I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.

I have a page that is using the Ajax asynch file uploader. What I would like to have happen is after the file is uploaded I would like to have it displayed in a list on the page. I am looking for a way to fire a callback event when the file upload is complete. Is it possible using the asynch fileupload control?

I am building a web site with visual web developer 2010
I have a class (autoButton) that adds a button to a panel (on Default.aspx) and a handler w/i the same class (classifyEventHandler)
The button appears fine, but when clicked the even doesnt fire, what am I doing wrong?
I tried locating the event handler in default.aspx, but it was not found :P
Imports Microsoft.VisualBasic
Public Class autoButton
Public Sub makeClassifyButton(ByVal theCell As Object)
Dim myButton As New Button
myButton.Text = "classify"
myButton.ID = "b_classify_" + theCell.ID
AddHandler myButton.Click, AddressOf classifyEventHandler
theCell.Controls.Add(myButton)
End Sub
Private Sub classifyEventHandler(ByVal sender As Object, ByVal e As EventArgs)
MsgBox("done?!")
End Sub
End Class

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?

I've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?"

I'm creating a GridView in code. I can successfully attach handlers for Editing, and CancelEditing. RowUpdating never runs, however. Instead, if the GridView is in a Panel, the Edit handler is called when Update is clicked (and this is the command name I get back on the Update click, too). If the GridView is not in a panel, then the Cancel handler is called when Update is clicked (again, this is the command name I get back from clicking Update). I've searched high and low for a reason why the RowUpdating event is not getting called, and I can't find one. Does anyone out there haveHere is my code (My actual code is much more involved than this, but for testing purposes, I extracted the following code and stuck it in a new project to isolate my problem):
protected void Page_Init(object sender, EventArgs e)
{
if (!IsPostBack)

I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?

In my web app, I used LinqDataSource, ListView and DataPager (.NET 3.5 sp1) to implement search feature with paging. I have a button to trigger the search.
But In the first time, the Selecting event of LinqDataSource fire twice and I don't know why (I debugged my code very carefully). I don't use QueryString with DataPager and assign PageSize of DataPager in the first time of page load to prevent the ListView bind again (as in some instructions I found in forum)
I can't post my code because it's quite large.

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)

My repeater:

A DetailsView in Insert mode has all fields cleared after events such as the following:
1. Clicking New.
2. Clicking Cancel.
3. Clicking Insert (if the default mode is Insert).
I have some fields linked to ViewState and they are populatd at PreRender event handler. I am wondring if there is a single place where all relevant ViewState elements can be cleared instead of doing this in all possible relevant handlers such as ItemCreated, ItemCanceled, ItemInserted, etc.

I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.
So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?
