Get label value on server side set by JavaScript in ASP.Net

Hi everyone,

I have a asp label with this content: <asp:Label ID="lbl_curso" Text="old text" runat="server" Visible="true"></asp:Label>

I´m changing label text by javascript code: $("#lbl_curso").html("new text from javascript");

But, when I tried to read the label text value using C# code, the content showed is "old text". var text_content = lbl_cursoText;

Please, how can I update label content when I updated by javascript code? (to read from C# code)

Thanks, best

Daniel
