In the while loop you are not displaying the child node...

<% while (sql("dname") = j)%>
  <% k=1 %>        
          <input type="button" name="b<%=k%>" value="<%= sql("ename")%>">
           <%= sql("ename")% '<-------- added
        <% k=k+1%>    
        <%sql.MoveNext
         wend %>

Also, are dnames and ename are order... your logic works only if they are in order in the database...

There are two ways.
1. load all the records into an array and loop through them to get the child nodes directly.
2. for every dname, query the database again for the childnodes... so there will 2 queries.

I hope I am clear...

This should work. I change your sql statement, added a second sql and removed some extra <% and %>

<% Option Explicit %>
<html>
<head>
<title>view</title>
</head>
<Body bgcolor="white" >
 
 <%
    dim sql,connect,sql2,i,j,k
     set connect=server.createobject("ADODB.Connection")
     
     connect.open "Hd"
     

     set sql= connect.Execute(_
                 "select deptid,dname from dept,emp where dept.deptid=emp.deptid order by dname ")%>
 


 <center><h1>ASP Chart</h1></center>
<br><br>
<table bgcolor="#8FA5AB" color="ghostwhite" border="1" cellpadding="0" cellspacing="0" align="center" width="557">
<tr><td><b><center>DG</center><b></td></tr>
</table>    
<br><br><br>

<form name="f1" action="org.asp">
<center>
<table border="1">
<tr>
<%
if not (sql.eof and rs.bof) then
      do while not sql.eof
            i=1  
            %>
            <td>        
             <b>
                      <input type="button" name="<%=i%>"
            value="<%= sql("dname")%>"></b>
            <%i=i+1%>
            <br><br><br>
            <%
            Dim strSQL="select ename from emp,dept where dept.deptid=" & sql("deptid")
             set sql2= connect.Execute(strSQL)
            if not (sql2.eof and sql2.bof) then
             while not sql2.eof
                     k=1 %>        
                            <input type="button" name="b<%=k%>" value="<%= sql2("ename")%>">
           
                          <% k=k+1    
                         sql2.MoveNext
                     Loop %>

            <br><br><br>
                       &nbsp;&nbsp;&nbsp;&nbsp;      
     
            </td>      
        <%sql.MoveNext

end if
%>
