I have a gridview which consist checkbox in it.
I have written the following code in my code behind in OnRowDataBound event--

C#

CheckBox control2 = e.Row.FindControl("chk830") as CheckBox;
        if (null != control2)
        {
            bool chkd = control2.Checked;
            if (chkd)
            {
                control2.BorderWidth = 2;
                control2.BorderColor = System.Drawing.Color.Red;
            }
        }

the checkbox has OnClick="chkclick(this)" javascript.

C#

<script type="text/javascript">

    var num1 = "";
    function chkclick(obj) {

       
            if (num1 != "") {
if (document.getElementById(num1).checked ||(document.getElementById(num1).checked==false)) {
                    document.getElementById(num1).checked = false;
                    
              
                    if (document.getElementById(num1.substring(0, num1.indexOf("chkV")) + "chk830").style.BorderColor == "")
                        document.getElementById(num1.substring(0, num1.indexOf("chkV")) + "chk830").checked = false;
      }
    }
   }
  </script>

C#

if (document.getElementById(num1.substring(0, num1.indexOf("chkV")) + "chk830").style.BorderColor == "")

C#

if (document.getElementById(num1.substring(0,num1.indexOf(quot;chkV")) + "chk830").borderColor == "")

Use cssclass for checkbox borders, border colors etc
& check for the classname in javascript as placed in the below code,
i have tested the below code & its working as per your requirement,
verify and comment.

XML

<head runat="server">
    <title>Untitled Page</title>
    <style>
        .TestClass1
        {
            border: 2px solid red;
            padding-top: 4px;
        }
        .TestClass2
        {
            /*
            border: 2px solid black;
            padding-top: 4px;
            */
        }
    </style>
    <script type="text/javascript">

        function chkclick(obj) {
            var num1 = obj.id;
            if (num1 != "") {
                if (document.getElementById(num1).checked || (document.getElementById(num1).checked == false)) {
                    document.getElementById(num1).checked = false;


                    if (document.getElementById(num1.replace("chkV", "chk830")).parentElement.className == "TestClass1") {
                        document.getElementById(num1.replace("chkV", "chk830")).parentElement.className = "TestClass2";
                        document.getElementById(num1.replace("chkV", "chk830")).checked = false;
                    }
                    else {
                        document.getElementById(num1.replace("chkV", "chk830")).parentElement.className = "TestClass1";
                        document.getElementById(num1.replace("chkV", "chk830")).checked = true;
                    }
                }
            }
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:TemplateField >
                    <ItemTemplate>
                        <asp:CheckBox ID="chkV" runat="server" onclick="chkclick(this)" />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField >
                    <ItemTemplate>
                        <asp:CheckBox ID="chk830" runat="server" onclick="chkclick(this)" Checked="true" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

    </div>
    </form>
</body>

Change the OnRowDataBound

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           CheckBox control2 = e.Row.FindControl("chk830") as CheckBox;
           if (null != control2)
           {
               if (control2.Checked)
               {
                   control2.Attributes.Add("class", "TestClass1");
                   //control2.BorderWidth = 2;
                   //control2.BorderColor = System.Drawing.Color.Red;
               }
           }
       }
   }
