    Hi friends,
           In my page i used radtreeview and binded this radtreeview dynamically with database. when i click on expand symbol (+) radtreeview  not expanding. when i click on root node (AF - Angel Falls) it's working fine. Root node expand not working at first time after that it's working fine.

    Please find the screen shot of my radtreeview and please provide me the solution.

    Hello Nagendra,

    Is there an error thrown, when you try to expand using the plus sign?
    Could you, please, post an example reproducing the problem?

    Hi Nikolay Tsenkov,

      No error in my page, but not working plus sign(+) in radtreeview.

    Hi Nikolay Tsenkov,
                            Binded radtreeview dynamically like this.

      BuildTreeView function for binding parent nodes to radtreeview
                
    Private Sub BuildTreeView()
          Dim data As DataTable = GetData(New MySqlCommand("SELECT distinct null as 'parent_id', vc.id as 'child_id', vc.code as 'child_code' from vw_community vc INNER JOIN min_com_lots mcl ON mcl.community_id = vc.id INNER JOIN tsm_schedule ts ON mcl.com_lot_id = ts.com_lot_id INNER JOIN tsm_schedule_activities_publish_s tsaps ON tsaps.schedule_id = ts.schedule_id And tsaps.user_id =" + Session("SelUserID")))
          For Each row As DataRow In data.Rows
              Dim node As New RadTreeNode()
              node.ContextMenuID = "contextMenu1"
              node.Text = row("child_code").ToString()
              node.Value = row("child_id").ToString()
              'TreeView.Nodes.Add(node)
              RadTreeView1.Nodes.Add(node)
              node.ExpandMode = True
              RadTreeView1.Nodes.Add(node)
          Next
      End Sub
               function for radtreeview node click
    Protected Sub RadTreeView1_NodeClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.NodeClick
            ddlFilters.SelectedItem.Text = "Select Filter"
            PopulateNodeOnDemand(e, TreeNodeExpandMode.ServerSideCallBack)
        End Sub
    same thing i written for radteeview node expand
    Protected Sub RadTreeView1_NodeExpand(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs)
            ddlFilters.SelectedItem.Text = "Select Filter"
            PopulateNodeOnDemands(e, TreeNodeExpandMode.ServerSideCallBack)
            contextmenu()
        End Sub
    this function is not responding at parent level(at first time), but when i clicking on parent node node click function working fine. After node click event node expand event working fine.

    Thanks,
    Nagendra.

    Hi Nagendra,

    I tried to reproduce the issue that you encounter but with no success. Please take a look at the page that I have attached. When I click on a node it expands the node and populates it and when I click on the plus/minus sign it expands/collapses the node as expected. For the test I used the 2011.2.712.35 version of the controls.

    Hi,
        I checked your sample code, it's working fine.
        I implemented same thing in my project with radtreeview properties, it's not working.

        I will provide the login access to my site. Please check the my issue.
       
      
    Thanks and Regards,
    Nagendra.
