 I'm clearly doing sommething dumb....

I looked at [several] forum entries on the subject and the response basically is the same

... only I can't get it to work!!!

 

here are two javascript entries:

var LblDate = document.getElementById("dnn_ctr455_PM_CalendarView_lblSelectedDate");

var LblDate1 = document.getElementById('<%=lblSelectedDate.ClientID%>');

The first works, [effectively hardcoded], the second doesn't
 
why???
 
I've tried [in addition to the above]:
var LblDate1 = document.getElementById('"<%=lblSelectedDate.ClientID%>"'); [two lots of differing quotation marks, the same QMarks etc....]
.. as well as 'losing' the QMarks AND changing the '<%=' to '<%#' and simply '&'
 
In anticipation of someone restoring my sanity.....

Above sysntax must be work. I used many times this sysntax and it works good.

so, just alert your variable so you can know what comes?

thnks..

 Hi Sahil,

I put these two lines into the Javascript file and got a 'null' response

    var LblDate1 = document.getElementById('<%= lblSelectedDate.ClientID %>');

     LblDate1);

 

I checked [twice ! :) ] , that the casing for the control was correct - it is. very frustrating....

  hi Duncan,

i send U a demo code for this. And it's working.

[CODE]

<head runat="server">
    <script type="text/javascript" language="javascript">
    function show()
    {
        document.getElementById('<%=lb.ClientID %>'));//'ll alert [obect] which is span object bcoz asp.net 2.0 render label as <span>

        document.getElementById('<%=lb.ClientID %>').innerHTML);//show label text
    }
    </script>
</head>

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label ID="lb" runat="server" Text="this is label"></asp:Label>
        <br />
        <a href="#" onclick="show()">Show</a>
    </div>
    </form>
</body>

So this code. might be it'll help you

Hi Duncan,

You can't use ClientID INSIDE external JavaScript file. You have to put it in .ascx or .aspx to work.

HTH.
