  • Most performant ASP.NET web controls suite

    - by DotNetter
    Personally I've been working for years with Telerik's RadControls and DevExpress ASP.NET controls. IMHO they both produce quite a lot HTML overhead on the client side thus for that I've never been highly pleased with them. I also know about Infragistics, ComponentOne, ComponentArt, etc. How are these? I'd assume they are not much different than those I mentioned. Which (commercial) controls suite generates the most compact HTML on the client side? Do you have any recommendations?

  • are there any negative implications of sourcing a javascript file that does not actually exist?

    - by dreftymac
    If you do script src="/path/to/nonexistent/file.js" in an HTML file and call that in a browser, and there are no dependencies or resources anywhere else in the HTML file that expect the file or code therein to actually exist, is there anything inherently bad-practice about doing this? Yes, it is an odd question. The rationale is the developer is dealing with a CMS that allows custom (self-contained) javascript files to be provided in certain circumstances. The problem is the CMS is not very flexible when it comes to creating conditional includes for javascript. Therefore it is easier to just make references to the self-contained js files regardless of whether they are actually at the specified path. Since no errors are displayed to the user, should this practice be considered a viable option?

  • Empty page instead of custom tomcat error page

    - by Alexander
    My setting: Apache 2.2 + Tomcat 6.0 @ Windows 2008 R2 64bit static webpages: / servlet: /foo tomcat and apache are connected by mod_jk 404.jsp is placed in tomcat\webapps\ROOT tomcat\conf\web.xml: <error-page> <error-code>404</error-code> <location>/404.jsp</location> </error-page> apache\conf\extra\httpd-ssl.conf: JkMount /foo/* worker1 JkMount /404.jsp worker1 When I open https://...../404.jsp my custom error page is displayed. But when I open https://...../foo/nonexisting.html an empty page is displayed. If I remove the <error-page>...</error-page> code from web.xml and open https://...../foo/nonexisting.html then tomcats own 404 is displayed. Any hints?

  • Injecting jQuery into a page fails when using Google AJAX Libraries API

    - by jakemcgraw
    I'd like to inject jQuery into a page using the Google AJAX Libraries API, I've come up with the following solution: http://my-domain.com/inject-jquery.js: ;((function(){ // Call this function once jQuery is available var func = function() { jQuery("body").prepend('<div>jQuery Rocks!</div>'); }; // Detect if page is already using jQuery if (!window.jQuery) { var done = false; var head = document.getElementsByTagName('head')[0]; var script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.onload = script.onreadystatechange = function(){ // Once Google AJAX Libraries API is loaded ... if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) { done = true; // ... load jQuery ... window.google.load("jquery", "1", {callback:function(){ jQuery.noConflict(); // ... jQuery available, fire function. func(); }}); // Prevent IE memory leaking script.onload = script.onreadystatechange = null; head.removeChild(script); } } // Load Google AJAX Libraries API head.appendChild(script); // Page already using jQuery, fire function } else { func(); } })()); The script would then be included in a page on a separate domain: http://some-other-domain.com/page.html: <html> <head> <title>This is my page</title> </head> <body> <h1>This is my page.</h1> <script src="http://my-domain.com/inject-jquery.js"></script> </body> </html> In Firefox 3 I get the following error: Module: 'jquery' must be loaded before DOM onLoad! jsapi (line 16) The error appears to be specific to the Google AJAX Libraries API, as I've seen others use a jQuery bookmarklet to inject jQuery into the current page. My question: Is there a method for injecting the Google AJAX Libraries API / jQuery into a page regardless of the onload/onready state?

  • How to save some values from an array in a controller in Rails?

    - by Alfred Nerstu
    I've got a links array that I'm saving to a database. The problem is that the records aren't saved in the order of the array ie links[1] is saved before links[2] and so on... This is a example from the view file: <p> <label for="links_9_label">Label</label> <input id="links_9_name" name="links[9][name]" size="30" type="text" /> <input id="links_9_url" name="links[9][url]" size="30" type="text" /> </p> And this is my controller: def create @links = params[:links].values.collect { |link| @user.links.new(link) } respond_to do |format| if @links.all?(&:valid?) @links.each(&:save!) flash[:notice] = 'Links were successfully created.' format.html { redirect_to(links_url) } else format.html { render :action => "new" } end end end Thanks in advance!

  • Check on every page to ensure user has validated as being over 18

    - by liquilife
    Hi Guys and Girls. I'm working on a website (tobacco related) that requires all visitors to validate they are over 18 before they can view the site. I have a form in place that validates the age but I'm at a dead end. How can I use this to store a cookie that they've passed the test and do a check on all pages to see if this check has already been passed or not? Any suggestions and help would be hugely appreciated!

  • how to run javascript from c# code ?

    - by dotnetcoder
    I have a webrequest that returns a html response which has form inside with hidden fields with some javascript that submits the form automatically on pageload ( if this was run in a browser). If I save this file as *.html and run this file in browser , the java script code automatically posts the form and the output is excel file. I want to be able to generate this file from a c# code which is not running in broswer. I tried mocking thr form post but its complicated and has various scenarios based on the original webrequest querystring. any pointers.... i know its not possible to probably run JS code that posts the form - from within c# code but still thought of chekcing if someone has done that.

  • poblems with jquery code

    Another jquery issue... I have tried this several times using "class" and "id" elements and I can not get it right. I am hoping the brains on stackoverflow can help!

  • adding visual effects to RJS before action rendered

    - by Sam
    I just started using RJS which is awesome however I am used to putting visual effects in the link_to_remote and such and I'm not sure how to trigger actions before and after remotes are triggered. Take this link for example: HTML <span id="<%= "edit_comment_link_#{comment.id.to_s}"%>" style="float:left;"> <%= link_to_remote "edit", {:update => "comment_#{comment.id.to_s}", :url => edit_post_comment_path(comment.post, comment), :method => :get}%> | </span> Controller: def edit @comment = Comment.find(params[:id]) respond_to do |format| #format.html render edit_comment_path(@comment) format.js end end RJS: page.replace_html "edit_comment_link_#{@comment.id.to_s}", "currently editing | " So is RJS mainly for after actions are rendered visual effects such as a spinner should be put into the link_to_remote with call_backs? Is this a good way of doing things?

  • Not able to override CSS within IFrame

    - by Madhur Ahuja
    I am using disqus comments for my jekyll blog with some CSS styles overriden in my stylesheet and used to work perfectly. Recently, disqus has introduced a new UI for their comments system which has completely broken the font colors. Since my site has dark background, I am trying to apply styles based on new disqus HTML structure generated. However, it seems that none of my styles get applied. It seems that is because disqus is loaded within iframe. Any ideas how can I fix the font colors. Example of the post: http://www.madhur.co.in/blog/2012/03/27/codeplexmovegit.html UPDATE Based on this question How to apply CSS to iFrame? it seems that you cannot style a child IFrame cross domain. I am wondering how it used to work earlier. Disqus even has documentation on it http://docs.disqus.com/help/69/

  • Show different sub-sets of a view model's properties in an edit view

    - by Martin R-L
    In the context of C# 4, ASP.NET MVC 2, and NHibernate; I've got the following scenario: Let's assume an entity Product that have an association to ProductType. In a product edit view; how do I implement that only a sub-set of the product's properties are shown based on the ProductType association in an elegant and DRY way? I.e., different properties shall be shown for different values of a property of the ProductType. Use a product view model builder, and from different view models automagically generate the view with my own Html.EditorForModel() (including drop-downs and other stuff not out-of-the-box)? Attribute the properties of one view model and use the Html.EditorForModel() way aforementioned? Use one model, but implement different web controls (view strategies) (can it be done DRY?)? Something else entirely?

  • CSS Rollovers: how to maintain "hit area" size when hidden image is larger than anchor area

    - by nukefusion
    I have a small problem and I don't think what I want to do can be achieved with just pure CSS, but I figured I'd ask anyway. Basically, I have one DIV which contains a hyperlinked element that is smaller in size to it's parent DIV. So in effect I have a square within a square with the inner square being the "hit area". When I mouse over this inner square I want the background of the outer square to change. I know it's not possible to change the parent DIV's background on a:hover, but I figured I could give the illusion of it happening by nesting a hidden image inside the anchor. This works great until I want to "roll off". The problem is that I want the image to disappear when I leave the area of the anchor tag, not the larger hidden image. Is this possible? For the benefit of everyone I've provided an example to demonstrate what I mean: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Test Rollover</title> <link href="main.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="d1"> <a href="#nogo"> <b id="b1"></b> <b id="b2"></b> </a> </div> </body> And the css: #b1 { width: 200px; height: 200px; top: 100px; left: 100px; background-color:aqua; position: absolute; z-index: 100; } #b2 { width: 400px; height: 400px; background-color:lime; position: absolute; display: none; z-index: 90; } #d1 { width: 400px; height: 400px; background-color:fuchsia; position: relative; } #d1 a:hover #b2 { display: block; } In this example I want the green outer square to disappear when I leave the bounds of the hidden inner blue square.

  • Store web content in XML using wiki markup

    - by Mike
    Does anyone have an XML style sheet that'll convert wiki-like markup to HTML? Or is that a bad idea? I only found one style sheet that'll convert HTML to wiki-like markup, view-source:http://mozile.mozdev.org/0.8/demos/html2wiki.xsl . Or is this a bad idea? Basically, instead of following strict rules with my XML tags to format my content, I thought it'd be best to have something like this: <content> \## This is my heading </content> That way I'm free to display my content however I feel without having to modify my style sheet. Any ideas?

  • Include at text file as is in (Python) Sphinx Docs

    - by Gregg Lind
    (using Python-Sphinx Documentation tool) I have a .txt log file I'd like to build into _build/html unaltered. What do I need to alter in conf.py, index.rst, etc. Here is the layout: src/ index.rst some_doc.rst somefile.txt How do I get somefile.txt into the html build? I tried adding a line like this to index.rst: Contents: .. toctree:: :maxdepth: 2 some_doc "somefile.txt" hoping it would work by magic, but no magic here! Assuming this is even possible, what would I put in some_doc.rst to refer/link to that file? Note Yes, I'm aware I could put it in /static and just be done with it, but that seems like a total hack, and ugly.

  • How are java.lang.Object's protected methods protected from subclasses?

    - by Adrian Lang
    The keyword protected grants access to classes in the same package and subclasses (http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html). Now, every class has java.lang.Object as superclass (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html). Hence I conclude that every class may access java.lang.Object's methods even if they are protected. Take a look at the following example: public class Testclass { public Object getOne() throws CloneNotSupportedException { return this.clone(); } public Object getTwo() throws CloneNotSupportedException { return ((Object) this).clone(); } } While getOne() compiles fine, getTwo() gives Testclass.java:6: clone() has protected access in java.lang.Object return ((Object) this).clone(); I neither understand why getTwo() doesn't compile nor what's the difference (regarding the access of java.lang.Objects members) with getOne().

  • Linq to Sql, Repositories, and Asp.Net MVC ViewData: How to remove redundancy?

    - by Dr. Zim
    Linq to SQL creates objects which are IQueryable and full of relations. Html Helpers require specific interface objects like IEnumerable<SelectListItem>. What I think could happen: Reuse the objects from Linq to SQL without all the baggage, i.e., return Pocos from the Linq to SQL objects without additional Domain Model classes? Extract objects that easily convert to (or are) Html helper objects like the SelectListItem enumeration? Is there any way to do this without breaking separation of concerns? Some neat oop trick to bridge the needs? For example, if this were within a repository, the SelectListItem wouldn't be there. The select new is a nice way to cut out an object from the Linq to SQL without the baggage but it's still referencing a class that shouldn't be referenced: IEnumerable<SelectListItem> result = (from record in db.table select new SelectListItem { Selected = record.selected, Text= record.Text, Value= record.Value } ).AsEnumerable();

  • Casting a primitive int to a Number

    - by Tamer
    Let's say that I have the following: int a = 2; Number b = (Number) a; System.out.println(b); // Prints 2 http://java.sun.com/docs/books/jls/first_edition/html/15.doc.html#238146 says that a primitive value may not be cast to a reference type. Does Java know to create an Integer from the primitive int and then cast to the superclass? How exactly does Java handle this behind the scenes? Thanks!
