Hiding labels and textboxs in formview templates according to role

[Ann]

I have a formview with templates. I want to hide certain labels or textboxes
according to the user's role membership. I can do this in a sub routine as
long as it's not inside a template, is it possible to do this inside a
formview template?

Some code sample that does not work: (passphrase is the name of the label)

Protected Sub passPhrase_Init(ByVal sender As Object, ByVal e As
System.EventArgs)
If (Roles.IsUserInRole("networkServices")) Then
FormView1.itemtemplate.passphrase.visible = True

Else
FormView1.itemtemplate.passphrase.visible = False
End If
End Sub

Thank you for your time.

Have you added the event handler delegate for the init event?

<asp:Label ID="passPhrase" runat="server" OnInit="passPhrase_Init" />

Yes, I have added the event handler. The problem is it doesn't like my
syntax that I'm using, and I don't know what the correct syntax should be for
the path.

It doesn't like "FormView1.itemtemplate.passphrase.visible"
I get this error: BC30456: 'passphrase' is not a member of
'System.Web.UI.ITemplate'.

I think, it's simple then

Try something like

Protected Sub passPhrase_Init(ByVal sender As Object, ByVal e As
System.EventArgs)

Dim x As Label = CType(sender, Label)
If (Roles.IsUserInRole("networkServices")) Then
x.visible = True
Else
x.visible = False
End If
End Sub

You can also try to use

<asp:Label ... visible=<% #IsAdmin() %>

Public Sub IsAdmin() as Boolean

If (Roles.IsUserInRole("networkServices")) Then
Return True
Else
Return False
End If

End Sub

Public Sub IsAdmin() as Boolean

Public FUNCTION IsAdmin() as Boolean

You have to use the FindControl method on the template. Add a trace="on"
page directive to get a better understanding of the contol nesting on the
page.

Yes, that worked! Thanks

Else

Return True
Else
Return False
End If

Thank you, I'll try this also.

you should be aware that even if a label/textbox whatever is invisible -
when you add data to it it will end up in viewstate. In addition to not showing
the control - it should also not contain data.
