I have given you one approach to reach your goal the rest of milestone you need to travel alone :)

XML

<script>
        function changePrevRowColor(elem) {
            //document.getElementById(elem).style.backgroundColor= "white";
            var lastIndex = elem.lastIndexOf("_");
            var lastsubstringIndex = (elem.substring(lastIndex + 1, elem.length)) - 1;
            if (lastsubstringIndex < 0) {lastsubstringIndex = 0; }
            document.getElementById(elem.substring(0, lastIndex) + "_" + lastsubstringIndex).style.backgroundColor = '#FFCCCC';
        }
    </script>

LISTVIEW:

XML

<asp:ListView ID="lstTest" runat="server" ClientIDMode="Predictable" >
            <ItemTemplate>
                <asp:Label ID="lblRowId" runat="server" Text='<%#Bind("col1") %>' onclick="javascript:(changePrevRowColor(this.id));"></asp:Label>
            </ItemTemplate>
        </asp:ListView>
