placeholder controls -- pulling data

Fubar · September 6th, 2005, 03:50 PM

I've managed to hit a snag here -- trying to pull data BACK from a placeholder control ...num comes from a dropdown list (1-30) and creates a text box, couple labels, couple dropdowns as such

Code:

function makeclientlist(num as integer)

    placeholder.controls.clear()

    dim i as integer

   for i = 1 to num

    dim Label = new Label()
    label.id = "Client" & i
    label.text = "Client : "
    placeholder.controls.add(label)

    dim Box = new textbox()
    box.ID = "clientbox" & i
    placeholder.controls.add(box)

    dim dept = new DropDownList()
    dept.ID = "clientdeptlist" & i
    dept.items.add("Public Safety")
    dept.items.add("Utilities")
    placeholder.controls.add(dept)

    dim div = new DropDownList()
    div.ID = "clientdivlist" & i
    div.items.add("police")
    div.items.add("fire")
    div.items.add("park and recs")
    placeholder.controls.add(div)

    dim endlabel = new label()
    endlabel.id = "endlabel" & i
    endlabel.text = "<br>"
    placeholder.controls.add(endlabel)

   next i

end function

how do I go about drawing that info back ???(for an email actually) I've tried a for each ctrl in placeholder.controls but can't quite get the data a USER enters to come back to something useable.

What is the code you are using, and what is returned as to what is expected?

Code:

function clientbuild() as string

Dim ctrl

    for each ctrl in placeholder.Controls
'call this place1
            clientmessage &= ctrl.gettype.tostring() & "<BR>"

'call this place2
        if ctrl.gettype.tostring() = "System.Web.UI.WebControls.TextBox"

'this works
            dim name as string = ctrl.ID
'this does not pull what the USER has entered, ever.
            dim value as string = ctype(ctrl, textbox).text
            clientmessage &= name & value & "<br>"
        end if
    next

    return clientmessage

end function

place1 returns things like this...
System.Web.UI.WebControls.DropDownList
System.Web.UI.WebControls.DropDownList
System.Web.UI.WebControls.Label
System.Web.UI.WebControls.Label
System.Web.UI.WebControls.TextBox

place2 ONLY returns items defined in the 'population' of placeholder

IE, a user enters in "Joe Bob" for client name, selects "public safety" for the first dropdown and "police" for the second. Click submit on the page which is suppost to grab that info (along with a lot of other stuff, but it works) but leaves them blank or gives whatever I enter in during the makeclientlist function. If I add box.text = "thisneverworks" to the makeclientlist function, it'll catch that and send it ...but never what the user enters

The code you have looks like it should work. I belive the problem may lye in this line:
Dim ctrl

I belive it needs to be:
Dim ctrl as Control

Still nothing. Maybe this'll help -- its the code that should grab the data... for reference, "clientmessage" is a public string thats loaded on pageload as nothing.
[code]
function clientbuild() as string

    Dim ctrl As Control

        for each ctrl in placeholder.Controls

            clientmessage &= ctrl.gettype.tostring() & "<BR>"

        if ctrl.gettype.tostring() = "System.Web.UI.WebControls.DropDownList"
            dim name as string = ctrl.ID
            dim value as string = ctype(ctrl, dropdownlist).selecteditem.value
            clientmessage &= name & value & "<br>"
        end if
    next

    return clientmessage

end function
[/code
if I were to select utilities and fire and click submit, here's the output

System.Web.UI.WebControls.Label
System.Web.UI.WebControls.TextBox
System.Web.UI.WebControls.DropDownList
clientdeptlist1Public Safety
System.Web.UI.WebControls.DropDownList
clientdivlist1police
System.Web.UI.WebControls.Label

which public safety and police are the first two items loaded into those controls. Do I have some kind of order of operation issue or do I need to somehow post those items BACK to the controls first?

I am confused, is the problem with the code you originally posted, or the code you just posted?
