hi,

I have set

protected void Page_Load(object sender, EventArgs e) {

Session["test"] = "sample"; }

 and there is a ASPxButton there, in its client side click event. I want to get this Session's Value

so I set
function(s, e) {
var a = '<%=Session["test"]%>'
alert(a);
}

but the above code did not work in your control client side event. Can you tell me how to get Session's value in your Control client event.

yang, 

you cannot access server session variables on the client, to do that, you will need to use a postback or a callback
