DropShadowExtender (demo)

DropShadow is an extender that applies drop shadow to an ASP.NET Panel control.

Properties

Name	Description
Opacity	The opacity of the shadow, from 0 (transparent - no shadow rendered) to 1.0, which is fully opaque black. Remarks: The default is .5.
Radius	Specifies the radius of rounded corners in pixels.
Rounded	A Boolean value that specifies whether or not corners of the target and drop shadow should be rounded.
TrackPosition	Determines whether or not the DropShadow tracks position or size changes of the panel it is targeting. Remarks: This is false by default. If true, DropShadowBehavior uses a timer to poll for the position of its target, so don't turn it on unless it's needed.
Width	The shadow width on each side in pixels. Remarks: The default is 5.

Client methods

setShadow(force, norecurse)

Draws shadow around the control.

This function does most part of work when positioning and sizing the shadow. It caches values to avoid extra work. It's called on a timer so we need to keep its weight light. Params:

• force

  • Type: Boolean
  • Description: Whether to force the bounds change.

• norecurse

  • Type: Boolean
  • Description: Whether to recurse if we need to recreate the shadow div
