Now that we’ve got a decent understanding of the common binding properties of a Selector control (I hope! Given the following classes (only class signatures; the full sample project including source code is attached to this post): Note the use of “Mode=One Way” in my Items Source bindings.This indicates to the binding that we’re only going to be updating the binding target (the Combo Box’s Items collection in this case).How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.The following example will show you why we need these two things: Try running it for yourself and watch how even though you add something to the list or change the name of one of the users, nothing in the UI is updated.
To retrieve a collection containing all selected items in a multiple-selection List Box, use the The following code example demonstrates how to use the Selected Index Changed event to search for and select an item in a different List Box control.
A few weeks ago, a friend convinved me to start looking into WPF, XAML and the MVVM pattern. NET Web Forms & MVC2 applications and core system design/development, I haven’t had any exposure to these new(er) technologies, and I thought it might be fun to see what all of the fuss is about. I am using terms in this post in a way which assumes that you are using the MVVM pattern.
Note that the information in this post may also be applied to other controls implementing Items Control. Along the way, I came across a situation where I needed to do some different kinds of binding using Combo Boxes.
The example uses the Selected Index Changed event to determine when the selected item in the List Box is changed.
The example code then reads the text of the item using the , have been added to a form and that both List Box controls contain items that are identical.
