Transparency in WPF

Hi,

I have created a 3D object in WPF using c#. I would like to make them transparent. I tried reducing the alpha value in color palette. Also, I tried to use Opacity property of Brush(Eg: brush.Opacity = 0.25;). Both of them doesn't seem to work. Could some one give some suggestions. Thanks in advance!!!

Well the alpha should take care of this for you. You can look at my article on XAML Series 2. It should some alpha blending. Mostly depends on what is being over laid over what. The example is a silverlight applet that uses what I call a sparkel filter, the filter uses different alpha values to create a star burst pattern in a matrix to give the desired effect.

If you want the whole window to be transparent you need to set the aplha values all the way down the widget hierarchy.

You'd want to draw to a Canvas. A pencil tool would probably best be implemented as a Path. Handle click events and mouse move events to do the drawing.

If the XML isn't well formed, this would be thrown. Are you sure that it is well formed?

Well, I just followed the step on WPF Data Binding Tutorial. There's a xml file that I should make, I just only changes the location of images (add image on image_form). May be I should compare which one of code xml that was true. I'll check it now, can you teach me more.. Sniff | :^)

xaml conditional question

In my xaml page I would like to display an image from my C# project's resources folder depending on the value of binded data. To explain it better, I want to display one of three images (information.png, warning.png, or error.png) depending on what type of data it is. Is there a way to make such a conditional statement strictly in XAML markup language? Thanks.

You would normally do this using a data trigger[^].

Reading Directories on a web server

Hi All,

I get that Silverlight has security on reading directories, and that is fully understandable. What I need to do is read the directories on the web site that the silverlight control is hosted in. This will be hosted on my server, so there is no real risk that I will write code that is going to damage my server. Laugh | :laugh:

I am still new to Silverlight, but not new at all to coding.

I am starting to think that it is impossible to do directly in silverlight. I was thinking that I could write a service that returns the info needed, but that is overkill for what I am doing, and can become a security risk itself.

Please let me know IF I can do it, and how.

Thanks in advance.

Thanks,
Brad

Silverlight apps run on the client so there's no way
they can read anything on the server without making a request
to the server.

A web server like IIS can provide directory browsing, but do you really
want to turn that on? Same implications as implementing your own directory
service...

No, I definitely don't want to do that.

Looks like I will have to create a WCF Service or something so that I can get the info I want.

It just seems like a PITA to go through to get what I want.

Thanks.

Thanks,
Brad

Maybe, but that isn't a Silverlight issue - that's web servers.
If everyone wanted their web directories to be browsable then that
feature would be on by default Smile | :)

AFAIK, DataGrid does not have a rowspan property.

A Grid has a row span and can be set in codebehind as follows

Grid.SetRowSpan();

Anti-aliasing 3D content is not supported on windows XP. You could try changing HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\MaxMultisampleType as described in this article http://msdn.microsoft.com/en-us/library/aa970912.aspx.

I think you may have to create it, there are quite a lot of discussions about it on the web that you can search for. I also came across http://stackoverflow.com/questions/39454/is-there-a-secret-trick-to-force-antialiasing-inside-viewport3d-in-windows-xp where it says it should be HKEY_LOCAL_MACHINE\Software\Microsoft\Avalon.Graphics\MaxMultiplesampleType. Neither of them exist on my vista machine but as they're mainly for debugging I think you create them. They affect all the WPF applications and its recommended your app/installer doesn't change them.
