Hello,
I have a form page in ASP where the first menu/list function as a filter of
the second menu list. Once I select an item form the first combo I get the
second menu full of options. This is correct. My probem is that the first
combo gets the default value again and I do not see what I did choose.
I do not know if I explained this correctly. Hope someone can understand me.
Thanks a lot, Lina 8 1853
Show the code you're using to populate the first drop down and the code
you're using to retrieve that value.

This is the function code tu fill the combos, wher vector is a variable Pais
filled with a recorset.
Function ComboRS(vector)
'Pinto el combo
for i= 0 to UBound(vector, 2)
Response.Write "<option value='"& vector(0,i) &" - "& vector(1,i)&"'> "&
vector(0,i) &" - "& vector(1,i) & vbCrLf
next
End Function
%>
Here is the call to the recordset and the way I fill the variable Pais:
strPais = "select IdPais, NmPais from Paises order by NmPais"
Call OpenRS(rsPais,s trPais,ConnAxs)
Pais = rsPais.GetRows
Call CloseRS(rsPais)
If request.form("C boPais") = "" Then
CadenaPais = "57"
Else
Izquierda = instr(1,request .form("CboPais" ),"-")
CadenaPAis = Trim(Left(reque st.form("CboPai s"),Izquierd a - 1))
End If
Here is how I work out the first combo:
'<select name="cboPais" size="1" tabindex="10" onChange="submi t();">
'<option selected>-- Seleccione un PaÃ*s --
'<%Call ComboRS(Pais)%>
This is the code for the recorset of the other combo:
strCentral = "select IdProyecto, NmProyecto from Proyectos Where IdPais
='"& CadenaPais &"' AND Tecnologia = '"& TipoPlanta &"' order by NmProyecto"
Call OpenRS(rsCentra l,strCentral,Co nnAxs)
Central = rsCentral.GetRo ws
Call CloseRS(rsCentr al)
I do not get any error message. My problem is tha once I select the first
combo it did filter the second one, but I can't see the data I just selected.
Let's say I select Colombia, and I see it at this pont. But very soon
Colombia is not there, anymore.
Thanks a lot!!!

Try this:
sSelectedCatego ry = Request.Form("c boPais")
Then get rid of the "selected" text in that dropdown box. (<option
selected>-- Seleccione un País --)
Then, add a second argument to your ComboRS function and use it as such:
Function ComboRS(vector, SelectedValue)
'Pinto el combo
for i= 0 to UBound(vector, 2)
Response.Write "<option value='" & vector(0,i) & " - " &
vector(1,i)& "'"
If vector(0,i) = SelectedValue Then REsponse.Write " selected"
Response.Write ">" & vector(0,i) & " - " & vector(1,i) & vbCrLf
next

I follow your instruccions, but I allways get the first combo to display the
first item in the table instead the one I selected.
Do you think I am doing something wrong?
You can see what I am saying by going to this link: http://manager-soft.com/clientes/mic...tml/inicio.htm
and then try the menu "Plantas de Generación" and then "LÃ*neas"

Well, the most important thing is to understand what the goal is. The goal
is to take have the server be aware of the value of the selected item when
it redraws the page after the user selects an item from the first dropdown.
Then, as it loops through those items and is writing out all the <option>
html again, what you want to do in your loop is put in a test to see if the
item that is currently being written is the one that the person selected.
If it is, then add " selected" to the HTML output. Here's a simple example:
<%
Dim i
i = Request.Queryst ring("dropdown" )
%>
<html>
<body>
<form method="get">
<select name="dropdown" onchange="this. form.submit();" >
<%
For j = 1 To 10
Response.Write "<option value=""" & j & """"
If CStr(j) = CStr(i) Then Response.Write " selected"
Response.Write ">" & j & "</option>" & vbCrLf
Next
%>
</form>
</body>
</html>
As far as your page, I don't see any dropdowns. I just see javascript
errors and EOF errors.

Not necessarily. If there's reason to post, post. Then just use
Request.Form instead of Request.QuerySt ring
