Undo/Redo support is one of those golden features that really differentiate a client app from many web apps. There have been a number of methods/techniques to provide this support that I’ve run across from brute force, to the memento pattern , but none that lit any fire for me. Here’s my answer...

Another part of the overall solution we were trying to come up with in conjunction my previous post on Scrolling Multiple Content Areas , we also needed to come up with a way to only show X number of items in the visible region of an ItemsControl wrapped in a ScrollViewer. This was more tricky...

I struggled to solve a UI dilemma while at my current client. For various reasons, we came across a situation in which we needed to scroll two areas of the view based on a single Scrollbar. You can see what we were attempting and finally achieved here . The end result is smooth, yet not quite...

WPF is awesome, but it requires the developer to make a pretty big shift in their thinking of UI. I’ve had a hard time explaining this to people, but last week, I had an opportunity to work through an example with Steve Gentile . That’s the basis of this walkthrough. The Scenerio Steve...

http://dnrtv.com/default.aspx?showID=115 Just awesome! I didn't see anything far fetched other than they must have a great designer on staff. I wonder if the designer was doing the Blend work?

Tonight I presented for the Dayton .Net Developers Group on WPF. Unlike my previous Lap Around WPF @ CONDG which was meant as a beginners guide to WPF, this time we were skipping the basics and plunging into a framework I've dubbed MiniMVC. MiniMVC is, primarily, a set of DependencyProperties and...

It has been quite a New Year so far. As of today, Monday January 14th 2008, I have left Speedway and the Speedy Rewards™ team and found new employment with SDS Consulting and I have new eyes courtesy of Lasik Plus of Dayton . I'd say that's a fairly ambitious first two weeks. I'm still working...

Here's one of those real-world situations that no one bothers to demo. If you are building a form or have some sort of input your gathering from the user, you'll likely want the first input control Focused initially. You have a few ways to do this (in ascending order of recommendation): Call...

This evening the Central Ohio .NET Developers Group was nice enough to let me present on WPF. Everything went fairly well, though it was more a test of my efficiency in WPF development than I had planned; I managed to leave behind the external hard drive that had my code-snippets, slides (both of them...

There are a lot of sites out there with great vector resources provided in Adobe Illustrator files. A few have taken a stab at creating exporters or converts, including Mike Swanson and a CodePlex.com project called XamlXporter . I tried out Mike's XamlExport plugin and it worked fairly well, but...

There is a pretty cool, but curiously quiet, CodePlex project called XamlXporter that allows you to export Adobe Illustrator files/resources to WPF files. This is a great thing since WPF is young and there are a lot of free resources and tutorials for Adobe Illustrator out there, as well as, you will...

I'm working on a WPF app for my wife who coaches our local high school track team. One of the features she wanted was to have some images for different players and teams and, religious debate aside, I have chosen to save these in SQL Server 2005. I'm using NHibernate for all my data access which...

The key to scaling your WPF elements in a specific direction other than down and to the right are the CenterX and CenterY properties of the ScaleTransform . It's easy enough to set these manually, but that's just lazy and asking for long term trouble. Instead, decide how you want it to animate...

One of my play projects with WPF is a photo viewer for the pictures we put out on http://cromwellhaus.com . One of the views is a montage of the latest photos with a random RotateTransform Angle applied to each image's RenderTransform. Getting the view itself set up as cake, but when I attempted...

While up in Redmond for the WPF Bootcamp , we had a short time to work with some of the WPF/E, now Silverlight , team members. At the time Silverlight didn't make a whole lot of sense in our strategy. That said, I hope everyone sees the great potential that comes from some of the features surrounding...

The last few weeks I've felt like a little intern again. With the WPF Bootcamp and the early stages WCF integration into the Speedy Rewards messaging infrastructure (I'll be posting on this soon), I've had lots of time to play with .Net 3.0 stuff. For those that have had a chance to fiddle...

One of the cool tools we had a chance to use while up at the WPF Bootcamp in Redmond was Expression Blend . While there I became pretty engrossed in the ease with which you could create fairly cool animations without an intimate knowledge of Xaml. This made it all that harder to leave seeing as we had...

[Update: These are being posted due to the ftp access restrictions at the Microsoft Campus] Today has been pretty intense which has kept me away from blogging "live". Today started with Kevin Moore , Program Manager for WPF/Blend(?), and a lightning round with Expression Blend . As I mentioned...

To avoid disappointing users after they've gotten as far as running your application on their 1997 300mhz Pentium II, determine their capabilities using the RenderCapability.Tier value before hand and notifying them that they'll need to joing the 21st century before running your app. Henry Hahn...

You may have noticed there were not many blog entries for Day 2. It turns out there's no way to ftp stuff out of the technology center. It's hindering my ability to post with pictures/screen captures. I've got a bunch of posts for you as soon as I figure this out. Stay tuned.

For those who don't already know, I want to make it perfectly clear that I am the last person you would ask to design an appealling interface. Messaging, thread syncronization, etc I'm your guy, but pretty pictures I am not.

We moved past the introductions quickly and are getting down and dirty. Rob Relyea took us through the basics of WPF from the latest Visual Studio Orcas perspective. Starting simple by creating a button via Xaml and a duplicate example using purely C# code. I've posted a copy of the sample here for...

My co-worker Steve and I are here in Redmond this week for a WPF Bootcamp training session. We started off by meeting the WPF Product Unit Manager, Ian Ellison-Tayler, and Lead Program Manager, Rob Relyea. Ian ran through some existing WPF applications floating around the intersphere. As early as it...
