aspx thread: Pagelet (.ascx) problems
Message #1 by "Kevin James" <kjames45@h...> on Tue, 8 May 2001 13:29:53

I'm having a problem setting properties within a pagelet file. My calling
script has the following:
<%@ Register TagPrefix="BI" TagName="LoginPage"
src="Include/BI_LoginPage.ascx" %>
<BI:LoginPage id="loginPage" AddHeader="True" AddFooter="True"
Framed="Yes" runat="server" />
And then the pagelet file has the following code:
<script language="VB" runat="server">
Private header As Boolean
Private footer As Boolean
Private frames As Boolean
Public Property AddHeader As Boolean
Get
If header then
AddHeader = "True"
Else
AddHeader = "False"
End if
End Get
Set
If (String.Compare(AddHeader,"True",true) = 0) then
header = true
Else if (String.Compare(AddHeader,"Yes",true) = 0) then
header = true
Else
header = false
End if
End Set
End Property
Public Property AddFooter As String
Get
If footer then
AddFooter = "True"
Else
AddFooter = "False"
End if
End Get
Set
If (String.Compare(AddFooter,"True",true) = 0) then
footer = true
Else if (String.Compare(AddFooter,"Yes",true) = 0) then
footer = true
Else
footer = false
End if
End Set
End Property
Public Property Framed As String
Get
If frames then
Framed = "True"
Else
Framed = "False"
End if
End Get
Set
If (String.Compare(Framed.ToString,"True",true) = 0) then
frames = true
Else if (String.Compare(Framed.ToString,"Yes",true) = 0) then
frames = true
Else
frames = false
End if
End Set
End Property
</script>
The values being passed to the Set statements are ALWAYS "True" or "False"
though, no matter what I put in the string calling it, and putting "True"
does not necessarly mean that it will pass "True", it's just as likely, if
not more likely, to pass "False" in that case.
Am I calling this wrong? Some change in VB that I've forgotten?!
Thanks in advance,
Kevin

I'm not sure what your problem is exactly, but I did see one problem with
your code. If you think I am wrong I probably am since my .Net experience
is mostly with C#.
In the Property GETs you should return the value using
Return <value>
Rather than
Property = <value>
For Example:
Public Property AddHeader As Boolean
Get
If header then
AddHeader = "True"
Else
AddHeader = "False"
End if
End Get
Set
If (String.Compare(AddHeader,"True",true) = 0) then
header = true
Else if (String.Compare(AddHeader,"Yes",true) = 0) then
header = true
Else
header = false
End if
End Set
End Property
Should Be:
Public Property AddHeader As Boolean
Get
If header then
Return "True"
Else
Return "False"
End if
End Get
Set
If (String.Compare(AddHeader,"True",true) = 0) then
header = true
Else if (String.Compare(AddHeader,"Yes",true) = 0) then
header = true
Else
header = false
End if
End Set
End Property
Using the syntax that you are, you are assigning the value to the property
rather than returning it to the calling code. And since you are not
returning any value, it always shows up as false.
Please let me know if I am wrong.

Nope, there's no return in VB as far as I know. Unless that's changed in
VB.NET. Normally you just assign the value to the property name (or
function name if you're using a function) and it automatically gets
returned.

Yes. i think this is one of the changes in .Net. I am familiar with VB 6
and I know what you mean. Try it and let me know

It may be, but that's actually beside the point because I don't really
need to GET the values. What I need to be able to do is SET them with the
<BI:LoginPage > call.
According to the Preview of ASP+ the code there should do that, but I
guess the difference between the example in the book and my code is that
I'm trying to set variables as opposed to values in a web control.
However, I know the code is running, because if I put something like
header = true after the if statement, the header will be set to true, but
the value being passed to the pagelet is always "False" not whatever I put
in the AddHeader="value" attribute of the <BI:LoginPage > call.

Just to let others know since I finally figured this out:
When you're trying to set a property in VB using the code below, ASP.NET
passes the value for the attribute in a variable called (surprisingly)
Value. So what I should have been doing is the following:
Public Property AddHeader As String
Get
If header then
Return "True"
Else
Return "False"
End if
End Get
Set
If (String.Compare(Value,"True",true) = 0) Then
header = true
Else if (String.Compare(Value,"Yes",true) = 0) Then
header = true
Else
header = false
End if
End Set
End Property
