Hello!

I'll restate my question:

I have this code to create new nodes when i click on drilldown button, but, not show the new nodes.

What do I lack? what am I doing wrong?

Protected Sub RadOrgChart1_DrillDown(ByVal sender As Object, ByVal e As Telerik.Web.UI.OrgChartDrillDownEventArguments) Handles RadOrgChart1.DrillDown

        Dim node = TryCast(e.SourceNode, OrgChartNode)
        If e.SourceNode.Nodes.Count > 0 Then
            e.SourceNode.Nodes.RemoveRange(0, e.SourceNode.Nodes.Count - 1)
        End If
        'get employee from database
        Dim ct As DataTable = clsOrgChart_2.orgChart_getUsers(e.SourceNode.ID).Tables(0)
        'add employees into node.
        For Each itemRow As DataRow In ct.Rows
            Dim nNode As New Telerik.Web.UI.OrgChartNode
            nNode.DataItem = itemRow
            node.Nodes.Add(nNode)
        Next
    End Sub

 

 

Thank you! :)

Hi Carlos,

May I ask you to give as a bit more details of your implementation. What is you RadOrgChart markup declaration and how do you initially load the root nodes?
