javascript pageLoad function not firing in asp.net Site.Master

javascript pageLoad function not firing in asp.net Site.Master - c#

I am trying to get this javascript function to fire every time there is a postback in my ASP.net project using c#. I read online that if you create a pageLoad() function in Javascript, it will fire every time on a postback. I can't get it to fire. Here is all the code in my Site.Master file.

I would appreciate any help.
Thanks

You're already using jQuery's $(document).ready, just add your code there as well. It will run every time page reloads:
$(document).ready(function () {
$('#MainContent_ckbIncludeWeight').click(function () {
if (this.checked) {
$('#MainContent_txtPalletWeight').show();
$('#MainContent_txtPalletWeight').val('40');
$('#MainContent_txtPalletWeight').after("<span id='pound'>#</span>");
}
else {
$('#MainContent_txtPalletWeight').hide();
$('#MainContent_txtPalletWeight').val('');
$('#pound').remove();
}
});
// Originally from function pageLoad()
if ($('#MainContent_ckbIncludeWeight').checked) {
$('#MainContent_txtPalletWeight').show();
console.log('it is checked!');
alert('it is checked!');
}
if (true) {
console.log('fire!');
alert('fire!');
}
});

You have to have ScriptManager on page in order for pageLoad() to work.
There is however no need for adding it, if you just want to run some script on every postback.
You can do something like putting this:
<asp:PlaceHolder ID="phPageLoad" runat="server">
<script type="text/javascript">
if ($('#MainContent_ckbIncludeWeight').checked) {
$('#MainContent_txtPalletWeight').show();
console.log('it is checked!');
alert('it is checked!');
}
if (true) {
console.log('fire!');
alert('fire!');
}
</script>
</asp:PlaceHolder>
into your master page and in codebehind of master page add this to Page_Load:
phPageLoad.Visible = Page.IsPostback;

c# jquery simple dialogbox

I am new to C# and JQuery. I try to add jquery to a C# WebForm project.
What I want to do is this:
Add a button to a webform.
If that button is clicked serverside then display a JQuery dialogbox
This is the code that I have - if I click the button nothing happens.
I wonder where the problem is....
.aspx file:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="frmMain.aspx.cs" Inherits="Dialog_YES_NO_mit_JQuery.frmMain" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js' type="text/javascript"></script>
<script type="text/javascript">
function ShowPopup(message) {
$(function () {
$("#dialog").html(message);
$("#dialog").dialog({
title: "jQuery Dialog Popup",
buttons: {
Close: function () {
$(this).dialog('close');
}
},
modal: true
});
});
};
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
Dialogbox using JQuery<br />
<br />
<asp:Button ID="btnDemo1" runat="server" OnClick="btnDemo1_Click" Text="Demo1" />
<br />
</div>
</form>
</body>
</html>
.aspx.cs file :
public partial class frmMain : System.Web.UI.Page
{
protected void btnDemo1_Click(object sender, EventArgs e)
{
string message = "Message from server side";
//ClientScript.RegisterStartupScript (this.GetType(), "Popup", "ShowPopup('" + message + "');", true);
ClientScript.RegisterClientScriptBlock(this.GetType(), "Popup", "ShowPopup('" + message + "');", true);
}
}
}

Here's a complete example that works:
You need to add a reference to jQuery UI library after the reference to jQuery as this is where the dialog logic is defined
You need to add a reference to the jQuery UI CSS file to enable the modal popup styling.
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js' type="text/javascript"></script>
<script src="http://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.4/jquery-ui.css" rel="stylesheet">
<script type="text/javascript">
function ShowPopup(message) {
$(function () {
$("#dialog").html(message);
$("#dialog").dialog({
title: "jQuery Dialog Popup",
buttons: {
Close: function () {
$(this).dialog('close');
}
},
modal: true
});
});
};
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
Dialogbox using JQuery<br />
<br />
<asp:Button ID="btnDemo1" runat="server" OnClick="btnDemo1_Click" Text="Demo1" />
<br />
<div id="dialog"></div>
</div>
</form>
</body>
Output:

here an example that works for me :
code behind :
protected void ShowDialogClick(object sender, EventArgs e)
{
ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), Guid.NewGuid().ToString(), "ShowDialogJS();", true);
}
aspx :
<script type="text/javascript">
function ShowDialogJS() {
jQuery("#dialog").dialog();
}
</script>
<asp:Button runat="server" ID="btnShowDialog" Text="Show Dialog"
OnClick="ShowDialogClick"></asp:Button>
EDIT :
I have two js files for jQuery :
<script src="ressources/jQuery/scripts/jquery-1.11.4.js" type="text/javascript"></script>
<script src="ressources/jQuery/scripts/jquery-ui-1.11.4.js" type="text/javascript"></script>

try this
aspx
`
<form id="form1" runat="server">
<div>
Dialogbox using JQuery<br />
<div id="dialog"></div>
<br />
<asp:Button ID="btnDemo1" runat="server" OnClick="btnDemo1_Click" Text="Demo1" />
<br />
</div>
</form>
`
added
<div id="dialog"></div>
i also added javascirpt files

<script src="http://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>

C# - Data from _.aspx to _.cshtml with a form

I'm new to C# - ASP.NET and I'm trying to drop data ,from a filled form, from .aspx to .cshtml.
I made a form with three TextBoxes and a Button, a method for the "onClick". This method set the value of ViewData (name,date,user) with the values of the three TextBoxes. And I want to collect these value on the page targeted by the form.
I do not get any error but ViewData(name,date,user) seems to be empty.
Here's my code :
CSHTML
#{
ViewBag.Title = "Consulter";
}
#Html.Partial("MenuBar")
#Html.Partial("Connexion")
#ViewData["name"]
<style type="text/css">
...
</style>
...
<h2>...
ASPX
<%# Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<script language="C#" runat="server">
public void Ajouter(Object sender, EventArgs e)
{
ViewData["name"] = dateForm.Text;
ViewData["date"] = dateForm.Text;
ViewData["user"] = userForm.Text;
}
</script>
<!DOCTYPE html>

<asp:Label runat="server" ID="label1" />
</div>
</form>
</div>

If you know how to solve it or if you have another way to do it, it would be amazing :)
Thank you in advance.

Why doesn't returning false from OnClientClick cancel the postback
In this case a handler for the one more click event was registered via jquery ..I think it is not in my case
ASP.NET OnClientClick="return false;" doesn't work
there should not be a click event handler (registered via jquery) which returns true .whats mean by that ?Does it mean that i need to remove onClick function ... i dont wanna do it
I also tried other suggested Code :
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="if (!x()) return
false;" OnClick="Button1_Click" />
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="javascript:return
x();"OnClick="Button1_Click" />
they are also not working
Plese suggest

This worked for me...
.aspx page
<asp:Button id="btn" runat="server" Text="Button" onclientclick="if (!x()) { return false; }" onclick="btn_Click" />
<script type="text/javascript">
function x() {
return false;

Reference Help
Update from an external javascript file working code

Hope it helps..!!

You can also put all the code in single file. Attaching handler directly from jQuery
jQuery(document).ready(function () {
AttachDeleteButtonHandler();
});
function AttachDeleteButtonHandler() {
var btnDelete = $("div[class='page']").find("table[id$='tblButtons']").find("input[id$='btnDelete']");
btnDelete.click(
function () {
return ConfirmDelete();
}
);
}
function ConfirmDelete() {
var msg = $('div[id="hdnElements"]').find('span[onclick*="translatedMsgText"]').text();
if (confirm(msg)) {
return true;
}
else {
return false;
}
}

File upload code works in Chrome and Mozilla but not in ie 8,9

Here is the server side c# code
protected void btnUpload_Click1(object sender, EventArgs e)
{
HttpPostedFile file = Request.Files["btnFileUpload"];
if (file != null && file.ContentLength > 0)
{
string fname = Path.GetFileName(file.FileName);
file.SaveAs(Server.MapPath(Path.Combine("~/App_Data/", fname)));
}
}
This code works good in Chrome and Mozilla but in ie 8,9 Request.Files["btnFileUpload"] gets null.
Here is the html ...
<form id="form1" runat="server" enctype="multipart/form-data">
<div class="fileName">
</div>
<div id="plus" class="uploadPlusBtn">
</div>
<input type="file" id="btnFileUpload" runat="server" />
<asp:Button ID="btnUpload" runat="server" OnClick="btnUpload_Click1" Text="Upload" />
</form>
And the added jQuery
$(function () {
var wrapper = $('<div/>').css({ height: 0, width: 0, 'overflow': 'hidden' });
var fileInput = $('#btnFileUpload').wrap(wrapper);
$('#plus').click(function () {
fileInput.click();
});
});

I have IE 8 and your code is working fine for me, Request.Files["btnFileUpload"] is returning HttpPostedFile. Here is the .aspx code:
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script>
$(function () {
var wrapper = $('<div/>').css({ height: 0, width: 0, 'overflow': 'hidden' });
var fileInput = $('#btnFileUpload').wrap(wrapper);
$('#plus').click(function () {
fileInput.click();
});
});
</script>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data">
<div class="fileName">
</div>
<div id="plus" class="uploadPlusBtn">
</div>
<input type="file" id="btnFileUpload" runat="server" />
<asp:Button ID="btnUpload" runat="server" OnClick="btnUpload_Click1" Text="Upload" />
</form>
</body>
</html>

Pagemethods in popuppanel does not load the second time in IE9

I have a main page which has some pagemethod called to perform some activities. A popuppanel(popuppanel content page also have pagemethods) is used within this main page to show some details. If the same is executed multiple times (i.e., opening the popup panel many times), it is working in all other browsers other than IE9 (working even in IE8). However, first time execution is successful. The code that is being used is provided below.
Scriptmanager used as follow:
<ajaxToolkit:ToolkitScriptManager runat="server" ID="TSCM1" EnablePageMethods="true" />
Script In Main Page:
function Clkd(){
var ppnl=document.getElementById("if1");
ppnl.src="Test1.aspx";
$find('<%= MPE.ClientID %>').show();
}
function Clkd2(){
var ppnl=document.getElementById("if1");
ppnl.src="";
$find('<%= MPE.ClientID %>').hide();
}
$(document).ready(function(){
PageMethods.mainPageMethod("MainTest",cbackfn);
});
function cbackfn(str){
alert(str);
}
Page method:
[System.Web.Services.WebMethod(EnableSession = true)]
public static string mainPageMethod(String mainStr)
{
return mainStr + " Ok";
}
Test1.aspx page Details (this is the page loaded inside the popup panel):
Script code below :
$(document).ready(function(){
PageMethods.Testpm("Test",fnd);
});
function fnd(str){
alert(str);
}
Page method:
[System.Web.Services.WebMethod(EnableSession = true)]
public static string Testpm(String alrt)
{
return "Ok";
}
The following error is thrown if the same is executed the second time (in IE9 only)
SCRIPT5007: Unable to set value of the property '_UpdateProgress': object is null or undefined
ScriptResource.axd?........
SCRIPT5007: Unable to get value of the property 'WebServiceProxy': object is null or undefined
Test1.aspx, line 66 character 1
SCRIPT5007: Unable to get value of the property 'DomElement': object is null or undefined
ScriptResource.axd?......, line 2 character 18851

Test1.aspx, line 97 character 122
SCRIPT438: Object doesn't support property or method 'Testpm'
Test1.aspx, line 11 character 4
Important Note: if main page does not have any pagemethods then its working fine.
please help me out from this issue..

You should have added relevant HTML, that might have helped others to help you out.
Well I used your code and added missing code and when I runt it, it is working fine in all browsers including IE9.
Please find below code:
Main Page (Default.aspx):

$find('<%= MPE.ClientID %>').show();

Test.aspx.ce (Webmethod):
[System.Web.Services.WebMethod(EnableSession = true)]
public static string Testpm(String alrt)
{
return "Ok";
}
I hope it helps!

U can try with different popUp
for Example:
asp:ModalPopupExtender also available in ajaxtoolkit
jquery dialog popup.

I will prefer you to go with jquery dialog popup instead of ajaxpopup panel using the same web method in c# and jquery code you have written.

Use ClientIdMode="Static" on the MPE and use MPE id directly in $find().
ASPX Code:
<asp:ModalPopupExtender ID="modalpopup" ClientIDMode="Static" runat="server" CancelControlID="btnCancel"
OkControlID="btnOkay" TargetControlID="Button1" PopupControlID="Panel1"
Drag="true" >
</asp:ModalPopupExtender>
Javscript code:
$find('modalpopup').show(); // to show popup
$find('modalpopup').hide(); // to hide popup

IE9 has problem with pagemethods while having pagemethods in bothpage (mainpage,popuppanelpage).
you can use pagemethods in webservice(.asmx) file
i tried like below:
defaultpage.aspx
<head id="Head1" runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>

}
function objFailed1(data) {
fnd123(data);
}
function objGot1(data) {
fnd123(data.d);
}
function Clkd(){
var ppnl=document.getElementById("if1");
$.ajax({
url: "Testser.asmx/GetData",
contentType: "application/json; charset=utf-8",
dataType: "json",
data:'{"FileName":"Data from default page"}',

});
ppnl.src="Test1.aspx";
$find('MPE').show();
}
