    When setting the selected items using SelectedValue the display text is not being updated. If I expand the dropdown I see the checkboxes selected but the displayed text is empty.

    If I select a node it will update the displayed text but until then it is empty. Am i missing something?

    Version 2015.1.401.40

        DefaultMessage="Please select" 

    Protected Sub rddtTo_DataBound(sender As Object, e As System.EventArgs)
       DirectCast(sender, Telerik.Web.UI.RadDropDownTree).ExpandAllDropDownNodes()
       rddtTo.SelectedValue = hdnSelectedValues.Value
    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       If Not Page.IsPostBack Then
          Using p_Db As New mlDB("Messages_Template_List", -1)
             p_Db.SQL = "Messages_Groups_Select"
             rddtTo.DataSource = p_Db.GetDataTable
          End Using
       End If
    End Sub

    You are correctly setting the RadDropDownTree's SelectedValue property in the NodeDataBound event handler so looking at your code I think the value that you pass to the property could be what is preventing the nodes from being displayed in the entry area.

    You can debug the project, put a break point in the rddtTo_DataBound event handler and check the value of "hdnSelectedValues.Value".
