Hi,
Is it possible to get a session variable using javascript ? What is the code for that ?
What I want to do is enabling/disabling a listbox depending on the user login id/name/group.
Thanks for your help.

Yes, you can create a Label and then replace it with JavaScript that will create a JavaScript variable containing your session. For example:
Label1.Value = "<script language=""Javascript"">var Mysession = " & Session("UserID") & ";</script>"
(also set Label's "Content" property to HTML)
Now you will have a JavaScript variable "Mysession" that contains your UserID session.

Sessions are accessable at the Server - Javascript in ASP is used at the client.
You can write ASP Server code that can output the Javascript function OR a variable that you can test with your Javascript.

As you have found, the login information is stored in a session variable.
You need to inspect these values and change the Listbox to be disabled based
on these values.
I have written an article showing how you do this. It is available here:

Hi,
Thank you for your helpfull answers.
Peterr : I tried your solution and it works fine. Thanks again.
DonB : I tried your solution too, but I had the following problem :
When I move {LabelDisable} to put it in the <SELECT... > statement, CCS informs me that it can't find the LabelDisable control in HTML and asks me if I want to delete it. If I answer Yes, the custom code BeforeShow is commented, if I answer No, it seems to work, but the listbox isn't disabled...
What am I missing ?

This sounds like the Label was created within a different "template block".
Since CCS processes the template a block at a time, the Label is not seen
where it should be and so the warning appears.
Sometimes the placement of the {xyz} label matters to CCS. I have been able
move it to right before the "> (last item in the html tag) and solve the
problem. I guess CCS fails to properly parse template tags when they appear
as attributes, under certain conditions.
If you repeat the steps, check that there are no <!-- bla bla --> markers
between where you create the label and where you move it to. These indicate
boundaries for the template blocks and you can't move the label across those
boundaries. This can easily happen to you when you are working with a grid
because there are several nested blocks within the grid control.
If you care to post the relevant section of HTML (after creating the label
but before moving it) I'll take a look at it to see what might be wrong with
it.

DonB,
Here is the HTML after I added the label :
<tr>
<td class="SOFA_V4FieldCaptionTD">Avis CD/CS </td>
<td class="SOFA_V4DataTD">
<select name="{AVIS1_Name}" class="SOFA_V4Select">
<option value="" selected></option>
{AVIS1_Options}
</select>
{Label1} </td>
<td class="SOFA_V4FieldCaptionTD"> Motif refus</td>
<td class="SOFA_V4DataTD">
<select class="SOFA_V4Select" name="{MOTIF1_Name}">
<option value="" selected></option>
{MOTIF1_Options}
</select>
</td>
</tr>
Where {AVIS1_Options} is the listbox I am trying to disable.
I tried another handsome solution :
var group;
group=<%=CCGetGroupID()%>; or group=<%=Session("GROUP_SOFA")%>;
But it didn't work... Have you got a clue ?
Thanks again.

I changed the HTML (moved the label):
<tr>
<td class="SOFA_V4FieldCaptionTD">Avis CD/CS </td>
<td class="SOFA_V4DataTD">
<select name="{AVIS1_Name}" class="SOFA_V4Select" {Label1}>
<option value="" selected></option>
{AVIS1_Options}
</select>
</td>
<td class="SOFA_V4FieldCaptionTD"> Motif refus</td>
<td class="SOFA_V4DataTD">
<select class="SOFA_V4Select" name="{MOTIF1_Name}">
<option value="" selected></option>
{MOTIF1_Options}
</select>
</td>
</tr>
This is what I used to test it here. This should work for you. I put a
Before Show event on Label1 and added this code. CCGetUserID() returns "0"
if the user is not logged-in:
If CCGetUserID() = 0 Then
' no session variable, so disable the listbox
Eventcaller.Value = "DISABLED"
Else
' user is logged in, enable the listbox
Eventcaller.Value = ""
End If
On the embedded <%...%>: This will not work because the HTML is read in by
the main ASP page, not executed/interpreted by the web server. So, embedded
script will not be handled as script, just as text.
