Passing data from server side to client side?

[Mike Fellows]

Ok, im not sure if this is at all possible and if it is how i go about it is
beyond me

i have a piece of client side code that requires a piece of data from the
server side (an ID number in this case)

how can i pass the data from one side to the other, or retrieve it from the
webform on the client side?

i hope ive explained this properly

Mike,

This is one of the most common tasks in ASP.NET development. The solution is
to use hidden elements. If you need a single id value, you can use any html
element capable of holding values. If you need to pass the value back, you
need to use a <input type="hidden" ...>. If you need an id column in a grid,
you need to ad a column to your datagrid and make it invisible with a
stylesheet rule.

Note, if you use a server control and set property Visible to false, the
control won't be rendered to the client and you won't get anything.

That's fine. Give you label an id and refer to it from javascript. If it is
an asp:Label, it will translate to <span> and you can get the label text via
innerText property.

Mike,

Let's say you want to pass hidden id value from server to client.

1. Add a hidden label control to the aspx page:
<asp:Label id="hiddenId" runat="server" CssClass="Hidde n"></asp:Label>
Add a stylesheet rule for Hidden to the page: .Hidden{display :none}

2. In the code-behind on server-side assign values to the id:
hiddenId.Text = "12345";

3. In javascripts on client-side get the value:
var id=hiddenId.inn erText;

If it is not clear, please tell me what step causes a problem.

Mike,

A few things:

You can't have webcontrols outside <form> tags.

The javascript should be a function and you should call it on client-side
load event:
<SCRIPT language="javas cript">
var id;
function getId() {id=hiddenId.in nerText;}
</SCRIPT>
....
<body MS_POSITIONING= "GridLayout " onload="getId() ">
After this variable id is available to other javascripts functions on the
page.

Also the stylesheet rule for Hidden is missing, unless you don't want to
hide the id.
