ASP.NET C# Checkbox Realtime Validation

Question
Trying to get two checkbox controls to work with each other. Pseudo-code example:
If Checkbox 1 is checked,
Look at checkbox 2 and make sure it is not checked.
If checkbox 2 is checked, then uncheck Checkbox 2.
and Vice Versa.
I kind of have it, but it wont update until I press a submit button. Is there a way to run the pseudo-code without pressing submit first? I tried using:
<asp:CheckBox ID="World1" runat="server" OnCheckedChanged="World1Changed" />
but in the codebehind file it still won't update without pressing submit.
Solution
Just add AutoPostBack="true"
to your checkbox.
