Except session and viewstate or a control with a value (including sqldatasource).Is there a way to store the value(s) in an object that will not loose the value if the page refresh?And also the best practice to hold sensitive value? I'm using viewstate with encryption for now but if p.e., have to hold a dataset then the page size will rise dramatically.
View 23 RepliesI would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.
In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.
This table contains some business flags on its 0th, 1st, 2nd columns.
I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.
I'm currently creating a Class Library for DTOs and was wondering if I should store an ID or an Object

Prior to using a ViewModel, I could easily pass the "soon to be edited" object directly to the view without needing to fuss over setting individual properties etc as the View conveniently accepted the Employee type directly..
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(SomeEmployee);
But now I'm using a ViewModel with DataAnnotations attributes applied over the top of various properties for validation purposes. Which creates a problem.. After fetching the "soon to be edited" object from the db, setting the ViewModel's values is suddenly a whole lot more complicated. I can't simply pass the retrieved object straight to the view, as the View now expects the VMEmployee type instead. I would like to be able to do something like:
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(new VMEmployee(SomeEmployee));
All paths seem to lead to a huge constructor which manually sets the values of each individual property. But I never had to do that before when I wasn't using a ViewModel. Model binding was a blessing! My objects also have complex child objects, which my form is also collecting values for, so this would be a huge/verbose task against DRY principals. I don't even really want to use a ViewModel, but am forced to because I need two different DataAnnotations rule sets for different validation scenarios applied to the same object.
All I want to do is be able to have two different DataAnnotations rule sets for different scenarios. I.e. public-facing www site vs internal-facing admin site. DataAnnotations doesn't seem to be flexible enough to easily cater for this common need. I've tried AutoMapper, but it throws an error saying it can't map my object types, I suspect because Employee was auto-generated by LINQ to SQL. What is the most elegant way to achieve this while sticking to DRY principals?
Does the DateTime object stores the CultureInfo with it, or you need to use the Formatter to format the DateTime according to current culture ?
I have a class property that retuns a DateTime. Within that property I am setting the DateTime object with current culture information using CultureInfo object. Below is the code for class property I am using:
public DateTime PrintedQuoteDate {
get{
DateTime printQuoteDate = DateTime.Today;
// cInfo = CultureInfo object
return Convert.ToDateTime(printQuoteDate , cInfo);
}
}
So my question is when I will use the above property in my code, will it have the corrosponding culture information that I am setting in its get method, or I will have to use the same CONVERT code for formatting date time. The restriction here is that the Property should return only DateTime type.

In Web Forms I stored a lightweight User object in the Session Variable.
[Code]....
Then whenever I needed the full force of a user object I would ask my repository to return me the User object that matched (be it from the database or cache).
Where do I store my LightWeightUser object for the session's user in MVC, I see I still have access to Session, but is there a better place?

View 3 Repliesconsider this scenario: a user on my website has a profileID. There are some pluginID's associated with this profileID.
E.g.: User1 might have 2, 3 and 5 plugins associated with his profile.
When the user logs in, I store the profileID of the user in a session variable cod. ON a certain page, the user tries to edit the plugins associated with his profile. So, on that page, I have to retrieve those pluginID's from the DB.
I have applied this code but this fetches only the maximum pluginID from the DB and not all the pluginID's.

I was trying to figure out how can I store multiple pluginID's in this session variable?
