I am creating a web service that returns the list of states. How do I create an object in C# in the web service that will return multiple values (of properties of an object). Currently, the way I am doing it, it only returns the last value pulled from the database. Do I need store an array of properties?
[code]....
I'm using Visual Studio 2008 with SQL Server Express databases in my .net 3.5 website
I have three tables I'd like to make entries to when the user completes a wizrd i've setup on a web form.
The First Step - The user enters basic information about their "Case". The table looks like so:
db_Cases - CaseId PK auto int, CustomerId, etc fields
The Second Step - The user enters information about the "Debtors" that are related to this "Case". Think of this as being products....The only difference is these records wont be used over and over again like a product would. The user may need to enter data about several "Debtors", just like if you needed to show several different products on an invoice. For example the user may need to enter information about a husband and wife. This means two entries in the "Debtors" table. The table looks like so:
db_Debtors - DebtorId PK auto int, etc fields
The Third Step - Here's my problem. This step needs to make entries into a third table called "CaseDetails". Again, this is just like if you were creating an invoice with several different products on it, where you would want to get a subtotal of each product's cost. The table looks like so:
db_CaseDetails - CaseDeatailId PK auto int, CaseId int, DebtorId, int
* When this table is later viewed, It will reflect all "Debtors" attached to the specific "Case" being viewed.
The first two steps aren't a problem, I pretty well have that handled in the wizard. BUT How do I create the entries in the "CaseDetails" table when the user finishes?
My idea right now is..... Considering the "Debtors" will be re-used but only on rare occations, I'm thinking I should just add the "CaseId" that was created in step one, to the "Debtors" table at the same time the "Debtor" is created. So the table would look like so.
db_Debtors - DebtorId PK auto int, CaseId int, Name, Address, etc
I've a requirement where i need to pass some objects across the pages. So i created a custom class with all the properties required and created a instance of it and assigned all the properties appropriately. I then put that object in the session and took it the other page. The problem is that even when i set the properties values to the class it is coming as null. I set a breakpoint in the getter-setter and saw that the value itself is coming as null.
public class GetDataSetForReports
{
private Table m_aspTable;
private int m_reportID;
private string m_accountKey;
private string m_siteKey;
private string m_imUserName;
/// <summary>
/// Asp Table containing the filters
/// </summary>
public Table aspTable
{
get
{
return m_aspTable;
}
set
{
m_aspTable = aspTable;
}
}
/// <summary>
/// Report ID
/// </summary>
public int reportID
{
get
{
return m_reportID;
}
set
{
m_reportID = reportID;
}
}
/// <summary>
/// All the accounts selected
/// </summary>
public string accountKey
{
get
{
return m_accountKey;
}
set
{
m_accountKey = accountKey;
}
}
/// <summary>
/// All the sites selected
/// </summary>
public string siteKey
{
get
{
return m_siteKey;
}
set
{
m_siteKey = siteKey;
}
}
/// <summary>
/// Current User Name
/// </summary>
public string imUserName
{
get
{
return m_imUserName;
}
set
{
m_imUserName = imUserName;
}
}
}
This is how i'm creating an instance in the page1 and trying to get it in the page2. Page1 Code
//Add the objects to the GetDataSetForReports Class
GetDataSetForReports oGetDSForReports = new GetDataSetForReports();
oGetDSForReports.aspTable = aspTable;
oGetDSForReports.reportID = iReportID;
oGetDSForReports.accountKey = AccountKey;
oGetDSForReports.siteKey = Sitekey;
oGetDSForReports.imUserName = this.imUserName.ToString();
But the values are not getting set at all. The values are not passing to the class (to the setter) at all. Am i making any OOP blunder?
I'm trying to bind custom object to details view.
The problem is that enum property fields are not show.
Is there any way to show enum property fields in details view ?
I put some example code below (I do not specify any rows mappings, they are generated dynamically because different kind of objects are bound to details view):

I'd like to add some custom instance properties to an ASP.Net User object. for example, I'd like to log every user's login and have something like: User.LoginTimes or calculate the User Profile's Completion percentage and be able to access it like: User.ProfileInfoPercentage, etc.
Now What I'd like to know is what would be the best approach to do this?
Forget about user instances? (e.g. define a database table with userid and ProfilePercentage info and retrieve data from profile like: DB.GetProfilePercentage(Context.Current.User.UserID) )
Override the ASP.Net User class and add my own functionalities.
Use Extension methods for the user class.
I have some data displayed in GridView and there are multiple (repeat) entires.
There are about 20 rows of the same data, but I only want to display 1 row.
I know can amend PageSize="1" but then it shows multiple pages which I also don't want.
The multiple rows - are all of the exact same data - but it should only appear once!
I have an ASP.NET application that needs to remember some info about a user (and what company they are from) across pages, within a session. I imagine this is a requirement of just about any ASP.NET application of a certain size. I've used a few different approaches over the years. In the past, I've passed around an id in querystring parameters like so: [URL] and then instantiated the object on each page (from the database). Another common way of doing it is storing my objects in session variables:
Session["User"] = currentUser; // store at login
User currentUser = (User)Session["User"]; // retrieve on some other page
which saves a trip to the DB, but I worry about memory used if the User object is complex and the site has many concurrent users. I have recently inherited an application that uses public properties on the master page, like this:
Master.theUser = currentUser; // store at login
User currentUser = Master.theUser; // retrieve on some other page
This saves the cast, and looks more readable to me I think, but I don't know if it's better or worse performance-wise. It also has some logic in the getter where if the private value is null, it tries to get it from the Session variable, though I'm not sure if that's never used (or used every get!?) or what. My latest idea is to use my page class. I have a custom page class derived from the standard System.Web.UI.Page base class. It includes objects like CurrentUser as public properties. This seems to work OK. I like it even better. But I really don't know what's going on under the covers. Can anyone give an opinion on which approach is better and why?
Update: I've done some checking use trace.axd and Trace.Write and it looks like neither the masterpage version nor the custom page class version "remember" the values between pages. The "get" methods have a line of code that checks if the User property is null, and if so, reads it from the session variable. This happens when a page accesses the property (Master.User or the derived class's this.User) for the first time on a given page, then subsequent requests can get the value (without going to the session variable). So thus far the best solution looks something like this:
public class MyPage : System.Web.UI.Page
{
private User user;
public User User
{
get
{
if (user == null)
{
user = (User)HttpContext.Current.Session["CurrentUser"]; //check if session[CurrentUser] is null here and log them out if so?
}
return user;
}
set
{
user = value;
HttpContext.Current.Session["CurrentUser"] = value;
}
}
}
Then on any webpage.aspx.cs, you can do something like this: UsernameTextBox.Text = User.FullName;
I have a Company model and an Employee model and I want to create a Company and then create multiple employees for the company in one view.
How should I do this in the view?
And what should I do in the Create POST method to support this multi-entry view?
I am wondering how to handle and setup a means to submit multiple data entries via ASP.NET MVC.
Suppose I have a product database table such as: ProductId, ProductTitle, Price.
From the view, I was thinking to code the HTML form as:
<form ... >
<table>
<tr>
<th>ProductId</th>
<th>ProductTitle</th>.......
Suppose the form is to be submitted to Controller: Product, Action: Add. What sort of coding techniques can I use to handle this dynamic form, such that I follow good or best practice, and if possible also be elegant.
The solution I see so far is to test the Request.Form (or Formcollection) indexer/dictionary for existence for the dynamic input fields. E.g.
public ActionResult Add(Formcollection form)
{
int productEntry = 1;
string productPrefix = "Product";
while(true)
{........

I'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.
how am I be able to validate multiple entries (textbox control). It seems that using custom validate is not possible because each validator has one control to validate. In my case, I have to determine if at least one entry was filled with data.
View 4 RepliesI'm creating a shopping basket in ASP.NET using session variables to pass the data from a shopping.aspx page to basket.aspx, currently I have the pages passing the primary key of the product with a gridview on the basket.aspx used to display the data from the database.However this only works for one item at a time, how can I extended the session variable so multiple products can be added, as well as quantities etc?

I have made a composite control that has 1 Label Control ,1 TextBox ,1 button and 1 Panel Control. Below is my code:
namespace ServerControl1
{

AspNetHostingPermission(SecurityAction.Demand,[code]....
The above code compiles without any error. Also I can drag and drop this control from the Toolbox of my Project on my web form. However I am unable the change the value of my fromLabel control.It allows me to change the value in the properties window.But when I run the form it always shows me its default value which is "From". I want it to be flexible so that any one can change the value in the properties window.
I am trying to get the drop down list to only include table1 entries where table3.int1 is the current selection in another drop down list (table2.id). Example:
Table1: id, string1, int
Table2: id, string1, string2, dec
Table3: id, int1 (ref table2.id), int2 (ref table1.id)
Both drop down lists are inside of a FormView object for a asp.net page. My current select command(s) are having the DropDownList for Table1 display all Table3 entries, instead of just the ones Tied to Table2 id from the other DropDownList.

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.
