[CLOSED] HOW TO select a TreeNode of a TreePanel in code-behind - EXT.NET 2.4.x

[PoloTheMonk]

Hello,
I'm using EXT.NET 2.4.0.28408 and i'm building a tree in vb code-behind.

Here's the ext tree panel:

     <ext:TreePanel ID="charTree" runat="server" Width="300"             
        Height="550" 
        Icon="BookOpen" 
        Title="Elements" 
        AutoScroll="true">
         <Root>
         </Root>
        <BottomBar>
            <ext:StatusBar ID="StatusBar1" runat="server" AutoClear="1500" />
        </BottomBar>
        <Listeners>                    
            <ItemClick 
                Handler="#{StatusBar1}.setStatus({text: 'Selected Node: <b>' + record.data.text + '<br />', clear: false});"
                />
            <ItemExpand 
                Handler="#{StatusBar1}.setStatus({text: 'Expanded Node: <b>' + item.data.text + '<br />', clear: false});" 
                Buffer="30"
                />
            <ItemCollapse 
                Handler="#{StatusBar1}.setStatus({text: 'Collapsed Node: <b>' + item.data.text + '<br />', clear: false});" 
                Buffer="30"
                />
        </Listeners>
    </ext:TreePanel>

Here's the code-behind in vb.net:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    Dim root As New Ext.Net.Node
    Dim children As String() = {"a", "b", "c"}
 
    root.Text = "Alphabet"
    charTree.Root.Add(root)
 
    For Each c As String In children.ToList
        Dim node As New Ext.Net.Node
        node.Text = c
        node.Icon = Icon.Add
        node.Leaf = True
        root.Children.Add(node)
    Next
End Sub

The problem is that I'm trying to select a node in this tree panel, for example node with assigned text "b", and, simply, I'm not able to do it: how to?!?

Thank you in advance.

Hi @PoloTheMonk,

I would use a TreeSelectionModel's SelectedRows.
