Ok, so I've got a template field in a gridview that contains just a simple button...

            <asp:GridView ID="KeywordsGridView" AllowPaging="false" AutoGenerateColumns="false" BackColor="white"
                GridLines="None" HeaderStyle-CssClass="Table_Header" RowStyle-CssClass="Table_Style" 
                runat="server">
                <Columns>
                    <asp:TemplateField>
                        <ItemTemplate>
                            <asp:Button runat="server" />
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:BoundField DataField="References" SortExpression="References" HeaderText="Total References" />
                    <asp:BoundField DataField="Keyword" SortExpression="Keyword" HeaderText="Keyword" />
                </Columns>
            </asp:GridView>

Whenever I click the button I get the error...

Invalid postback or callback argument.  Event validation is enabled using 
<pages enableEventValidation="true"/> in configuration or <%@ Page 
EnableEventValidation="true" %> in a page.  For security purposes, this feature 
verifies that arguments to postback or callback events originate from the server 
control that originally rendered them.  If the data is valid and expected, use the 
ClientScriptManager.RegisterForEventValidation method in order to register the 
postback or callback data for validation. 

I've found a decent amount of articles referencing this issue, including a couple on SO, for example...

http://stackoverflow.com/questions/228969/asp-net-invalid-postback-or-callback-argument-event-validation-is-enabled-usi

and...

http://stackoverflow.com/questions/103560/invalid-postback-or-callback-argument

I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?
