You can control the selection state of the RadzenTree component via its Value property. Propagate the Template to the childrenĪ = FileOrFolderTemplate Set some margin if the current data item is a file (!isDirectory)īuilder.AddAttribute(2, "Style", "margin-left: 24px") Ī = Directory.EnumerateFileSystemEntries(directory) Ī = (path) => Directory.Exists((string)path) RenderFragment FileOrFolderTemplate = (context) => builder =>īool isDirectory = Directory.Exists(path) īuilder.AddAttribute(1, "Icon", isDirectory ? "folder" : "insert_drive_file") Here is an example:Įntries = Directory.GetDirectories(HostEnvironment.ContentRootPath) The most straight forward way to define a RadzenTree is to specify its items. The sample application used for this tutorial is available in the Radzen Github repository. Now when you run the example the tree will load the products on demand - when the user expands a category node. What property to use for their text and that they don’t have children of their own. Those two configure the child nodes - specify Set a property with Name categories and Value $ = (product) => false. Handle the Load event of the page and invoke the getCategories data source method.Tree node will display the products from that category. To add text to a shape, select the shape, and then type. From the Blocks and Blocks Raised stencils, drag block shapes onto the drawing page to represent stages in a tree structure. We will create a Tree component that displays the items from the Northwind Categories table. Click File > New > Templates > General, and then open Block Diagram. Make a free decision tree diagram See why millions of users across the globe choose Lucidchart. See and build the future from anywhere with Lucidchart. Customize shapes, import data, and so much more. Using in Radzen Displaying Categories and Products Lucidchart is an intelligent diagramming application that takes decision tree diagrams to the next level.
