DropShadow is an extender which applies a "Drop Shadow" to a Panel. It allows you to specify how wide the shadow is as well as how opaque it is, or if you would like rounded corners.

<ajaxToolkit:DropShadowExtender ID="DropShadowExtender1" runat="server" Opacity="0.50" TargetControlID="Image1" TrackPosition="True" Width="8"/>

Properties of Drop shadow:

TargetControlID - The ID of the button or link for this extender to operate on

Width - The width, in pixels of the drop shadow. Default value is 5.

Opacity - The opacity of the drop shadow, from 0 (fully transparent) to 1.0 (fully opaque). The default value is .5.

TrackPosition - Whether the drop shadow should track the position of the panel it is attached to. Use this if the panel is absolutely positioned or will otherwise move.

Rounded - Set to true to set rounded corners on the target and the shadow. Default is false.

Example:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DropShadow.aspx.cs" Inherits="DropShadow" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<ajaxToolkit:DropShadowExtender ID="DropShadowExtender1" runat="server" Rounded=true Radius=8
Opacity="0.50" TargetControlID="Image1" TrackPosition="True" Width="8">
</ajaxToolkit:DropShadowExtender>
