View 1 RepliesI am using a datagridview. I am using a command field & want to pass a session id (which is stored in database) from one page to another as I click on the command field link.
View 2 RepliesI have a report parameter page which contains many pop up windows for the parameter selection. For example, for driver , there is a pop up window called driver.aspx which contains a listbox that contains list of driver's name.
Now, for each of these pop up windows, i am passing the values of these windows as a session value.
Now, when a user logs in the system, there are many parameter pages for different reports which commonly share the same pop up windows if the parameters are same for different reports.
The problem now is,a user selects 10 drivers for report 1 and runs it. When he goes to report 2 and runs the report, the report 2 takes only those 10 drivers as the driver parameter value.
It means, the error can arise on the system because he may forgot that he have selected 10 drivers for previous report 1. User will not have time to recheck each previous selected values of different paramaters.
What i want is, when a person moves from one report page to another, i want to clear all the session values and adjust it as default for the new report .
im passing gridview row value to next page using linkbutton with session.But i got this error "Unable to cast object of type 'System.Web. UI.WebControls. GridView' to type 'System.Web.UI.WebControls.LinkButton'." and my code is
PAGE 1
Protected Sub gridview1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gridview1.RowCommand
Dim RefNo As String Dim LnkRefNo As LinkButton
LnkRefNo = e.CommandSource
RefNo = Convert.ToString(LnkRefNo.ToolTip.ToString())
Session("ref") = RefNo.ToString()
Response.Redirect("update.aspx")end sub
PAGE 2
textbox1.Text = Convert.ToString(Session("ref"))
My doc isn't coming up in the url on the next page so the gridview isn't appearing. What am I doing wrong?

View 1 RepliesI'm working on a solution to part of my companys site that is done in 2 different languages. My part of the project is in ASP.NET, and the login portal is in a different language. We pass authentication credentials by storing login information in the database on the portal page and then sending a corresponding token to the URL in the page written in .NET. Almost all the tutorials and articles I've read about security for ASP.NET, and most languages, the message has generally been "just use the built in stuff and don't mess with it".
I have code that takes the token, goes into the database and gets the user details.. what do I do then to integrate that into the built-in security stuff for ASP.NET? I'd like to ultimately use Action Filters for authorization on my controllers.
I wrote a page Page method in my aspx page. in web service method I need to call FindControl method return textbox and get text box value. But my findControl will take MasterPage object to iterate.
code.<script type = "text/javascript">
function ShowCurrentDateTime() {
$.ajax({ [code]....
But I am getting compiler error when use Page.Master: Reference to non-shared member requires an object reference
How to pass Master Page object or Page to Page method?. So I can use in Sared method.Is there any way I can access Textbox value directly in Page method? I need access couple of controls in Page Method.
I'm writing up a security document and it would be great if programmers in other languages than PHP could chime in on (perhaps the default) way sessions are passed by URL in their language's default session handler.
eg. PHPSESSION=token in PHP
Oh, and if yes does it also use cookies?
I've two application ASP.NET (once is Mojo Portal). I can navigate from one to other using an URL token id.
To this way, by token, I create a new session and save the relative auth cookie.
But, sometimes, the asp web application don't keep the session and put me down. When this happen I can't login until the session cookies is not deleted.
Both the two application are behind an reverse proxy.
In our application, we have a need for a user to "impersonate" a different user. Think of it as a hierarchy -- Bob is above Frank in a hierarchy. Bob is logged in, and he needs to do things in the system for a short time as Frank. So, we have given Bob a list of users that report to him, and an impersonate link. He clicks on this link, and, behind the scenes, I log Bob out, and log in as Frank. I also set a session variable that tells me that really Bob is they guy who is the user. Also, Bob (acting as Frank now) has a nice little link at the top of every page that says "Stop Impersonation."
In addition, when Bob is impersonating Frank, Bob is restricted from doing some things, like changing Frank's password.
This was working great, until we encountered a situation where, if the session (I think -- getting confused here) gets destroyed (such as when I copy up new code and dlls to the live site), then when Bob clicks on "Stop Impersonation" he gets redirected to the default page, and is still logged in as Frank, but without the Impersonation session variable. So, now Bob really is logged in as Frank, and can change Frank's password (among other things).
How is it that a session variable (Impersonation) gets destroyed, but I guess the session is still hanging around, because it doesn't make the user log in again?
This is a somewhat serious bug for how our system works (bug in our code, I'm sure, not in .Net). We are using ASP.Net c#, aspnet membership services, .net 3.5, forms auth...not sure what else you need to know.
EDIT: Updated information. Looks like when "something" happens, for instance, when I recompile some dlls and copy them to the webserver, the session gets dumped. Or, rather, the variables in the session get dumped. The session id stays the same. I do get to check for Session.IsNewSession and it returns true, even though the id is the same as it was before.
Just like Utaal mentioned, Membership Services is separate from Session, so it's forms auth token is still hanging around in the browser, but my session variable telling me that that isn't really the user who is controlling the browser isn't there anymore.
EDIT: Sky, here is what I'm doing to authenticate a user. I can't figure out where I would insert a ticket into this flow:
if (Membership.ValidateUser(txtUserName.Text, txtPassword.Text))
FormsAuthentication.SetAuthCookie(txtUserName.Text, false);

how to pass value in GridView from Page1.aspx to Page2.aspx
In the GridView, I add one column that have CheckBox and the GridView have 5 rows then it will be 5 CheckBox.
What I would like to do is, when we checked 3 CheckBox from the GridView and click submit button, it will go to the Page2.aspx and display back the GridView but only display 3 rows that had been checked from the Page1.aspx I'm using VB
My application is simple, I have 2 pages:
RSSProducer.aspx: A page that generates RSS (XML) feeds
RssConsumer.aspx: A page that retrieves the RSS feeds and displays it to the user in a repeater control. To do this I am using the System.Xml.XmlTextReader to fill a DataSet with tables based on the RSS-XML retrieved from the RSSProducePage. A table within the DataSet is bound to the repeater control.
For example, this is what I have in my RssConsumer.aspx page:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Session("permittedToViewSomeDetail") = True
Dim url = "http://localhost/DevSite/RSSProducer.aspx"
Dim reader As New System.Xml.XmlTextReader(url)
Dim ds As New DataSet()
ds.ReadXml(reader)
myRssRepeater.DataSource = ds.Tables(2)
myRssRepeater.DataBind()
End Sub
My problem is that user-authorization details are stored in Session in the RssConsumer page that need to be accessed in the RSSProducer page (in this example it would be Session("permittedToViewSomeDetail") that I need to access in the RSSProducer page); however, the Session identifier is not common between the two. This means that I cannot access the authorization details in the RSSProducer page.
The reason for why is fairly clear to me:
User's browser makes a request to the RssConsumer page Server generates a Session ID (which is stored in a cookie) if there is no existing Session Identifer The RSSConsumer requests the RSSProducer page...which generates a new Session ID every time because no session identifier is ever going to be found.
I tried using cookieless session so that I could pass the SessionID via the URL to the RSSProducer page as an experiment but for some reason the XmlTextReader doesn't work well with this method (but the desired shared session does work). I've hit a brick wall here. Does anyone know how to share session between pages when one page makes a request to the other?
in my webpage pass values from one page to another page Querystring
