Make a button as template field

C#

<asp:templatefield xmlns:asp="#unknown">
                 <itemtemplate>
                 <asp:linkbutton id="lb1" runat="server" causesvalidation="false" onclientclick="return <b>confirm('Are You sure to delete this entry')</b>" text="Delete">CommandArgument='<%#Eval("id")%>' ></asp:linkbutton>
                 </itemtemplate>
                 
                 </asp:templatefield>

and on row command event of gridview use as

C#

  protected void rowcmd(object sender, GridViewCommandEventArgs e)
    {
    
        try
        {
           
            Int32 id = Convert.ToInt32(e.CommandArgument);
            string comm = "Delete from tblComments where id=@id";
            SqlCommand cmd = new SqlCommand(comm, Db.GetConnection());
            cmd.Parameters.AddWithValue("id", id);
            cmd.ExecuteNonQuery();
             GridView1.DataBind();
        }
        catch (Exception ex)
        {
        }

    }
}
