Asp.Net and the single file model, update panel

I have used the control kit without any problems on the 2 file model.

I am currently having to work with someone that started a project in the single file model. I am wanting to use some of the same functionality that I have used in the 2 file model but it is doing a full postback.

 ID="upGridIssues" runat="server">
            
            
            
                 ID="ddlGameIssueTypes" runat="server" 
                    OnSelectedIndexChanged="ddlGameIssueTypes_SelectedIndexChanged" 
                    AutoPostBack="True">
                     Selected="True">Select Issue Type
                    Account Issue
                    Functionality
                    Game Glitch
                    Page Error
                    Suggestion
                
                 ID="gvIssues" runat="server" HeaderStyle-CssClass="HeaderStyle" RowStyle-CssClass="RowStyle"
                    AlternatingRowStyle-CssClass="AltRowStyle" EditRowStyle-CssClass="EditRowStyle"
                    PagerStyle-CssClass="PagerStyle" AllowPaging="True" AllowSorting="False" AutoGenerateColumns="false"
                    CssClass="GridViewStyle" GridLines="Horizontal" PageSize="20">
                    
                         ShowSelectButton="true" SelectText="Edit" />
                         DataField="Message" HeaderText="Message" SortExpression="Message">
                             Width="650px" />
                        
                         DataField="User" HeaderText="User" SortExpression="User">
                             Width="200px" />
                        
                         DataField="Date" HeaderText="Date" SortExpression="Date">
                             Width="150px" />
                        
                         DataField="Status" HeaderText="Status" SortExpression="Status">
                             Width="75px" />
                        
                    
                
            
        

 
No matter what i can not get the single file model to do this asynchronously, it always reloads the page fully. 
Is it possible to do it in the single file model or am I doing something wrong?
