Web Forms :: Variables From Page To Page?
Apr 9, 2010
On my current project I need to pass a variable from a page to another one.I do not have particular problems with that part of the code but my question is more orientated towards the practicality. I want to make sure everything is fine and the user redirect to a "default" page with an error message if it fails.
Page 1 asks the user for some information, on submit the data is stored in the DB and the Index of the row inserted is passed to a second page using a Session variable. What I'd like to do is check the variable on Page 2 and make sure it is fine. If the Id is missing or incorrect I would like to redirect to the error page. But what is the best way of doing so?
At the moment I have this code on the Page_Load of Page2: [Code]....
In the error page I display an error message if the Session["ERROR_MSG"] is set. I basically need to know if this is the right way of doing this kind of check. Is it OK to put it in the Page_Load? Should I use Page_Init?

I need to access a variable that is declared in a master page to a child page. I'm using asp.net 2.0 (vb). I'm sure this should be easy and is down to my inexperience with asp.net! A rough guide to my code is below;
MASTER PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<script runat="server">
Public UserNumber As Integer = 3
End Sub
</script>
CHILD PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>

VS2010/VB/ASP.NET 4.0 If an error occurs in an ASP app you can redirect it to a default page which is defined in the web.config file How can you pass the variables (URL) to the error webpage then to a logfile or sent via an e-mail address?
Example: 404 Error
- Page hosting the link
- URL
- Search (if applicable)

I am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.
Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");
which takes it to the Data Entry page where user updates the information and save the data.
The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.

I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.
Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.
This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.

I have a web application that contains a MasterPage and a Web.sitemap file for the navigation. I am loading the navigation into an <asp:Repeater> control and I associating it with <asp:LinkButton>; something like this:
[Code]....
I have two issues:
Setting Session Variables: I'd like to set some session variables when any menu item is clicked.Dynamic Url: Once the Session variables are set, I'd like to set the url dynamically after the Session variable is set The thing is, I'd like to use the same aspx file for two different menu items, and I'd also like to set some session variables at the time of menu selection. I am aware that I cannot use the same url when I define the url in the web.sitemap file.

I have some code I only want to execute the first time I display a form. With this in mind I created a class variable which I initialize the first time I execute page load.
public partial class CLVideoDefinition : System.Web.UI.Page
{
string videofile;
string first;
protected void Page_Load(object sender, EventArgs e)
{
if (first != "N")
{
I then select a value from a drop down list , but when it does the auto postback it executes page load but my class varaible has been reinitialized to null and will then execute the code I only want to execute on the first run. why my class variable has been reinitialized.

I have a Master Page which controls the styling of my site. In the Code Behind, there are a few class instances instantiated as well as variables. These classes validate user access and then create user objects
I have a few Web Content Forms which carries out instructions based on the user objects. So far it seems that on each Web Content Form I have to create new instances of the classes found on the Master Page. This is doubling my work for every Web Content Form.
Is there anyway I can inhereit Classes and objects instantiated in the Master Page Code Behind?

I have gotten alot of help lately on my project and think I only have one more issue that I can't think of how to do. What i'd like to do is pass a login name and password from a Login.asp page to all of my other pages. So for instance if I have a successful login, I am taken to the Home.asp page. But i'm not sure how I can pass the LoginID used from Login.asp to the Home page. Ideally i'd like to use this information in the SQL connection strings, and to customize the Home page to show orders assigned to certain people that are logged in.

I'm trying to convert a game I made (WindowsFormApplication) to an ASP.NET page.
My Problem is that I have a lot "private" variables in my WindowFormApplication and those variables are important for the game. But when after I Declare all my variables (in my Page_Load), they turn null no matter what I do(click a button, refresh the page).
Is there anyway to save my variables between buttons (other than Session, because I'd have to create like 6 more sessions)

I know there are at least 2 ways to send Variables to another ASPX page.
The first way is the use <form> and <input type="hidden">
The second way is the put the variable(s) in the URL such as http://www.joesmith.com/Sample.aspx?var1=bob&var2=cunningham
Is there a 3rd way to send variables using VBScript inside the <script runat="server"> tag?

I am using C#.
I am having below code in C#:
protected override void OnInit(EventArgs e)
{
try
{
if (Session["boolSignOn"].ToString() == "true".ToString())
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
else
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
}
catch (Exception ex)
{
Logger.Error("Error processing request:" + ex.Message);
}
}
protected override void OnLoad(EventArgs e)
{
try
{
if (!string.IsNullOrEmpty(Session["panelOpen"].ToString()))
{
lblPanelOpen.Text = string.Empty;
Session.Remove("panelOpen");
}
}
catch (Exception ex)
{
Logger.Error("Unable to remove the session variable:" + ex.Message);
}
}
In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.

I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?
Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?

I'm trying to set session variables in one page, and retrieve them in my code file in the page that it posts to.
I keep getting this error. I put the correct namespaces in, and enabledSessionState = true to my application files, but no luck.
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I'm just calling a session variable, and I get that error
e.g,
Public AUID As Integer = Convert.ToInt16(Session("AUID"))
