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?

I am working on an old Web Forms application with a lot of <%= %> bee sting code nuggets. I would like ReSharper to flag these and suggest replacement with the encoded version <%: %> (see here).
I have tried to create a custom pattern via this article, however I am not sure what to use as the placeholder between the opening and closing tags. The only placeholder types that seem available for ASPX pages are tag name, attribute, attribute value, and content placeholder. None of these seem to select (find) the value in the bee sting code nugget.
Since I only really need to find/replace the opening tag, I tried just using <%= as the pattern (eliminating the need for a placeholder), however ReSharper does not let me save it. It requires the closing tag to be in the pattern to save.
How can I configure ReSharper to suggest replacing <%= %> with <%: %>?
I am a asp .net beginner. I want to use some objects created at Site.Master.cs in Site.Master. Is there an easy way to do it?
I know how to do it in MVC(by using view(the object)). But how can i do it in normal ASP .net web application?
I don't understand what exactly you want to do.
If you want to insert some string into tag's title you can insert the following thing in SiteMaster.master file:
<img src="<%= Page.ResolveUrl("~/") %>images/logo.png">
instead of:
<img src="images/logo.png">
In the first case there will be calculated the path from the root of your application. In the second case there will be relative link. This is because server will CALCULATE the value of Page.ResolveUrl("~") function and will WRITE it in src tag.
You can do the same thing with any other methods, classes if you defined them properly. But I wouldn't recommend you to implement complicated logic in .aspx files (or .master files). Because you can end up with many difficulties with testing and styling such application.
There are other server tags:
<% %> - an embedded code block is server code that executes during the page's render phase. The code in the block can execute programming statements and call functions in the current page class. Description and examples
<%= %> - most useful for displaying single pieces of information. Description and examples
<%# %> - data binding expression syntax. Description and examples
<%$ %> - ASP.NET Expression. Description and examples
<%# %> - Directive Syntax. Description and examples
<%-- --%> - Server-Side Comments. Description and examples
<%: %> like <%= %> - But HtmlEncodes the output (new with Asp.Net 4). Description and examples
Another way: you can use JSON to send some data to the client and then process it with javascript. Take a look at this project.
If the #Page directive in your .aspx file has Inherits="XYZ" where XYZ is the class declared in your .cs file, you can simply add a protected field to your class and assign a value to it. You'll be able to access it in the .aspx file just by using its name.
You can also use HttpContext.Items property to keep objects during a single request:
HttpContext.Current.Items["SavedItem"] = "hello world";
And use it in page:
<%= ((string)Context.Items["SavedItem"]) %>
Any public or protected property or method in Site.Master.cs will be accessible from Site.Master.
but how to invoke c# code in aspx ?
There are several ways, including the <%= %> construction, and databinding syntax.
It would help if you explained what you're trying to achieve.
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()) %>
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.....
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.
