How do I associate the Enter key with a button on an ascx page?

I have a button on one of my content pages which i need to fire on hitting the enter button. I tried specifying the default button in the updatepanel but without any avail. If you have 开发者_如何学JAVAa solution for the same please let me know. Thanks in advance.

Use the panel control and setup your button with DefaultButton="Button1"

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
 .................................
 ...............your contents..................
 </asp:Panel>

You can also use javascript, which you can call from the textbox's key press event,

function checkKey(b1, e) {
if (e.keyCode == 13) {
    document.getElementById(b1).click();
    return false;
}    }

Hope this will helps...
