how to check if there's a selected node in the treeview (resolved)

[fret]

maybe this is simple but i'm in a hurry and i have no idea about this in treeview. I need to know how to check if there is there is selected node in the treeview.
Like in the listview is like this. lstProperty.SelectedItems.Count > 0 to determine you select 1 item on it, just don't know what is the equivalent in the treeview on selecting a node.

Thanks in advance.

Try

Treeview1.SelectedNode

i've already tried that but seems not working.

Can you post the code that you're using?

The selectednode should only return a single node object rather than a collection like the listview. Treeviews only allow single selection whereas a listview provides an option to multiselect.

ok i figure it out lil thanks for the advice, but my problem now is this. I have a parent node called "node0" and has a child "node1". When i click a button i want "node0" to appear in a textbox seems okey, but my concern is when i select "node1" it appears in the textbox as "node1" and i want it appear as "node0" which is the parent of the "node1".

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If TreeView1.SelectedNode.Parent.IsSelected Then 'Object reference not set to an instance of an object
            TextBox1.Text = TreeView1.SelectedNode.Text
        Else
            TextBox1.Text = TreeView1.SelectedNode.Parent.Text 'this work if the child node is selected and it appears in the textbox the parent node
        End If
    End Sub

i think my code is wrong but i need some help to get in the right way.
