I am creating a series of UserControls that all have some similar business logic. So I tried to implement this common business logic in an abstract base class that all of these user controls would inherit from.

However the grid the ScrollViewer is ultimately within doesn’t seem to resize enough to show the scroll bar. I’ve isolated the problem in this sample app, basically some xaml and some code be...
I am trying to bind a property of an element within a UserControl to a property set on the UserControl itself in Silverlight. I'm sure it should be simple, but I haven't managed to get it working with either RelativeSource or ElementName binding. In this example I want the Rectangle to be Green (or whatever the UserControl's Background p...
Had a page that was working fine. Only change I made was to add a datagrid to the page (which also added the xmlns) and all of the sudden I'm getting Page Not Found. Checked the UriMappings. Tried the default nav link. No joy. Ideas? UPDATE: The answer was that I had a mock class that was not initializing a collection. See Byrant's ans...

Ok, I have a Grid which 'auto sizes' to a web browser. In there I have a canvas with shapes drawn onto it. What I want is for the canvas to 'stretch' to fill the page. I tried using a 'Viewbox' from the Silverlight 3 10/09 Toolkit but it does not seem to fill all the space in the grid and only works when I give it an exact pixel count...

Hi. I need to play a custom audio stream in WPF. I can deal with the mp3/wmv restrictions. The MediaStreamSource class seems ideal, but all the examples I have seen are Silverlight 3. Is there a WPF equivalent? Thanks Pete ...
When I see the call System.Windows.Browser.HtmlPage.Window.Eval (which is evil) in ReportErrorToDOM (in App.xaml.cs) this shows me that it has no relationship to onSilverlightError. So what kind of JavaScript-based scenario calls onSilverlightError? When will onSilverlightError definitely be needed? What are Silverlight error-handling co...

But this assumes there is a pre-arranged contract between the host and the DLL. I am looking for a way to display Silverlight content within a running Silverlight application, wi...
Our tests showed that the polling duplex binding simply does not scale and can not be used on a service within a web-farm or even a web garden. We have looked at TCP/IP sockets for a client push method, but the firewall issue is does allow us to use sockets. I was wondering what is the alternative "free" solution to this problem? allowi...
In digital imaging, when overlaying two visual layers there are multiple ways you can calculate the image that results when light from a lower layer shines through an obstructing layer in some way. This can offer effects that do not occur as natural phenomenon, such as multiplying colours. Here's an example of the layer blending mode m...

This is not obvious with smaller text sizes however with the large text size the vertical alignment between the text/content and the dialog image looks ...
