Asp.net Mvc - Session Variables Not Saving On Initial Page Load?

Mar 25, 2011

I have an MVC application which sets some session variables based on internal static IP addresses.I have built an ApplicationController to override the OnActionExecuted sub in MVC for data that I need to use throughout my application.However, the code below, which is just a snippet of my code but is edited for my post, only partially works. On initial page load, the session variables aren't saved, but after a page refresh they are. The issue I have is that these need to be saved on the initial page load.

If Session("Item1") = Nothing Then
If IpAddressShort <> "" Then
Dim locInfo = cmsRepository.GetInfoBasedOnLocation(IpAddressShort).SingleOrDefault()
If locInfo IsNot Nothing Then

[code]....

Theoretically, if I'm correct, if there is no Session("Item1") set/if Session("Item1") is empty, then the rest of the snippet should run and set those variables.How come this isn't setting those variables on the first time the page load?

Asp.net - Session Variables On An Intranet ASP/.NET Page?

Jul 8, 2010

I'm planning to use some session variables on an intranet ASP/VB.NET page, and want to make sure that I'm not missing out on anything important I should know, or that I have my information mixed up. So here's what I (think) I know about session variables.They:are stored on the server, so if I have a lot of users then they'll each be using some more memory which could lead to a slowdown.are inaccessible by the user unless I expose access. hang around/persist across user requests (i.e. each time the user makes a request from the page the data will still be there - until it times out). This also means that I need to make sure that the variable doens't have "left over" data in it.

Is there anything that I've got totally wrong, or anything I'm missing? I'd prefer not to get bitten by a bug down the road because I think I understand what's going on.

GridView - Using Session To Pass Variables From Page

Aug 3, 2011

I have a gridview and use a session to pass the variables from the page to an edit page. This works perfectly, until you search for a number. When you search the correct record displays in gridview, but when you click edit, it passes the wrong record.

Private Sub gridview1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~/~" & _
[Code] .....

I realize not all of the code is pasted in here, because it would take too much space. Any Ideas? I'm guessing it has something to do with e.NewEditIndex

VS 2008 - Variables Not Resetting During Page Load?

Aug 4, 2009

After the client finishes testing, they go to the results page and then my program returns them back to the secondary page.If they re-enter the testing page again, for a second go-around, with out completely leaving the program as I have been doing since I was tweaking the code after each run, the repetition counter is not resting back to Zero. It�s still retains the information from the previous testing phase.

Example:The client chooses how many testing cycles they want to go through, from 1 to the total amount available to them to test. Right now its only 5.When they first start testing, it starts at �1 of 5�, then progresses at one increment for each drug they test on. Once they reach 5 and answer their final question, the program then goes to the results page and then to back the secondary page. If they choose to re-enter the testing page without totally leaving the program, the testing page counter sits at �5 of 5�. Shouldn�t the page be resetting the variables each time it loads?

DatagridView - Initial Load Formating

Jul 5, 2011

I have a datagridview and need to do some formatting to it. On load the row 0 column 0 cell is highlighted. I need users to click on datagridview to select a value. The issue is with the initial load highlight it looks like the first row is already selected when in fact it is now. How can this highlight be disabled? Each row of has 7 cell, the user is able to select any of the cell of a row and the corresponding row ID is selected. The issue is that only that one cell is highlighted.

I would like the entire row highlighted regardless of what cell in that row is clicked on. One of the columns is a status value. I would like to color the text based on the value. For example if the Status is opened I want the text to be red, if the status is closed the text color should be default.

Asp.net - Using Session Variables In IE?

May 14, 2012

I have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.

Dim Rec_IDs As New List(Of String)
Rec_IDs = Session("Rec_IDs")
and
Dim Rec_IDs As New List(Of String)

Accessing Public Class Variables In Asp.net Without Session?

Feb 15, 2012

I am using this example I found to learn how to load class files and access variables through them. This is in a file called Class1.vb in the App_Code folder (this is not an app project):

Imports Microsoft.VisualBasic
Public Class my_class
Public Shared Sub my_sub()

[Code]....

How could I access the vartest variable without using a session, since if this is accessed by multiple functions at the same time the variable can be overwritten I assume. Is it possible to go the other way, where a variable is sent to a class file?

Asp.net - Session Variables Lost In A Specific Scenario?

Dec 23, 2009

I've got a problem losing session variables in an ASP/VB.NET application. The application allows searching for an item or it can show an item if provided with a unique link (in the browser). It holds information about the item in session variables. In the webpage showing an Item a user can click a button which opens a window with additional information about the item - obtained from a session variable. When I search for the item using the search engine and click the button - it works OK.

When I copy the link to a browser: the item is shown, however clicking the button returns a 'null exception' - the session variables with information about the item are lost. Moreover when I provide the link for the second time the button works, the variables are there!

Asp.net - Use Session Variables To Prevent Infinite Web Form Popups?

Apr 6, 2012

I have a web application that allows a user to view family members.

When the user clicks on a family member, it displays the member's basic info. There is also a grid displaying that family member's related family members. (e.g. User can click on the Father link. From that popup, they can then click on the Father's Father link, then click on the Father's Father's Grandson link, etc.).

To reduce the number of popups that appear on the screen, I want to prevent the user from continually clicking on family links past three members.

What is the best way to keep track on how many data forms have popped up? Or can this reliably be done with a web application?

SQL Server - Storing And Retrieving Session Variables During Login

Feb 20, 2009

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.

Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

Welcome Message To Display On Every Page Using Session?

Oct 12, 2011

Using a session variable in my VB.net site has been figured out just fine. I just need to get my welcome message to stay put on every page. I put the code and text box in my master page to allow the message to stay there, but my label with the user's name disappears when I click on a different page.

The session is still there because I have it set up to display the textbox to enter your code if the session is destroyed or not available for some reason.

my code is not allowing the First_Name and Last_Name of the user's session to show up? The problem is in the Page_Load but I thought I would throw in the whole master.vb file to show everything I have so far.

Why Is A Row Added To Session Datatable Disappearing On Refresh Of Page

Feb 25, 2010

I have set up a class as a facade to access the session variables for my app. In this app I store an entire dataset for a particular employer as a session variable.Within one of the sub pages I have a button that adds a row to an existing table stored in that dataset.

Dim curRow As Data.DataRow = mySession.tWorksiteOtherMeasures.NewRow()
curRow("lngWorksiteID") = getSelectedWorksiteID(getSelectedSiteID())
curRow("strMeasure") = ""
curRow("lngStatusID") = -1

[code]....

When in the code to add the row the row count increments and the row exists. Once out of that scope the page refreshes due to the button being contained in an updatePanel. When that happens and I click the add button again the row counts for that item reset to 0 and 1 after the code runs. The previous added row is gone.Here is how the Dataset is assigned from the web service:

Public Shared Sub loadDSEmployer(ByVal strUserId As String)
Dim myService As New someservice.service
mySession.dsEmployer = myService.GetEmployerAndSites(strUserId, isInternal)

Disable Page Cache To Force Page Load With Browser Back Button

'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()

When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.

Evaluated.LoadContainer.Load(Page Page, HtmlDocument HtmlDoc)?

Jan 5, 2011

I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.

When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.

[Code]...

IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.

Array Of Objects Also Saving Variables Of Class?

Dec 21, 2011

I have a small class of Object CellValue

Friend Class CellValue
Public CellColor As Color = Color.White
Public CellShape As Shape = Shape.Blank
Public CellName As String = ""
End Class

Then in my main I make an array of CellValue but I want to know if the values are also being passed down with the array.

Dim Plan(SizeW - 1, SizeH - 1) As CellValue
Dim CellW As Integer = PictureBox1.Width \ SizeW
Dim CellH As Integer = PictureBox1.Height \ SizeH

[Code].....

Are CellName, CellShape and CellColor being tied to each element in the array?. The reason is because I need to use these properties to tie certain functions to them. The CellName should have a MachineID which I would have to use to pull some info from a Database.

The Array should also be serialized and deserialized to XML as customer needs to create/edit and delete certain values in the array. And in order to save the array has to be in XML

So the Questions are does it save the CellName, CellShape and CellColor for each element, will it be affected if I serialize and deserialize using XML. If possible, how can I call up the Cellname p.e for a specific array element.

.....

//Saving changes set 2
e = a;
f = b;
g = c;

without having to type everything out...A technique using EXCEL or Notepad....Find and Replace. This would save a lot of time coding and becomes pain in the butt when you working with many variables.

Saving Multiple Variables Of A Type To Be Loaded Later?

Jun 12, 2011

<pre-question blab>// skip if you want Might as well consider me new, as I haven't programmed in years, and that was only tinkering in Java. Trying to get back on track a bit, so starting with VB to get the feel going to continue learning. I don't mind putting in the effort to learn and look up, I just am not 100% sure what I should be looking into at the moment... Old programming I did was nothing advanced, only little things like calculators, notepad-esque writers, and that sort.</pre-question blab>

I'm BASICally wanting to know what I should look into for saving multiple variables of a custom class object to be loaded later. I've seen some things about text, and I can do that fine, but don't think it would be the proper/best way of handling things
at all. I also saw some talk of XML, SQL tables, etc. I just need a point in the right direction.

For a bit more info on my actual project, I was tinkering with a 'simple' program to allow users to create rooms/objects/etc., which will then be converted into Inform 7 language (an interactive-fiction language).The variables needing stored are objects with a number of string variables and integer variables. I need to be able to save those, then load them out later into an array of said objects.

For anyone needing a more VISUAL image of what I mean, here are a few screenshots to show you what I mean. Also, if anyone has ever used Adrift, it is (at the moment) very similar to it, but for the Inform language.
