I am developing a website and find problems on onunload event.
As the code below, it aims to modify the database when the 'X' of browser is clicked or it navigator to other page. However, when the AAA.aspx is loaded, it is found that end() would be run and already modify the database and change the status as 1, which is not my aim.
AAA.aspx:
<body onunload="<%end();%>">
AAA.aspx.cs: [code].....
BreakPoint not working in Init, InitComplate, PreLoad events in ASP.NET page with C# in VS2008. But it is working for Page_Load event.
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void InitializeComponent()
{
this.PreLoad += new System.EventHandler(this._Default_PreLoad);
this.InitComplete += new System.EventHandler(this._Default_InitComplete);
this.Init += new System.EventHandler(this._Default_Init);
this.PreRender += new System.EventHandler(this._Default_PreRender);
this.PreInit += new System.EventHandler(this._Default_PreInit);
this.SaveStateComplete += new System.EventHandler(this._Default_SaveStateComplete);
}
protected void _Default_InitComplete(object sender, EventArgs e)
{
........
}
protected void _Default_Init(object sender, EventArgs e)
{
.........
}
protected void _Default_PreLoad(object sender, EventArgs e)
{
..........
}
}
I have noticed that window.onunload event fires off AFTER page_load event which makes no sense.
This behaviour is creating an issue for me - in my unonload I clear the session, so if the Page_Load first BEFORE onunload, there are errors on the page displayed.
I would expect the javascript onunload to fire BEFORE Page_Load....is that the correct assumption?
TO CLARIFY: Let's assume I am on page test.aspx, then I click on the link that goes to the same page (say I click on a menu), what I observe is that Page_Load fires first, then onunload fires off.
Makes no sense at all.
as part of a log feature that my client asked for, I'm tring to monitor whenever the browser is closed by the user.
I have created a new web service, registered it the ScriptManager (like in this exmple [URL]
The web method is this:

When I put a break point it is reached, but the executenonquery won't fired.
I am working on a feature to throw a warning message if the user has unsaved values in a form. I can see that in the next post there is a explanation about how to do that [URL]now the problem is that i need to do the same but using a ascx control and i don't know where put the next code in my ascx control.
<body onunload="checkSave()">
NB: I'm working on dnn so that i don't have any change to add this code in the parent page of the control.
I am having an issue with a user control that contains a dropdown and a validator. I created a property for the "CausesValidation" property on the dropdown and set it to false. And yet the dropdown is still triggering the validator. I am having issues with this elsewhere as well including on my ModalPopup.
View 3 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesI have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
I have a fairly complex master/content page that has several GridViews - each one in its own UpdatePanel. I also have four CustomValidators on the page, each one assigned to a different
ValidationGroup. Two of the CustomValidators are buried inside a HeaderTemplates of a GridView (inside a distinct UpdatePanel). In the EmptyDataTemplate, HeaderTemplate and FooterTemplate of each GridView I have ImageButtons that postback to the server to perform some operation. All the ImageButtons take this form:
[Code]....
When I click on the ImageButtons in one of my GridView's the ImageButtons cause the ServerValidate event of two CustomValidators to fire. The server-side OnClick event of the ImageButton never fires. I have verified that the ImageButton(s) have CausesValidation="False" - what could be causing the validators to fire?
Here's a very strange thing happening and I need to know how to stop it. y ASP.NET web page uses a JSON Ajax call to call a Webmethod that initiates a number of processes. In the IDE when I step my code. Because I'm only testing the first part of the process, there should be no action against the Database until the 2nd phase. I place a breakpoint at the start of the 2nd phase and then I actually stop debugging by pressing the usual square button. I then look in a table on the DB and records have been processed that should not get processed until much further into my code. Stepping line by line until my breakpoint does not call any update functions to the Database (just in-case I'd placed a call somewhere that I didn't mean to). Can someone tell me what's going on in the IDE? At my breakpoint, depending on how long I leave it sitting at the breakpoint before I actually stop the debugging process has a direct impact on the amount of records I see changed/added in the database.
View 9 RepliesI have an inline .asmx file that I'm trying to host on GoDaddy. Because of this, I cannot edit the web.config file :(. Either way, I can access [URL] When I try this, I see the service description page that ASP.NET generates. However, when I try to access the method, I receive the "Request format is unrecognized for URL unexpectedly ending" error.
I have not changed the .asmx from what Visual Studio generates. I'm simply trying to access [URL] as described here: [URL]
My question is, is there a way that I can host .asmx files on GoDaddy? From my Googling (or Binging) it seems that I need to edit the web.config file to be able to run this service.
Here is my code:

I have a products page, with a treeview on left, (telerik) and on the right there is a div. The div on the right is used to load stuff in it, (using jquery, calling another aspx with a querystring parameter), called from Telerik Treeview's client-side OnNodeSelecting event ... Everything works as expected. There is also a RadioButton list (asp.net rbl) on top of this page, that is set to AutoPostBack. It switched the current language of the page. In all the other pages, it changes the Language and reloads the page. Then browsing the proıducts is pure client-side by loading into the rihgtmost div, (jquery calling another aspx page with a parameter, and loads the resulting HTML into the div).
What happens is, once I load content into this div, and then try to select another language from the RadioButtonList, whole window redirects to the aspx page that is supposed to provide the content to jQuery load. I have absolutely no clue why that happens.
Code below:
TreeView is actually inside an ascx. The client-side code is
$(document).ready(function() {
loadproduct(getDefaultUrl());
});
function getDefaultUrl() {
var hf = document.getElementById('ctl00_cphContent_hfLastSelectedProductUrl'); ///this is for preserving the state
var url = hf.value;
return url;
}
function UrunMenuNodeClicking(sender, args) {..........
note: the Class MyControl inherits from System.Web.UI.UserControl , and has a property that accesses Session and sets the current language as an integer. Actually it is an enum like Languages.English, I do (int)enum and send it to session ...
I'm using the code below in the we.config file.
<sessionState mode="InProc" cookieless="false" timeout="30"/>
There is no issue with the session expiration locally, but the same web application logouts frequently when I uploaded it to the webserver. The session no longer keep it's state for 30 minutes when the application left idle for some time.

So I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.

I have a couple of validators on a modal popup. They trigger properly for the controls on the modal. On the main page I have an updatepanel and can commit a save. When I commit a save and go back to the modal popup the validator error messages for both validators appear. Why is this happening and how can I stop it?

I have a web service hosted on a web server, I invoke the web service using jquery ajax.
The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain).
I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

I can open the modalpopup, can close the popup, but if i click the "edit" button to edit any of rows, the popup closes automatically. If I click again, the "Update" and "Cancel" buttons shows, and after clicking one of those, popup closes again. The above code works, if i use gridview the insert, edit or delete the data, does not close automatically. What may be the cause of this problem.
I have the project in vs2008. I find that there is difference behavior between VS2008 Debug Mode IIS and Windows 7 IIS.
I have published the project and deploy on windows 7 IIS.
Different examples: After login, VS2008 debug mode can go to default page but not in windows 7 IIS in which it return back to login page after login. Sometimes, they can login but still difference behavior in page reload such as dropdownlist databind.
I have been trying to use some of the controls in vs2008 and I am having probems. 1) When I try to choose multiple controls the control nor shif key works and I can only click on one control at a time.
2) When using wizard, panel, ajax tab control, etc. I cannot get my other controls to go inside the boxes. They want to land elsewhere on the page (Outside the box). I have tried copying, moving, a new pull, etc. Can anyone tell me what I am doing wrong or direct me to a tutual on this.
3) In Ajax tabs the tabs are so small that I cannot read the text in the tab. I have tried to enlarge etc. but it's not working. Also, when I try to pick on a tab to change tabs, my tab doesn't change and I cannot get the controls to go into the right tab.
I have an ASP.Net application that I am developing on my localhost. I have v.2.0.50727 installed and running. I have registered and re-registered this version ASP.Net several times. So far I am having no luck and continually get a "Server Application Unavailable" message. The funny thing is, this only happens on .aspx pages. Additionally I have ensured that the application is set to run ASP.Net 3.5 in VS 2008.
I have no further information to provide as none is being provided to me by the application. To add a wrinkle... on a seperate local machine, everything is working properly. I am fresh out of ideas as to why this isn't working. I have tried pretty much everything else I have researched with no luck. The only error I am seeing in the log is:aspnet_wp.exe (PID: XXXX) stopped unexpectedly.
