I'm using an expander inside a Resizer (a ContentControl with a resize gripper), and it expands/collapses properly when the control initially comes up. Once I resize it, the Expander won't properly collapse, as documented below. I ran Snoop on my application, and I don't see any heights set on Expander or its constituents. How would...
Can I programatically set the position of a WPF ListBox's scrollbar? By default, I want it to go in the center. ...
I have been experimenting with WPF and rendering strict XAML markup in a web browser, also known as Loose XAML (explained here and here). It strikes me as mostly useful for displaying static content. However, it also appears possible to bind to an XML data provider. Loose XAML files are not compiled with an application, which create...
I've got a ListBox control and I'm presenting a fixed number of ListBoxItem objects in a grid layout. So I've set my ItemsPanelTemplate to be a Grid. I'm accessing the Grid from code behind to configure the RowDefinitions and ColumnDefinitions. So far it's all working as I expect. I've got some custom IValueConverter implementations fo...
I'm using Console.WriteLine() from a very simple WPF test application, but when I execute the application from the command line, I'm seeing nothing being written to the console. Does anyone know what might be going on here? I can reproduce it by creating a WPF application in VS 2008, and simply adding Console.WriteLine("text") anywhere ...
Has anyone used CSLA in an application that has a WPF front end and a WCF wire for entities? If so, which "entity framework" did you use? (nHibernate, Linq, etc...) What were the hang-ups? What did it help you with? I am concerned with implementing this for an application, not knowing how data-binding, validation with UI/entities, or ...
I tried this XAML: <Slider Width="250" Height="25" Minimum="0" Maximum="1" MouseLeftButtonDown="slider_MouseLeftButtonDown" MouseLeftButtonUp="slider_MouseLeftButtonUp" /> And this C#: private void slider_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { sliderMouseDown = true; } private void slider_MouseLeftButtonUp(obje...
We have a scenario where we want to display a list of items and indicate which is the "current" item (with a little arrow marker or a changed background colour). ItemsControl is no good to us, because we need the context of "SelectedItem". However, we want to move the selection programattically and not allow the user to change it. Is t...

I have a ListBox which until recently was displaying a flat list of items. I was able to use myList.ItemContainerGenerator.ConainerFromItem(thing) to retrieve the ListBoxItem hosting "thing" in the list. This week I've modified the ListBox slightly in that the CollectionViewSource that it binds to for its items has grouping enabled. Now...
I would like to update a Windows Forms application to provide the following features: spell checking limited formatting of text: bold, italics, bulleted lists Ideally the formatted text could be accessed in a plain text way for reporting through tools that don't support the formatting, but could also be rendered as HTML for tools tha...
WPF WebBrowser control looks great but knowledge accumlated over time about WinForms WebBrowser is substantial and it's hard to ignore work like csExWB. It would be nice to know what functional shortcomings or advantages exists in .NET 3.5's WPF WebBrowser control over WinForms WebBrowser control. In particular, is it possible to build c...
The title says it all. All too often I want a WPF slider that behaves like the System.Windows.Forms.TrackBar of old. That is, I want a slider that goes from X to Y but only allows the user to move it in discrete integer positions. How does one do this in WPF since the Value property on the Slider is double? ...
So I've been thinking of going for Microsoft certification and I have to make a choice (for now) between Windows Forms and WPF for developing Windows applications. I have had good exposure to Windows Forms but never tried WPF before. Furthermore, most of the job postings where I live seem to be WinForms-oriented. That might change in the...

I have a simple Person data model: class Person : INotifyPropertyChanged { public string FirstName { get; set; } public string LastName { get; set; } } My binding expression looks like this: <TextBlock Text="{B...
Has anyone found a way to save a FlowDocument as BAML or other compressed format? I can import XML with images to create a new FlowDocument: <TextRange class instance>.Load(fs, DataFormats.Rtf) However, I haven't found a good way to save it in a 'native' compressed format. Uncompressed XAML is easy to generate using: <TextRange cla...

So, I have an autocomplete dropdown with a list of townships. Initially I just had the 20 or so that we had in the database... but recently, we have noticed that some of our data lies in other counties... even other states. So, the answer to that was buy one of those databases with all towns in the US (yes, I know, geocoding is the answe...
