TreeView leaf node style programmatically
The TreeView is an asp.net web server control. The TreeView is located
under System.Web.UI.WebControls namespace. TreeView web server control
displays hierarchical data. Such as a table of contents in a tree
structure.
The following asp.net c# tutorial code demonstrates how we can programmatically change the TreeView web server control’s leaf node style. The asp.net c# developers can set the TreeView leaf node style using its LeafNodeStyle property.
The TreeView LeafNodeStyle property gets a reference to the TreeNodeStyle object that allows you to set the appearance of leaf nodes. The TreeView LeafNodeStyle property value is TreeNodeStyle which is a reference to the TreeNodeStyle that represents the style of the leaf nodes in the TreeView.
The TreeNodeStyle class represents the style of a node in the TreeView control. The TreeView control allows us to specify different style characteristics such as font size and color for each of the different node types.
In this asp.net c# tutorial, we changed the TreeView leaf node’s various styles such as background color, text color, border color, border width, and font style using its LeafNodeStyle property.
