Hi,

I put a checkbox tree view in a combobox and I would like to see checked items displayed in the combobox's text. However, with the codes I have, I only get selected item, not checked items:

    
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                </asp:ScriptManager> 
        
                <telerik:RadComboBox ID="RadComboBox1" runat="server" Height="200px" AllowCustomText="true" OnClientDropDownClosed="OnDropDownClosed" AutoPostBack="true">  
        
                    <ItemTemplate> 
        
                        <telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="true" TriStateCheckBoxes="true" CheckChildNodes="true" > 
        
                        </telerik:RadTreeView> 
        
                    </ItemTemplate> 
        
                    <Items> 
        
                        <telerik:RadComboBoxItem Text="" Value="" /> 
        
                    </Items> 
        
                </telerik:RadComboBox> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadComboBox1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadComboBox1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
                </form>
