Calling a button event without postback

[Lulubelle]

I have a button that I want to function like normal, except I don't want it to postback.If a user clicks it, I want to execute the Button Click event on the next postback, I just don't want that particular button to be able to postback.I tried this:\[code\]<asp:Button ID="ChangeAllBtn" runat="server" Text="Change All" OnClientClick="return false;" OnClick="ChangeAllBtnClick" />\[/code\]But it doesn't call the ChangeAllBtnClick after I postback.If I remove the "return false;", then there is postback before I want it.What do?
