OnEntryAdded doesn't fire in RadDropDownTree When I Change the Value of the DropDownTree

Question

I Have This in the ascx

<div >
<telerik:RadDropDownTree ID="RadDropDownTree1" runat="server" Width="250px" EnableFiltering="True"
    Skin="Metro" DataFieldID="ID" DataFieldParentID="Parent" DataTextField="Name" DataValueField="Code" 
    OnEntryAdded="RadDropDownTree1_EntryAdded1" OnEntryRemoved="RadDropDownTree1_EntryRemoved1">
    <dropdownsettings height="200" AutoWidth="Enabled" />
    <buttonsettings showclear="false" />
    <filtersettings highlight="Matches" emptymessage="Type here to find a Department" />
</telerik:RadDropDownTree>
</div>

and in the server side

protected void RadDropDownTree1_EntryAdded1(object sender, DropDownTreeEntryEventArgs e)
{
    throw new NotImplementedException();
}

protected void RadDropDownTree1_EntryRemoved1(object sender, DropDownTreeEntryEventArgs e)
{
    throw new NotImplementedException();
}

1. Try setting AutoPostBack to true.

2. Make sure AutoEventWireUp in your Page Directive is set to true
