iterate through a set of controls


In VB.net

I have a set of linkButtons controls in a form , which I want to iterate on
them and change their text property.

How it's done ?

Web Forms or Windows Forms?

Dim frm As Control = Me.FindControl( "Form1")
For Each ctl as Control In frm.Controls
if TypeOf ctl Is Linkbutton Then
DirectCast(ctl, Linkbutton).Tex t = "WathEver"
End If

I hope this helps,

You /could/ loop through the Controls collection of the Form,
looking for LinkButtons. Sadly, this /only/ works when all the
LinkButtons are actually placed /on/ the Form and not inside
any "container" controls, like Panels or GroupBoxes, in which
case you have to [recursively] scan the Controls Collection of
each container!

Alternatively, if the LinkButtons are all set up at Design Time,
create a - gasp - Control Array. No, don't laugh; I actually
mean an Array of Controls or, in this case, of LinkButtons, as in

Private AllLinkButtons as LinkButton() = { _
Me.LinkButton1, Me.LinkButton2, Me.LinkButton3

Then, you can simply use

For Each eLB as LinkButton in AllLinkButtons
eLB.Text = "whatever"

Hello, I'd like to iterate through each Page of my ASP.NET project from within a Custom web control and access the Page.Controls collection. I've tried using Reflection on the web project assembly, but the controls collection count was zero. While this method gives details of the private controls in each page, I need access to actual instances of the controls to interrogate their individual properties.

Let's say I rendered a bunch of controls with the same name and different IDs. On postback, can I somehow iterate through these controls (checkboxes in this case, but could be dropdown controls in the future) and get their values and IDs with all this done in the code behind page? A small example would be appreciated. Thanks, Oleg
