I want to sign out a user when his session times out. So used following code in Global.asax:
protected void Session_End(object sender, EventArgs e)
{
FormsAuthentication.SignOut();
}
But seems session_end never fires. Any idea how can fix it? I'm using ASP.NET with default settings.
I am using Httphandler to access my pages. Have Loginstatus Control on the master pages.
OnLoggingOut for the Loginstatus control I am doing a Session.abandon()... But My session_end
does not get called in the Gobal.asax.I tried link button and everything. but when I take out the httphandler the Session_end gets executed in global.asax
I can handle the full session end on my own but is there any way to call Session_end in global.asax?
I'm creating web application behind load balancer. To this moment I configured it to store session in database but I'm not sure how should I handle session expiration. The problem is not sessions are not removed from database but Session_End event because I have to call some web service method in it.
Assuming Session_End is called when expires the thing I'm afraid of is situation when session is created on one server but finished on another. In this case I'm afraid Session_End on first server will be executed prematurely and I will call web service too early. What would you suggest in this situation?
Edit:
I remember some time ago reading about Sql Agent reacting to session end event and then performing custom code. Can anybody confirm that this solution is possible?
in my web app users login to website normally and they have tagged in user table in database as online user in Session_End i want to log them outIn Session_End i have no access to HttpContext.Current.Session or Session only they are both null how can i access to session variable at (Session_End) event.
View 1 RepliesI've some doubts on sessions in asp.net. If the client send a first request to a website then in response the site sends a sessionId which will be stored in browser as a sessioncookie upto this point its clear for me. If the same client sends the second request the session ID should send to the server to idetify the user.my question is How this will be send to the server?
second question: why not the session_End event won't get fired if the session mode is OUTProc??if i want to execute some code when session ends where can i put that code??
i'm using asp.net 2.0.
there's a way to add an handler to manage the session_end event without using the global.asax?
(i can't modify my httpapplication code so i need to add the handler externally to it)
I have an asp.net 4.0 application that is using forms authentication set to a timeout at 45 minutes. I would like to redirect the user to a timeout page when the session has expired. Can anyone tell me how to do this? I am running .net 4.0.
web.config has:
<authentication mode="Forms">
<forms name=".ASPXAUTH" loginUrl="~/Login.aspx"
defaultUrl="~/Default.aspx" protection="All" timeout="45"
requireSSL="false">
</forms>
</authentication>
Global.asax.cs file has:
void Session_End(object sender, EventArgs e)
{
Response.Redirect("~/Timeout.aspx");
}
Why Session_End event occurs only in "InProc" mode not in "State Server" and "Sql Server"?

Can I fire a custom event in asp.net according to my needs ?
I am making a simple chat application for my website.
I am using cache variable to store my chat. When I submit my textbox cache variable updates and text is cache variable is displayed to both the users. Since , I get a postback , my page refreshes and I get an updated value of cache variable but the other user needs to refresh the page.
So, is there any method, which can check if cache variable has been updated and fire an event , so that , I can deliberately force the browser to refresh.
One more problem , I am want to list the online users of my website. ( I need to list all sessions currently active ).
I think , best possible way is to insert current date, time on database after every 10 seconds by all users. How can I get an event which can update a column of database every 10 seconds ?

I have to establish an HttpListener that will wait for requests made by our client's server. I have to receive that request on port 8088 and extract the query string. That is the easy part. I'm running the HttpListener in a windows service. I cannot get it to fire properly. I build the setup project install the service on our server and it never starts.

View 1 RepliesI have a form with several text boxes on it. I only want to accept floats, but it is likely that users will enter a dollar sign. I'm using the following code to remove dollar signs and validate the content:
jQuery:
$("#<%= tb.ClientID %>").change(function() {
var ctrl = $("#<%= tb.ClientID %>");
ctrl.val(ctrl.val().replace('$',''))
});
asp.net validation:
<asp:CompareValidator ID="CompareValidator4" runat="server" Type="Double" ControlToValidate="tb" Operator="DataTypeCheck" ValidationGroup="vld_Page" ErrorMessage="Some error" />
My problem is that when someone enters a dollar sign in the TextBox "tb" and changes focus the validation happens first and THEN the jQuery removes the dollar sign. Is it possible to have the jQuery run first or to force the validation to run again after the jQuery executes?

View 2 RepliesI have an image on my page than can be changed from a fileupload asp.net control on the page, i want to provide and alternative to clicking the button by allowing the user to click their image. i gave the fileupload a class 'jqueryPhotoUploadTrigger' and it renders like this:
<input type="file" name="ctl00$ctl00$ctl00$ContentPlaceHolderDefault$C2kMasterPlaceholder$ucEditDetails_20$photoupload" id="ctl00_ctl00_ctl00_ContentPlaceHolderDefault_C2kMasterPlaceholder_ucEditDetails_20_photoupload" class="jqueryPhotoUploadTrigger" />
i then have jquery script at the bottom:
$(document).ready(function() {
$("#clickMyColl").click(function () {
alert("image has been clicked");
$('.jqueryPhotoUploadTrigger').click();
});
});
the alert does show so i know the script is firing when i click the image. i was just hoping the .click would fire the event on the button but it didnt. can i do it this way or must i find an alternative?

I noticed on a number of formviews that my validation controls seemed to be firing twice (which they were). I just found a case where a "Save" button had
onclick="UpdateButton_Click" in its defintion on the aspx page as well as the event routine having a "Handles UpdateButton.Click." This scenario made the UpdateButton_Click code run twice (and thus I expect that any validation controls would fire twice as well). When I removed the onclick="UpdateButton_Click"from the button defintion, the code only ran once, as desired. This double validation has gotten me especially with customvalidators.
Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
<my code>
End Sub
The question now is, why does having the onclick defined as well as the "Handles" on the event routine cause a double run of the event routine?I am going back into all my code to find where I have this "double" hit and remove the onclick in those instances.
