AJAX 101 -- event not firing

[John Mott]

This is a total ID-10T error, but since its my first attempt I'm missing the
obvious.

I downloaded the framework, create an AJAX enabled app, added a page, and
added an update panel with this:

<asp:UpdatePane l ID="updateCateg ory" runat="server">
<ContentTemplat e>
<asp:CheckBox runat="server" ID="chkCategory "
OnCheckedChange d="chkCategory_ OnCheck" />
</ContentTemplate >
</asp:UpdatePanel >

However, the event isn't firing on click, the events are queued until the
next page refresh. Is there a 'hey dummy' checklist? No errors, just no
events.

thanks,

john

if you want the checkbox to post to the server when chcecked, set
AutoPostBack = true

Thank you, that was it. I guess I assumed that putting it in a panel implied
a server hit, but it makes more sense to have the controls do what they
normally do.

Thank you again. The next thing i found was that I can't figure out how to
pass a value back in through a checkbox. It never occurred to me before that
the <asp:checkboxdi dn't have a "value" attribute, so how do you use a
checkbox to send a value (like a key value to set or clear in a collection)
back into the server?

absent this ability i'll have to implement a button and some sort of
mark/not marked state, which the checkbox is perfect for.

thanks again
