Call function in codebehind from jscript in aspx page

[moondaddy]

I'm using vb.net and have an aspx page where I want to call a function in
the code behind to do something on the backend and I want to call this
function from a jscript function in the aspx page. Furthermore I know there
will be a postback involved but the state of the page will not change at all
so I would like it to be as efficient as possible with no appearance to the
user that anything happened.

I saw in someone else's code where they achieved this by clicking on a <a>
tag that had an href attribute in it like this:
<a title="Add To Shopping Cart" href="<%#
HRefForSKU(Data Binder.Eval(Con tainer.DataItem , "SKU1"))%>" >

however in my case I don't want to put the href attribute in the <a> element
because it puts a line under all the text which we don't want. Instead I
was going to put in a onclick event that would pass a parameter to a jscript
function that would then try to do the same thing as the href attribute
above.

Any ideas?

Hi Moondaddy,

There are a few ways I've turned up that will allow you to do this:

1) Call __doPostBack explicitly to fire server side events.
2) Use a hidden form field to hold function information and then call a
function on the server based upon the value of that form field.

The final method is the best choice (only choice really) if you don't want
to cause a postback when the server-side function is called. It involves
using the WebService behavior and calling it from DHTML.
