Hi friends,

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,
                        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.
