    Hi everyone, I have TreeView and shows some Data from DB. And I'd like to get content of clicked node from the DB. I mean when I click some node, it must brings some content related node from DB to another table or div. Can you help me about it?

    Hmm, I thought someone replied in a short time, but not :) Anyway, If anyone don't understand or don't know how to do it but at least can someone tell me how to get SelectedNode's ID and keep it a Session or get it by using JavaScript?

    Hello,

    Attach handler to the OnNodeClick event and inside that it is possible to get the clicked node text and value. I hope this is suitable for your scenario.

    [ASPX]
     
    <telerik:radtreeview id="RadTreeView1" runat="server" OnNodeClick="RadTreeView1_NodeClick"> 
    <Nodes> 
      . . . 
    </Nodes> 
    </telerik:radtreeview> 

    [CS]
     
    protected void RadTreeView1_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e) 
    { 
        String clickedNodeText = e.Node.Text; 
        String clickedNodeValue = e.Node.Value;     
        //Use Sql query to get the content from database according to selected node 
    } 
    Please feel free to correct me if I have not got your scenario right.

    Thanks,
    Shinu.

    Thanks Shinu, for your interest and your example, but I just solved my problem, it was easier than I guess.

    I do it with : "RadTreeView.SelectedNode.Value" method ;)
