Can you supply the javascript code and possibly the generated markup, so we can let you know where you are going wrong.
If you are using rowspan, you will need to remove the td/cells of the the ones added by the rowspan - hope that makes sense.

try this sample, add jquery reference to it.

code behind:

C#

DataTable dt = new DataTable();
           dt.Columns.Add("id");
           dt.Columns.Add("name");
           dt.Columns.Add("value");
           dt.Rows.Add(1, "priya", "test");
           dt.Rows.Add(1, "vinu", "test");
           dt.Rows.Add(2, "ram", "test");
           dt.Rows.Add(3, "set", "test");
           dt.Rows.Add(3, "set", "test");
           dt.Rows.Add(4, "set", "test");
           GridView1.DataSource = dt;
           GridView1.DataBind();

JavaScript

<script>
        $(function () {
            var clientId = '<%= GridView1.ClientID%>'
            var tds = $('#' + clientId + ' tr ').find('td:nth(0)');
            
            var temp = []; j = 0;
            for (var i = 1; i <= tds.length; i++) {
                debugger;

                var prev = $(tds[i - 1]);
                var curr = $( tds[i]);
                if(j==0)
                temp.push(prev);
                if (prev.text() == curr.text()) {
                    temp.push(curr);
                    j++;
                }
                else {
                    $(temp[0]).attr('rowspan', temp.length );
                    for (var k = 1; k < temp.length; k++) {
                        temp[k].remove();
                    }
                    temp = [];
                    j = 0;
                } 
            } 
        }); 

    </script>
