Add the label inside Update panel Other wise lable does not display any thing
other wise
Eample:
this wrong Only
because the lable field Outside the Update panel so event only fire lable will not display anything

XML

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
   <asp:UpdatePanel ID="testwe"  runat="server">
   <ContentTemplate>
       <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
   </ContentTemplate>
   </asp:UpdatePanel>

C#

protected void Button1_Click(object sender, EventArgs e)
  {
      Label1.Text = "sdjfgdhffd";

  }

This correct One

XML

<asp:UpdatePanel ID="testwe"  runat="server">
   <ContentTemplate>
     <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
       <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
   </ContentTemplate>
   </asp:UpdatePanel>
