I am having two web pages default.aspx and main.aspx. How to show main.aspx content in default.aspx. i need to embed the content in one part of the default.aspx
You shoud change Main.aspx to a usercontrol(.ascx) then you can include it like this
<%# Register TagPrefix="uc" TagName="Main" Src="~/Controls/Main.ascx" %>
<uc:Main id="main" runat="server" />
I believe you want to embed the content in an iframe.
So in default.apx, you should embed:
<iframe src="http://www.main.aspx"></iframe>
Using JQuery
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Load remote content into object element</title>
</head>
<body>
<div id="siteloader"></div>
<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<script>
$("#siteloader").html('<object data="http://tired.com/">');
</script>
</body>
</html>
For more reference
You have some choices here:
1. Use iframe HTML tag
2. Use UserControl (.ascx)
3. Use MasterPage

I have an large existing ASP.NET WebForms application. This application has a masterpage who manager security, navigation, ...
Pages developped are in a ContentPlaceHolder.
I would like to develop new pages in JS with web components. To use a web component on a page, it must be imported (<link rel="import" href="...">). This import must be on the <head> part of the page. In my case, the <head> is on the master page. So I have to import all the existing web components in the master page to be able to use them.
It does not sound like a very good idea.
How can I do it otherwise ?
Asp.Net lets you place ContentPlaceHolder in head tag. You can load the web components required by the page instead of loading them all in Master Page.
Master Page
<html>
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="cpHead" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="cpBody" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Web Form
<asp:Content ID="Content1" ContentPlaceHolderID="cpHead" runat="server">
<link rel="import" href="...">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="cpBody" runat="server">
</asp:Content>
Your HTML will look like
<html>
<head>
<title></title>
<link href="..." rel="import">
</head>
<body>
</body>
</html>
You would normally use RegisterClientScriptInclude. This will add the script file to the top of the page, but not in the <head>.
ClientScript.RegisterClientScriptInclude("myScript", "myJavaScriptFile.js");
If you really want it in the <head> you need to use a HtmlGenericControl
HtmlGenericControl genericControl = new HtmlGenericControl("script");
genericControl.Attributes.Add("type", "text/javascript");
genericControl.Attributes.Add("src", "myJavaScriptFile.js");
this.Page.Header.Controls.Add(genericControl);
It does not matter where you place this code (Master, Page, User Control). Aspnet will ensure they end up in the right place client side.
Question is pretty well stated in the title. Normally I would use <link... /> to reference my CSS Sheet but since I'm using a master page I don't have access to the Head Tag so how do I reference a specific CSS sheet on my ASPX page. I tried using <%# Import Namespace="Style.css" but no luck. Thanks for the help.
Just add a CSS ContentPlaceHolder with a default value in it.
Basically, the CSS file you specify as default will be included unless you override that placeholder with an tag from a child page.
Your Master Page should look something like this.
<head>
<asp:ContentPlaceHolder ID="Stylesheets" runat="server">
<link rel="stylesheet" href="/css/master.css" type="text/css" />
</asp:ContentPlaceHolder>
</head>
Then from any pages using that Master Page, you can simply override that with a different stylesheet.
On (example) AboutUs.aspx
<asp:Content ID="Content1" ContentPlaceHolderID="Stylesheets" runat="server">
<link rel="stylesheet" href="/css/Style.css" type="text/css" />
</asp:Content>
If you want to add a CSS stylesheet to any ASPX page, you should use PlaceHolders.
Master page: (in the section)
<asp:ContentPlaceHolder ID="HeadContent" runat="server">
</asp:ContentPlaceHolder>
ASPX Page:
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
// add your link here
</asp:Content>
just drag your style sheet to your master page.aspx and it will work for all your other forms
You have 3 possible solutions:
Add your link to the head tag of the master page's markup. If you do so, all the pages using the given master page will automatically use your css file.
Use a ContentPlaceHolder in the head tag of your master page. You can use the ContentPlaceHolder at your pages referencing the given master page and you can add your link tag inside the ContentPlaceHolder tag in the markup.
You can add your link tag using Javascrip/jQuery functions.
Although I went the code behind route below in my Page_Load event (VB), I'll give the correct answer to A.K as it seemed to answer the question better but just didn't suit my specific case.
Dim link As New HtmlLink()
link.Attributes.Add("href", Page.ResolveClientUrl("../Css/Generic-Form2.css"))
link.Attributes.Add("Type", "text/css")
link.Attributes.Add("rel", "stylesheet")
Page.Header.Controls.Add(link)
Append the link tag to the head using DOM manipulation.
I'm using ASP.NET with a master page containing a script manager. I want to add a javascript file to only one page, but all pages inherit from the master. What is the proper way to accomplish this?
thanks in advance
Add a script manager proxy to the page you wish to add the javascript to and then add the javascript reference using the script manager proxy
In the Master Page add a content container in the HEAD section, in your page put the Javascript tag inside the instance of that container.
EDIT - for d03boy
On MasterPage:
<head runat="server">
<asp:ContentPlaceHolder ID="HeadContent" runat="server" />
</head>
On ContentPage:
<asp:Content ID="LocalHeadContent" ContentPlaceHolderID="HeadContent" runat="server">
<script type="javascript" \>
</asp:Content>
For any content page that doesn't have something to include in the page header there's no need to even create the Content tag.
Can you just use the ClientScriptManager?
if (!Page.ClientScript.IsClientScriptIncludeRegistered("MyKey"))
{
Page.ClientScript.RegisterClientScriptInclude("MyKey", "~/js/script.js");
}
There are a couple of ways to accomplish what you are looking for.
1- put a content place holder in the section of your master page
<head runat="server">
<asp:ContentPlaceHolder runat="server" ID="JavascriptPlaceHolder">
</asp:ContentPlaceHolder>
</head>
and in the specific page you want to add a javascript file add:
<asp:Content ID="Content2" ContentPlaceHolderID="JavascriptPlaceHolder" Runat="Server">
<script type="text/javascript" src="myfile.js" ></script>
</asp:Content>
2- When you are not using Update Panels, use the ClientScript:
Page.ClientScript.RegisterClientScriptInclude("MyKey", "/myfile.js");
3- When using Update Panel and partial page rendering, use the ScriptManager object to register your javascript: (For a script that should be available for the onload event or at least be available when an update panel refreshes)
string javascript_string = "function myAlert(){ alert('me'); }";
ScriptManager.RegisterStartupScript(this, typeof(string), "MyKey", javascript_string, false);
Use the content place holder where you can, then use either other technique when you can't.
How to embed javascript into a content page?
Normally when we are using Master/Content style pages, we apply the css to Master page so every page child of the master page can use the style but I don't want this,I want I wanna apply css to content page directly instead of master page. Where should I put
<link rel="stylesheet" href="css/lightbox.css" type="text/css" media="screen" />
that reference code ?
Thanks in advance by the way.
Normally I put a content placeholder in the head section of the master page. That way any content page can add extra css/js/etc references to the head of the page.
In your master page put the following
<head>
... title, meta tags, js and css links ...
<asp:contentPlaceholder id="head" runat="server" />
</head>
Then in your pages you can include extra elements in the head using this
<asp:content contentplaceholderid="head" runat="server">
<link rel="stylesheet" href="css/lightbox.css" type="text/css" media="screen" />
</asp:content>
Put a content placeholder in the head portion of your master page. Not all content pages will need to place anything in it but this particular content page can place the CSS file you want to link.
You can't apply a style sheet to a content page only, it applies to the whole web page.
I have a page which has a masterpage. Do I put script and link tags inside the asp:content place holders or outside or does it matter.
When I put it outside, I get the following warning:
Only Content controls are allowed directly in a content page that contains Content controls.
I can see five (or 8) ways of doing it:
In the codebehind (.cs or .vb) using:
Scriptmanager.RegisterClientScriptinclude - using an absolute/relative path
Scriptmanager.RegisterClientScriptInclude - using an embedded resource
Scriptmanager.RegisterSlientScriptBlock - with your source inside
Adding it inline to your ASPX page in the designer
Sticking it inside the asp:content where the content lives inside the body tag.
Sticking it inside the asp:content where the content lives inside the head (You've said this isn't an option, so ignore this).
Adding it programmatically using the ScriptManager inside a control you use on the page as above.
"Only Content controls are allowed directly in a content page that contains Content controls" - did you forget the runat="server"?
If it's scripts and links for all pages, it should go outside any ContentPlaceHolders. If it's scripts and links for this page, it should go inside a Content inside the head. If it's default scripts, put it inside a head ContentPlaceHolder, and it can be replaced by the child page if needed. (VS usually complains about a ContentPlaceHolder in the head, but it works fine for me).
// master Page
<head runat="server">
<asp:ContentPlaceHolder id="head" runat="server">
<!-- Default scripts and CSS -->
<link rel="stylesheet" type="text/css" href="default.css" />
<script type="text/javascript" src="jquery.js"></script>
</asp:ContentPlaceHolder>
<!-- Mandatory scripts and css -->
<link rel="stylesheet" type="text/css" href="all.css" />
<script type="text/javascript" src="all.js"></script>
</head>
<body>
Master Page!
<asp:ContentPlaceHolder id="body" runat="server" />
</body>
// Child (no JQuery)
<asp:Content ContentPlaceHolderID="head" runat="server">
<link rel="stylesheet" type="text/css" href="default.css" />
<!-- Don't need JQuery -->
<script type="text/javascript" src="prototype.js"></script>
</asp:Content>
<asp:Content ContentPlaceHolderID="body" runat="server">
Child Page!
</asp:Content>
// Child 2 (with JQuery)
<asp:Content ContentPlaceHolderID="body" runat="server">
Child Page!
</asp:Content>
If you are referring to <asp:Content /> tags, you can't put anything outside of them in an .aspx page. So you're limited to putting them inside the <asp:Content /> tag. If you want <script /> and <link /> tags you need to either put a <asp:ContentPlaceHolder /> in the <head> of your master page, or add them dynamically via the Page's Controls collection.
Outside. Tthe inside of the ContentPlaceholders is going to be replaced with content from your pages anyhow so it doesn't make much sense to put anything in there.
outside. in the master page
The place holders are the wrapping controls for pages which descend from master pages.
Use asp.net scriptreference tag in master page to add reference to javascript file and you will be able to access all you need in the javascript file as if you would have added to the local page.
