View 4 RepliesIn the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List);
In the Controller I build a viewModel with the data from this session
[Code]....
and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item.
[Code]....
When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList).
return View("view.ascx", viewModel);
When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.
I'm trying to add form data from an asp.net wizard into a session array object. The object should store the question number and question answer selected by the user for each question. I'm trying to use a multidimensional array to store the question number and the associated answer. I would also be open to using a hashtable or dictionary solution.This is the code I've got so far:
string[,] strQandA = new string[10, 2] {{"1", Q1.SelectedValue}, {"2", Q2.SelectedValue}, {"3", Q3.SelectedValue}, {"4", Q4.SelectedValue}, {"5", Q5.SelectedValue}, {"6", Q6.SelectedValue}, {"7", Q7.SelectedValue}, {"8",
What would be the most efficient way of storing a set of values in a session? I'm guessing it's either a List/Array or Dictionary. Basically, when a user selects an item from a DropDownList, a value (between 1 and N where N <= 20) is sent back to the server. I'd then like this value to be used as an index (if using arrays) or key (if using a dictionary) within the session. I don't want the value to be seen by the user, hence why it's not stored in the DDL. From what I gather, dictionaries are designed for key-lookups. However, since the scale is quite small, are there any overheads of using a dictionary that could make it less efficient in this case? Each corresponding value is unique to the user, so I've decided to use sessions.

im having some problems with jagged arrays stored in session for ASP.net i have some code which creates a jagged array, them populates, and then stores this populated jagged array into session
protected string[][] answersJArray;
answersJArray[0] = new string[4]("test","test1","test2","test3"};
answersJArray[1] = new string[4]("test","test1","test2","test3"};
Session.Add("answersJArray", answersJArray);
how would i loop through each jagged array in the session ?? if they were not in session i no i could do the following
for (j = 0; j < answersJArray[1].Length; j++)
{
label.Text = (answersJArray[1][j].ToString());
}
how would i do the above by looping through the session ??

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.
View 3 Repliesthe dropdown list is showing data from database, but how to retrieve the selected value and store it in a session variable??
View 1 RepliesMy problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
<sessionState mode="SQLServer" allowCustomSqlDatabase="true" cookieless="false" timeout="120" sqlCommandTimeout="30" compressionEnabled="true"
sqlConnectionString="Data Source=.SQLExpress;Initial Catalog=mytest;Persist Security Info=True;User ID=mytest;Password=mytest;"/>

View 4 RepliesI have a class called EditMapUtilities. Here are some class properties that I want to persist:
public class EditMapUtlities

public static Boolean isInitialEditMapPageLoad
{
get { return SessionHandler.isInitialEditMapPageLoad; }
set { SessionHandler.isInitialEditMapPageLoad = value; }
}
// REST OF CLASS NOT GERMAIN TO DISCUSSION AND OMITTED
}
Here is my SessionHandler Class following the pattern from this post Static Session Class and Multiple Users:
using System.Web.SessionState;
public static class SessionHandler
{
private static HttpSessionState currentSession
{
get
{
if (HttpContext.Current.Session == null)
throw new Exception("Session is not available in the current context.");
else
return HttpContext.Current.Session;
}
}
//A boolean type session variable
private static string _isInitialEditMapPageLoad = "EditMapInitialPageLoad";
public static bool isInitialEditMapPageLoad
{
get
{
if (currentSession[_isInitialEditMapPageLoad] == null)
return true;
else
return (Boolean)currentSession[_isInitialEditMapPageLoad];
}
set
{
currentSession[_isInitialEditMapPageLoad] = value;
}
}
}
I am still learning OOAD. I want to keep relevant properties with relevant classes. I also want to keep all Session stored variables in one place for ease of maintenance and to encapsulate the session keys and calls. I feel like my design is too coupled though. How can I make it more loosely coupled? Is my editMapUtilities class too tightly coupled to the SessionHandler class? How would you do it better?
