How about creating a cookie using javascript and then picking this up using
your code behind?

Hi,

That's good idea, but I don't want to have cookies behind my code... I
read somewhere that it can be done with RegisterHiddenField. I create a
hiddenfield even change value, but then how I read hidden field back to my
variable in asp.net program... Examples about it are not too perfect in MS
documentation.

Anton, ml.

Hello Anton,

I believe you have to something like this:

var elMyElement = document.getElementByID("ElementName");

elMyElement.innerHTML = "your text here";

<form id="frmMain" method="post" runat="server">
<asp:Label ID="lbl" Runat="server"></asp:Label>
</form>


private void Page_Load(object sender, System.EventArgs e)
{
this.RegisterStartupScript("initLabel", "<script>document.all['" +
lbl.ClientID + "'].innerText='some value';</script>");
}

A label with the id "myLabel" renders as a span if the page uses master
pages the id will be changed, it will have a prefix starting with ctl00. you
need to find that Id in the source and then use it in your JavaScript to
change the spans innerText or innerHTML

to get the client id of the server control you can also use
<%=myLabel.clientId%>
