This must be done manually, so add the node to the treeView with Node.Add and then, store this node into a variable that we will provide as argument for the helper method AddNode: try In our logic, we will add this node as well and it will contain basically all the nodes of the file. On the previous XML file, the document name is urlset, and so on with other xml files. Now, as you know, on every XML file there's a document name that defines what's the file about, for example: As next, create a new structure of a XmlDocument with the string XML data that you have using the LoadXml method from the created instance.Īs we assume that you may have already some data in the treeView, we will clear all nodes previous to the render process using the Nodes.Clear method of the TreeView. As first step, you need to create a variable that contains the XML string, this can be obtained either from a local or remote source, so it's basically up to you how to retrieve the data from the XML file that you want to render. In this example, we will have a treeView1 variable that represents a TreeView component added to the form by Drag & Drop from the toolbox. In this article, we'll show you how to render an entire XML document into a TreeView of your Winforms application with C#. Looking for a way to render an entire XML document into a expandable TreeView of Winforms? You surely don't want to loop over every node and write a lot of "if's" according to the type and data that the node contains, don't you? Instead, we want to share with you an interesting approach of how to render automatically any XML file structure into a TreeView component of Winforms that will make your life easier.
