I have a web page with a button. When I press the button something happens (it doesn't matter what). What I want to do is: when I close the browser (the page is closing, too) I want to call the button1_click event. How can I do that?

how to circulate the running of the codes after opening the page once and closing it soon
My default page has a usercontrol that opens up a modal to allow updates. When the user closes the modal window I want the usercontrol that resides on the default page to update.
it looks like this
default.aspx has userControl1
user can open up a modal from userControl1
modal has textboxes for updating
when user closed modal I want to then refresh userControl1 on the default.aspx page without reloading the entire default.aspx page.
First I am new to the asp.net world and am trying to figure out a weird issue that I am having. I have a page that has a form and on submit I launch another aspx file that exists in the same directory. The problem is the aspx file is shown and the file closes immediately! However, the weird part is if I make any modifications to the aspx file and save it and then run my application it works fine only the first time? Any subsequent submit actions launch the aspx page but then the aspx file immediately closes. But after I make some modifications to the aspx file..(simple ones) it launches correctly the first time. We are targeting .net version 4.0 and using IIS7. I am thinking that the asp worker process is doing something weird like checking for timestamps and closing it?!

View 2 RepliesI'm having some problems with connections to an SQL database not closing after being opened, which is maxxing out the pool and causing the site not to load any of the dynamic content (until eventually unused idle connections get close, as the problem seems to go away after a while).
I've been through my code several times and can't figure out where things are not being closed properly.
Is there a surefire way to make sure these connections are properly closed? Or to pinpoint where the problem lies?
Most places in the site I am using ObjectDataSource. You don't need to close a connection when using that, do you?
Where ObjectDataSource isn't used, a developer wrote this method and put it in a class file called "common.cs":

I searched the entire solution for every instance of "common.openDatabase()", and where it occurs I make sure there is a "cmd.Connection.Close();" that follows.
Am I missing something or doing it wrong?

I have been trying to close a dialog using code behind with no success.
The user should click a button, some processing is done and then the dialog should be closed.
I tried doing this using this code:
ScriptManager.RegisterStartupScript(this, typeof(string), "open", "window.top.close();", true);
But the dialog is never closed. What am I doing wrong?
I'm trying to close a web part in response to a particular click on part of my web part. Is there any way to close this within the code?
View 1 RepliesI should be closing my readers and connections in a more robust way? Some of my questions are:
- If a try-catch block is used, should the closures be done in the Finally section? Or in the main Try section?
- Should all closures assess whether or not the control is already open before closing (to prevent error)? (see closure of conn below)
- Are there any other preferable ways of handling this? Trying to improve my code!

I am working on a web application which is designed as master and web content pages. I designed login and logout for the application. When logout is clicked, it will call a method to clear the session variables and also some other methods which will clear some data in the oracle tables.
But if the user is clicking on the internet explorer close button, then there is no way to know that the application is closed. For this I got a link where we can write a javascript method and find the unload of the page and execute all of these but pages will be loading and unloading each time user navigates inside the application and I cannot depend on unloading the page.
how can I do all the process of clearing session and other things when user clicks close button of internet explorer.
Also this application needs to be holding the session for more than 1 or 2 hours, so session should not expire till logout is clicked or close button is pressed.
I have a web page (aaaaaa.aspx) which opens a popup window (bbbbbb.aspx). From the popup window vb.net code, I do a Response.Redirect("cccccc.aspx") to another page. On this page I have a button and when I click it, I want to close this page (cccccc.aspx) and refresh the original page (aaaaaa.aspx) so that the changes can be seen. Presently, the page cccccc.aspx close but the original page (aaaaaa.aspx) does not refresh. Normally this works fine with just a popup window. But the response.redirect is what messing me up, I think. I did not write this code but just trying to make it work. Here is the code I am using in the button_click event of page cccccc.aspx:
Response.Write("<script>window.opener.document.forms[0].submit();</script>")
Response.Write("<script>self.close();</script>")
I have created two user controls(Say uc1.ascx and uc2.ascx). I have wrapped second user control(uc2.ascx) as a DIV in first user control(uc1.ascx), to populate uc2.ascx as a JQUERY modal popup. I have created a Webpart(class file) where I specifed the first user control path. Now in an aspx page, I have added this webpart as a webpart zone. The syntax loks somethng like this.
<Webpart manager></Webpartmanager>
<WebpartZone>
<Zonetemplate>
<cc1:Customer...>
</ZonTemplate>
</WebpartZone>
In my first user control(uc1.ascx), I have gridview. Now when I clik on a button in a webpart, a JQuery modal popup comes where I fill the details and after saving the details, the popup closes. But the webpart is not refreshed due to which I am not able to get the updated data in the grid view.
How can I refresh a particular webpart when I have multiple webparts in the same page in order to get updated data?
I have a web app that opens various child windows from one main window. The main window itself changes based on user selections. How do I detect and close any child windows when the main window closes? I suspect I could use the session object to track the instances.

I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.
<%-- ************** CLIENT SECTION START HERE*******************--%>

I have an aspx page that has a button that, when clicked, will close the form. In the code-behind, I'm utilizing the Form_Closing() Event. Is it possible to use this event when a user clicks the X (can't remember what it's called) in the top right corner that closes a browser session? If not, is there a way of programming for this action?
View 11 RepliesI am using the xmltextwriter and having issues with opening tags not showing if the field is blank here is the start of my code
Code:

Dim objWriter As XmlTextWriter = New XmlTextWriter(strFilePath, New UTF8Encoding(False))
' start writing the XML document

conn.Open()
myreader = cmd.ExecuteReader
objWriter.WriteStartElement("testfile")
