Display variable on asp.net page
I am trying to show text on the webpage if the value of edit = 1 but i get an error:
Name 'edit' is not declared.
with this code:
<% If edit = 1 Then %>
EDIT MODE
<% End If %>
from a previous question, from ImSoLost
Why not do this server side? something like this
dim edit as integer
If Edit = 1 then
label1.text = "whatever you want to say on the page"
Else
label1.text = "Whatever you say for this condition"
End If
Name 'edit' is not declared.

label1.text = "whatever you want to say on the page"

End If
because he will then be limited on formating, he wont be able to dynamically change font styles colours etc and what if his page is dynamically built anyway with no fised label position or size?
you can still change all of that with server side code. It may not be the way he is used to doing it but it can still be done just the same. The question was really directed at crich though.

I get the following error:
Name 'edit' is not declared
with this code:
Sub Page_Load (s as object, e as eventargs)
Dim objChkUsername As String = Session("chkusername")
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub

Dim objChkUsername As String = Session("chkusername")
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub
change it to this
Sub Page_Load (s as object, e as eventargs)
Dim objChkUsername As String = Session("chkusername")
Dim Edit as Integer
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub
Sub Page_Load (s as object, e as eventargs)
Dim objChkUsername As String = Session("chkusername")
Dim Edit as Integer
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub

this is how i am trying to use the edit variable and where the code says the error is:
<% if edit = 0 then %> EDIT <% end if %>
<% if edit = 0 then %> EDIT <% end if %>
ASKER
Sorry - yes i have also tried :
Sub Page_Load (s as object, e as eventargs)
Dim edit as Integer
Dim objChkUsername As String = Session("chkusername")
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub
Sub Page_Load (s as object, e as eventargs)
Dim edit as Integer
Dim objChkUsername As String = Session("chkusername")
If IsDBNull(objChkUsername) Or objChkUsername=" " Then
edit = 0
Else
edit = 1
End If
End Sub

I also tried doing this the server side way you suggest but didn't know how to use the label1.text tag on the webpage without having to put it in a text box.

what is this edit variable used for and where are you setting its value?
ASKER
Ok. The text now appears on the page but doesn't seem to be responding to the conditios that determine whether it should be shown. i have a log out script:
<script runat="server">
Sub Page_Load(s as Object, e as eventArgs)
Dim objChkUsername As String = Session("chkusername")
If Not IsDBNull(objChkUsername) Or objChkUsername<>" " Then
Session("chkusername")= ""
Response.Redirect("index.a spx")
Else
Response.Redirect("index.a spx")
End If
End Sub
</script>
When this is run my session variable should be empty so why does it seem like edit still equals 1??
<script runat="server">
Sub Page_Load(s as Object, e as eventArgs)
Dim objChkUsername As String = Session("chkusername")
If Not IsDBNull(objChkUsername) Or objChkUsername<>" " Then
Session("chkusername")= ""
Response.Redirect("index.a
Else
Response.Redirect("index.a
End If
End Sub
</script>
When this is run my session variable should be empty so why does it seem like edit still equals 1??
if you want to ensure that the session is empty you can do a
session.abandon
Did you hard code Edit = 1 somewhere else?
session.abandon
Did you hard code Edit = 1 somewhere else?
it is prob better code practice to remove the session object then set it to an empty string, you then don't need to declare set or check a second string value, but why are you redirecting to login regardless of the result of the if statement
Sub Page_Load(s as Object, e as eventArgs)
'line below is all on one line
If Not IsNothing(Session("chkuser name")) Then objChkUsername = Session("chkusername") Else Session.Remove("chkusernam e")
Response.Redirect("index.a spx")
End Sub
Sub Page_Load(s as Object, e as eventArgs)
'line below is all on one line
If Not IsNothing(Session("chkuser
Response.Redirect("index.a
End Sub

Thank you for the answers. I split the points as the combination of working through all the possibilites has lead to the right solution.

close to the top you should have something like
<% dim edit as integer or boolean or whatever %>
later in the form you need to assign a value to it
<% if case1 then edit = value else edit = othervalue %>
then again perform a test on it for your text
<% if edit = 1 then %>
some text
<%end if%>
alternatively
<% if edit = 1 then response.wrtie("Some text") %>
