Beginner problem with IF statements

[Karen]

Hi,

I'm just working on my first ASP.net site, and I'm having some problems.
In standard ASP I can easily display output based on whether any content
exists for the database field I'm displaying, but I can't seem to work
out how to do the same thing in ASP.net.

What I'm trying to do is display the content of a Dataset if it doesn't
match a particular value. I have a NavName Dataset, which contains the
name of the section of the site the user is in. If the name of the
section is Home, I don't want the name displayed. In classic ASP I'd
use:

<% if DSNavName.FieldValue("Navname") <> "home" then
response.write "<h1>"
response.write DSNavName.FieldValue("Navname")
response.write "</h1>"
end if %>

But if I try to use a varient on this I get an error message. Do I need
to put this into an "asp:" type block?

Sorry if this seems a really basic question!

This is where the bound controls actually start being really useful. There
are lots of ways to manage the data once you have it in a dataset.

This example show how to split the data based on a condition using something
called a Rowfilter.

Also, using a template column in a bound control like a datagrid allows you
to pass each value through a method (a function) that returns a new or
modified value, thus the example above could be filtered further.

<itemtemplate>
<span><%#
myCustomMethod(Container.DataItem("PersonGender")) %></span>
</itemtemplate>

If you want to do it he old fashioned way, and format the output completely
on your own then you can iterate the dataset using foreach as shown in this
excellent example here
