I am really having trouble with this. I am trying to call a function from
my .vb file within my .aspx file.
My current results is that nothing happens.
Wondering if someone can help me out.

<form id="form1" runat="server">
<div>
<br />
<asp:Label ID="Label1" runat="server" Text="<%= helloworld()
%>"></asp:Label>
<br />
</div>
</form>

and from my .vb file:


Partial Class _Default
Inherits System.Web.UI.Page

Function helloworld() As String
Return "From.vb"
End Function
End Class

How do I get the label1 to get the text from the helloworld function on
load?

I know I can use "on_load event", but I want to try to call a function like
this just like as if it was databound.

Thanks,

The function must be marked as protected or public in order to be
accessible from the aspx page.

Protected Function helloworld() As String

Hope this helps

Firstly, I think you're making things harder than they need to be...

However, consider this:

Label1 <asp:Label ID="Label1" runat="server"><%=
helloworld()%></asp:Label><br />
Label2 <asp:Label ID="Label2" runat="server" Text="<%# helloworld()%>" /><br
/>
Label3 <asp:Label ID="Label3" runat="server" Text="<%= helloworld()%>" />

Label1 will always work.
Label2 uses databinding syntax, so will work only if you call DataBind() in
before the HTML has been streamed to the client, e.g. in Page_Load
Label3, as it stands, will never work.

There are two ways to bind in .NET. One is declarative, in the tags, as you
are attempting. Note that this can tightly couple your logic very easy.
Follow Alexy's post to help. Mark has also suggested a simpler syntax,
although I don't believe it gets around the issue Alexey mentioned.

The second is to bind in events to controls. It is a much nicer syntax, esp.
with ASP.NET controls. I know you don't want to go this direction, for some
reason, but it is really a better way to handle the issue in almost every
instance.

It doesn't, but that's the artificial restriction that the OP has imposed...

Indeed. As I mentioned, the OP is making things unnecessarily difficult and
complicated...

Thanks #2 worked. That is what I was looking for.

It may look like I am making things difficult, but I am learning asp.net and
javascript and trying to setup some javascript variables and items from
functions.

I dumbed down the example I was looking for ( a lot ) in hopes that it makes
sense to me ( which now I think it does ), and now I can go back and look at
a more complicated example online.

Thanks,

Miro

Good that you know how it works now. Just one remark: in general there
is no need to use the Label control (for client scripting). It can be
also done in the following way

Code-behind

Protected Dim HelloWorld As String = "Hej"

ASPX

.....
<script>
var x = <%=HelloWorld %>
</script>
.....

This would "inject" the value of the HelloWorld variable (it can be a
function too) from ASP.NET

Hope this helps

Don't forget the semi-colon at the end of JavaScript lines... ;-)

....and quotes around the string.

This computer-programming thing needs so many fiddly bits, doesn't it <g>
