Hi sck10:
The hierarchy of controls with MasterPages looks like this:
Page
- MasterPage
- HtmlForm
- ContentPlaceHolder
- The TextBoxes, etc.
So your logic could look something like the following.
For Each ctlMaster As Control In Page.Controls
If TypeOf ctlMaster Is MasterPage Then
For Each ctlForm As Control In ctlMaster.Controls
If TypeOf ctlForm Is HtmlForm Then
For Each ctlContent As Control In ctlForm.Controls
If TypeOf ctlContent Is ContentPlaceHolder Then
For Each ctlChild As Control In ctlContent.Controls
' Do work...
Next
End If
Next
End If
Next
End If
Next
