[thelist] .NET multiple dynamically generated dropDownLists

Inside the loop, you could say something like this:
If Request.Form(ddlCon) = "between" Then
txt.Visible = True
Else
txt.Visible = False
End If
The code below seems like a rather old-school ASP approach to
generating a grid; have you considered a repeater or a datagrid?
Cheers,

Mark,
Do you want this to happen on the client or on postback?
http://groups.yahoo.com/group/AspNetAnyQuestionIsOk/ is another great
place to ask specialized ASP.NET questions like this.
Cheers,
Peter

I am creating a front-end web application that builds a search form to
be filled out by the user to return search results from a web services
application.
Since the number of fields will vary form report to report, I need to
dynamically create the labels, textboxes and dropdownlists.
Here is how I am creating the form:
sub Page_Load(ByVal Sender as Object, ByVal e as EventArgs)
' variables
try
' web service connection code
for each cc in bb.iInList
Dim lbl as New Label()
lbl.ID = "lbl_" & cc.inName.ToString
Dim txt as New TextBox()
txt.ID = "txt_" & cc.inName.ToString
txt.Width = Unit.Pixel(250)
Dim ddlCon as New DropDownList()
ddlCon.ID = "ddlCon_" & cc.inName.ToString
ddlCon.AutoPostBack = true
ddlCon.Width = Unit.Pixel(100)
lbl.Text = cc.inName.ToString & ": "
'build table code (Table1)
next
catch ex As System.Web.Services.Protocols.SoapException
' catch SOAP errors code
end try
end sub
(FYI - this code is drastically trimmed)
What happens is that the table (Table1) is written out like this: this
part is working!
Row
Cell1 = Label (lbl)
Cell2 = Contstructor (ddlCon)
Cell3 = Textbox (txt)
Cell4 = textbox (hidden)
end row
Next row, etc..
I need to be able to target a specific ddlCon - if a user selects
"between" from a ddlCon dropDownList, I need the Cell4 textbox to appear
- but only the Cell4 textbox in that row. Since all the dropDownLists
are dynamically generated, and have dynamically generated Ids, how can I
assign specific events to specific rows?
Any help would be appreciated.
Thanks,
markJ
