Control array in design time

[Igor]

Can I create control array (like TextBox array) in design mode. In vb6 I
drow some control at the form and then I copy/paste controls. After that
every control have the same name, but they have propetry index which is
position of this control in the array. Can I do this in asp.net or I must
create control array with code?

No, there is no such a thing.

Oh, shit! It means that .NET is not better in every segment than vb6!

They're very different beasts. What are you trying to achieve, perhaps
we could suggest an alternative approach with some more detail.

I make radiobutton array. Then user click on some radiobutton. After that
program must see which of these radiobuttons have property checked=true. but
every radiobutton have property false. Look at this:
Dim rb(0 To 2) As RadioButton
Dim n As Integer

For n = 0 To 2
rb(n) = New RadioButton
rb(n).Text = "Text: " + CStr(n)
rb(n).Groupname ="Group1"
Panel1.Controls .Add(rb(n))
Next
Session("rb") = rb
Than I call this RadioButton array from session to other procedure:

Dim rb(0 To 2) As RadioButton
rb = Session("rb")
Response.Write( rb(0).Checked)
Response.Write( rb(1).Checked)
Response.Write( rb(2).Checked)
Problem is next: Every RadioButton have property Checked=False even when
user check some button. Text property is ok, but checked property is False
every time.

How to fix it?

The controls you restore from the session have nothing to do with the values
you are getting in postbacks. You don't need to use session. Since you
create the radiobuttons dynamically, you need to re-create them on every
postback and then they will pick up the posted values. A good practice is to
re-create the dynamic controls in the Init event.

Here is a good article:

I'm not sure how familiar you are with asp.net, but could this be a
postback/viewstate issue? Where is the first snippet of code called and
where/when is the second bit called? The asp bod's will know, but I'm
guessing your code is being called twice overwriting the checked button
with a new button.
The easy way to check is pop a breakpoint on the first and second bits
of code and see if the first is hit between you checking a button and
the second bit of code being called.

Igor,

You create in fact an array of controls as soon as you put them in a
groupbox, panel or those kind of controls.

Here a little sample how to use it, although that is not about the control
array but more how to use the dynamicly. (Showing desing samples is always
difficult to do).

I hope this helps,
