Wpf listview selecteditem not updating Mobile sexchatt site s
The M-V-VM seminar of last month inspired me to finally get serious about WPF.The best way to learn a technology is to write some code with it, so I have begun working on a project of my own, which I hope to complete by end-March (in spite of being working full bore on a project for a client).The following illustration shows a List View with a Grid View view.
This includes properties and templates that are defined for classes that are used in a Grid View view mode, such as Grid View Column and Grid View Column Header. To specify a view that can be used more than one time, use templates or styles.
The first part, Items Source, binds the contents of the List Box to the Observable Collection, by telling it to look for the Persons property in the Data Context (our View Model class).
The second part declares that the data should be displayed calling the Last Name property on the items in the list.
Now let's add the following code to the View Model, to keep track of the selected Person: we want the selected item in the List Box to drive the Selected Person in the View Model.
We could do this by setting the selection through code in the view, working with the Data Context, or firing events.
