Set an async trigger for an Update Panel with a GridView asp:ButtonField

What is correct sytnax for setting an AsyncPostBackTrigger for an UpdatePanel with an asp:ButtonField from an GridView control?

I need to set an 'AsyncPostBackTrigger' for each asp:ButtonField in my GridView

Here is my source code

<asp:UpdatePanel ID="MyUpdatePanel" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
    <Triggers>
    </Triggers>
    <ContentTemplate>
        <asp:GridView ID="MyGridView" runat="server" AutoGenerateColumns="false">       
            <Columns>        
                <asp:ButtonField ButtonType="Link" CommandName="Button1" SelectText="Click Me!" />        
                <asp:ButtonField ButtonType="Link" CommandName="Button2" SelectText="No Click Me!" />    
            </Columns>
        </asp:GridView>
    </ContentTemplate> 
</asp:UpdatePanel>

Update

I need to keep the UpdateMode and ChildrenAsTriggers attributes set to true because the I have other button contained within the UpdatePanel that do not refresh the UpdatePanel control

Could you use a template field instead of a command field, and forcibly update (UpdatePanel.Update()) the panel when the command button is clicked?

Everything that Lance Harper mentioned is true, but you also need to remove the following attribute:

UpdateMode="Conditional"

Having that attribute in place will prevent the automatic wire-up of your client side events. Essentially you are telling ASP.Net that you are going to do this yourself.

The ChildrenAsTriggers property being set to true will cause any control that causes a postback within the update panel to cause it to refresh. You would only need to use the triggers element if you had a control outside of the update panel you wished to use to trigger the refresh of that update panel. You don't even need the triggers element in this instance.
