The tools are the most important, without them you couldn't do a single thing.
Surprisingly VS.net 2008 has some great features:
VS 2008 Web Designer and CSS Support
One of the big features that web
developers will quickly discover with
VS 2008 is its dramatically improved
HTML designer, and the rich CSS
support it brings.
VS 2008 now uses the same web designer
that ships with Microsoft's new
Expression Web product. In addition
to providing lots of new
functionality, you'll also find that
this web designer is much faster than
the VS 2005 version (which was based
on a much older code base).
Below is a quick tour of some of the
new web designer features that you'll
be able to take advantage of with both
VS 2008 as well as the free Visual Web
Developer 2008 Express:
Split View Editing In addition to
supporting both source-view and
design-view, VS 2008 adds support for
a new "split-view" mode when working
on pages. This allows you to see both
the HTML source and the Design View at
the same-time, and easily have any
changes you make in one view be
updated in the other:
CSS Style Manager VS 2008 supports a
new tool window inside the IDE called
"Manage Styles". This shows all of
the CSS stylesheets, and their
corresponding rules, for the page you
are currently editing. It can be used
both when you are in design-view, as
well as when you are in source view on
a page:
A circle around a CSS rule in the
manage styles window indicates that
particular rule is in use within the
current document. Using the mouse to
hover over the rule allows you to
quickly see the CSS rule values:
You can then either right-click on a
CSS rule and select "Modify Style" to
bring up a graphical CSS rules editor,
or you can double click on the rule in
the manage styles window to
automatically open the stylesheet file
and jump immediately to the CSS source
definition to edit (with full
intellisense):
For even more tips/tricks about how to
best use the "Manage Styles" tool
window please read this blog post.
CSS Properties Window One of the other
cool new CSS features that is also
supported in both design and source
view is the new CSS Properties Window:
When you select an HTML element or
ASP.NET server control, the CSS
property window will show you all of
the CSS settings currently applied to
it. You can also change any of the
values using the CSS property grid.
The "target rule" drop-down in the
style toolbar allows you to determine
under what rule the settings are
applied (read this blog post to learn
more about the style toolbar and
target rule dropdown).
If, like me, you sometimes struggle
with large CSS stylesheets and find
yourself shouting "why the $!#@ is it
looking like that?", you'll find the
"summary" view of the CSS Properties
window really useful (just click the
summary button at the top of the CSS
properties pane). When you press this
button it enables a filtering mode
that shows you the full inheritance
set of CSS rules for the current HTML
element or ASP.NET control you are
working with:
In the properties grid above you'll
notice that some values are duplicated
multiple times - with red arrows
striking out previous values. This
indicates that a parent CSS rule
setting is being overridden by another
CSS rule's value. You can see both
the original value as well as the
overridden one in the summary view at
the bottom.
You can click on the individual values
to see where in the CSS precedence
hierarchy this value was inherited
from or overridden. In the example
below you can see that the final color
for the current element that my cursor
is on is a dark brown color. If I
select this final color value, the CSS
properties window will draw a blue box
in the applied-rules list above
indicating that this setting is set in
the "singlecontent h3" rule:
If I click on the lighter brown color
setting that this rule overrode (and
which has the red strike-thru), you
can see that it originated with the
page's HTML body CSS rule (notice how
the body rule below is selected in the
applied rules list when I select the
overridden value below):
Please read this dedicated CSS
Properties Window blog post to learn
even more how to use the CSS property
window.
CSS Source View Intellisense The HTML
designer supports the ability to
select an element or control in
design-view, and graphically select a
rule from the CSS list to apply to it.
You'll also find when in source mode
that you now have intellisense support
for specifying CSS class rules:
This is true for both HTML element
(like above), as well as with ASP.NET
server controls:
This CSS intellisense is supported in
both regular HTML / ASP.NET pages, as
well as when working with pages based
on master pages and nested master
pages.
Nested Master Page Support Earlier
this month I wrote a dedicated blog
post that covered the new VS 2008
Nested Master Page Support. All of
the above designer and CSS features
obviously work with that as well:
Summary The above post provides a
quick look at some of the new HTML
designer and CSS tool support in VS
2008 (all of the above features also
ship with the free Visual Web
Developer 2008 Express edition).
Because VS 2008 now has
multi-targeting support you'll be able
to use these feature immediately
without having to install .NET 3.5 on
your servers. You can open existing
ASP.NET 2.0 projects in VS 2008, have
VS 2008 continue to target .NET 2.0 as
the runtime target, and begin using
these features immediately.
Over the next week I'll also be
starting a new multi-part blog series
that covers the new
control that ships as part of ASP.NET
in .NET 3.5. One of the big benefits
of the is that it
enables developers to have total
control over the HTML output emitted
in data scenarios. This works well
with all of the new CSS tool features
above, and enables you to more easily
create great looking web sites and
applications.
Hope this helps,
Scott
