Default Button - ASP.NET (Elementary ?)

[Al Mowbray]

I would like to set a button as the default button (hitting 'Enter' is the
same as clicking the button), but don't see a property for this, yet many
web apps have this functionality. How does one go about doing this?

Thanks.

Put the following code into your Page_Load event:

Page.RegisterHiddenField("__EVENTTARGET", "Button1")

changing "Button1" to the name of your default button.

Note: This relies on the following client-side script that VS .NET puts in the
code behind page:

<script language="javascript">
<!--
function __doPostBack(eventTarget, eventArgument) {
var theform = document.Form1;
theform.__EVENTTARGET.value = eventTarget;
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->
</script>


So this solution works only if the visitor’s browser supports and has enabled
client-side scripting.

Hi,

I tried this as well but it doesn't seem to work for me. I have a calendar,
2 textbox and 3 button controls (webcontrols) on my page.
The script is generated in the HTML, the __EVENTTARGET is properly set in
the HTML but the ENTER stroke still invokes the first button painted.

Did I miss something ?

Johan.
