Hello Comunity,

i'm using umbraco version 7.1.8 for a week now and I've got a problem.

I'm trying to add a contact control to my contact page and everytime I'm clicking on the send button nothing is going to be send.

The problem is that if I click on the button, the btn_Send method doesnt get invoked.

What i tried?
- aspbutton with onclick
- deactivated all scripts/styles

In Umbraco I've added a macro which is refrenced to the ascx file.
My contactpage has a richtext editor where ive added this macro.

What am I doing wrong? Code below!
Thank you for helping me!

This is my ascx file.

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Kontaktformular.ascx.cs" Inherits="Controls_Kontaktformular" %>
