I have a gridview control with some linkbuttons in.
When the linkbutton is pressed, i want the ID value attached to it, to be usually in the Page_Init where i need to create some dynamic controls, based on this ID.
But since the linkbutton's click event, is fired AFTER the Page_Init, this is a little hard for me to do.
How would i go about doing this, if it is even possible?
The reason behind, is that the linkbutton refers to a calendar event. Once clicked, it will list the details, but it will also list any comments, users have submitted about it. The dynamic controls i need to create, are delete buttons for the comments, so an admin can remove offensive comments.
All done on a single aspx page, with updatepanels (visible toggles, and populating labels). I would like to avoid sending users to another page, with a horrible ?id=6 link.
I am having a problem with web pages in a .Net site where the Page_Init is firing on each postback rather than the normal behavior (Page_Init fired initially, and only Page_Load fired on postbacks)
1. AutoEventWireup is set to false on all pages, with a "Handles Me.Init" set on Page_Init. All events are defined with the "Handles" verb as shown below
2. Each web page is subclassed to a parent class which provides strongly-typed access to the contents of session variables.
3. The Page_Load event for most of the pages performs a DataBind operation on a gridview control.
Partial Public Class SamplePage Inherits PageManager (PageManager inherits from System.Web.UI.Page) Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init ... End Sub
I have a gridview that includes dynamically created dropdownlist. When changing the dropdown values and doing a mass update on the grid (btnUpdate.click), I have to create the controls in the page init so they will be available to the viewstate. However, I have several other buttons that also cause a postback and I don't want to create the controls in the page init, but rather later in the button click events.
How can I tell which control fired the postback while in page_init? __EVENTTARGET = "" and request.params("btnUpdate") is nothing
I want something like this so that even if an individual user has two or more instances of that page open I am able to respond correctly to the immediate instance in Page_Init. Is it possible to achieve what I want or some facsimile of same? I know I can speculatively make an assumption and then check it in Page_Load when I have access to ViewState, but I would like something that approaches a best practice.
I need to create a user control which will be loaded according to the selected value of a dropdownlist. The Dropdownlist is not the part of Control. I want to pass the value of selected value of dropdonwlist to my user control and the user control will load according to the Value. For not postback it work fine. But when the page is postback, that is when i select a item form dorpdownlist, the user control is not loaded.
In one of my pages I use an usercontrol. The usercontrol has a textbox and a button on it. When someone adds text to the usercontrols textbox, I want to use the entered text in my page_init event. The problem is that in the page_init event, the textbox value is empty. How can I use the entered text in the page_init event?
I have an ASP.NET MVC web app setup and I need to know what the equivalent of page_init is for ASP.NET? I need to set the application to not cache anywhere. Is the global.asax the best place for this? If so, which event?
Basically, I need to put it so that everytime there is a postback, that event must be called. I am trying to turn off caching at all levels as this is a blackberry mobile app.
Is it possible to postback to the server, perform a function, and then continue that postback on to an external place? (ie, to a payment system)(the scenario is clicking a button to place an order, mark it as sent, then send them off to the payment page (there are form variables that needs to be sent to the payment screen as well))
I m trying to load a new tab which should load WebUserControl2.ascx on button_clickbut I m coming across this eror: A Zone can only be added to the Page in or before the Page_Init event.I have a webpart in WebUserControl2.ascx which should load FeaturedControl.ascx.Well, i m getting the error when i click on button at :
Private Sub LoadTab2() Dim uc2 As UserControl = CType(LoadControl("WebUserControl2.ascx"), UserControl) tp2.HeaderText = "Tab2" tc1.Tabs.Add(tp2) tp2.Controls.Add(uc2) End Sub
The value that is changed is accessed in the page_init event is being accessed but wrong value is being obtained because it is the page_init event, I am getting the correct value at page load however.I guess this is because the loadviewstateevent has notfired to get the actual control's values. Is there any way I can actually get the correct valueLike shall I save the value in a querystring and then when postback happens I can access that in the page_init event?I guess I am looking for a mechanism to set something in a website on the default.aspx page in a js function and I can access the changed control before the load and save view state.
I have some code I would like to execute very early in the lifecycle of a call to an ASMX function. For our ASPX pages, this code is in the Page_Init() function on a base class, from which all our ASPX pages inherit.
Is there an ASMX equivalent to the ASPX's Page_Init() function?
Better yet, is there an ASMX lifecycle diagram like the ASPX one? http://msdn.microsoft.com/en-us/library/ms178472.aspx
If there is an ASMX equivalent to Page_Init(), I assume I can implement code in a common base class, from which all my ASMX classes can inherit, correct?
My control needs to be populated in Page_Init...but the value in which I need to pass it comes from a combobox selectedindexchanged event...now I can set a session varable in the event handler and on next postback apply it to the control
So I have an asp:Login field on my login page. However, I want to use a path for the create account url and the forgot password url. So I have to do it in Page_Load or maybe Page_Init. Regardless, neither option works, it simply refuses to modify the login form.
I dont know if this is the correct section to post this question, but i'll take a chance.My question is:
Is it possible to do a URLRewrite in a Page_Init or Page_Load or a similar method instead of making a HttpModule? It is used in a online shop and all product url's should be like "www.blah.com/products/[categoryName]/[typeName]/[productName]. My problem is, that my client want to get rid of all .aspx extensions in the URL's but uses a webhotel where he doesn't have access to the iis. My solution is to use the Microsoft URL Rewrite module for iis 7 which is installed on the server and then catch the correct URL's. The problem is, that in the url's will be titles of the different things, and I need the ID's in the page i am going to rewrite to. So I must have somekind of a page in between which finds these id's and rewrites. But the page i have made in between won't rewrite the url - just stays on the same place.
I am currently working on an ASP.NET project, where I am using C# as my default language. I have an .aspx page, where I have an AJAX Script Manager and an AJAX timer. When that page first initializes, it does a pretty costly operation (parses a .csv file), which I only need to do once. However, every time the Timer tick takes place, Page_Init is fired again. Is there any way to correct it?
I have a code on the page_Init event where I parse a querystring and populate a page with images, in the querystring I have an date, and I use this date to dertermine if that url has expired. If the page has expired, I would like to redirect to another page saying that I can't process the request because it has expired. What do I put in the page_init that would halt the loading and processing of the page and redirect it to another page?
I'm creating a page that users can upload a file to the webserver. After upload the page will then have a link to the file that has just been uploaded, along with any other files that have already been uploaded.As I am programatcially creating links to the files which have been uploaded, I have to do this in page_init or else the link button won't fire off it's event when clicked. MY web page does all this - it creates the link buttons and when I click on them, it calls the event method required i.e. a sub to download the file.
OK, the problem I've come accross is: when I click upload (to upload the file) - the page_init sub is called, displaying all the previously uploaded files as link buttons. Then my btnUpload_click sub is called, which uploads my current file. The only prob is the current file hasn't been displayed? I can only display links in the page_init, but because btnUpload is called after the page_init, the current file isn't uploaded until after page_init and therefore not dislayed?
When we double click to page It creates an empty Page_Load event codeblock automatically. Or you know can create other control's event subroutine events by clicking the relevant event in properties window.
but how can we create a Page_Init ? is there an automatic way ? or should we just write its name and parametes manually is the only way ?
On my page: a Button1, a ListView1, a Panel1 and inside Panel1 an ImageButton1In the ListView1_PreRender-Event the property Panel1.Visible = false or Panel1.Visible = true is set.1. After first loading of the Page Panel.Visible = false ist set in ListView1_PreRender.2. After the postback click on Button1 the criteria for the visibility of Panel1 are evaluated, thus setting in the ListView_PreRender Panel.Visible = true.
I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
I have two server controls on page, both have buttons what must postback. One control uses validation and work ok. Other causes error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.
If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I`ve tried to set CausesValidation="False" Both controls are added dynamicaly so they do not know about other.
