I need to store data from a form for recovery from the session.
Below is my rough first attempt for a generalized method for textboxes:
Load Session:
[code]....
However, it appears that the Controls collection is not working for me. What am I doing wrong?
this.Controls.OfType<TextBox>() yields no results at run time when I do a quick watch on it.
I am using Visual Studio 2008.
I created a New Project ASP.NET Web Application.
I created a Textbox named VisitorName. The visitor puts in their name and it goes in VisitorName.Text
There is a Label that says "Which do you own?"
There is a RadioButtonList. It has Cat, Dog and None.
There is a button that says Add to list.
The button needs to add the results of the above items and put them in the list.
Now you keep adding people and their pets.
Once there are all entered you press send and I get the results for everyone entered during that session via email.
I have no database access and the information does not need to be stored in such a way.
I would like to use a datatable or datalist or something to that sort.
Oh and I would like the visitor to be able to click on a name in the table and edit the data using the form controls not in the datalist or datatable itself.
Its related to datatable in gridview store in session and then session retrive and store to database. basically i am using gridview here creating new row for button click and these row adding untill user's last entry then submit all these entry to database. so i want to use session variable to store this data temporarily and after final entry user click on submit button and all data shold be save in db.

I'm am building an web application that needs to be able to scale.We want to store, an connection string, an object that says what organization the user is working on right now and the identity of the user.
We could serialize down this and send through the userdata property in the FormsAuthenticationTicket, but that feels to not be the optimal solution, cause its is 4-5 strings of data that is unncessesary, but the main issue is that we are sending an encrypted connectionstring to the user which we dosent want to.
So what are our options?Can ASP.NET Cache be our solution?, can we couple the expiration of the asp.net cache and the formsauthenticationcookie?

View 1 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?
I have a DataTable with about 10,000 rows in it.
I would like to store this data once for aspx page. When the user selects different options in the page, data is further selected from the already stored DataTable.
I tried using the ViewState, but as soon as the data grows beyond 100 rows, performance degrades.

View 2 RepliesCurrently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.
View 11 RepliesWhen the user logs in, I want to store his userID in the session with
HttpContext.Current.Session["UserID"] = 2354; (this is just a hard-coded example)
Then, when I run a page method, if I do
var test = HttpContext.Current.Session["UserID"];
will the variable test hold the value I stored when he logged in?
If this is a correct way of doing it, how do I access the session when I receive a call from a page method? I want to put the test =... line in a page method to identify which user the request is coming from.
