Search for rules in HtmlHead.StyleSheet property

[J055]

Hi

I'm adding rules dynamically to the HtmlHead.StyleSheet using the
CreateStyleRule method. I'd like to know how to check whether the rules
already exist first.

Thanks
Andrew

Hi Andrew,

As for the ASP.NET Page.Header.StyleSheet property, I've performed some
research and found that this property is of an internal type, currently we
can only access and manipulate through the two interface
methods(CreateStyleRule and RegisterStyle). And the internal code logical
of "CreateStyleRule" will keep adding the new style rule into an ArrayList
and at runtime, the new rule(added later) will overwrite the former ones. I
think you can make your code logic depend on this behavior. BTW, would you
mind tell us what you'll do that require to inspect the existing rule/style
in the StyleSheet?

Sincerely,

Steven Cheng

Hi Steven

The RegisterStyle method doesn't work for me as it only creates a system
names class selector name. I need to set an ID selector with a width based
on the pages currently visible UserControl. What's happening is that it's
very easy to end up with duplicate entries in the page header style element,
e.g.

#container { width:90%; }
#container { width:600px; }

It would be good if there was a way to check for the #container selector or
even better get the styles for the #container too.

I'm thinking that I may need to manage my own way of adding this to the head
element. Any suggestions would be appreciated.

Thanks
Andrew
