Configuration :: No Event Fires Except Page_load In Aspx Page?
Aug 12, 2010
I have a page which contains linkbuttons and panels. all panels have DetalilView and gridView controls. On click of linkbutton, panel's visibility is set. everything works fine on my local server. But on production server, no events of Button, DetailsView and GridView fires.
Page_load event fires two time in firefox and the same page is working fine in IE. What might be the problem? If it is problem with Autoeventwireup then page_load event must fire two times in IE too. I believe it is not a issue of Autoeventwireup.
I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?
Basic concept of AJAX is to cause Partial post back of the Page. If we use AJAX, Page Load occurs, than what is the difference between normal Pages' Page_Load event (without ajax) and Page load event of a Page with ajax.
I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then RaiseEvent FirstLoad(sender, e) End If End Sub
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad 'Stuff here happens before controls load but only on first page loads' End Sub
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.
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.
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
I have a web page with a nested grid. I bind the nested grid via the outer Gridviews RowDatabound. The problem I'm having is when a user click on a CommandField in the nested child grid the Page_Load event is fireing twice and reloading the grids, making it appear that the nest grid collapsed. I have tried using "If Not Page.IsPostBack" but because the page posts back twice the IsPostBack is false until the second time the Page_Load event fires.
Here is my Page_Load routine
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim test As Boolean = ScriptManager.GetCurrent(Me.Page).IsInAsyncPostBack If Not Me.Page.IsPostBack Then If Not ScriptManager.GetCurrent(Me.Page).IsInAsyncPostBack Then
I have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
I have an aspx page that is wrapped with an UpdatePanel control, users can post comments and delete them later, when the user clicks the delete for the first time it deletes successfully but if he wants to delete another comment, it works only after two clicks on the button.the delete button is inside a web user control that is added dynamically at run time.
I was under the impression that static files (CSS, images, @font-face files, etc) bypassed ASP.NET completely, and were served directly by IIS. However, my BeginRequest event handler is being called for every HTTP request, including those for static files. This concerns me because I'm creating an Entity Framework data context to be used for the lifetime of each request in that event handler. I don't want to create those contexts if they're never going to be used.
I'm using IIS 7 on Windows 7 Ultimate with so special handler mappings defined. Do I have it wrong? Should these events be firing?
