Provide aspx code gridview gvRank because we are not sure what exactly your link is. Secondly provide also code-behind code when a link clicks.

        </div>

Code Behind:

C#

public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                gvRank.DataSource = GetData();
                gvRank.DataBind();
            }
        }

        private DataTable GetData()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Rowid");
            dt.Columns.Add("Name");
            dt.Columns.Add("Marks");
            DataRow dr = null;
            for (int i = 0; i < 5; i++)
            {
                dr = dt.NewRow();
                dr["RowId"] = "RowId" + i;
                dr["Name"] = "Name" + i;
                dr["Marks"] = "Marks" + i;
                dt.Rows.Add(dr);
            }
            return dt;
        }

        protected void gvRank_SelectedIndexChanged(object sender, EventArgs e)
        {
            txtrowid.Text = gvRank.SelectedRow.Cells[1].Text;
            txtname.Text = gvRank.SelectedRow.Cells[2].Text;
            txtmarks.Text = gvRank.SelectedRow.Cells[3].Text;

        }
    }
