SelectednodeHello,
I am able to GET the selected node with my code. I would however like to SET any node with code. Something like me.treeview.selectednode="First" But this doesn't work. I can't find anything on setting this property. Can you help?

I hear what your saying, but I'm afraid I can't do it.
I have one parent node, node1 and three child nodes, child1, child2, child3. They are fixed and don't change. They all have a tag, parent, one, two and three. Making things happen when I select them is no problem. But when the form loads, I want child1 to be selected, not parent. So lets say I want code to select child3 by tag or lable what is the code for doing so? Forgive me, but I am learning by copying code and changing it to my needs. "objects" "classes" and so on are only words to me. I know I have to learn, but for now I'd like to keep it simple.

To select the first node as the selected node:\\\ Me.TreeView.SelectedNode = Me.TreeView.Nodes(0) /// To select a different node you will need to locate the appropriate Node within the Nodes collection, and then pass that to the SelectedNode property. -- (O)enone Now that's something I can work with, thanks!
Me.tvwMenu.SelectedNode = Me.tvwMenu.Nodes(0).Nodes(0) did the trick.

I have a revision already :) (i have added an if to the first sub) Please suggest improvements if any... -tommaso Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Me.TreeView1.HideSelection = False Me.TreeView1.Nodes.Clear() Me.TreeView1.Nodes.Add(New TreeNode("Hello")) TreeView_EnsureFirstNodeIsSelectedIfExist(Me.TreeView1) 'Force selection again TreeView_ForceSelectFirstNodeIfExist(Me.TreeView1) End Sub Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect MsgBox("Selected " & e.Node.Text) End Sub Sub TreeView_EnsureFirstNodeIsSelectedIfExist(ByVal Treeview As TreeView) If Treeview.Nodes.Count = 0 Then Exit Sub If Treeview.SelectedNode IsNot Treeview.Nodes(0) Then Treeview.SelectedNode = Treeview.Nodes(0) End Sub Sub TreeView_ForceSelectFirstNodeIfExist(ByVal Treeview As TreeView) If Treeview.Nodes.Count = 0 Then Exit Sub If Treeview.SelectedNode IsNot Nothing Then Treeview.SelectedNode = Nothing Treeview.SelectedNode = Treeview.Nodes(0) End Sub End Class tommaso.gasta***@uniroma1.it ha scritto: Show quoteHide quote > Hi jerry, > > Sub TreeView_EnsureFirstNodeIsSelectedIfExist(ByVal Treeview As > TreeView) > If Treeview.Nodes.Count = 0 Then Exit Sub > Treeview.SelectedNode = Treeview.Nodes(0) > End Sub > > > usually one wishes that the AfterSelect event be fired even though the > node is selected already (for 2003 replace isNot with if not...is): > > > Sub TreeView_ForceSelectFirstNodeIfExist(ByVal Treeview As > TreeView) > If Treeview.Nodes.Count = 0 Then Exit Sub > If Treeview.SelectedNode IsNot Nothing Then > Treeview.SelectedNode = Nothing > Treeview.SelectedNode = Treeview.Nodes(0) > End Sub > > example > > Public Class Form1 > > Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As > System.EventArgs) Handles Button1.Click > > Me.TreeView1.HideSelection = False > Me.TreeView1.Nodes.Clear() > Me.TreeView1.Nodes.Add(New TreeNode("Hi Jerry")) > > TreeView_ForceSelectFirstNodeIfExist(Me.TreeView1) > > End Sub > > Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, > ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles > TreeView1.AfterSelect > MsgBox("Selected " & e.Node.Text) > End Sub > > End Class > > -tommaso > > > > > Jerry ha scritto: > > > Hello, > > > > I am able to GET the selected node with my code.
