Protected void CloseClick(object sender, RoutedEventArgs e) WindowState = (WindowState = WindowState.Normal) ? WindowState.Maximized : WindowState.Normal Protected void RestoreClick(object sender, RoutedEventArgs e) Protected void MinimizeClick(object sender, RoutedEventArgs e) We add the three click event handlers shown below to take care of this. By extending the default Window class we can use its built-in functionality for minimizing, restoring and closing the window. The class will be public and inherit from the default WPF window class (). The next step is to add a new class called CustomWindow.cs to the project by right-clicking the project name in the solution explorer and choose Add->Class. You add a reference in Visual Studio by choosing “Add reference” from the Project menu or by right-clicking the project in the solution explorer and the required DLLs should be found under the. We also need to add a reference to PresentationCore.dll where the RoutedEventArgs class lives, and WindowsBase.dll. We will need a reference to the PresentationFramework.dll where the out-of-the-box class, which our custom window class will inherit from, is implemented. Start by creating a new C# class library in Visual Studio (File->New Project) and give it a suitable name like Mm.Wpf.Controls.Īfter removing the automatically generated Class1.cs from the project the first thing to do is to add some references. The solution includes two Visual Studio projects, the first one a class library where the control itself is implemented and the second one a sample WPF application which will have a reference to the class library and use the custom window control as its main window.
