Web Forms :: Drop Down List SelectedIndexChanged Not Firing

May 29, 2010

I am developing a C# / SQL website application in VS 2008 and using SQL Server 2008. I am a newbie. Right now though I can not get the drop-down box to display the SQL table columns. This application should return all of the rows from the selected table. And then I append one row = IGNORE to the end of the list. But when I run this app the first time, it correctly displays the list of available values from the table and appends IGNORE on the end. However, after postback it only displays IGNORE value for me to select. I thought this might be a Viewstate or Autopostback problem, but I tried changing these values and it did not fix it. Here are excerpts from my code.

The problem is that the "targettable" variable is null after postback. But I don't see what is causing this.

Button Click Doesn't Call Function Even When Button Attribute OnClick Is Set To That Function

Mar 19, 2010

I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?

Populate Drop Down List On Click In Repeater?

Jan 31, 2011

Is it possible to populate the values of a drop down list inside a repeater when the user chooses to activate the drop down list? I have a page that has 2300 rows of data generated by a repeater. The users have the option of showing a drop down list or not. If the drop down list is shown, right now I bind the values in the drop down list at the time the repeater is generated so they are available immediately.However, this adds an additional 2mb of data to the page, which increases the amount if time that it takes to render the page. I am being asked to decrease the page size. The idea they have is that if I only load the first value of the drop down list into the repeater, the amount of data on the page would drop significantly (which it does).

The problem becomes, how do I then load the remaining items into the drop down list when the user SELECTS the drop down list? These aren't static values, they are completely dependent on the data row key, so I have to go out to the DB and get the values for that individual row.I thought maybe AJAX and jquery, but can that be done inside the repeater?Ayone have any ideas as to if/how this could be done? Personally, I think the users should be educated that it is going to take an additional 5 seconds for the page to load if they choose to display the dropdowns, but the business is hesitant to go that route.

Jquery Button Click Not Firing Button?

Jun 1, 2010

I've got a .net button that has an href attribute value set to

javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$cp1$ucInvoiceSearch$btnSearch", "", true, "", "", false, true))

I've got a textbox that when I press enter I want it to fire this event. Doing the 'Enter' event isn't an issue but I can't get the event on the href to fire using .click(). Here's my function so far:

C# - OnClientClick And Click Event Together For A Button Is Not Firing?

Feb 21, 2011

I have Onclientclick event attached to the button in serverside code like below,TopPanelButton.OnClientClick = string.Format("if(!ValidData({0},{1},{2},{3})) return false;", txtOD.ClientID, radCmbOD.ClientID, txtgetMe.ClientID, RadAjaxLoadingPanel1.ClientID);Also, the onClick event is attached for the same button in the aspx page,

<asp:Button ID="TopPanelButton" runat="server" Text="Go"
CssClass="CBtn1" Width="30px" Height="21px" OnClick="TopPanelButton_Click" />

The serverside click event should fire if the onclientclick return true. The "ValidateData()" function is called to validate the entries in the form.This code is working fine in IE. But in Firefox, both events are not firig. If I comment the "TopPanelButton.OnClientClick =..." code then onClick event is firing.

Vb.net - .net Webpage DefaultDocument Button Click Not Firing?

Oct 20, 2010

I have developed an asp.net website in VS2010. The defaultDocument is set to default.aspx in the root directory, as I have dome many times before.For reasons unknown an asp:button in default.aspx is not firing correctly when the url is typed in without the file extension.

For example, if I type the url www.mywebsite.com the default.aspx page will load as expected, however, the button will not fire (it does postback but doesn't fire the server click event).If i type in the url www.mywebsite.com/default.aspx it works as expected.

The problem I'm having only occurs in a live environment (I cannot recreate the error on the localhost).

Web Forms :: Firing A Button Click After Page_Load?

Mar 24, 2011

I am designing a page wherein I want to display just parts of a page on page_load (i.e. menu bar). Then a few seconds later, I would like to display the rest of the controls (i.e. charts). Is this possible? What I currently have is a page that displays the page skeleton and then on button_click(), the rest of the page is rendered. I want to fire a button_click() event on code-behind without actually requiring the user to click on the button but can't seem to find good tutorials/articles regarding this approach.

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?

Textbox OnTextChanged And Button Click Event Not Firing?

May 20, 2010

I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
