TreeView Data Binding Guide

There are two methods to bind data to a TreeView control.

1. Bind data through code:
   By writing code, connect the data source to the TreeView control. You can use the DataSource and DataMember properties of the TreeView to bind the data source to the TreeView control and specify the node relationships in the data source. Then, by calling the DataBind method of the TreeView, bind the data source to the control.
2. Data binding expressions are used to bind data:
   In ASP.NET Web Forms, data binding expressions can be used to directly bind a data source to a TreeView control. Data binding expressions can be used in the node tags of a TreeView to bind properties such as text, value, and selected status. Data binding expressions use the <%# %> syntax, where binding expressions, functions, or data source fields can be used to dynamically set property values.

Both methods can bind data to the TreeView control based on the structure and needs of the data source, allowing for dynamic display and manipulation of data.
