Umbraco 10, Umbraco 9, Umbraco 8, Umbraco 7, Umbraco 4 - Code Snippets

1) Create a Media Picker in your Document Type: "listFilesFromAParticularFolder"  2) Create this Macro @using Examine @using Examine.SearchCriteria @using UmbracoExamine @using System.Xml.XPath @{                  if (@Model.listFilesFromAParticularFolder != "" && @Model.listFilesFromAParticularFolder != null)  {                    dynamic imageFolder = Library.NodeById(@Model.listFilesFromAParticularFolder);                                       <h2>Related Documents</h2>                       ...

var getNodes = Model.AncestorOrSelf().Descendants("ShopItem"); // Programmes Nodes int numberOfNodes = getNodes.Count(); @numberOfNodes

The purpose of this is to allow the user to influence the colours of a page by loading a different style-sheet. Using CSS, Umbraco and Razor. STEP 1: Create a New Data Type 1)  Add a new Data Type called "Colours" 2) Make the Data Type a Checkbox List and add some Values to it for the User. Example: STEP 2: Add the Colours Option to the Document Type in the Backend STEP 3: Add Seperate CSS Style Sheets with your CSS Rules For example:  colour-purple.css, colour-gree.css, color-orange.css, colour-pink.css  STEP 4: Create Some Razor Code ... @if (@Model.pageColour == "Purple") { @Html.Raw("<link href=\"/css/colour-purple.css\" rel=\"stylesheet\" type=\"text/css\" media=\"all\" />"); } @if (@Model.pageColour == "Pink") { @Html.Raw("<link href=\"/css/colour-pink.css\" rel=\"stylesheet\" type=\"text/css\" media=\"all\...

@Html.Raw("Hello: " + @Model.NodeById(listingPage).Children.Where("template=1201").Count());

if(@node.Url == @Model.Url) { <li> <a href="@node.Url"><span style="text-decoration:underline">@node.Name</span></a>                                       </li> } else { <li> <a href="@node.Url">@node.Name</a>                                       </li> }

@if (@Model.address != "") { var output = (umbraco.library.ReplaceLineBreaks(@Model.address)); <p>@Html.Raw(@output)</p> }

The issue below can be resolved by: 1) Rename the Folders: App_Browser and App_Data to something like, App_Browser_old and App_Data_old 2) Log in to your Umbraco Backend If you receive errors like:  "Values cannot be returned until Resolution is frozen" , Press the refresh button. If you then get the message: The website is restarting Please wait for 10s while we prepare to serve the page you have requested... Go for a cup of tea and come back. Umbraco 4 Backend Still not working?  In IIS --> Application Pools --> Change the Managed Pipeline to Classic instead of Integrated for the site

To reset the admin password of a Umbraco website. 1. In Sql server, run the following script on the database: USE  INSERT-YOUR-DATABASE-NAME-HERE GO UPDATE umbracoUser set userdisabled=0, userLogin='admin', userPassword='default' where id=0 2. In your web config file, find the "UsersMemnershipProvider" section, change the setting: passwordFormat="Hashed" to passwordFormat="Clear" You should now be able to login using the Username: Admin and the Password: default ("the two sweetest words in the english language").

The Following Razor code for Umbraco displays Next and Previous Buttons / Links and a Return to the Parent node Button / Link: Example 1: <umbraco:Macro runat="server" language="cshtml">    @{         if (@Model.Previous() != null) {             <a href="@Model.Previous().Url">Previous Image</a> } var currentPg = Model; <a href="@currentPg.Parent.Url">View all @currentPg.Parent.Name</a> if (@Model.Next() != null) {             <a href="@Model.Next().Url">Next Image</a>         }     } </umbraco:Macro> Example 2: This Example shows you how to ignore pages that are hidden from the navigation in Umbraco.    @{ if (@Model.Previous() != null) { var node = Model.Previous(); if (node.Visible) {             <a class="button green"...

Umbraco Inline Razor to refer to a Stylesheet Example:  <umbraco:Macro runat="server" language="cshtml"> @{var myStyleSheet = "~/css/styles.css";} <link rel="stylesheet"  href="@Href(myStyleSheet)" type="text/css" media="screen" /> @{var IEStyleSheet = "~/css/stylesIE.css";} <!--[if lte IE 8]> <link rel="stylesheet" href="@Href(myStyleSheet)" type="text/css" media="screen" /> <![endif]--> </umbraco:Macro> Umbraco Inline Razor to refer to lots of Stylesheets, using the folder as the reference Example <umbraco:Macro runat="server" language="cshtml"> @{var myStyleSheetFolder = "~/css/";} <link href=" @Href(myStyleSheetFolder) bootstrap.css" rel="stylesheet">       <link rel="stylesheet" type="text/css" href="...

<script> function validateForm() { var x=document.forms["myForm"]["name"].value; var x=document.forms["myForm"]["email"].value; if (x==null || x=="" || y==null || y=="")   {  document.getElementById('myDiv').innerHTML = '<span style="font-weight:bold;color:#800000">***Please fill in all requred fileds.</span>';   return false;   } } </script> <div id="myDiv"> </div> <div id="comments"> <form action="thank-you.aspx" method="post" name="myForm" onsubmit="return validateForm()">           <p>             <input type="text" name="name" id="name" value="" size="22">             <label for="name"><small>Name (required)</small></label>           </p>           <p>   ...

The Highlighted lines below shows you how to write out a Substring from Razor in Umbraco. 1)  @Html.Raw(@item.HomePageIntro.ToString().Substring(0, 290)) or 2)   @item.HomePageIntro.ToString().Substring(0, 290) (Example 1 will write out the HTML characters, Example 2 removes Encoding.) Example of writing out a SubString in Umbraco using Razor @inherits umbraco.MacroEngines.DynamicNodeContext @{ var numberOfItems = 6; }     @foreach (var item in @Model.Children.Where("Visible").Take(numberOfItems))     {<article>         <figure><img src="images/triangle.jpg" alt=""></figure>         <strong>@item.PageHeading </strong>         <p> @Html.Raw(@item.HomePageIntro.ToString().Substring(0, 290)) ...</p> <p class="more"><a href="@item.Url">FIND OUT MORE</a></p>       </article>}

The following code highlights the string replacement function in umbraco: The example below places a space after each comma (basically to help with the formatting) from values selected from a multiple drop down list ("placementHospital"). The important bit is highlighted. <?xml  version="1.0" encoding="UTF-8"?> <! DOCTYPE xsl:stylesheet [  <! ENTITY nbsp " &#x00A0; "> ]> < xsl:stylesheet     version = "1.0"     xmlns:xsl = "http://www.w3.org/1999/XSL/Transform"     xmlns:msxml = "urn:schemas-microsoft-com:xslt"    xmlns:umbraco.library = "urn:umbraco.library"  xmlns:Exslt.ExsltCommon = "urn:Exslt.ExsltCommon"  xmlns:Exslt.ExsltDatesAndTimes = "urn:Exslt.ExsltDatesAndTimes"  xmlns:Exslt.ExsltMath = "urn:Exslt.ExsltMath"  xmlns:Exslt.ExsltRegularExpressions = "urn:Exslt.ExsltRegularExpressions"  xmlns:Exslt.ExsltStrings = "urn:E...
