programmatically modify Panel's CSS properties

09-20-2004

in a code-behind event for a Page , is it possible to obtain a reference to
a Panel's CSS attribute, and then modify the CSS instance's properties ?

Hi John,

The CssClass is just a string that points to the stylesheet class.
Therefore, you can just switch to using a different class at any time. Code
below.

Is that what you meant?

hi John, you can provide the style to your webcontrol by passing a style
sheet through the cssClass property like showcased by ken Cox or you can
set/retrieve style through the CssStyleCollection exposed by the control
like below :

Panel1.Style("background-color") = "blue"
Dim myPanelBackground As String = Panel1.Style("BACKGROUND-COLOR")
Response.Write(myPanelBackground)

This will get included as inline css ofcourse ;p

Also if you are still using the .net 1.0 version to the framework, then if
i'm not mistaken the style property is uppercase. Currently i'm working with
1.1 and this does not seem to be a problem since in my code sample i have
both uppercase and lowercase

background-color
&
BACKGROUND-COLOR

So if the CSSStyleCollection only gets inlines CSS values, how does one read the linked CSS from an external file? R L y d a (t a) G G M I T G (t o d) c o
