I need to capture the value of a label (c #) that has been inserted via Jquery, eg:
<asp:Label runat="server" ID="lblIPLocal" Visible="true"></asp:Label>
//Alimenta a Label
$("[id*=lblIPLocal]").text("teste");
//Porem depois que alimenta a label retorna nulo
string dsUserIP = lblIPLocal.Text;
This is not necessary, you can get the user's IP on the server side without this "artifact".
Just check the Request.UserHostAddress in your code behind :
// Write request information to the file with HTML encoding.
sw.WriteLine(Server.HtmlEncode(Request.RequestType));
sw.WriteLine(Server.HtmlEncode(Request.UserHostAddress));
sw.WriteLine(Server.HtmlEncode(Request.UserHostName));
sw.WriteLine(Server.HtmlEncode(Request.HttpMethod));
