From a control's onkeypress the below javascript snippet is executed. I am
attmpting to set the value of a hidden field... I believe I'd be able to get
the contents of the hidden field by using
"Page.Request.Item(MyHiddenFieldName)" sever-side, no? Unfortunately the
field doesn't look like it's even being set. Is there something special I
need to do?

TIA,
Paul

if (event.keyCode == 13)
{
event.returnValue=false;
event.cancelBubble = true;
document.forms[0].MyHiddenFieldName.Value='something';
document.forms[0].submit();
}
 
....

After the page is submitted, yes, I've always used:

Dim hiddenValue as string

hiddenValue = Request.Form("hiddenFieldName")

You could always change the hidden field to a normal text box, just
temporarily, then you would actually "see" if the javascript was setting the
value of the control.
 
your client script is wrong. javascript is case sensitive you you are
dynamically creating a "Value" property and setting its value. of cource
this is not posted back. try:

document.forms[0].MyHiddenFieldName.value='something';

I changed it as you suggested but the value still isn't being set. :(

The funny thing is, when I remove the hidden field, I get a JavaScript
error, so I know it's being referenced properly. Really wierd.
