Here is how you should be able to do it.

(I created the example assuming you need to show some selected Person objects in the GridView). You just need to change the following code according to your need:

C#

/// <summary>
/// Load the selected persons in the GridView
/// </summary>
private void LoadPersons()
{
       List<Person> persons = new List<Person>();
       foreach (TreeNode node in TreeView1.CheckedNodes)
       {
           string Value = node.Value; //Value could be an Id of the data
           int Id = Convert.ToInt32(Value);
           string Text = node.Text; //Text is displayed as the node value
           string path = node.ValuePath; // Path of the node from the Root Node
           Person person = GetPersonById(Id);
           if (person != null)
           {
               persons.Add(person);
           }
       }
       GridView1.DataSource = persons;
       GridView1.DataBind();
}
