This gets called when I go into Insert mode just fine, but it also gets called when I click the INSERT button to insert my record. I am trying to use this function to set default values for those controls on the form.

Events Not Firing For DataList And GridVeiw

Feb 3, 2010

through the Sitepoint book "Build Your Own ASP.NET 3.5 Web Site". In chapters 10 and 11 the book covers the DataList and GridView.My project will load data correctly into the list and grid; however, the events are not firing, for example the SelectedIndexChanged event. As far as I can tell no list/grid events are being fired in the code-behind file (the page load event and data binding does occur).There are some similar posts in these forums and on the internet concerning this.

C# - Nested GridView Not Firing Row Events?

Aug 4, 2010

I have a nested GridView that is placed inside a ListView. The GridView renders perfectly fine with all the entities that are bound inside its datasource.

Each record in my gridview has two buttons - 'delete' and 'edit'. The issue that I am having is that the methods wired to each of these buttons never get fired.

I think the reason for this behaviour is because my ListView's data binding happens only on the first page load, and not on every subsequent postback. As a result, when a postback happens, the events of the nested gridview are never wired up again - hence my methods are not getting fired.

Here is what my code [simplified] looks like:

[code]...

I tried modifying the above code and removing the "!IsPostBack" clause, and the events actually got fired when a button inside the GridView was clicked. However, I do not feel comfortable doing a databind on every postback and think there should be a better solution than that.

C# - Default.aspx Not Firing Events?

Aug 27, 2010

We have recently put up a new server with IIS7, where we now have published a .NET4 site.

Locally everything works fine, but on this server the Default.aspx is not working. No events are firing at all for this page. Every other page works as should.

We've tried deleting the Default.aspx and adding a new blank one with just a button event but same thing still applies.

We've spent quite some time troubleshooting this without any results. Same problem exists both with and without using a masterpage.

VS 2010 Button On WebUserControl Click Events Not Firing?

Dec 24, 2010

I have a WebUserControl with a Button and some other controls (placeholder for images, labels). On a certain page, a number of these WebUserControls are created (using Me.LoadControl) and added to a PlaceHolder on the page.When the user clicks the button on either of these usercontrols, I want a method on the page to be called. I have been doing this by handling the Button Click event on the usercontrol, and then letting the usercontrol raise another event. I use AddHandler after creating the usercontrol to add an eventhandler method to this custom event. Sounds confusing? Here's a simple example.

The WebUserControl:
asp Code:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="TestControl.ascx.vb" Inherits="CSLimitedEdition.Controls.TestControl" %><asp:Button runat="server" ID="btn" Text="Button" />
vb.net Code:
Namespace Controls Public Class TestControl Inherits System.Web.UI.UserControl Public Event ButtonClicked As EventHandler ' Just some property to test with Public Property Number As Integer Protected Sub btn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn.Click ' When the button is clicked, raise a ButtonClicked event to handle on the Page RaiseEvent ButtonClicked(Me, e) End Sub End ClassEnd Namespace
The Page to place a number of these controls on:
asp Code:
<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="TestPage.aspx.vb" Inherits="CSLimitedEdition.Pages.TestPage" %><asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"></asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <p> <asp:Label runat="server" ID="lbl" /> </p> <p> <asp:PlaceHolder runat="server" ID="placeHolder" /> </p> </asp:Content>
vb.net Code:
Imports CSLimitedEdition.Controls Namespace Pages Public Class TestPage Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Me.IsPostBack Then Me.AddControls() End If End Sub Private Sub AddControls() For i As Integer = 1 To 5 ' Create the control Dim c As TestControl = DirectCast(Me.LoadControl("~/Controls/TestControl.ascx"), TestControl) ' Set some property for testing and add event handler c.Number = i AddHandler c.ButtonClicked, AddressOf TestControl_ButtonClicked ' Add it to the place holder placeHolder.Controls.Add(c) Next End Sub Private Sub TestControl_ButtonClicked(ByVal sender As Object, ByVal e As EventArgs) ' When a button on a usercontrol is clicked, set the label text to the 'Number' property of that control Dim c As TestControl = DirectCast(sender, TestControl) lbl.Text = c.Number.ToString() End Sub End ClassEnd Namespace

The idea is this:Button is clicked on the TestControl: TestControl.ButtonClicked event is raised. On the TestPage, the bestControl_ButtonClicked method is called The Number property of the calling TestControl is assigned to a label so I can see it. However, it seems that the TestControl_ButtonClicked method is never called. Via debugging I can confirm that the Button Click event, on the TestControl usercontrol, is fired, so that the TestControl.btn_Click method is called. The TestControl.ButtonClicked event is raised.After creating a TestControl, the AddHandler statement is executed. After clicking a button on the page however, nothing happens. The page just posts back, all the buttons are gone (ok, I'm not loading them again in case of a postback), but the label does not get the text.In fact, the ButtonClick handler method (TestPage.TestControl_ButtonClicked) method is never called! What could be causing this? I am sure that I have been using this method a few weeks ago, in this very project, yet suddenly it has stopped working. I thought it might be a one-time thing but with these new TestControl and TestPage the same thing happens. The same thing happens also in a completely new and separate project. I don't get it, this WAS working?

Web Forms :: Stop Search Engines Firing Events?

Jan 7, 2011

How can I stop Search engines firing events.....

I have a button that adds a product to my shopping basket. it has a postbackurl="../shoppingbasket.aspx?productID=1" when the page is loaded I get the querystring (ProductID) and add it to my database. Well I have been watching the database and I can see that in 1 day the whole of my product range has been added to the shopping basket, not only that but every time it fires the event it creates a NEW basket thus messing up my shopping basket ID's.

So my question is, I want the search engines to index my product pages, BUT I do not want then to add to my basket ( i.e. firing the postbackurl ) I have tried may things like rel="nofollow" adding the URL to my robot.txt. I don't really want to use recaptha as I have do before and have many complaits about it.

Events - Button_click Not Firing, After Browser Back Button?

Jun 18, 2010

I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction.

On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again.

Web Forms :: Dynamically Created Checkboxes Not Firing Events Correctly

Apr 27, 2010

I've dynamically created 3 checkboxes as you can see in the code below. I also wrote an event handler below. When I run the code, the 3 checkboxes show up, but the event handling does not work right. Whenever there is postback from any of the 3 checkboxes, Label1 reflects the state of checkbox #3, no matter if I toggle checkbox #1 or #2. I put the code I have under Page_Init into Page_Load instead, but makes no difference either way.

The bottom line is, I want the event handler to know exactly which of the 3 checkboxes is firing the event so that Label1 can reflect that.

GridView OnRowEditing Events Not Firing When Using Unity 2.0 HTTP Module?

Jan 31, 2011

I have an ASP.NET web forms site using Master Pages. It is using Unity as my IoC container. I have created an HTTP Module to build up the container using a couple of tutorials i found online. I need the dependency injection to work for User Controls and the only way i was able to get this to work was to hook into the Pages PreInit event as can be seen from the code below.

[code]....

I also have autoeventwireup set to true on the pages and master page. Can anyone shed any light on why the events are not firing? Is my Unity http module causing this to happen by dropping the event wiring? I can get this to work no problem in a basic example with no IoC involved.
