Referencing textbox

[Morten Snedker]

Im trying to set value of a textbox, but it fails.

txtBox.Text = obj.Effekt does nothing on the page, but the last one
does.

Fieldname is positively correct.

What am I doing wrong?

Dim listNr As String = Right(ListName, 1)
Dim FieldName As String = "txt5" & listNr & "_effekt"

Dim txtBox As New TextBox
txtBox.ID = FieldName

Dim obj As Naturgas
obj = CType(_naturgasList(idx), Naturgas)

txtBox.Text = obj.Effekt
Me.txt51_effekt.Text = obj.Effekt

You create a brand new TextBox, but you don't add it to the Page. It's
just an object which will be deleted as soon as the Page is recycled
(when the Response is sent).

HTH,

You are never adding the txtBox to the page...you need a placeholder or some
other container on the page..
myPlaceholder.Controls.Add(txtBox);

Thanks to the both of you. It seems I haven't explained myself
properly:

I have txt51_effekt, txt52_effekt..txt55_effekt

What I'm trying to do is to reference these dynamically, not creating
new ones. So I guess I got it all wrong. :-\

So, how do I reference each of them dynamically?

TextBox txt = Page.FindControl(string.Format("txt{0}_effket", _someId)) as
TextBox;
if (txt == null)
{
//something bad happened
}

Careful to translate that to VB.NET before compiling, though ;-)
