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
