WPF Series -13- Advanced Installer
The last post in this series deals with the packaging of a WPF application. To simplify the installation of our WPF application we decided to package the application as MSI […]
WPF Series -12- Global Exception Logging
During development and debugging of our WPF application some exceptions occurred which were not caught by the code. Such unhandled exceptions are not logged automatically. In order to obtain information about any unhandled exceptions in production and to simplify error analysis, we looked for a way to handle and log unhandled exceptions. After some research we ended up with the […]
WPF Series -11- Custom MetroDialog
After a long break it’s finally time to continue with the WPF series. Today I’ll show you how we implemented a custom metro dialog. Our dialog contains 2 comboboxes and […]
WPF Series -10- InkCanvas with initial StrokeCollection
One of the requirements our WPF project had to meet describes the ability to create a sketch of the sewage shaft for which data is collected. The functional acceptance criteria […]
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. This post shows how ListBox control can be extended with a bindable version of the SelectedItems property. First we have […]
WPF Series -8- CustomDataGrid
According to MVVM pattern the ViewModel interacts with the Model but doesn’t know anything about its View. As a result dependency properties of controls get bound to ViewModel properties by specifying bindings in the corresponding View (XAML). DataGrid control has a property called SelectedItems, which in multi selection mode holds the items that are selected. Unfortunately SelectedItems of DataGrid is […]
WPF Series -7- ViewModel Validation using DataAnnotations
As we often use Data Annotations for basic validation purposes in context of C#/.NET applications (i.e. required, max length, …), we searched for a solution that allows using Data Annotations […]
WPF Series -6- Globalization of Enums
In the previous blog post of this series I wrote about binding ComboBox or ListBox to an enum. Using just the approach described there exposes the enum values directly in […]
WPF Series -5- Binding ComboBox or ListBox to Enum
In our WPF application we wanted to bind ComboBox and ListBox controls to enums. The WPF way to set up such a binding is described here. This solution works absolutely fine but it requires the definition of an ObjectDataProvider for every enum. This in turn leads to lower maintainability and the code is not reusable. 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 […]
WPF Series -3- MVVM Pattern
As mentioned in the previous post of this series the WPF application we implemented follows the MVVM pattern. MVVM stands for Model-View-ViewModel. 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 […]
WPF Series -1- Project Setup
Before starting development we first had to set up a new WPF project. The projects target framework is .NET Framework 4.6.2 and we used Microsoft Visual Studio Community 2015 as […]
WPF Series – Introduction
In the first half of 2017 we implemented a WPF project for one of our customers. The aim of the project was to develop a Surface Pro compatible desktop application for data collection in context of civil engineering. The application allows the user to create, save, edit and export protocols of specific buildings. Furthermore it’s possible to create a PDF […]
Fix Null Reference Exception in XAML Designer
During developing a user control for a WPF UI I encountered a strange null reference exception in the XAML designer. Strange thing was, that when I started the application and switched to the control which contained the user control, everything worked fine. I could’ve just ignored this problem. However since it is very inconvenient writing XAML code without getting a […]
