How to create a TreevView from XML
In the previous example, we learned how to read an XML file node by node. Now, we will take it a step further and demonstrate how to read the XML file and populate a TreeView control with the data.
To achieve this, we will use the XmlReader class to read the XML file. The XmlReader provides a forward-only, read-only access to XML data, making it efficient for parsing large XML files. We will traverse through the XML file and extract the necessary data from each node.
Once we have obtained the data from the XML file, we can populate a TreeView control. The TreeView control is a hierarchical control that allows us to display data in a tree-like structure. Each node in the TreeView represents a data element from the XML file.
Populate the TreeView
To populate the TreeView, we will loop through the XML nodes and create corresponding TreeView nodes for each node. We will assign the appropriate attributes, such as the node's text, value, and parent-child relationships. By adding these nodes to the TreeView control, we can visually represent the XML data in a structured manner.
Additionally, we can enhance the user experience by customizing the appearance of the TreeView nodes, such as setting icons, colors, and styles. This allows for better visualization and interaction with the XML data.Full Source VB.NET
