Javascript - UI Confirmation Not Firing The Event?
Feb 13, 2011
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>
[Code].....
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 would like this ASP button control to stop calling its event handler when the JavaScript client method IsCorrectPrice() returns false.
<asp:Button ID="btnsubmit" runat="server"
Text="Submit" OnClientClick="javascript:IsCorrectPrice()"/>
btnsubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Handles btnsubmit.Click

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 want to have a confirmation message box pop up when a user clicks the cancel button on a form. I believe this would be the correct javascript code:
function confirmation() {
var answer = confirm("Are you sure you want to cancel? Any information you have entered will be discarded.")
[CODE]...
But, I'm not sure how I can call the function with VB from my code behind page.

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.
The second modal winodw is called via a javascript call from vb.net code behind Page.ClientScript.RegisterStartupScript(Me.GetType(), "Script", "ShowModalWin('brPreview','brPreview')", True)

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.
My Updatepanel creation looks something like this:
Dim newUpdp As New UpdatePanel
newUpdatep.ChildrenAsTriggers = False

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'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've bound a bindingsource to a datagridview and each time i move the cursor on the datagridview to a different row, the positionChanged does not fire. This event handles other bindingsource too and I hv no problems with other datagridviews.
Im couldnt work out the behaviour for this particular datagridview.

I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.

e.Row.Cells("ID").Value = Me.cbxID.Text
e.Row.Cells("Rate").Value = 12

I've got the above event setup. However after select and delete the last row of a one row datagridview, the above event doesn't fire. Even when the current selected row is the new row (one with *). I have to click away, on the next tab and back again before it is fired and populated the new row with the values.

I used a timer in my user control now when Timer_Tick event is fired I want to raise an event like Ticked. I created:
public delegate sub myDel()
public event myevnt as myDel

I have a tabbed container, each tab has the same controls but for a different target. I am using a timer to control when to fire each event from the 5 different tabbed controls, my problem is this. The event only fires when the focus is on that specific tab. So when an event on tab2 should fire, if i am looking at tab1 then tab2 event does not fire.
