With this TreeView declaration:

<asp:TreeView ID="Cloner" runat="server"

    SelectedNodeStyle-Font-Bold="true" SelectedNodeStyle-ForeColor="#003E21"

    OnTreeNodePopulate="PopulateNode" OnSelectedNodeChanged="SelectNode"

    ExpandDepth="0">

</asp:TreeView>

Nodes are added in PopulateNode() like so:

protected void PopulateNode(Object source, TreeNodeEventArgs e)

{

    TreeNode newNode = null;

    switch (e.Node.Depth)

    {

        case 0:

        string locationIdStr = e.Node.Value;

        try

        {

        int locationId = Convert.ToInt32(locationIdStr);

        e2006TableAdapters.MenusTableAdapter mta = new e2006TableAdapters.MenusTableAdapter();

        mta.FillByLocationId(myDto.Menus, locationId);

        foreach (e2006Table.MenusRow menuRow in myDto.Menus)

        {

        newNode = new TreeNode(menuRow.MenuName, menuRow.MenuId.ToString());

        newNode.SelectAction = TreeNodeSelectAction.Expand;

        newNode.PopulateOnDemand = true;

        e.Node.ChildNodes.Add(newNode);

        }

        }

        catch { }

        break;

// etc

And, finally, the leaf nodes are added with this code:

foreach (e2006.MenuItemsRow menuItems in myDto.MenuItems)

{

    newNode = new TreeNode(menuItems.Name, menuItems.MenuItemId.ToString());

    newNode.SelectAction = TreeNodeSelectAction.Select;

    newNode.NavigateUrl = "";

    e.Node.ChildNodes.Add(newNode);

}

The question is: WHY doesn't the OnSelectedNodeChanged="SelectNode"

protected void SelectNode(Object source, EventArgs e)

{ // This never fires!!!???!!!



TIA,

Hi geo,

We have reviewed this issue and are currently researching on it. We will
update you ASAP. Thanks for your patience!

Hi Geo,

Sorry for keep you waiting. As for the dynamically added TreeNode's
Selected event not fire problem, based on my research , it is due to the
TreeNode.SelectAction you set in the original code...

In order to make the "TreeNodePopulated" and "SelectedNodeChanged" event
get fired for your new created nodes, we should set their SelectAction to 
"SelectExpand", e.g:

================================

protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs
e)
    {
        string name = e.Node.Text;
        TreeNode node = null;
        if (e.Node.ChildNodes == null || e.Node.ChildNodes.Count == 0)
        {
            for (int i = 0; i < 5; i++)
            {
                node = new TreeNode(name + i, name + i);
                node.SelectAction = TreeNodeSelectAction.SelectExpand;
                node.PopulateOnDemand = true;

                e.Node.ChildNodes.Add(node);
            }
        }
    }
=====================================

Hope helps. Thanks,

Dear Sir,

I would like to check if the dynamically load nodes can still fire the

onselectednodechanged. Even if I changed to SelectExpand, it still does
not work. My code

is as follows. Please help. Thanks.



best regards,

Edward



<ASP:TreeView id="TreeView1" OnTreeNodePopulate="TreeNodePopulate"

OnSelectedNodeChanged="TreeNodeSelectedNodeChanged" ExpandDepth="0"
EnableViewState="false"

Visible=False ShowLines="true" runat="server"></ASP:TreeView>

        Sub TreeNodeSelectedNodeChanged(ByVal sender As Object, ByVal e
As EventArgs)
            Value = TreeView1.SelectedNode.Value
            Text = TreeView1.SelectedNode.Text
            TreeView1.Visible = False
        End Sub
        Sub TreeNodePopulate(ByVal sender As Object, ByVal e As
TreeNodeEventArgs)
            SetDV()
            Dim nodes As DataView = GetChilds(DV, e.Node.Value)
            ' Populate Treeview.
            For Each row As DataRowView In nodes
                Dim newNode As New TreeNode()
                newNode.Text = row("description").ToString()
                newNode.Value = row("code").ToString()
                'If Not IsNumeric(newNode.Value) Then
                newNode.SelectAction = TreeNodeSelectAction.SelectExpand
                newNode.PopulateOnDemand = True
                'End If
                e.Node.ChildNodes.Add(newNode)
                'AddChild(DV, headNode)
            Next
        End Sub
