Hi,
I have a simple page with a panel which contains a RadComboBox. When i dynamically set the panel to enable=false, the combo box also gets disabled appropriately. When i try to set the panel back enable=true, the combo box does not get re enabled.
I tried this with other Prometheus controls (i.e RadGrid), and they have behaved correctly

Here is this code to replicate this:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="PanelComboTest.aspx.cs" Inherits="PanelComboTest" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server"> 
        
                    </asp:ScriptManager> 
        
                <asp:RadioButtonList ID="radioList" runat="Server" AutoPostBack="true"> 
        
                <asp:ListItem Text="disable" Value="0"></asp:ListItem> 
        
                <asp:ListItem Text="enable" Value="1"></asp:ListItem> 
        
                </asp:RadioButtonList> 
        
                <div> 
        
                <asp:Panel ID="myPanel" runat="server"> 
        
                    <telerik:RadComboBox ID="RadComboBox1" runat="server" RadComboBoxImagePosition="Right"> 
        
                    <Items> 
        
                    <telerik:RadComboBoxItem Text="item1" Value="1" runat="server" /> 
        
                    <telerik:RadComboBoxItem Text="item2" Value="2" runat="server" /> 
        
                    </Items> 
        
                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                        <ExpandAnimation Type="OutQuart" /> 
        
                    </telerik:RadComboBox> 
        
                </asp:Panel> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

And the code behind:

    
            using System; 
        
            using System.Data; 
        
            using System.Configuration; 
        
            using System.Collections; 
        
            using System.Web; 
        
            using System.Web.Security; 
        
            using System.Web.UI; 
        
            using System.Web.UI.WebControls; 
        
            using System.Web.UI.WebControls.WebParts; 
        
            using System.Web.UI.HtmlControls; 
        
            public partial class PanelComboTest : System.Web.UI.Page 
        
            { 
        
                protected void Page_Load(object sender, EventArgs e) 
        
                { 
        
                    this.radioList.SelectedIndexChanged += new EventHandler(radioList_SelectedIndexChanged); 
        
                    if (!this.IsPostBack) 
        
                    { 
        
                        radioList.SelectedIndex = 0; 
        
                        myPanel.Enabled = false; 
        
                    } 
        
                } 
        
                void radioList_SelectedIndexChanged(object sender, EventArgs e) 
        
                { 
        
                    if (radioList.SelectedValue == "0") 
        
                    { 
        
                        myPanel.Enabled = false; 
        
                    } 
        
                    else 
        
                    { 
        
                        myPanel.Enabled = true; 
        
                    } 
        
                } 
        
            }

Hi EmpowerIT,

Please find attached the latest internal build of the control. This should solve the problem.

Give it a try and let us know how it goes.
