ASP.NET (C#) Question

C# unable to find content of ASP.net Textboxes

Okay so I am trying to create a sort of registration wizard, so there are different sections within the asp such as the one below:

<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a href="#addwizard" data-parent="#accordion-demo" data-toggle="collapse">
Term Time Address
</a>
</h4>
</div>
<div id="termaddy" class="panel-collapse collapse in" runat="server">
<div class="panel-body">
<form id="form-termaddy" >
<div class="main_input_box">
<div class="col-lg-6">

<div class="form-group">
<asp:TextBox ID="txttermhousenum" runat="server" placeholder="House Number" class="form-control" textmode="SingleLine"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" id="RequiredFieldValidator28" controltovalidate="housenum" errormessage="Required Field" display="Dynamic"/>
</div>

<div class="form-group">
<div class="main_input_box">
<asp:TextBox ID="txtxtermstreet" runat="server" placeholder="Street" class="form-control" textmode="SingleLine"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" id="RequiredFieldValidator29" controltovalidate="street" errormessage="Required Field" display="Dynamic"/>
</div>
</div>

<div class="form-group">
<div class="main_input_box">

<asp:TextBox ID="txtxtermpost" runat="server" placeholder="Postcode" class="form-control" textmode="SingleLine"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" id="RequiredFieldValidator31" controltovalidate="postcode" errormessage="Required Field" display="Dynamic"/>
</div>
</div>


</div>
</div>
</form>
</div> <!--/.panel-body -->
</div> <!-- /#addwizard -->
</div> <!-- /.panel.panel-default -->


So whenever the user fills out the form and hits save. The c# gets the details of the text boxes and updates the db:

//term time address info
string txttermhouse = ((TextBox)termaddy.FindControl("txttermhousenum")).Text;
string txttermstr = ((TextBox)termaddy.FindControl("txtxtermstreet")).Text;
string txttermpostcode = ((TextBox)termaddy.FindControl("txtxtermpost")).Text;

termaddress(txttermhouse, txttermstr, txttermpostcode);


The issue is that when the code passes through this portion it sees each of the text boxes as blank and saves them in the db as and empty string. I have also tried directly referencing the textbox into the method, ie :

termaddress(txttermhousenum.Text, txtxtermstreet.Text, txtxtermpost.Text);


But neither way seems to work. Any help on how to get the text box values would be greatly appreciated, very confused by this issue.

If you are using a master page, make sure that you do not have two <form runat="server"> tags. I've once experienced this issue and it was a result of that.
