Object with all of form's controls to loop through ASP.NET

[David A. Beck]

Is there a way I can loop through a form object in ASP.NET codebehind like
in VB.NET and get all of the controls?

[Chris Bower]

Use the Controls collection.

dim ctrl as Control
for each ctrl in Page.Controls
.....
next

You can loop through the controls collection.
However it gets complicated if you have controls nested within other
container controls.
Here's some code Kevin Spencer posted a while back that provides a good
demonstration using recursion.

Private Function FindChildContro l(ByVal objSearchContro l As
System.Web.UI.C ontrol, _
ByVal strControlID As String) As Object

Dim objChildControl As System.Web.UI.C ontrol
Dim objControl As System.Web.UI.C ontrol

If objSearchContro l.Controls.Coun t = 0 Return Nothing

For Each objChildControl in objSearchContro l.Controls
objControl = FindChildContro l(objChildContr ol, strControlID)
If Not IsNothing(objCo ntrol) Return objControl
Next

Return Nothing
End Function

Steve:

Thanks. This code searches for a given control name in a control that itself
has controls. I have not been sucessful yet in adapting it to loop through
the Page.Controls object for my "Form1" to get all the controls.
