Thanks. 
 
I am giving it a try. 
BTW, I am extending System.Web.UI.Page class by inheriting it into my custom 
PageBase class. (where I am adding some other custom Sub and Functions) 
 
So I placed into my PageBase your code: 
 
Private Sub PreOrderTraverse(ByVal Parent As Control) 
&nbsp; &nbsp; If TypeOf Parent Is TextBox Then 
&nbsp; &nbsp; &nbsp; ' Do something with CType(Parent, TextBox). 
&nbsp; &nbsp; ElseIf TypeOf Parent Is CheckBox Then 
&nbsp; &nbsp; &nbsp; ' Do something with CType(Parent, CheckBox). 
&nbsp; &nbsp; ElseIf TypeOf Parent Is ListBox Then 
&nbsp; &nbsp; &nbsp; ' Do something with CType(Parent, ListBox). 
&nbsp; &nbsp; End If 
&nbsp; &nbsp; ' Go into children 
&nbsp; &nbsp; For Each c As Control In Parent.Controls 
&nbsp; &nbsp; &nbsp; PreOrderTraverse(c) 
&nbsp; &nbsp; Next 
&nbsp; End Sub 
 
Then on my actual form, in code behind, in Page_load I placed this 
 
PreOrderTraverse(Form1) 
 
It gives an error saying that &nbsp;name Form1 is not declared. 
 
Name of that actual Web page file is Screen3. The HTML view of Screen3 shows Form1 as name of form 
&lt;form id=&quot;Form1&quot; method=&quot;post&quot; runat=&quot;server&quot;&gt; 
all form fields here 
&lt;/form&gt; 
 
Why my code is asking for Form1 to be declared? 
What am I missing? 
 
Thanks

Sorry that i missed your last comment, Form1 is intrinsic so you can add the following code to your page base and call PreOrderTraverse(PageForm): 
 
&nbsp; Private FHtmlForm As HtmlForm 
&nbsp; Protected ReadOnly Property PageForm() As HtmlForm 
&nbsp; &nbsp; Get 
&nbsp; &nbsp; &nbsp; If FHtmlForm Is Nothing Then 
&nbsp; &nbsp; &nbsp; &nbsp; Dim ctrl As Control 
&nbsp; &nbsp; &nbsp; &nbsp; For Each ctrl In Controls 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; If TypeOf ctrl Is HtmlForm Then 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; FHtmlForm = ctrl 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Exit For 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; End If 
&nbsp; &nbsp; &nbsp; &nbsp; Next 
&nbsp; &nbsp; &nbsp; End If 
&nbsp; &nbsp; &nbsp; Return FHtmlForm 
&nbsp; &nbsp; End Get 
&nbsp; End Property 
 
Hope this helps,

<div class="content wysiwyg-content">
I have a simple Web form project (VB.NET, VS 2003). 
 
My Web forms have textboxes, dropdownlists, check boxes, radio buttons web controls. 
 
I would like to do following: 
 
On page load, I would like to automatically detect all Web controls on that page and collect their names and types into an array. 
 
Then I would go through that array and perform some other stuff on each web control based on their types (textbox, checkbox, dropdownlist etc). 
 
Thanks
