I am using jQuery confirmation box within my listView and the confirmation box displayed with the user clicks delete. The problem that I am faced with, is that when the user clicks OK it, the lvAlbums_ItemDeleting event is not fired.
Below is the .aspx code:
<link href="jQuery/jquery-ui.css" rel="stylesheet" type="text/css" />
<link href="jQuery/jquery-ui-1.7.2.custom.css" rel="stylesheet" type="text/css" />
<script src="https://www.google.com/jsapi?key=" type="text/javascript"></script>

I have spent days looking at different jQuery confirmation box examples but this is the best I can do. Ideally I would want to be use [URL] within gridviews, dataViews and ListViews but can't find examples which exactly provide steps to follow.

I have an asp.net app that launches a modal window upon button_click event. That modal window launches another modal window upon another button_click event.
However, the final modal window's "Page_Load" event is not firing.

Here's the situation: I have a variable number of dynamically created update panels on my page, so I thought I would write one method which handles all of the loading for each one.

I have a asp grid with a few columns that bind to data. The last column has been converted to a template-field. In this template-field is a button with a modal popup extender attached to it. Hidden inside this field is a modal popup. This modal popup is used to add a new account. it contains 2 text boxes, drop down lists and buttons("Add" and "Cancel"). When "add" is clicked the modal should close after the inserting of the new account in the code behind.
The Problem: I get the popup to display and load the Drop down lists from the cache, without problem. How do I get the button click event to fire in the code behind. I've tried using a JavaScript function that performs a _doPostBack('btnAddAcc','') but it keeps returning the error "JavaScript error: Object expected". I gathered after about 1 hour on Google that it is because "btnAddAcc' is not found because it is actually within the grid-view cell and can't be directly accessed. Using page methods and ajax calls is a last resort as the company has a strict policy against this and only allowes this after a bunch of paperwork.
The Code:
<asp:GridView ID="gvNEA" runat="server" CssClass="gridA_Orange"
AutoGenerateColumns="False" AllowPaging="True"
EmptyDataText="No transactions with 'Non Existent Account(s)'"

I have a DataGridViewComboBox in a dgv and I need to detect when the user changes the value....I thought I could use the CellContentClick; however, it doesn't fire when I select from the dropdown in my dgv so thinking I need a different method to choose from.
View 8 RepliesIn my view there is this DropDownList:
@Html.DropDownList("fOrderstatus", TryCast( ViewBag.StatusOptions, SelectList), "--pick--", New With { .title="Pick an orderstatus"} )
The view shows purchaseorders and the dropdownlist should give the user the possibility to filter, e.g. choosing only 'active' orders.
I prefer a solution in plain vanilla ASP.NET MVC.

I can't quite get a variable to pass between buttons. The variable that I want to pass is totalNumbers and each time a different button is pressed its supposed to subtract a predefined number.

What I am trying to do is put a sub procedure inside a button that will be passed back and forth between my call statement and my private sub btnBegin.

How to this through an on change event

I'm creating a number of textboxes, all calling a function during the onchange event to update their value to the database. These boxes are dynamically created in the backend because the data changes based on specific criteria that can be changed on the page. Here's the creation of the boxes:
Dim t as TableRow
tC = New TableCell
Dim txtBox As New TextBox
[Code]....
When I enter a number into the Textbox, the event fires as expected, but it fires twice.
see i have a form in that i have following controls
.combobox
.textbox
.listview
the combobox contains all the column names of listview like docid,firstname,surname etc
when the form is loaded the listview is populated with some data from the database.
is there is anyway to autopopulate the listview control based on search term entered on the textbox.i heard about the "onchange event",but i'm not sure how it works .

I am using a monthcalendar inside of a panel. when the user changes the "showweeknumbers" of the calendar I need to move some label to the right of the calendar, but I also need to resize the panel. The problem comes into play when the user hides the weeknumbers, the monthcalendar resize event fires and the labels move, but the panel resize causes the month calendar to fire the resize event again, making the labels all out of wack...

I have the following code:
Private Sub Exceptionquery()
Dim connection As System.Data.SqlClient.SqlConnection
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
[code]....
I get the error Invalid Object name 'Scratchpad3' on this line:
adapter.Fill(ds)
I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:
Exceptionquery()
I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.

I've been looking for a solution to this for several hours now and cannot find a solution.
The Scenario:I have a masterpage baseclass (called basemaster)All of my master pages inherit from basemaster
basemaster defines an event 'Public Event HandleClickEvent As EventHandler'I have a masterpage named master1
master1 defines an event handler 'Public Shadows Event HandleClickEvent As EventHandler'master1 has a user control named usr1 usr1 has a button that raises event ButtonClicked when clicked I have a page (thePage) that uses master1 thePage has a button click event handler that it registers like so: 'AddHandler Master.HandleClickEvent, AddressOf HandleTheClick' master1 has code something like:
Protected Sub Usr1_ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Usr1.ButtonClicked RaiseEvent HandleClickEvent(sender, e) End Sub when thePage loads I see it register the handler on master1 when the button is clicked, Usr1_ButtonClicked is fired and I step through the RaiseEvent but HandleClickEvent on thePage is never reached.
I am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.

The problem im having is a little complicated to explain, so please bear with me. I have 2 button controls. In the page load, I wanted to know what button created a postback on the page load. Through research I have found this snippet below and it works as expected. So here is my scenario of events that occur when click on the button.
1. Click the button does a postback
2. Runs the function below and tell me the id of the button
3. Runs the clicked event handlers for that button [code]
The problem comes in when I click the second button, it does steps 1 and 2 but NEVER DOES 3. Through testing, I have that it only does 1, 2, and 3 on the first button clicked.[code]
