Hi,
I have been trying for days, yes days, to use the calender from the asp.net
timetracker starter kit. I am now frustrated. I finally get the popup
calender to popup but when I click ok to insert the date to the calling page
I get the error


"A runtime error has occured

Line 14

Error: 'popUp is null or not an object'


This is the code for the page that is calling the popup. (on page load)

btnDateFrom.Attributes("onclick") =
"javascript:OpenCalendar('txtFrom',true)"

This is in the <HEAD> section of that page



<script language="javascript" src="script.js" type="text/javascript"></script>


This is the script.js



var popUp; <-----------------------note popUp here

function OpenCalendar(idname, postBack)
{
popUp = window.open('Calender.aspx?formname=' + document.forms[0].name +
'&id=' + idname + '&selected=' + document.forms[0].elements[idname].value
+ '&postBack=' + postBack,
'popupcal',
'width=270,height=260,left=200,top=250');
}

function SetDate(formName, id, newDate, postBack)
{
eval('var theform = document.' + formName + ';');
popUp.close();
theform.elements[id].value = newDate;
if (postBack)
__doPostBack(id,'');
}



This is the code for the OK button on the calender page on page load



Dim selected As String = Request.QueryString("selected")
Dim id As String = Request.QueryString("id")
Dim form As String = Request.QueryString("formname")
Dim postBack As String = Request.QueryString("postBack")

btnOk.Attributes.Add("onClick", "window.opener.SetDate('" + form + "','" +
id + "', document.Calender.datechosen.value," + postBack + ");")


Help please! The Calender popups up fine all I need now is to pass the
select data back to the main form.

Thanks

I know sir. But popup variable is at multiple places. So, it helps to see
which line that is causing error.

my guess would be that the button that opens the pop is doing a postback,
thus the var popUp is set back to undefined. you could move the close to the
popup window itself - makes more sense.

btnOk.Attributes.Add("onClick",
"window.opener.SetDate('" + form + "','" +
id + "', document.Calender.datechosen.value," + postBack +
");window.close();"
)

though on the main page you should close the popup on window unload, so as
not to leave a dangling popup window;
