ASP.Net C# Master Site - c#

I have a question about the ****.Master Site a in ASP.NET with C# (WebForms).
I've created a Site.Masters File with a lot of differente Placeholders inside. So the question is - is it possible to fill the Placeholders from different .aspx Files?
.Master Page:
<asp:ContentPlaceHolder ID="MainHeader" runat="server">
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="MainFooter" runat="server">
</asp:ContentPlaceHolder>
</div>
Now i would do something like this:
Adding some Content to the Main Header - the Content is represented in a file called mainHeader.aspx
Adding some Content to the Main Content - the Content is represented in a file calle mainContent.apsx
Is this possible or is there a solution for my plan? I would like to create a modular and flat structure of my .NET Project.
Thanks for your help - best regards

No, that's not how Master Pages work.
When the user/client requests an individual content Page, that Page is merged with the Master Page. The Master Page can not be called by the user/client.
I believe User Controls are what you are looking for.

You can do what you want by using jquery.load(), here is the documentation http://api.jquery.com/load/, however i think what you are doing is not the way to procede, in order to do what you want i suggest yo to do this:
Create User Controls, one for each master ContentPlaceHolder, then in your master, add each one of this and initiate them.

verify content control's ContentPlaceHolderID attribute in the content page

I am a new ASP.NET developer. I am making development using C#. I removed some default contents from that I am getting these error notification as attached in screen shot can anybody look at and give me a solution also some one inform me from where .NET pages control header and footer so I can make modification there.
Here is the complete error heading text:
"Cannot find ContentPlaceHolder 'MainContent' in the master page '/Site.Master', verify content control's ContentPlaceHolderID attribute in the content page."
Remove asp:Content ContentPlaceHolderID="MainContent" from your child pages or Add <asp:ContentPlaceHolder ID="MainContent" runat="server"> into your Master page.
There is no ContentPlaceHolder named 'MainContent' in your master page,
A content place holder should be in your Master page like this:
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
And child pages like this:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
</asp:Content>
When you have a child page that inherits from a master page ContentPlaceHolder should match between them.
So if you masterpage declare that every child should fill its Box1 Box2 and Box3containers every
child page that is linked to it (MasterPageFile="~/MasterPages/Site.master") must contain this references <asp:Content runat="server" ContentPlaceHolderID="Box1"> even if empty.
In your case you have declared a box name that Master page doesn't has
update
looking at your code I can suspect that you have linked the master page in a wrong way.
Change the attribute of your page and be sure that the path is correct
MasterPageFile="~/MasterPages/Site.master"
if it doesn't work try this
If the page is empty delete it and recreate aspx page with master page, after you select the master page the child page will be created with the right contentplaceholders.

master page in umbraco

i'm programming in asp.net with umbraco and have a problem with master page.
i made a master page then added a web user master page that link in my default page.
at run time project in umbraco when i click on link saw this error :
Page not found
No umbraco document matches the url
'http://localhost:20771/WebForm1.aspx'
umbraco tried this to match it using this xpath query'/root/*
[#urlName = "webform1"] | /root// [#urlName = "webform1"]')
This page can be replaced with a custom 404 page by adding the id of
the umbraco document to show as 404 page in the
/config/umbracoSettings.config file. Just add the id to the
'/settings/content/errors/error404' element.
For more information, visit information about custom 404 on the
umbraco website.
This page is intentionally left ugly ;-)
i search in web and did not find any solution about it.
Check that your master page shows up in the admin area via Settings > Templates.
Then, check that your content page (in the admin Content section) has a template defined (under "Generic properties"). If it doesn't, and it doesn't let you select a template, then you need to allow that template to be used for that particular node type.
Go to Settings > Document Types, select your node type, and under "Allowed templates", select the template that you wish to us for the page (you may select a nested masterpage, it should still work just fine) - also make sure that the "Default allowed template" underneath is selected to your chosen template. Once you have hit "Save", go back to your node in the Content section, go to the "Generic properties" tab, and select the template you wish.
Umbraco lets you use any number of masterpages for rendering a content node. When creating new nodes, you then choose the template you wish to use (or use the default, as specified by following the above instructions).
You can also force a different template to be used at runtime, using the ?altTemplate=MyTemplateName querystring option on your page URL - handy for mobile sites, RSS views, and suchlike.
In Master.master page (it's general master page.) you can locate asp:ContentPlaceHolder
please attention to this code.Perhaps it's help you.
<div style="vertical-align: top;">
<umbraco:Macro ID="Macro1" Alias="NavigationControl" runat="server"></umbraco:Macro>
</div>
***<div>
<asp:ContentPlaceHolder ID="DefaultPageContent" runat="server">
</asp:ContentPlaceHolder>
</div>***
<div>
<asp:ContentPlaceHolder ID="TextPageContent" runat="server">
<!-- Insert default "ContactUsContent" markup here -->
</asp:ContentPlaceHolder>
</div>
<div>
<asp:ContentPlaceHolder ID="AtAGlanceContent" runat="server">
</asp:ContentPlaceHolder>
</div>
<div id="footer">
<uc6:FooterControl ID="FooterControl1" runat="server" />
</div>

C# .NET include file

I searched a way to include a file in a web application (like a menu, so I won't have to edit it on all pages when applying changes), but haven't found something as simple as
<?php include "Menu.html"; ?>
Can you please help?
Have you looked into Master Pages? They would certainly help you add the same layout across several pages.
Or perhaps you want a reusable User Control (that you write yourself)?
We don't use "include page" in asp.net, even though it is possible (with a different syntax of course). Instead, have a look at Master page concept.
MasterPages allow you to maintain a parent/child relationship between a master page which contains content that wraps around any number of child content pages.
Similarly, UserControls allow you to re-use whatever content you want on whatever page you want, whether it's a MasterPage or ContentPage:
<%# Page Language="C#" %>
<%# Register TagPrefix="uc" TagName="Spinner"
Src="~/Controls/Spinner.ascx" %>
<html>
<body>
<form runat="server">
<uc:Spinner id="Spinner1"
runat="server"
MinValue="1"
MaxValue="10" />
</form>
</body>
Methods (C#)
Executable code:
Page include
<!--#include file="a.aspx"-->
Execute independently inside a page
<% Server.Execute("a.aspx"); %>
Non-executable code:
<% Response.WriteFile("a.inc"); %>
I believe this is what you are looking for.
<!--#include file="wisdom.aspx"-->
I use C#.net
<% Response.WriteFile("YourPage.aspx"); %>
and this works real well for me!!
I also use your line,
<!--#include file="wisdom.aspx"-->
when I am in HTML mode.

Changing ScriptManager's attribute globally

In each projects we have several pages which have the following tag
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
Now we would like to change those to (about 80% of Pages)
<asp:ScriptManager ID="ScriptManager1" EnableScriptGlobalization="true" EnableScriptLocalization="true" runat="server">
</asp:ScriptManager>
Is there any way to do that from a single source like Web.config or Global.asax or using any HTTPHandler.
If you have a BasePage or a Master page then you could find the controls before the render event and modify it's properties
You could simply use a search-and-replace regex to do this job. :)
I have made an user control and placed the ajax calendar code in that. After that I replaced the Ajax calendar in the page with the user control.
Now for changing globally I can change it from the single user control.
