I have folder structure like this for asp.net site :
now i run the site and result is like this :
here i am able to see the image "6".
now on click on : button , i am opening another page : dashboard.aspx:
$(document).ready(function () {
$("#btnDashBoard").on("click", function () {
debugger;
window.location.href = "dashboard/dashboard.aspx";
return false;
});
});
here i am not able to see my image, why?
my site.master html is like this :
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$(document).ready(function () {
$("#btnDashBoard").on("click", function () {
debugger;
window.location.href = "dashboard/dashboard.aspx";
return false;
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="btnDashBoard" type="button" value="button" />
</div>
<div>
<img src="../Images/orderedList6.png" alt="" />
</div>
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
You should let ASP.NET help you figure out the paths. There's a utility method on every Control named ResolveClientUrl(). If you pass it the virtual path to a file, it will resolve its full path.
You can use it right in the src attribute for your <img> tag:
<img src='<%= Path.ResolveClientUrl("~/Images/orderedList6.png") %>' alt="" />
I had a problem which was, my path was for example: https://mysite/projects/index
And my html stored in database had an image with this src: ~/Images/myimg.png
So the path i was getting for the image was:
https://mysite/projects/index/~/Images/myimg.png
I just removed the "~" from my source and everything was solved, it lead to image path which was: https://mysite/Content/Images/myimg.png
Hope this helps

I'm trying to get the value from a hiddenfield but I'm getting an undefined alert. What am I doing wrong?
// Masterpage
...
<body>
<div class="container">
<asp:ContentPlaceHolder ID="MasterContent" runat="server"></asp:ContentPlaceHolder>
</div>
<script>
$(document).ready(function () {
alert($('#hiddenPersonId').val());
});
</script>
</body>
// Default.aspx
<asp:Content ID="Content" ContentPlaceHolderID="MasterContent" runat="Server">
<asp:HiddenField ID="hiddenPersonId" runat="server" Value="1" />
</asp:Content>
I tried other solutions but these are also not working:
alert($("#<%= hiddenPersonId.ClientID %>").val());
You could try setting ClientIDMode to static if you're .net 4+. You'll want to check that it is defined first. If you want/need the js to be on master page.
<script type="text/javascript">
$().ready(function () {
alert($('#hdnPersonId').val());
});
</script>
<asp:HiddenField ID="hdnPersonId" Value="1" runat="server" ClientIDMode="Static" />
It will not work from master page. You need to call it from Default.aspx or try
$('[id*="hiddenPersonId"]')
on master page but other pages that uses this master page should not have any control that contains hiddenPersonId in its id
I have a user control called header.aspx. In my user control if I do this it will work.
<script type="text/javascript">
function greeting(){
Alert("hi");
}
</script>
<asp:button id="button1" OnClientClick="greeting" /> </asp:button>
I am using this user control in a page called default.aspx. I tried using src="~scripts/foo.js". If I do that it does not work. The question is pretty simple I guess. How would I call a java script function in a user control which is stored in an external location( not in the page. Located in the scripts folder). Thanks in advance.
As I can understand this is clearly a path issue.
Just follow these steps might help you.
Create a .js file first. Put your code and save it in the folder you want it to.
Now Drag and Drop the js file inside the head section of your html code from the Solution Explorer window. This will give you the correct path for the js file.
The above steps is what I follow, when I create an external js file for my controls.
Also make sure you call your function in this manner also suggested by others Else your function won't get call:
<asp:button id="button1" OnClientClick="greeting();" /> </asp:button>
Just use the code below:
<script src="<%: ResolveUrl("~/Scripts/foo.js") %>"></script>
Script: test.js
function greeting() {
alert("hi");
return false;
}
user control: <asp:Button ID="button1" OnClientClick="return greeting()" runat="server" Text="click" />
Page:
<head runat="server">
<title></title>
<script src="test.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:temp ID="temp" runat="server" />
</div>
</form>
</body>
</html>
This should work now.
<asp:button id="button1" OnClick=" javascript : greeting();" /> </asp:button>
try to use it. havent trie but i think it should work.
First of all you need to create a seprate javascript file and then add this in your page in this way. add this tag in the tag of your page.
use
OnClientClick="greeting()"
you missed "()" in OnClientClick="greeting"
Please see the whole html code:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="scripts/foo.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:button id="button1" runat="server" OnClientClick="greeting()" Text="hit" />
</div>
</form>
</body>
</html>
Thanks.
External javascript file reference:
<script src="yourpath/yourfilename.js"></script>
Button Control
<asp:Button ID="button1" OnClientClick="greeting();" runat="server" Text="click" />

You will need to use a client side javascript effect, Most likely with jQuery and load the pages using ajax then slide the page in after it is loaded. I found this Project that looks like it will do what you want and here is a sample from a tutorial.
<script type="text/javascript">
$(document).ready(function() {
$("body").css("display", "none");
$("body").fadeIn(2000);
$("a.transition").click(function(event){
event.preventDefault();
linkLocation = this.href;
$("body").fadeOut(1000, redirectPage);
});
function redirectPage() {
window.location = linkLocation;
}
});
</script>
And here is how you load a page via ajax from the jQuery website.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>load demo</title>
<style>
body {
font-size: 12px;
font-family: Arial;
}
</style>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body>
<b>Footer navigation:</b>
<ol id="new-nav"></ol>
<script>
$( "#new-nav" ).load( "/ #jq-footerNavigation li" );
</script>
</body>
</html>
I have a ASP.NET Application with a master site and content sites. in one of this content sites I have a Div with Controls and I want to try it make draggable with jQuery but I don't know how I can to this in ASP.NET because of the Control Id in asp.
here is my code:
master site:
...
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<link href="Styles/jquery-ui.css" rel="stylesheet" type="text/css" />
<script src="Script/jquery-1.8.2.js" type="text/javascript"></script>
<script src="Script/jquery-ui.js" type="text/javascript"></script>
<script>
$(function () {
$("#create_box").draggable();
});
</script>
</head>
<body>
<form id="mainform" runat="server">
<div class="gastzugang">
<asp:ContentPlaceHolder ID="lw_header" runat="server">
<!--Header-->
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="lw_content" runat="server">
<!--Content-->
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="lw_footer" runat="server">
<!--Footer-->
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
My Content Site:
<%# Page Title="" Language="C#" MasterPageFile="~/master.Master" AutoEventWireup="true" CodeBehind="CreateUser.aspx.cs" Inherits="lw_gastzugang.CreateUser" %>
<asp:Content ID="Content2" ContentPlaceHolderID="lw_content" runat="server">

I want to this:
http://jqueryui.com/droppable/
Just use jQuery UI draggable.
Make
ClientIDMode="static" in the asp.net Tag
Or Use
<script type="text/javascript">
$('#'+'<%=lw_content.ClientID%>').draggable();
</script>
You could take a look at hammer.js which covers a 'drag' style event:
https://github.com/EightMedia/hammer.js
The drag example there is at:
http://eightmedia.github.com/hammer.js/drag/
Now I don't know too much about ASP.NET but what I would try is applying the drag behaviour to anything with a .draggable class.
Hope that helps a little!
I have a Page that is associated with a master page. In the master page, I put the css links in the head section and I put the jquery script tag and the script that contains the function to toggle the grid, but when it is not working. Looks like it is not even calling showhide when I click on an item.
Here is a snippet of the master page:
<head runat="server">
<title></title>
<link href="MainLayout.css" rel="stylesheet" type="text/css" />
<link href="ajaxtab.css" rel="stylesheet" type="text/css" />
<link href="dialog.css" rel="stylesheet" type="text/css" />
<link href="grid.css" rel="stylesheet" type="text/css" />
<link href="pager.css" rel="stylesheet" type="text/css" />
<link href="subgrid.css" rel="stylesheet" type="text/css" />
<script src="jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
//master: id of div element that contains the information about master data
//details: id of div element wrapping the details grid
function showhide(master, detail) {
//First child of master div is the image
var src = $(master).children()[0].src;
//Switch image from (+) to (-) or vice versa.
if (src.endsWith("plus.png"))
src = src.replace('plus.png', 'minus.png');
else
src = src.replace('minus.png', 'plus.png');
//Set new image
$(master).children()[0].src = src;
//Toggle expand/collapse
$(detail).slideToggle("normal");
}
</script>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
Here is the div that contains the showhide function in the onclick event in the aspx page:
<div class="searchgroup"
id='<%#String.Format("master{0}",Container.DataItemIndex)%>'
onclick='showhide(<%#String.Format("\"#master{0}\"",Container.DataItemIndex)%>
,
<%#String.Format("\"#detail{0}\"",Container.DataItemIndex) %>)'>
<asp:Image ID="imgCollapsible"
CssClass="first"
ImageUrl="plus.png"
Style="margin-right: 5px;"
runat="server" />
<span class="searchheader"><%#Eval("Business")%></span>
</div>
Here is html it generates for the master and detail div:
//master div
<div class="searchgroup"
id='master0'
onclick='showhide("#master0","#detail0")'>
<img id="ctl00_ContentPanel_gvMaster_ctl02_imgCollapsible"
class="first" src="plus.png"
style="border-width:0px;margin-right: 5px;" />
<span class="searchheader">ABC</span>
</div>
//details div
<div id='detail0' class="searchdetail">
<div>
<table class="searchgrid"
id="ctl00_ContentPanel_gvMaster_ctl02_gvDtails">
<tr>
<th>Status</th>
<tr class="searchrow">
<td>2</td>
</tr>
</table>
</div>
</div>
I could not get the JQuery working and I was running out of time, so for now I decided to use the collapsible panel externder from the ajax control toolkit. When I get time, I will investigate the JQuery Issue, Thanks for all your suggestions so far. If anyone has any more, please let me know.
Your javascript is throwing an error at src.endsWith("plus.png") because there is no built in endsWith function in js. replace that with src.substr(-8) == "plus.png" instead and it works:
<script type="text/javascript">
//master: id of div element that contains the information about master data
//details: id of div element wrapping the details grid
function showhide(master, detail) {
//First child of master div is the image
var src = $(master).children()[0].src;
//Switch image from (+) to (-) or vice versa.
if (src.substr(-8) == "plus.png")
src = src.replace('plus.png', 'minus.png');
else
src = src.replace('minus.png', 'plus.png');
//Set new image
$(master).children()[0].src = src;
//Toggle expand/collapse
$(detail).slideToggle("normal");
}
</script>

src = src.replace('plus.png', 'minus.png');
else
src = src.replace('minus.png', 'plus.png');
//Set new image

" Looks like it is not even calling showhide when I click on an item." If you simplify the function with just an alert() function, does it work.
The code looks fine to me. Maybe there is some id mismatch.
You may check if jquery's path is correct in your page (that which uses this master page).
To be sure if its calling showhide() you can use Firebug in Firefox with a breakpoint in the function.
Also, it will give you more clues to debug and guess what is going wrong.
The code seems to be ok to me, too.
just a thought, if you right click view source on the browser, do you see the jquery path correctly? my experience tells me you need to resolve javascript urls on master pages (it works fine for css, but not js files)
<script src="<%= ResolveUrl("~") %>jquery-1.3.2.min.js" type="text/javascript"></script>
