I've been searching for at past few hours with not result to this problem.

Im trying to add a webform user control as a macro to a page.

But all it does when i click the button is refresh the page. It doesnt excute my C#-code.

Page.aspx

<asp:Content ContentPlaceHolderID="cp_content" runat="server">

<form runat="server" ID="frmMain">

<asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager>

<umbraco:Macro Alias="GridLayoutPages" runat="server" />

</form>

</asp:Content>

Callback.ascx

<asp:Panel runat="server" DefaultButton="BtnSendMail" ID="pnlCallback">

    <div class="callback clearfix" id="callbackContainer" runat="server">

        <div style="background-image: url('<%=personImageUrl %>')" class="clearfix">

            <h1>Kom i kontakt med os</h1>

            <div class="col-md-6 call-box clearfix">

                <asp:TextBox runat="server" ID="txbName" placeholder="Indtast navn" />

                <asp:TextBox runat="server" ID="txbPhone" placeholder="Indtast Tlf" />

                <asp:Button runat="server" ID="BtnSendMail" Text="Bliv ringet op" OnClick="SendMail_Click" />

...

            </div>

        </div>

    </div>

</asp:Panel>

Callback.ascx.cs

...

namespace MySupportMergedUserControls

{

    public partial class Callback : UserControl

    {

        ...

        public void SendMail_Click(object sender, EventArgs e)

        {

            Response.Redirect("http://www.google.com");

        }

    }

}

Any help/suggestion is appreciated
