After my recent presentation at the VBUG conference, somebody sent me this question: “I have code to style a button and several triggers to change the button’s background color. For some reason, the trigger for the IsPressed property doesn’t seem to work. Why?” Here’s the style code that was being used (this actually includes some changes I made to the original, but never mind that):

<Style TargetType="{x:Type Button}">
  <Setter Property="Background" Value="Red"/>
  <Style.Triggers>

There are several events coming up in the next few weeks, where I’m going to be speaking. Hope to meet some of you there!

If you haven’t considered coming to any of these events, now is the time to do so — there’s lots of stuff going on, and since all of these events happen “off the beaten track”, we hope to see some people there who couldn’t easily make it to the more “standard” event locations in Reading or Dublin. Here’s where I’m going to be: VBUG Spring Conference, Birmingham, UK - April …

Here’s the Fest08 page, and there’s a paragraph on registration right at the top. I’ll be doing a new session there, called Handling data in F#.

Last year this one-day event was great, I’m sure it’s going to be another day full of fantastic content this year. Data today, data tomorrow is the motto this time — a great idea, I think, since almost everybody works with data in some shape or form these days. So, I hope to see you there!

I’m going to be in Galway, Cork and Dublin next week.

In Galway, I’ll do a WPF session for GMIT students on Monday afternoon, and Functional Programming in C# 3.0 in the evening at GAMTUG. If you want to be there, follow this link for all the details! On Tuesday I’m going to be in Cork, delivering a WPF session again. Here’s the link for that one — hope to see you there as well! The video is actually about my WPF introduction, but if there’s enough time, I might well do the longer _WPF in b …

Roughly based on the original concept for the Developer Developer Developer day, both Ireland and Scotland are getting their own DDDs for the first time in 2008. Some slight differences in organization, but great content and speakers nevertheless — see the agendas here for Ireland and here for Scotland. May 3rd (Ireland) and May 10th (Scotland) are the dates, and I’m sure it’s going to be great!

Find the registration page for DDD Ireland here and the one for DDD Scotland here. Hope to see you …

So here they are, the slides and samples of that Functional Programming in C# 3.0 session. My apologies for the slight delay - I already received a few emails about it - but my flight home was cancelled yesterday and everything was a bit chaotic.

Functional Programming in C# 3.0

Have fun!

Thanks to everybody who attended my session at DevWeek! I hope you liked it, I certainly had a lot of fun doing it.

First of all, here’s the download of slides and samples from the session: Functional Programming in C# 3.0

Second, I’ve had a little thought about that example I was asked about during the session. It was one of the methods in the first basic example, and it looks like this:

public static IEnumerable GetAllMemb ...

My talk yesterday at Scottish Developers in Edinburgh went fine — the meeting wasn’t huge, but I had the impression that the topic was interesting to everybody. If you were there, thank you again, and please feel free to contact me if you come up with questions!

Here’s the download of slides and samples from that event: BusinessAppsWithWPFScottishDevs.zip

Update: I noticed that the slides were not in the download — my apologies ab …
