View 2 RepliesI thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen: Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information: Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.
I've read that OnClick is executed on the server and onClientClick is executed on the client. Is it better to use OnClientClick to do something like close a modal popup?
If my understanding is correct then this would avoid a trip to the server to accomplish the same task. This would be great for something that doesn't need to make a round trip to the server and back.
I've created 2 controls to manipulate a data object: 1 for viewing and another for editing.
On one page I load the "view" UserControl and pass data to it this way:
ViewControl control = (ViewControl)LoadControl("ViewControl.ascx");
control.dataToView = dataObject;
this.container.Controls.Add(control);
That's all fine and inside the control I can grab that data and display it.
Now I'm trying to follow a similar approach for editing. I have a different User Control for this (with some textboxes for editing) to which I pass the original data the same way I did for the view:
EditControl control = (EditControl)LoadControl("EditControl.ascx");
control.dataToEdit = dataObject;
this.container.Controls.Add(control);
Which also works fine.
The problem now is getting to this data. When the user clicks a button I need to fetch the data that was edited and do stuff with it. What's happening is that because the controls are being added programmatically, the data that the user changed doesn't seem to be accessible anywhere.
I have problem with user control: MyCollection : UserControl
MyCollection contains:
[code]....
Works fine unless I register event for some button:
button1.Click += ...
When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.
Button in this collection MyCollection has odd ClientID - itemsAddresses$button1
I'm having some problems with the module urlrewriter.net for ASP.NET.I have a multilingual site with a URL like this;
~/home.aspx
To support languages I use this rewrite rule;
<rewrite url="~/de-DE/(.*)" to="~/$1"></rewrite>
Then in my code I get the de-DE part and set the right culture for the current thread. All of this works well.After I login on the website I get a message "Hello, user x" to show i'm logged in. When navigating to another page, it doesn't display this message anymore and it seems like the page comes from the cache or something with the old (not logged in) data. Also, when I attach the debugger, nothing is executed for this request. If I visit the page like ~/home.aspx instead of ~/de-DE/home.aspx, does problem does not occur.
I have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.
View 2 RepliesWhen user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution 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 have required field validators in my ASP.NET application form.
In the button click event of the FORM, i.e. OnClientClick(), I am calling a javascript function to validate the controls in this same page. Due to this the required field validators are not getting fired.
I need both the javascript function be fired on the button click , as well as required field validators also to work efficiently.
I have a webform where I have validators and submit buttons.WhatI am looking for one of my button is1. When its clicked, if all the validators are satisfied, 2. If all the validators are ok, It should disable the button for postback so that user cannot click it again during its process ( means during postback )3. it should enable back after postback if possible otherwise I can do it from code behind at the end of my process,
View 3 RepliesI have created a form with several textboxes and a dropdown list and assigned a required field validator to each of them. I also have a master page with several links to other pages, some made using <a href=..> and some linkbuttons. The problem I am having is that when I click the linkbutton links they do not redirect to the proper page, rather they trigger the validators for all textbox fields and display the validator characters next to each textbox (and the dropdown). When I fill out the form, those links redirect properly. The links created using <a href=..> do not cause this problem.

I think normally the execution sequence is content page's controller first, then master page (I have some inline code).
But now I have a situation that master page's inline code is executed before content page's controller.
I'm loading a web page into an iframe. As the web I'm trying to load have some heavy stuff it takes a while to load. As it's not my page I cannot change the HTML code neither the codebehind, so I want to put a progress bar while loading the web into the iframe and stop when it finishes loading. I'm doing it through javascript and I tried to trigger it in every load/unload event of the webs codebehind with bad results. Finally, I tried to trigger it in the body's onload event. It seemed to work, but the progress bar dissapears a couple seconds before the web is fully loaded into the iframe.
Its possible to know when the web has finished loading the iframe or when the web page which is loading in the iframe has finnished loading?
I have a user control with contact form and validators, when I add it (user control) to my parent page I get a strange behavior of all buttons within the parent page, Any button I press on the parent page fires the validators of the user control. How can I vallidate the form on my user control only when I press a specific button?
View 3 RepliesMy aspx page is not showing latest data after reopen the page.. but after save data it shows latest information.
If I close the project and rerun the project then it shows latest data.
Interesting metter is the page_load event is not fired after thie page loaded once.
If I delete temporary internet files from tools-->internet option then the page reloaded.
I have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.
I have web page that will call the macromedia detection tool kit. But I cannot get the hasReqestedVersion value before the page is loaded. I tried to use RegisterClientScriptBlock or RegisterStartupScript inside of the Page_load function.

I am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?
I have a hyperlink on my master page that directs me to the homepage. It works on every page except a page that has validators.How do I make the hyperlink work?
View 1 RepliesI want to initialize text box with specific dates and after page is loaded, user can change dates and refresh the data on page.
When I set default date on pageload event, user's changes get lost as soon as page is refreshed.
txtStartDate.Text = DateTime.Now.AddMonths(-2).ToString();
txtEndDate.Text = DateTime.Now.ToString();
In past, I have used onInit event for such initialization but I am unable to find it on web form.
