place this style tag in head part

CSS

<style type="text/css">
      
        .mystyle
        {
            color: Blue;
            background-color: Red;
            border: 2px solid #DCDCDC;
        }
        .nocolor
        {
            background-color: White;
        }
    </style>

place this script in head part

JavaScript

<script type="text/javascript">
       var previousbox = 'TextBox1';
       function changecolor(rid) {

           document.getElementById(rid).className = "mystyle";
           document.getElementById(previousbox).className = "nocolor";
           previousbox = rid;
       }
   </script>

and your design code should like this

ASP.NET

<table width="50%">
                    <tr>
                        <td>
                            <input type="radio" id="Radio1" onclick="changecolor('TextBox1')" name="a" /><asp:TextBox
                                ID="TextBox1" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <input type="radio" id="Radio2" onclick="changecolor('TextBox2')" name="a" /><asp:TextBox
                                ID="TextBox2" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <input type="radio" id="Radio3" onclick="changecolor('TextBox3')" name="a" /><asp:TextBox
                                ID="TextBox3" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <input type="radio" id="Radio4" onclick="changecolor('TextBox4')" name="a" /><asp:TextBox
                                ID="TextBox4" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <input type="radio" id="Radio5" onclick="changecolor('TextBox5')" name="a" /><asp:TextBox
                                ID="TextBox5" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                </table>
