what is the meaning of this? - asp.net

I know that this will sound stupid to some of you, but when an ASPX page has something like this:
<%# Page Title="[$TITLES_listevents{uneditable}]" Language="C#" MasterPageFile="~/sitebase/templates/page.master" AutoEventWireup="true" CodeBehind="list.aspx.cs" Inherits="list" %>`
or something like:
<div id="panelGroupEventPackageOnlyDescription" runat="server" visible="<%# ShowGroupEventPackageOnly %>">
[$ITEMLIST_groupeventpackageonly]
</div>
what does it mean?
Regards

I'm assuming that your query is for the bits that look like this: Title="[$TITLES_listevents{uneditable}]"
It doesn't look like asp.net to me. It could be that the page was generated by a templating tool that left some rubbish behind, is it in source control, can you ask whoever created the page?

Hey All,
apparently it means that It will use site text to set the title, this is done when there is an xml file that produces site data and you need some of those data to be published dynamically to you front end website. this is the results of custom controls being used on things like label, dropdownbox etc...
this is one of the legacy piece of software where the one who wrote the code is gone AWOL with little doc, only happens when you are emerging from recession lol.....

Composite C1 - User Control not showing on page

I have a website created with Composite C1, and I'm attempting to display a user control on a page using the Composite.AspNet.LoadUserControl function. Just following the example on the website with a very simple user control that simply outputs hello world in a heading 1 element doesn't seem to show anything. You can see the page here:
http://wallbro.plazacommerce.com/Contact
Where the user control is supposed to be rendered within the HTML, all I see is:
<c1marker:marker xmlns:c1marker="http://www.composite.net/ns/asp.net/controls" key="[Composite.Function.Render.Asp.Net.Control.0]" />
The user control consists of:
<%# Control Language="C#" AutoEventWireup="true" CodeFile="Test.ascx.cs" Inherits="Frontend_Controls_Test" %>
<h1>Hello</h1>
Is there anything else that I need to do? I can't find any other help on this issue, and it seems so simple that it must be something obvious that I'm doing wrong.
Paul, sorry if i intrepreted wrongly.
I have searched for c1marker for but i didnt find anything.
Do u mean insertng user control created in front end as i noticed "Frontend_Controls_Test"
<f:function xmlns:f="http://www.composite.net/ns/function/1.0"
name="Composite.AspNet.LoadUserControl">
<f:param name="Path" value="~/frontend/Test.ascx" /> </f:function>
name="Path" value="~/frontend/Test.ascx"
Here relative path with respect to frontend can be given.
if my interpretation is totally wrong please forgive.Also please tell me where is this c1marker:marker
Is it there in composite solution...or is it some customization made

How to fetch Title of news Article in GoogleNewsSitemap using kentico CMS

I am using Kentico 5.5R2 for my website, where i want to generate GoogleNewsSitemap. So far my code is able to fetch newarticle url and publication date, but i'm not able to fetch the title of news article dynamically
here's code
<url>
<loc><%# GetAbsoluteUrl(GetDocumentUrl()) %></loc>
<news:news>
<news:publication>
<news:name>Yourwellness </news:name>
<news:language>eng</news:language>
</news:publication>
<news:genres>PressRelease, Blog</news:genres>
<news:publication_date>
<%# GetDateTime("DocumentModifiedWhen", "dd-MMM-yy")%>
</news:publication_date>
<news:title>method for fetching title Comes here </news:title>
<news:keywords>Health</news:keywords>
</news:news>
</url>
I tried many methods to fetch title but it comes as blank.
<%# Eval("DocumentName") %> is the default for the node unless you are using something else with a custom Document Type
Have you tried just a regular Eval? Can't remember the field name, and not at my work computer, but probably one of these:
<%#Eval("DocumentTitle") %>
<%#Eval("Title") %>
You might be looking for:
<%# Eval("DocumentName") %>
It depends on what the individual Document Type is using for the title. It could be the document name as above, or something like "NewTitle".
Where are you using that code and what web part are you using?
Have you tried to get the title in the code behind?

Import HTML page in .NET

The following code imports an HTML page (which simply holds one table) into my .ASP page. This works great, but I now am converting into .NET and am having obstacles.
<% Response.Write(getFilesContent("table.htm")) %>
This code does not work in .NET, and I read that this method is not recommended or widely used? Are there any thoughts, advice, or solutions about this?
I simply want to import this HTML page to read in a content box within my .NET page. In essence, the .NET page is hosting the HTML table.
Any help would be greatly appreciated.
Thank you in advance for your time and help.
To get you started, take a look at the System.Net.WebClient class http://msdn.microsoft.com/en-us/library/system.net.webclient%28v=vs.80%29.aspx
In particular, the "DownloadXXX" methods.
You could put the table in an asp.net user control
A asp.net custom user control can act like an include that encapsulates asp.net
markup.
here is a tutorial:
http://ondotnet.com/pub/a/dotnet/excerpt/progaspdotnet_14/index1.html
After you create the control add a reference
<%#Register tagprefix="uc" Tagname="html" src="custom_html.ascx" %>
then just a the control markup (in this case <uc:html runat="server"/>)
It would be cool the create a control the reads an html file by adding a src property
Try this:
<% Response.Write(New StreamReader(Server.MapPath("~/table.htm")).ReadToEnd()) %>

asp.net - Use ascx as a layout template

This is my layout template (ascx without code behind)
<%# Control Language="C#" AutoEventWireup="true" Inherits="ws.helpers.LayoutUC" %>
<div>blah blah blah</div>
<ws:Panel runat="server" ID="left"></ws:Panel>
<ws:Panel runat="server" ID="main"></ws:Panel>
<ws:Panel runat="server" ID="right"></ws:Panel>
Modules will be added into ws:Panel later.
I also allow my user create their own ascx file to custom their page layout. And because of this i do a string replace all dangerous part like script tag (runat="server"), all asp.net html tag, <%, <%#, <#.... from their custom.
Im not worry about XSS, so dont comment on it, and ask why?
I want know your thinking about this. Is is safe? Is it scalable? Is it standard or a bad way?
Have a look at the INaminingContainer Interface http://msdn.microsoft.com/en-us/library/system.web.ui.inamingcontainer.aspx.
<asp:YourControl>
<LeftColumn>
<asp:Literal ID="literal1" runat="server" Text="User created literal" />
</LeftColumn>
</asp:YourControl>
In the .ascx from the users, they register your control and insert asp.net code into properties. In the 'YourControl' class you create placeholders and insert the markup set to a specific property into these placeholders. (e.g. everything between <LeftColumn> and </LeftColumn> will the inserted into
<asp:Placeholder ID="PlaceholderLeftColumn" runat="server"/>
Edit: I summed some of the TemplateContainer issue up and posted it here: http://www.tomot.de/en-us/article/2/asp.net/how-to-create-an-asp.net-control-that-behaves-as-a-template-container-to-nest-content-via-markup
You are allowing user-uploaded content; this is inherently unsafe and there are whole books dedicated to best practices. Given that you are doing it anyway, as long as you make sure you scrub the input, is it scalable? You are allowing creation of user-uploaded files on your site. How many will there be? How many users? What about load-balancing? This solution will not scale for many users, files, or servers.
It sounds like you are trying to create a simple CMS. Why not use one that exists currently, or adopt parts of an open source solution?

Simple HTML construction in ASP.NET?

A simple question, I think:
I want to put a tag into an ASP.NET app I've been asked to maintain, so I'm coming at this from a newbie point of view just tinkering around the edges without knowing a lot.
I wrote an old ASP application back in 1998, so I am just running on memory...
How do I write some output to the webpage?
I know I can use an
<asp:label id="blah">
but then I need to define a Label blah; in my code behind and then assign it.
I believe that I can put in-place:
<% Response.Write("sometext"); %>
and that will write sometext in the location within the page. (Am I correct?)
Lastly, I remember there was a syntax to the effect of
<%= "some string" %>
but I can't find the documentation on it, to say either it is deprecated, unadvised, or the rationale for such a decision.
I have tried googling for "ASP.NET grammar" but I can't even find a good description that "<%=" even exists, though it is mentioned in a few blogs.
For something simple, like inject the global version number, or the current date, then I can't see anything particularly wrong with in-place composition - it would save me defining 15 labels and having to initialise them all - though perhaps the asp:label approach could reference one global instance of a label?
Just asking for opinions on good practices :)
<%= string %> is perfectly valid ASP.NET syntax. The reason you will often find references to problems with using that is people use <%= (equivalent to Response.Write) when they should use <%# (for databinding) or vice-versa.
For example, we use it very extensively in our content managed site, where we pull in values from a global settings repository:
<%= SiteContext.Current.GetSetting("SiteTitle") %>
MSDN:
MSDN entry on <%= (this is under the JScript.NET section but still applies)
MSDN entry on <%#
Some others suggest <%= is not a "best practice" or a very good approach, but I strongly disagree with that sentiment. For an MVC-ish type site (especially a site that is template- or view-driven in some way), the most direct approach is frequently more effective than using server controls.
Just be mindful that when you use an <asp:Label /> it renders the .Text inside the <span> tag whereas an <asp:Literal /> adds no extraneous HTML to the string passed to it.
For example, if you were building a content management system and wanted to display user-driven HTML, a Label control would not correctly display the output from a WYSIWYG type rich textbox whereas a Literal control is the appropriate choice.
The <%= %> is the late-bound equivalent of the Literal's .Text property. The only difference here is when the value is placed in the page (aside from obvious syntax and separation of concerns paradigm) during the course of the page lifecycle.
Since the .Text property is on a control inherited from WebControl, it can be set/read/manipulated during any of the events following the control's Load event (wherever/whenever you load the control inside the page), but the <%= %> text cannot be directly read/used/manipulated by the code-behind without referencing some other control to get to it (like a containing div's InnerHtml property).
There are lots of options. You could use a single label, and string concatenate all the data you want displayed in that location.
You could create a user control with the layout you want and assign values that way.
You could inject it directly with response.write or the <%= %> syntax
You could create an HtmlGenericControl in your code behind (it's a div), add some text to it, and inject it into the pages controls collection.
Whatever you pick, try and go with the existing style of the coded page.
Look up the term "render blocks" for the <% %> syntax.
How about using
<asp:Literal id="z" text="goofy" runat="server" />?
Labels are usually used with forms.
You can also take full control of the rendering of your pages and controls and compose whatever you need to. You control the HTML, the order of rendering your controls, etc...
Go with the <asp:label /> (or a literal control if you want to customize some html in the content). Seriously. I'ts not that hard: when you put label in your markup visual studio will create it in the code-behind for you, so there's no extra work involved.
You could use the <%= "some string" %> syntax in web forms, but there can be issues when mixing that with the asp controls and there's a good reason new frameworks moved away from mixing logic like that in with your markup.
