How to know whether the close button on browser has been clicked

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net

Hi All,

 I want to perform some session and application related activities on server side, when the close button of browser is clicked.


1. I have handled it using 'OnBeforeUnload' in body tag of master page

2. but it is getting fired for even if the end user navigates to other page.

3. so my requirement is to call the code on server side, only iff, the close button of the browser is clicked.

Thanks in Advance..


Hi guys,

This is still unsolved problem. Because according to mudassarkhan, if i apply his solution, then everything is ok.

but when the page is regreshed, the value of clicked variable becomes false and undesired action happens once again.

Please come with some solution..guys..

Creating a "Save Button" in a browser based Form

I'm not sure if I'm missing something obvious, but I need to have the funtionality of the "Save Button", which is available and works on the tool bar, available in the form...and I can't seem figure out how to do it.I've found examples, in this forum, of how to use the "Submit Button" to act as the "Save Button", which did work for me, but only when specific basic criteria was met.The criteria that I now have is that I'm initiating a workflow to automatically start when a new item is created.  My workflow then moves the form to one of a few possible different form libraries, based on the logic in my workflow.  The different form libraries are to manage different teams of people that would have access to the Form and then that team would process the form accordingly.My specific situation: 1 - User opens a new form (works) 2 - User enters data and then submits the new form (works) 3 - Workflow is initiated and the form is moved to another form library to be worked on by a select group of people (works) 4 - The form is opened and reviewed and some changes are made to the form data by the select group of people (works) 5 - The form data in the form libary is updated (works, but only if the save button is pressed in the tool bar and then manually closes t

Web Form breaks after using the browser's back button

I have a web form that allows a user to put some data in a textbox and click a button to do a search on that data.  It opens up a Sql Server Reporting Services report using the data they entered on the previous page.  If they use the browser's back button to go back and enter some different criteria to search on, the buttons don't work anymore. Any ideas or suggestions on what would cause this?   Thanks!

Disable a link button in grid view after it is clicked

I have a grid view with each row as a link button. When I click on the row, some data parsing process takes place (about a 15 sec process). The grid refreshes itself at a regular interval. I want to disable the link when it is clicked once, so that the user gets to know that row has been processed already and does not click it again, until the grid refreshes itself and the row disappears. I am copying my gridview code below. Please give me some idea on how to disable the link button on that row as soon as it is clicked.Thank You. <td rowspan = "4" valign = "top" > <asp:Label ID="gvOrdersQueueLabel" runat="server" ></asp:Label><br /> <asp:UpdatePanel runat="server" ID="updatePane1"> <ContentTemplate> <asp:GridView ID="gvOrdersQueue" runat="server" OnRowCommand = "ParseOrderMessage" EmptyDataText="No Cases Found" BorderStyle = "Double" AlternatingRowStyle-BackColor="Beige" EnableViewState="false" AutoGenerateColumns="False" HeaderStyle-Height = "20" RowStyle-Height = "20" AllowPaging ="true" PageSize = "20" OnPageIndexChanging="gridView_PageIndexC

Browser back button issue when ViewState stored in DB.

I implemented the solution of storing the ViewState in DB (since we were getting lots of Invalid & Corrupt Viewstate errors on our site daily) as given in the following website:http://weblogs.asp.net/adweigert/archive/2004/03/09/86628.aspxThe solution was implemented in one of the aspx pages on our site that behaves like a wizard (not using the wizard control though). After starting to store the viewstate in DB, the Invalid ViewState errors were eliminated completely, but I am now facing the following problem:1) User selects radiobutton1 of the two radiobutton choices on Page 2 of the wizard, a postback happens which displays some extra information on the page based on the selection. Now the user hits the next button on the page that also does a postback & displays Page 3.2) On Page 3, user hits the "back button" of the browser instead of the "previous page" button that is available on that page.3) This displays Page 2 from cache in original state(without any selections made). When user now selects radiobutton2, a postback is supposed to happen, but it does not. User then clicks "next" button on Page 2 (a postback does happen here however), & Page 3 is displayed, but it still thinks that radiobutton1 was selected (the original selection that was made in step1) on the previous page & hence displays information accordingly.I am assumi

Mobile redirect and the browser back button

Has anyone here ever successfully constructed a two-page mobile website with VB, one page for input and one page for displaying results?  If so, how do you call the results page and can you return to the input page using the back button on your mobile browser?  I have no problem creating such a website for regular browsers, but I simply cannot construct one for the iPhone or the Droid ... you can't return to the first page via the backbutton and still have it be functional; all you have is the graphics.  There is no load event for the page you're returning to.  It seems like mobile browsers don't handle server-side redirects properly.  If you open a new page via a hyperlink, you can return to the page you were on and it will still be functional; not so following a redirect to another page on your site. I've experimented endlessly with cache settings, redirect parameters, and the pagestatepersister class to no avail.  I need to know if I'm on a futile quest.  Can anyone offer confirmation for can do/can't do?
