Hey everyone. My team and I were excited to implement the new Q3 release into our application, but we're experiencing strange UI problems. Since the problems are crippling, I haven't investigated the extent of the damage yet, but the main one we're experiencing is as follows. Any page with RadComboBox controls, at least inside of a RadPanelBar, fail to render any data and fail to include any skinning, ie triangle image, hover behavior, etc. However, after collapsing and re-expanding the panel item, the controls render fine.

We do not have any RadComboBox controls outside of a RadPanelBar control to my knowledge, so I'm not sure if the problem is directly related to the RadComboBox, the RadPanelBar, or elsewhere. We haven't had any other trouble like this in the past. I've done some researching of problems related to the Q3 release, and haven't found any, so hopefully this is not an actual bug with the controls. If you've gotten any reports or ideas as to the source of this problem, help would be appreciated.

Thanks,

Adam.g

Hi Adam,

First of all, I am sorry to hear you are having a problem upgrading to the new version of the controls. Would you mind providing more specific details as to how you are implementing your RadComboBox and RadPanelBar controls?

I created a simple example of a RadPanelBar containing two RadComboBox controls and it worked perfectly. Here is the source for my example:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="_Q3._08._0__RadComboBox_Inside_a_RadPanelBar._Default" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

                <title>Example - RadComboBox Inside a RadPanelBar</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <telerik:RadScriptManager ID="RadScriptManager1" runat="server" /> 
        
                    <telerik:RadPanelBar ID="RadPanelBar1" runat="server"

                                        DataTextField="CompanyName" 
        
                                        DataValueField="CustomerID"> 
        
                                    </telerik:RadComboBox> 
        
                                </ItemTemplate> 
        
                            </telerik:RadPanelItem> 
        
                            <telerik:RadPanelItem Text="Products">

                            </telerik:RadPanelItem> 
        
                        </Items> 
        
                    </telerik:RadPanelBar> 
        
                    <asp:SqlDataSource ID="SqlDataSource1" runat="server"  
        
                        ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"  
        
                        SelectCommand="SELECT [CustomerID], [CompanyName] FROM [Customers]"> 
        
                    </asp:SqlDataSource> 
        
                    <asp:SqlDataSource ID="SqlDataSource2" runat="server"  
        
                        ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"  
        
                        SelectCommand="SELECT [ProductID], [ProductName] FROM [Products]"> 
        
                    </asp:SqlDataSource> 
        
                </form> 
        
            </body> 
        
            </html>

Perhaps if you could provide further details about your project or maybe even some source code that would help me figure out what is causing the problem in your application.

Sure. The only real difference that I can see between the way we implement the panelbar is in the nesting of items, which you have shown one deep. To my knowledge, the way to get collapsible panels is to nest two deep, thusly:

    
            <telerik:RadPanelBar ID="CreateUsesPanelBar" runat="server" Skin="Office2007" CssClass="collapsible" Width="100%"> 
        
                    <CollapseAnimation Duration="100" Type="None" /> 
        
                      <Items> 
        
                        <telerik:RadPanelItem runat="server" Text="Use Identification" Expanded="True"> 
        
                          <Items>                 
        
                            <telerik:RadPanelItem runat="server"> 
        
                              <ItemTemplate>  
        
                  <telerik:RadAjaxPanel ID="UseIDRadAjaxPanel" runat="server">

This code has worked fine against all previous DLL releases. I also see you don't do any server value binding on the ComboBoxes, which we do throughout the application, but I'm pretty sure that I have tested this as well. Again, this code would be inside the sliding pane of a RadSplitter, and that may be the only set of differences I can see between these two samples.

Thanks a lot,

I have indeed done that, and my ticket number is 174777.

As an aside, it didn't take much code to recreate this problem. I see that the above code sample does work; just the PanelBar alone.
However, stick the same scenario inside of a RadSplitter, and that's when it fails. The code below was tested without styles, so you can ignore any css class settings.

Admittedly, our team is a little busy to look to deeply into this problem at the moment, but unless it's something simple like a misplaced or missing attribute, or broken tags, the Q2 release DLL is working fine for us for the time being.

Thanks for the help,
