I have a listview (in extended selection mode and synchronized with the current item) and a textbox. The textbox allows the user to input search criteria. On the TextChanged event of the listbox I match the search criteria to the names of listviewitems in the listview and set the selectedindex accordingly. This is to both highlight it an...
Hi! In WPF it's better to create a property "complex" (i.e. of type "Visibility") or a property simple (i.e. of type boolean) and then using a converter to bind the property? The first way is shorter to write, but I don't know what is better about the performances. Thank you! Pileggi ...

I made a very simple test class to show where my problem lies. From the MSDN Documentation, I copied public class TestBox : TextBox { ...
Hello, I'm planning to use thw WebBrowser component to display html that is created on the fly. The perfect choice for this is NavigateToString or NavigateToStream methods.

Using the Visual Studio 2010 tools I have a LINQ-SQL model which acts as the Datacontext for most forms. What I have is a UserControl with a TextBox and Datagrid. The datagrid ItemSource is set upon the UserControl.Loaded event with a ...

However dy default I can drag and drop files on to a WebBrowser control. Further to this it seems I can't disable th...

Hello, In the application I'm building, the user may perform something in one view (backed by a view model) that should trigger an action in one or more other view models. Each of these other vms needs the ability to veto (a.k.a. cancel) the action performed in the first v/vm pair. Example: User clicks on an account in a DataGrid co...

This is a nice-to-have for our designer. She has a layout where a form title, on the top right of the form banner, is two words in English. There are several forms so the words are a little different each time. So the effect is something like: | firstword| | form| There is a fancy swoopy thing underneath this and some other...
I am using the Model-View-ViewModel architecture in a WPF application I am building, and I would like a specific ViewModel to actually be reactive to the size of the view (not a normal use-case of the MVVM approach, I know). Essentially, I have a ScrollViewer object and I want the viewmodel to observe the width and height of the scrollv...

I figure I could check the password on the PasswordChanged event but I can't get the Invalid state to toggle on the boxes. Does anyone have examples of something like th...
