Applying styles from multiple sources

[DalePres]

Is there a way to determine the order or priority of applying styles in a
custom web control? For example, I have a control with default style
settings for many features, and exposed public properties to change those
settings as well. It is easy enough to set the value of the public property
to the default, then use the public property to render my control.

Where it becomes more confusing is when applying style sheets. If a
developer uses my control and applies a style sheet, I have no way of
knowing which style parameters he has applied in the style sheet. Therefore
I don't know which default styles to leave out of my rendering.

So the bottom line is, I think, how to prioritize and apply styles from
default styles, public property styles, and css class styles.

Thanks,

Dale

Second try here... Microsoft, Where're those 48 hour responses advertised in
my MSDN subscription?

(I'm not microsoft, and am asking questions too - so don't expect too
much!).

Dale - I rather think that what happens will happen exactly as if all the
style elements had been included in the resulting html. In fact that may be
exactly how it works. Of course the style parse may well ignore overriden
elements, but it won't know which they are for elements in style sheets
defined outside .net.

So in short I wouldn't worry about it. Any specific style="" in an element
should override higher elements.

Accordingly you should look at the style prioritisation rules.

There's a little bit on this in 'Dynamic HTML' by Danny GOodman and no doubt
an incomprehensible standard at W3C somewhere.

Styles trickle down.

or
think bottom-up.

an embedded style overrides an inline style,
which in turn overrides linked stylesheets.

hope this helps

Thanks all for your advice on this one.
