Hi there,

It seems you are using some older version of the control that is not compatible with IE8. Please update to at least Q1 2009 SP1 and let us know how it goes. In addition, please find attached a screenshot that shows the proper work of the latest version under IE8 Standards mode.

Test code snippet:

    
            <form id="form1" runat="server"> 
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                </telerik:RadScriptManager> 
        
                <telerik:RadComboBox ID="RadComboBox1" runat="server" MaxHeight="100px"> 
        
                    <Items> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem2" Value="RadComboBoxItem2" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem3" Value="RadComboBoxItem3" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem4" Value="RadComboBoxItem4" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem5" Value="RadComboBoxItem5" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem6" Value="RadComboBoxItem6" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem7" Value="RadComboBoxItem7" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem8" Value="RadComboBoxItem8" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem9" Value="RadComboBoxItem9" /> 
        
                        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem10" Value="RadComboBoxItem10" /> 
        
                    </Items> 
        
                </telerik:RadComboBox> 
        
                </form>

Hi Paul,

Thanks for your reply and for the screenshot. I am definitely using the latest release (2009.2.701.35). However, the issue may be that I'm using the Q3 2008 compatible skins and also may have injected some hacks to make it look the way I wanted it to in IE7.

I've discovered that if I invoke either the IE 8 Compatibility View Browser mode or the IE7 Standards Document Mode the combobox will display properly. My second issue was that I had tried to invoke IE7 emulation by placing the following tag in my masterpage but it wasn't having any effect:

I had placed it as the last <meta> tag in the <head> section, and I discovered that if I moved it to the top of the list of <meta> tags then it IE8 emulated IE7 and the combobox looked correct! Go figure. Ultimately I've decided to implement the X-UA-Compatible setting as a response header using the info from this article: http://msdn.microsoft.com/en-us/library/cc817572.aspx

Hello Tim Mackay,

I am sorry for the troubles. It was not an easy decision to change the skins and we alerted about that beforehand and created a tool for migration.

So, I suppose that your case is this: you use the 2009.2.826 release with the Gray skin converted for that release as described here. Is that correct? Did you use the ASP.NET Theme approach or the Direct Skin registration one? I need that information so we can prepare the environment at our side to reproduce the exact case and find you a solution.

Thank you for your patience.

Best wishes,
