html-helper

问题 Just wondering what the difference is between these two and what the benefit for one or the other of them would be when I build my table in my HtmlHelper HtmlTable table = new HtmlTable(); and: TagBuilder table = new TagBuilder("table"); This is more or less the same as this question, Why use TagBuilder instead of StringBuilder? but I'm wondering more specifically about the difference between these two . 回答1: The main difference is that HtmlTable provides typed and correctly named properties

问题 You can provide alternate templates for individual types, but is it possible to override the template that wraps the label, field and validation up. Change: <div class="editor-label"><label for="Content">Content</label></div> <div class="editor-field"><input class="text-box single-line" id="Content" name="Content" type="text" value="" /> </div> To: <div class="field"> <label for="Content">Content</label> <input class="text-box single-line" id="Content" name="Content" type="text" value="" /> <

问题 I have a razor helper method that needs to take in a Func<> that will return some HTML content to print out. This is what I originally had: @helper node(string title, Func<HelperResult> descriptions) { .... <div>@descriptions()</div> .... } @node("title", new Func<HelperResult>(() => { return new HelperResult( @<text> <span>"desc1"</span> <span>"desc2"</span> </text>); })) Unfortunately with this my text never gets printed out. No error either. So I learned about inline helpers, and changed

问题 I have the following controller auto-generated by asp.net // // POST: /Account/LogOff [HttpPost] [ValidateAntiForgeryToken] public ActionResult LogOff() { AuthenticationManager.SignOut(); return RedirectToAction("Index", "Home"); } Now I have a log off button.

问题 Here is a scenario: Let's say I have site with two controllers responsible for displaying different type of content - Pages and Articles. I need to embed Partial View into my masterpage that will list pages and articles filtered with some criteria, and be displayed on each page. I cannot set Model on my masterpage (am I right?).

It was fun, but I'm wondering what benefit I've gained from this exercise, if any? <?php $output = implode("\n", array( $html->docType(), $html->tag('html', implode("\n", array( $html->tag('head', implode("\n", array( $html->charset(), $html->tag('title', 'Title For App'), $html->css('css', NULL, array('media' => 'screen

问题 I'm not even sure if this is possible, but I thought I would check to see if there is any way to make this easier. First, I have some repeated markup in my site that looks like this: <div class="module"> <h3>Title</h3> <div> <p>Information goes here</p> </div> </div> What I want to do is wrap this up in some kind of helper/section so that I could do something like this @MyHelper("This is my Title") { <p>Here is my custom markup</p> } Then, when it renders, it would inject the title passed in
