Hi, here is the code below:
Note:
1. be sure to add ScriptManager inside form tag.
2. whatever content you want to update put inside <updatepanel><contenttemplate>
3. buttons used inside this updatepanel will cause automatic postback

XML

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

XML

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
          <ContentTemplate>

      <div>
                  <table class="style1">
                              <tr>
                                    <td class="style2">
                                          Enter Your Email</td>
                                    <td>
                                          <asp:textbox id="txtEmail_1" runat="server" style="margin-left: 0px" xmlns:asp="#unknown">
                                                Width="526px"></asp:textbox>
                                    </td>
                              </tr>
                              <tr>
                                    <td class="style2">
                                          <asp:textbox id="txtpass" runat="server" xmlns:asp="#unknown"></asp:textbox></td>
                                    <td>

                              <tr>
                                    <td class="style2">
                                          <asp:button id="Button2" runat="server" text="Cancel" xmlns:asp="#unknown" /></td>
                                    <td>
                                           </td>
                              </tr>
                              <tr>
                                    <td class="style2">
                                           </td>
                                    <td>
                                           </td>
                              </tr>
                        </table>
      </div>
      </ContentTemplate>

          </asp:UpdatePanel>
