Hi all, I've got a button style that I've been developing in WPF, as stated in this question. Another thing I'd like to do with this style is to have the button shrink just a little bit, to make it appear like it's getting clicked as it's getting clicked. Right now, the transform code looks like: <Trigger Property="IsPressed" Value=...
I've adopted what appears to be the standard way of validating textboxes in WPF using the IDataErrorInfo interface and styles as shown below. However, how can I disable the Save button when the page becomes invalid? Is this done somehow through triggers? Default Public ReadOnly Property Item(ByVal propertyName As String) As String Imple...
I have a DVD cataloging application that I wrote a few years ago with MFC. Records are saved in a sqlite database, so basically it's a CRUD app. UI-wise, it has a tree view on the left, a list view (grid) on the top right, and an HTML view (embedded IE) on the bottom right. Nothing fancy. I wanted to update the app with more features, b...

I would like a simple way to ensure that all bindings I've declared in my xaml files go to real properties. Even better, I'd like to instantiate my wpf window in a unit test and call a method to ensure that the bindings are correct. Unfortunately, wpf doesn't even throw an exception if I have something wrong. That leaves me the burden...
How do i bind two TextBox objects to a System.Windows.Size struct? The binding only has to work in this direction: (textBox1.Text + textBox2.Text) => (Size) After a user inserts the width and height in the TextBoxes on the UI the Size object should be created. XAML: <TextBox Name="textBox_Width" Text="{Binding ???}" /> <TextBox Name=...

If I manually resize the width of the ListBox to be less than the ScrollViewer, the MouseWheel works on all of the ScrollViewer but has n...

The Click event on the HyperLink doesn't seem to fire unless CTRL is held-down, so I'm unsure of how to proceed. Thanks for your help, John ...
I am currently developing a WPF client application which uses Linq-to-SQL for the typed table objects and to wrap around an abundance of CRUD stored procedures in a MS SQL database on an external server. I do not foresee manipulating data directly via the context, only the stored procedures. My two biggest concerns are: 1) Database secu...
