Hi Chris,

If you use version earlier than 2008.1.515 you can use the following workaround:

1.Modify the definition of the buttons which export files and attach them to OnClientClick event like this:

    
            <asp:ImageButton ID="ImgExportToExcel" runat="server" OnClick="ImgExportToExcel_Click"   
        
            Style="margin-left: 6px; margin-right: 3px;" ImageUrl="~/Global/Images/icons/icon_excel_16.gif"   
        
            ImageAlign="AbsMiddle" meta:resourcekey="ImgExportToExcel" OnClientClick="javascript:return Test();"   /> 
        
            <script type="text/javascript">   
        
            function Test()   
        
            {   
        
                    document.location.href="ReviewContactNames.aspx?stream=ImgExportToExcel_Click";   
        
                    return false;   
        
            }   
        
            </script>

2.Move the code exporting files from the button's click event handler to the page_load event handler :

    
            Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)  
        
                If Request.QueryString("stream") = "ImgExportToExcel_Click" Then  
        
                      GridOccupancies.ExportSettings.ExportOnlyData = True 

                    GridOccupancies.MasterTableView.ExportToExcel()
        
                End If  
        
            End Sub

If you use version 2008.1.515 you can use the first workaround on the following:
1.Add a script reference to the ScriptManager

    
                <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                        <Scripts> 
        
                            <asp:ScriptReference Path="InitScript.js" /> 
        
                        </Scripts> 
        
                    </asp:ScriptManager>

2.Override setIsInPostBack method of RadComboBox in the following way:
InitScript.js

    
            // Hook up Application event handlers.       
        
            var app = Sys.Application;       
        
            app.add_init(ApplicationInit);       
        
            function ApplicationInit(sender) {       
        
            Telerik.Web.UI.RadComboBox.prototype.setIsInPostBack = function(isInPostBack)    
        
            {    
        
            }    
        
            }

Hope this helps.
