I am newer to asp.net. I have created gridview in that i addedd column and rows manually .i am not used any datasource. In footerpage i added a button when the user clicks the button new the row will have to add I also written a code for adding new row but on which event i have to call that procedure.
View 1 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.
Here's the ASP code:

I am a bit new to the asp.net/jQuery game, and I seem to be having difficulty. I am using colorbox to make a modal window popup, and I want an upload picture form on that modal window. I have a button to open up the add photo form:
<a href="#" class="addpicture">Add/Edit picture(s)</a><br />
<script>
$(document).ready(function () {
$(".addpicture").colorbox({ width: "50%", inline: true, href: "#page1" });
[code]...
However when I push the button nothing happens, the text-box ain't updated.
I also wounder how i can access the data inside the DataList so that I can manipulate it inside the "DataList1_ItemCommand" function.
<p>
<asp:TextBox ID="NameTextBox" runat="server" CssClass="textEntry"
TextMode="SingleLine" Rows="0" Height="20px" Width="250px" Enabled="False"></asp:TextBox>
<asp:DataList
ID="DataList1"
runat="server"

I'm facing a weird issue...My button events are not firing :(I'm using the 3.5 .net framework and I've already tried to run aspnet_regiis -c, clear the browser temp files, use windows integrated authentication, but nothing works...this is the cenario:
- windows server 2003
- app migrated from .net framework 1.1 (which was working fine) to .net framework 3.5
- IE8
basically i have a few check boxes. if checkbox 1 is checked, i will assign a string to a variable. so i will have each check boxes having their own strings which will be saved into a text file.only when a button is clicked, then these strings will be saved into text file.i did this:
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
string masterbuild1 = "Exec_Build_starting_mail";

m using ajax control tab container, in which i have placed 5 tab panels....
in first tab panel submit button is woking fine,but in 2nd tabPanel button is giving problem,its not firing even a single event...
I'm using an AjaxToolKit Accordion Control and when I put a button in, the "onclick" event is not raising. When I use a dropDownList, if I select "autoPostBack", the event raises normaly (instead, nothing occours). But with buttons I cannot define the "autoPostBack" (its implicit?).
View 1 RepliesI have the problem that when i´m adding my usercontrol to my default page the events do not fire. I already know that I had to add the usercontrol as soon as possible to the lifecycle, but I can´t because I know the number of buttons after clicking on my default button.
code:
my default.aspx.cs page
protected override void OnInit(EventArgs e)
{
if (!IsPostBack)
{
addPruefstation aP = (addPruefstation)this.LoadControl("addPruefstation.ascx");
aP.ID = "ucPruefstation";
Session["ucPruefstation"] = aP;
}
base.OnInit(e);
}
protected void bApply_Click(object sender, ImageClickEventArgs e)
{
int anz;
Int32.TryParse(((TextBox)tablePruefstand.FindControl("tbPruefstandstationen")).Text, out anz); //here i´m getting the number of buttons
Session["anzStation"]=anz;
addPruefstation aP = (addPruefstation)Session["ucPruefstation"];
aP.anz = anz;
Session["ucPruefstation"] = aP;
phPruefstation.Controls.Add(aP);
}
my usercontrol.acsx.cs:
public int anz;
protected override void OnInit(EventArgs e)
{
for (int i = 0; i < anz; i++)
{
tcButton=new TableCell();
trPruefstation = new TableRow();
tcEmpty = new TableCell();
tcLabel = new TableCell();
tcTextbox = new TableCell();
tcLabel.Controls.Add(new LiteralControl("Anzahl Leaks"));
tcTextbox.Controls.Add(new TextBox() { ID = "Leak" + i, Text = "0", AutoPostBack = false });
ImageButton imgButton = new ImageButton() { ID = "" + i, ImageUrl = "~/Img/1rightarrow-256.png", Height=15};
imgButton.Click += new ImageClickEventHandler(imgButton_Click);
tcButton.Controls.Add(imgButton);
trPruefstation.Cells.Add(tcEmpty);
trPruefstation.Cells.Add(tcLabel);
trPruefstation.Cells.Add(tcTextbox);
trPruefstation.Cells.Add(tcButton);
tablePruefstation.Rows.Add(trPruefstation);

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?
The if (!Page.IsPostBack) is always false went the page loads after i click a linkbutton and it never goes into the linkbutton event. Googled as much as I can. I am kinda new to asp
This is the code that i have in server:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
SetDefaultView();
}
}
private void SetDefaultView()
{
MultiView1.ActiveViewIndex = 0;
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 0;
}
protected void LinkButton2_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 1;
}
// and below..
<td>
<asp:LinkButton ID="LinkButton1" runat="server"
onclick="LinkButton1_Click">Tab1</asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LinkButton2" runat="server" onclick="LinkButton2_Click">Tab2</asp:LinkButton>
</td>
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.
I have a couple of buttons controls in my gridview pagetemplate. when i click in next page button it is calling wrong events calling my dropdownlist_selectedIndexChange event?
I am trying to fire one event out of two avalible events based on a check box selectoin, I have already registered the two events in the page_load() and i check if the check box is checked (checkbox is located within a gridview) then i un-register one of the events and just keep one events registered as following(Only relative part is shown):
[Code]....
I am trying to fire one event only based on the checkbox selection. I tryed to debug and noticed that, in fact, both evetns always get fired starting first with Button_SessionStartOrEnd_StartSessino and then Button_SessionStartOrEnd_EndSessino. So how can i fire one event only? please note that my code to check if the ckeckbox is checked within the girdview works fine.
For some reason I can't get the button event to fire...
This is my Accordion:
[Code]....
I dynamically add the panes and buttons...
[Code]....
These two should get fired - but they dont:

I read somewhere that I should add the button to the UpdatePanel

But when I do I get this error :
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
Button b = (Button)sender;
Label tfive = (Label)FormView1.FindControl("five");
Label ttwo = (Label)FormView1.FindControl("two");

I have a master page with a menu on it. I have found now two pages out of dozens where for some reason the master page events aren't firing. I've put a break point in there and it never hits it. Is there something that could cause a disconnect between the page and the master page events? Really weird it happens in Chrome and IE but they fire correctly in Safari.
View 12 RepliesI Simply drag a button from the toolbar onto a new page with a master page and a title, double click it so that I enter the Button1_Click function and sets a breakpoint and add some random code. The breakpoint nor the code never fires. I've tried this on several different pages and controllers, but with the same results: The page reloads, but no code is run. I Have Tried:
Ive tried with three different webbrowsers with all plugins disabled. I've tried to turn of Causes Validation, - Nothing changes. I've tried to clean and Rebuild the project, - Still nothing. I've tried to create a whole new project, -Does'nt work there either. Other Information: A RadioButtonList OnDatabound Event works, but whenever i try to do a Button or ImageButton click event the code for the event never fires. Ive programmed several webapplications in other versions of visual studio and ASP.NET but I have never encountered this problem before.
Breakpoints work in other parts of the code and the compile settings is set to DEBUG.

* ASP.NET 4

Am I supposed to file a bug report or does anyone out there have a solution?
That doesn't make any sense at all but what I mean is, if you've got a button for example which takes say 10 seconds to complete whatever is in the button click routine, and somebody else on a different computer clicks the same button just after, is it possible for that second button click routine to wait until the first one is complete? And most importantly is it something fairly simple to do? I'm sure I accidently found some information on this when searching the web for something else but I can't remember what I was searching for before and can't find it now
View 7 RepliesI have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">

<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />

<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
