Get value of label changed by jQuery

Question

I have a label in my asp page.

<asp:Label runat="server" style="display: block;" ID="lblRegistrationNo" cssClass="lblUprsregNo"> </asp:Label>

it is populated by a jquery function. but I am unable to get this value on server side.

protected void submit_Click(object sender, EventArgs e)
{
    string regNo = lblRegistrationNo.Text;
}

it always returns an empty string.

Answer 1

Take a HiddenField with label also. And Set Value of hidden Field same as Label. You can Access hiddenField value in back End.
