WPF Series -9- CustomListBox

When we used ListBox controls in our WPF project we faced the same problem as described in the previous post. Like DataGrid, ListBox control also has a property called SelectedItems, which isn’t a dependency property and therefore not bindable too.

As a result dependency properties of controls get bound to ViewModel properties by specifying bindings in the corresponding View (XAML).

WPF Series -5- Binding ComboBox or ListBox to Enum

Due to these disadvantages we […]

WPF Series -4- MahApps.Metro and MahApps.Metro.Resources

To have a modern look and feel we decided to align our WPF application to Microsoft Metro style. To achieve this, we used the open source toolkit MahApps.Metro. MahApps.Metro is a toolkit for creating Metro / Modern UI styled WPF applications. The MahApps.Metro project was started back in 2011 by Paul Jenkins. The source is available on GitHub (see MahApps.Metro […]

The MVVM patterns intent is to provide a clean separation of concerns between UI and the business logic. It can be used on all XAML platforms. About MVVM Pattern Microsoft describes the motivation for MVVM pattern as follows […]

WPF Series -2- WPF Application Design

Beside the vision and the requirements you also have to have an idea how the WPF application should look like in the end. For that purpose we created a few mock ups during first exchange with the customer in the early stages of the project. In the same stage we also created a process diagram (BPMN) that shows all the […]
