Using AJAX DropShadow control - can't set Opacity

Just updated to the latest AJAX Toolkit and now no matter what I set the Opacity figure at (0.1 to 1), it is like the default setting is 1 and cannot be changed.  The shadow is simply black.  I need it to be Opacity of .25.  

I updated from a 2010 toolkit version, to the Jan 2013 toolkit.

The issue exists for all my projects, and exists in Firefox, Chrome and IE.

Is this a bug?

Hi,

You need to use AjaxToolKitScriptManager instead of ScriptManager!

Check the sample code -

 <asp:Panel ID="Panel1" runat="server" BackColor="Orange" ForeColor="White">
        Testing 123
    </asp:Panel>

<asp:ToolkitScriptManager runat="server">
</asp:ToolkitScriptManager>

<asp:DropShadowExtender ID="DropShadowExtender1" runat="server" TargetControlID="Panel1" Rounded="true" Opacity=".25">
</asp:DropShadowExtender>

Open in new window


Shadow
Moreover, installing AjaxConrolToolKit from Nuget is easy and safe - http://roopeshreddy.wordpress.com/2012/10/07/installingconfiguring-ajaxcontroltoolkit-through-nuget/

Spot on!  Thanks very much...that helped a great deal.  

In the example I did use ScriptManager instead of the asp:ToolkitScriptManager...but even changing to asp:ToolkitScriptManager didn't change the shadow.  However I used the code sample you attached and it did work...turns out that the shadow will cast normally (be opaque) if you specify the opacity as .25, .5, .75, 1

If you specify .1, .2, .7 etc, then the shadow appears as it would if you entered 1.  

Your answer helped me discover this.  Thankyou.
