one to many relation:
Customer
CustomerID
Name
tel
CustomerNotes
Id
Note
customerID
I want to have a DETAIL view of customers and CREATE view for CustomerNotes all in the same page.
I create CustomerController and the different views and its respective actions for edit, create, delete, etc.
I also create a CustomerNotesController and the views and actions like before, but I made the views PARTIALS
I put a RENDERPARTIAL for the CustomerNotes create view in the Details view from Customer.
When I run the app, the page is render as expected: It shows the detail info of the customer and bellow the create form for the notes. However, when I click SAVE, nothing happens. I put a breakpoint in the notes controller and never get hit.
I also try with RenderAction and don't work at all.
I want to display data in a listbox on the bases of group.
Eg.

Mumbai
Delhi
UK
England

I'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.
I need to change culture of the specific aspx page bases on the main user's culture.I am able to fetch the data that which culture main user have.But some how I am not able to set the same culture for that aspx page.I had written the below code for that.

But that is not working it sets the default culture of the browser.
I'm having a hard time wrapping my head around how to use the Memberships in MVC. I know there is the built in ASPNETDB database which has all the basic tables for users and such. But what if I wanted to add a relationship between one of my custom tables and this built in user table?
If I had a database table that contained blog comments, we'll call it Comment. And each Comment had a userID associated with it could I do something like?
User.Comments.Add(someCommentObj)
Does anyone no of any good resources regarding many-to-many relationships? More specifically on displaying data from many-to-many tables in ASP. Struggling to find anything but I may just be over complicating things!
View 18 Replieshow to create C# classes to represent one to many relationships in C#. I have a Customer and an Address table in my database. I also have a Customer class in my C# solution but how do I introduce the multiple address element? Do I have a separate Address class? Do I create a subclass in the Customer class or create a method in Customer called GetAddresses of type List which contains all of the relevant logic? In my code I need to be able to return a customer with all associated addresses and I just cannot picture the best way to achieve this using OOP.
View 9 RepliesEF is so frustrating. I can't seem to be able to get my head around what I need to do so I can delete an object. I seem to be able to remove the object but not the related child objects. Can anyone tell me what is the rule of thumb when you want to delete all related child objects of a given object? I've tried loading all related objects like this:
Entry entry = ModelContext.GetObjectByKey(new EntityKey("ModelContainer.EntrySet", "Id", id)) as Entry;
entry.ChildEnteries.Load();
if (entry != null)
{
ModelContext.DeleteObject(entry);
ModelContext.SaveChanges();
}
I get errors related to the relationships: A relationship is being added or deleted from an AssociationSet 'EntryEntry'. With cardinality constraints, a corresponding 'Entry1' must also be added or deleted. Why can't I just load the object using modelcontext.GetObjectByKey and remove it along with its child objects? My other question is can I delete an object using Entity command like so? DELETE e from objectset as e where e.id = 1 I've tried few variations and all of them throw exceptions.
So I am working on an MVC project to put to work the studying I have been doing. I am wrestling with the concept of Database Table relationships and foreign keys. I am working on a simple ecommerce site (displays products, shopping cart, user accounts..etc).
I have the following tables to start out with:
1) Products
2) Categories
I setup the Products and Categories tables to have a ProductId and CategoryId respectively. In my MySQL db, I created a FK on the Products Table to relate to the CategoryId field on the Categories table (I am not sure this was correct to begin).
My expectations for the way the database would handle the table relationship: I didn't want the DB to do anything with the products table if I deleted a category out of the Categories table, or vise versa. The only thing would be that the category field in a Product would be blank (or default) if their category was removed.
Finally, do I have to do anything in my entity classes such as in the Products class, add the ProductId to the Category.ProductId?
Eventually, when I Orders and Users to the project, I can see a relationship where each user -> many orders -> each order has many products -> and each product is in one category.
But I am having a hard time understanding how or if I should be setting up a Foreign key relationship in the two current tables of Products and Categories and if so how to setup my entity class in relation to that FK.
I have been experimenting with WebMatrix, specifically the ability to connect to and use SQL CE data.
My question is:
When I am creating a new SQL Compact database with several tables, how do I define relationships between the tables?
The "Relationships" button in WebMatrix is always greyed out. Is that because it is still in Beta? Or am I missing something?
Using dataloadoptions i have tried the following example
[Code]....
Now i need to ask how can i display Category ID and Category Name of the productID (i am supposing that One product can be in at most one category) by extending the above example Regards.
Say I have this entity with a lot of attributes. In the input form I have decided to implement a wizard control so I can collect information about this entity in several steps. The problem is that I need to collect information that has been modeled has many to many relationships. I am planning to use a telerik gridview to manage this (add/edit/delete), the problem is where do I store that data since the entity in a insert form is not created on the database yet. OK so I can store all that info in temporary lists residing in the viewstate, waiting for the final submit where I dump all that in the DB, but one of the steps I am collecting files...now storing files in the viewstate is out of the question, same as as storing them in the session...I have been thinking of implementing in a way that the user has to submit some info first (say first 3 steps), commit the data to the database creating the parent entity and then start inserting all the childs entities...but this will get weird as it's confusing since on the first steps you not saving the data to the DB and on the next ones you are commiting directly...
View 1 RepliesJust a quick question for those more familiar with FluentNHibernate. I've read the quick start things, and the docs on their site, but am still a tad off.
