Hi All,
[See below for history of posting this question]
In effort to write a loop in ASPX to generate a set of labels, I tried this:
<form id="Form2" method="post" runat="server">
<script language="C#" runat="server">
int nCols = 8;
int nRows = 20;
int iHeight = 25;
int iWidth = 50;
int iVertGap = 5;
int iHorGap = 5;
for (int iRow=0; iRow<nRows; iRow++) // "for"
flagged as an error by the compiler
{
<asp:Label ID="Lbl" RunAt="server" />
[snip]
intending to assign values to the properties of the Lbl object. But the
compiler announced:
CS1519: Invalid token 'for' in class, struct, or interface member
declaration
What can I do to generate a bunch of object programmatically in ASPX?
Thanks in advance,
Richard
I posted this first in microsoft.public.dotnet.framework.
Then thought it would be more appropriate in
microsoft.public.dotnet.framework.windowsforms
Then I received advice that it would be more appropriate in the newsgroups
listed abovel. 8 1590
You cant assign nested controls inline like in asp, you have to ctreate them
at run time add them to the forms collection or to a palceholder.
Label Label1 = New Label()
Label1.ID = "Label"
add it to the form
Form1.Controls.Add(Label1)
or add it to a placeholder
PlaceHolder1.Controls.Add(Label1);
You should create them in form load

unlike asp, only methods, properties and fields are allowed to be defined in
a runat=server script block with asp.net. inline code is only allowed with
the <% %> syntax (which does not allow method declarations).

Dear Jim and Bruce,
Thanks for responding, and thanks for the facts ... though I'm bummed out.
I expected the fact that C# is embedded in ASP.NET would certainly allow for
programmers to escape repetative coding. C'est la vie.

Gentlemen,
I trying to create a matrix of labels on the server, cache the resulting
HTML, and let clients log in and download the generated web page.
Since I can't use "for", how about if I load the text destined for each
page into an Access 2003 or SQL Server 2000 database and executed a foreach
loop to access the text, dynamically create a Label object, assign the
relevant text and compute, then assign, the coordinates?
And I do all this in a PageLoad method?
Thanks in advance for any further consideration,
Richard Muller

Have you read about datagrid or datalist controls. Once you have your data
you can bind this to a list/grid type control and the bind will
automatically create a table for you. Its immensly flexible.

You're not thinking fourth-dimensionally, Richard! ;-)
Actually, you're not thinking object-oriented. In fact, OOP not only allows
for programmers to escape repetitive coding, but allows for much leaner
coding, and easier code maintenance and extensibility. OOP is hard to get
your head around at first, but once you "get it," it all falls neatly into
place, and is actually much easier to work with than procedural programming.
The difficulty in understanding OOP is due to the fact that OOP requires a
much more abstract way of looking at programming. I would strongly recommend
making the effort to get your head around how OOP works. You'll be glad you
did!

Hi John, Have you read about datagrid or datalist controls.
No, I haven't.
I've just started playing with User Controls as a means of encapsulating
some of the code I need.
I just decided/realized that table is a better approach than a matrix of
labels.
I did find the foreach command, so I was heading in the direction of using
an Access DB and sucking in the content for my matrix.
I'll check out datagrid and datalist controls today.
Thanks for the guidance. I needed some high level direction.
Best wishes,
Richard
Hi Kevin,
Thanks for weighing in on my question.
I agree about the value of OOP and have had some experience in C++ business
applications. I'm just trying to get off the ground in this new (for me)
environment. As I said in news:uM***************@TK2MSFTNGP15.phx.gbl, in
response to John Timney's post this morning, I've had a few more thoughts
and will follow his suggestions.
I'm sure with the help of you guys I'll get launched in ASP.NET programming.
Best wishes,
Richard This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
