The iPhone sends an HTTP GET request to my web application to recieve an update for an internet calendar. The iPhone does not conform to the RFC 822 Date Format for this request. It sends the If-Modified-Since as follows:
RFC 822 format - Sun, 06 Nov 1994 08:49:37 GMT
iPhone Format - Sun, 6 Nov 1994 08:49:37 GMT
I dont know much about handlers or modules. Is it possible to write a handler or module that could intercept this request and reformat the If-Modified-Since date format to the standard. Currently when IIS recieves this request it immediately sends back a 400 Error because of this invalid format.

Currently I am implementing code from this example. In my aspx file, I have Label1 and Textbox1 defined. In my aspx.cs file, I am setting the Label1.Text property to a random string in the Page_Load method.
In the .js file I have included, I have:
var Label1, TextBox1;
Sys.Application.add_init(AppInit);
function AppInit(sender) {
Label1 = $get('Label1');
TextBox1 = $get('TextBox1');
[Code]....

I am wondering how to add a javascript event handler using asp.net ajax. I need to add event handlers after ajax update because Jquery plugin to sort tables doesn't work and the onload method to display a screen keyboard does not trigger as well. Is there a way to do that? Maybe I need to switch to some other ajax library or/and try Asp.Net MVC to accomplish?

Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?

Using vb.net/asp.net 2005.
I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.

I have a Silverlight control on page which has a upload control. the silverlight exposes some events such as
StartUpload() => To start the file upload,
StopUpload() => To stop the file upload if running,
CheckFileStatus() => to check the status of the file upload.
The page has aspx Submit button with onclientclick event and ocClick event.
<asp:Button ID="btn_upload" Text="External Upload" runat="server" OnClientClick="Javascript:StartUpload();"
OnClick="btn_upload_Click" />
When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called.

I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...

I checked my html page generated by asp.net and I can see this line
Sys.Application.initialize();
Sys.Application.add_init(function() {
$create(AjaxControlToolkit.CollapsiblePanelBehavior,
{
"ClientStateFieldID":"rptActiveQuotes_ctl01_qcQuote_cpeDetails_ClientState",.......
I think it's generated from CollapsiblePanelExtender with name cpeDetails. And I see you can pass number of events to it, wich is now null (third argument). What should I do to set add_ended event there?

Simple question here, but I've got a nagging feeling that there's a more interesting solution than the one I've chosen:
Page Two consists of a dropdown, and the change event is handled to execute some query.
protected void ddlSavedQueries_SelectedIndexChanged(object sender, EventArgs e)
{
/* stuff happens */
}
Page One is a home page, where I'm providing another version of that dropdown. I'd like the change event in this case to redirect control to Page Two, and then execute the event handler.
My cheap solution is just a Redirect with a querystring value that is handled on page load.

I have a master page that contains a navigational menu, made up of nested databound repeaters. Buttons are created for the outer-most repeater's items. When the user clicks on one of these buttons, the content page loads and a label within this content page changes to reflect the text from the button that was clicked. In other words - click a button, load the page, change the label on the page to the text on the button. I have tried also changing the initialization on the content page from Page_Load to Page_PreInit to Page_Init, and nothing seems to matter as I'd like to move on in this project! Code follows:
Master Page (Site.Master):
[Code]....
Content Page (BatchView.aspx):
[Code]....
The problem is, whenever a button is clicked, it changes the title of the master page to 'Not Working', which lets me know that the TeamChosen eventhandler is null!

I will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?

The trouble is while the event handler for the btnSearch fires, the same can not be said for the btnSave handler.
Anyone see what obvious thing I have missed.

I have a button on a masterpage, which when clicked, calls a method that takes an EventHandler previously saved to the viewstate, this method is on the client page, and executes it:
protected void Save_Click(object sender, EventArgs e)
{
this.SaveButtonEvent += (EventHandler)ViewState["saveEvent"];
if (this.SaveButtonEvent != null)
{
this.SaveButtonEvent(sender, e);
}
}
This then calls a very simple method on the client page:
protected void Button2_Click(object sender, EventArgs e)
{
Label1.Text = TextBox2.Text;
}
However, the value of TextBox2 is incorrect, it is the value of the text box that was set when the page loaded (or if any other item on the pages changes it), the new value is not passed.
If I add a button to the client page, that calls the Button2_Click event directly, it get's the correct value.
Is the reason I am not getting the correct value of the text box because the Event is called from the master page?
I should add, that this button is created dynamically, and the event delegate will vary, which is why I have to set it at run time. I need a way to set the delegate on a click, and persist this until it is changed again.

I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).
My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist? Markup of Repeater on page:
<asp:Repeater ID="rptrActivites" runat="server" EnableViewState="true">
<ItemTemplate>
<div class="activity">[code]...
Page's code behind:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
GetActivities() [code]....

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've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.

This event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.
