Panels and Text Boxes submit twice on 'Enter'?

[kcyxa]

Hi,

Why is it that ASP.NET panels and text boxes submit twice on enter, while dropdown lists don't?

I have a panel with contols mentioned above and a javascript attached to the panel, designed to execute an imagebutton event when a user presses 'Enter'.

If a user presses enter while the focus is on the dropdown list, Page_Load event is executed, and then the imgButton_Click event. If the focus is on a text box or on the panel, then the Page_Load event is executed AGAIN after the imgButton_Click event is done.

How can I stop the second Page_Load event from executing?

Thanks,

Ks.

I got it.
Had to add a couple of lines to my JS script:
event.returnValue=false;
event.cancel = true;

function doClick(buttonName,e)
{
var key;
if (window.event) key = window.event.keyCode;
else key = e.which;

if (key == 13)
{
var btn = document.getElementById(buttonName);
if (btn != null)
{
event.returnValue=false;
event.cancel = true;

btn.click();
}
}
else
{
return true;
}
}
