i want to show the table row when the label text changed every time.

i tried too many examples but not get any specific solution.

for example :

<tr>
          <td style="width: 88px">
                </td>
                <td align="right" style="width: 388px">
                    Ports :
                </td>
                <td align="left" style="width: 437px">
                    <asp:UpdatePanel ID="UpGpsPort" runat="server">
                        <ContentTemplate>
                            <asp:Label ID="LblGpsPort" runat="server"></asp:Label>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </td>
                <td style="width: 388px">
                </td>
            </tr>

whenever the LblGpsPort lable value change i want show below table row :

<tr id="TrSim1" style="display: none"  runat="server">
                <td style="width: 88px">
                </td>
                <td align="right" style="width: 388px; font-size: 16px; color: #fcbf04">
                    SIM 1 Details : IMEI :
                </td>
                <td align="left" style="width: 437px; font-size: 16px; color: #fcbf04">
                    <asp:UpdatePanel ID="UpGpsIMEI1" runat="server">
                        <ContentTemplate>
                            <asp:Label ID="LblIMEI1" runat="server" Text=""></asp:Label>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </td>
                <td style="width: 388px">
                </td>
            </tr>

the table row "TrSim1" which i want to enable every time the label value changed
using javascript or jquery anything.
