Michael is right. The control still does have some limitations. When I finish my IronRuby book I'll look at changing some of the implementation. At this moment you would need a create a formatter for ironpython
You can view the RubyFormatter here: http://code.google.com/p/dynamic-script-control/source/browse/trunk/src/DynamicScriptControl/Formatters/RubyFormatter.cs?r=22 Then all that is left to do is to replace the notimplementedexception on the converter http://code.google.com/p/dynamic-script-control/source/browse/trunk/src/DynamicScriptControl/ScriptConverter.cs?r=22 --- Met vriendelijke groeten - Best regards - Salutations Ivan Porto Carrero GSM: +32.486.787.582 Blog: http://flanders.co.nz Twitter: http://twitter.com/casualjim On Tue, Nov 4, 2008 at 12:02 PM, Michael Foord <[EMAIL PROTECTED]>wrote: > Simon Dahlbacka wrote: > >> As the error message says, it cannot find the type LocalTimes. >> >> > > You may be interested in DynamicScriptControl: > > http://www.codeplex.com/dynamicscriptcontrol > > It needs a bit (but not much) work to get it working with IronPython. > > From the project page: > > We created a control that can be used with WPF or Silverlight to integrate > DLR based controls into the xaml so that they can participate a little > better into XAML based applications.. > > > At this moment the control only supports IronRuby but that will soon > change. > > This project on codeplex will only hold releases if you're interested in > the source code or contributing look for us at: > http://code.google.com/p/dynamic-script-control > > I blogged about its usage: > http://flanders.co.nz/2008/06/12/dynamic-script-control/ > > Michael > > Normally you have to map an xml namespace into the corresponding clr >> namespace by adding something along the lines of >> >> xmlns:src="clr-namespace:Whatever.Namespace;assembly=TheAssemblyName" >> >> to the xaml file >> >> and then you would declare the objectDataProvider like this instead >> >> <ObjectDataProvider x:Key="localTimes" ObjectType="{x:Type >> src:LocalTimes}"/> >> >> However, I'm not sure how it works if you don't put LocalTimes in a >> namespace >> >> >> >> >> On Mon, Nov 3, 2008 at 6:08 PM, Dino Viehland <[EMAIL PROTECTED]<mailto: >> [EMAIL PROTECTED]>> wrote: >> >> Declaring an interface from Python is easy: >> >> >> import System >> >> class MyComparer(System.IComparable): >> >> def CompareTo(self, other): >> >> print 'compared' >> >> return -1 >> >> >> a = MyComparer() >> >> b = MyComparer() >> >> c = MyComparer() >> >> l = System.Collections.ArrayList([a,b,c]) >> >> l.Sort() >> >> >> prints: >> >> >> compared >> >> compared >> >> compared >> >> compared >> >> compared >> >> >> Unfortunately I don't know enough about WPF to know why you'd get >> the exception you're seeing.
