I need to save a value to a session variable from a javascript function, and then be able to call this value back from the Session into another javascript function during post back.
How do you do this?
Currently 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.

I had a .net 4.0 vb.net page that was setting session variable and setting a hidden form value to the same value. It was a paypal buy now button. When the user selects it, they are sent to paypal for payment. If the transaction is good, they are redirected back to another page on my site and a hidden value is sent back with the invoice I originally sent them. They are sending the form value, but my session variable does not available.
From the user point of view it's all seamless.. Is it the same session? And should my session variable be available?

View 5 RepliesI am building a simple search interface for one of our existing systems. I am using windows authentication. What I would like to do is grab the username of the logged in user via httpcontext.current.user into a session variable on page load and use it in various places on my page. My problem is that when i run my code in debug mode from visual studio it works fine. But when i try to run my code from the browser using localhost it does not work.
View 4 Repliesit possible to use an application event to save the username in a session variable? I would like to do something like this:
private void ContextOnBeginRequest(object sender, EventArgs eventArgs){

}
However in the above code I get an error saying that Session state is not available.
I am using the ajax control toolkit tabcontainer with 5 tab panels inside of it. Each tab contains areas where one must input information. The page also contains add, edit, and delete buttons with gridviews above them. What I am trying to do is to make the user save or cancel changes when they change the activetab. I am using a javascript confirm box but I need to try to retrieve the value of what is pressed from the javascript box to decide whether to discard the changes or stay on the page and make the user finish the input. Is there any way to save the value from the javascript box into a variable so or must i try something else?
PS I wasnt sure whether to post this in the javascript section or the asp.net section since im using asp.net with c#.This is kinda what im using but would like to turn it into a confirm box and pull the true or false value.
protected void TabContainerContent_ActiveTabChanged(object sender, EventArgs e)

View 3 RepliesFor my current project I am using form authentication.What occasionally will happen is a user will timeout (unbeknownst to them),they try navigating to a different page (call it Page B) and they get kicked back to the login screen.This is fine and I have no problems with this.
However,after they enter their credentials and are authenticated they are redirected back to "Page B" and an error is produced because a session variable wasn't loaded. This is due to the fact that they were redirected to "Page B" instead of the page they would normally hit after a login (call it Page A).Is there anyway to force the user to go to Page A instead of Page B in these situation to avoid these errors?
I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
What would be the proper syntax in ASP.NEt 3.5 C# to assign a TextBox value to a temporary or session variable to be manipulated (added, subtracted, multiplied, divided) at different points in the application? I want to add a decimal number to this variable in almost every instance as well.
View 3 RepliesI have the dataset. in this i am having total 20 tables with huge amount of data..I want use this data over all the page..so where i can keep this data..
before i used viewstate but the viewstate data is render to page every postback ..so this time the page size is increasing(interanlly viewstate is rendered to page)..so performence wise it was very slow..
Now i change my logic insted of viewstate to i used Globel Dataset on Page Level.. now the performence wise better than viewstate..
i used Like shared dsControls as Dataset at top of the page..so every time i use this dataset..
my quesation is session is better or Globel variable is better way use in my situavation..
I have one AsyncFileUpload control ,one Attach button,one Listbox and Save button.
When Users browse the file and click the attach button, filename must be added to listbox. So in this way the user has the option to add upto multiple filenames to listbox. For this i have written the following code

this is source code

In Attach button click event i added the filename to listbox and saved the Asyncfileupload controls in different session variable.
When user clicks on save button all files has to be saved in application folder and for this i wrote the following code.

But iam unable to save all the files . Suppose i added two AsyncFileupload controls to session variables, only last file i,e. 2nd file can only be saved and couldn't get first file.

I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?
I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page

I have some code in my page load event where I just want to fire once when the user opens the Browser. The only issue is if you open a new tab with the same website the session variable does not reset. Is there a way to reset the session variable when you open a new tab or do you have to take the whole web browser down for it to clear the session variable.

I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.
I have some cascading dropdownlists using the ajax toolkit I have a set up datatables in an xsd file. Then use these in a webservice to populate all the fields ... this all works great but now i need to pass an additional paramter to the first dropdownlist ( a date) but don't know how to do this? The method is below...
[Code]....
The other code is:
[Code]....
The first change would be to the tableadapter to add a param to the code i.e
AuditWebDS.TeamsDataTable teams = teamsAdapter.GetTeams(calldate);
but how do i get the calldate param to the webservice method... i tried a session variable but it comes up with session is null ? Is there another better way?

View 9 RepliesI have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.
