Loop through controls with MaterPage ContentHolder

[sck10]

I changed my aspx page to use a master page. The problem is that I can no
longer loop through the controls on the content page. My question is how do
you loop through the controls on the master page and how do you loop through
the controls on the content page when the content is inside the ContentHolder
control?

Below is an example of the control loop before using a master page.

Sub FindControlsInW ebForm()
Dim strValue As String = ""

'Loop through controls
For Each ctlPage As Control In Page.Controls
If TypeOf ctlPage Is HtmlForm Then
For Each ctlChild As Control In ctlPage.Control s
If TypeOf ctlChild Is Label Then strValue &= "Page.Label .ID = " &
ctlChild.ID & ".ID<br>"

'Panel
If TypeOf ctlChild Is Panel Then
strValue = "Panel.ID = " & ctlChild.ID & ".ID<br>"

For Each ctlGrndChild As Control In ctlChild.Contro ls
If TypeOf ctlGrndChild Is TextBox Then strValue &=
"Panel.TextBox. ID = " & ctlGrndChild.ID & ".ID<br>"
Next ctlGrndChild
End If
Next ctlChild
End If
Next ctlPage
End Sub

Thanks in advance,

Hi sck10:

The hierarchy of controls with MasterPages looks like this:

Page
- MasterPage
- HtmlForm
- ContentPlaceHol der
- 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.Contr ols
If TypeOf ctlForm Is HtmlForm Then
For Each ctlContent As Control In ctlForm.Control s
If TypeOf ctlContent Is ContentPlaceHol der Then
For Each ctlChild As Control In ctlContent.Cont rols
' Do work...
Next
End If
Next
End If
Next
End If
Next
