are your validation controls also under updatepanel? if not, they should be..
and also mention (Page.IsValid) before saving the values 18-Jul-14 5:00am    
yes it is under the panel.

please check your code once again.. below is working
<asp:ScriptManager ID="ScriptManager1" runat="server">

<asp:UpdatePanel ID="UpdatePanel1" runat="server"><ContentTemplate>
      <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:RequiredFieldValidator runat="server" ID="rfvtxt1" ControlToValidate="TextBox1" ErrorMessage="Required"></asp:RequiredFieldValidator>
      <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
      <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

and code behind
protected void Button1_Click(object sender, EventArgs e)
       Label1.Text = "the value is:" + TextBox1.Text; //any code
