Creating a dialog box

A dialog box is a Window that is typically used to get some data from the user, before some operation can proceed. This is sometimes referred to as a modal window (as opposed to modeless, or non-modal). In this recipe, we'll take a look at how to create and manage such a dialog box.

Getting ready

How to do it...

We'll create a dialog box that's invoked from the main window to request some information from the user:

1. Create a new WPF application named CH05.Dialogs.

2. Add a new Window named DetailsDialog.xaml (a DetailsDialog class is created).

3. Visual Studio opens DetailsDialog.xaml. Set some Window properties: FontSize to 16, ResizeMode to NoResize, SizeToContent to Height, and make sure the Width is set to 300:

   ResizeMode="NoResize" SizeToContent="Height" Width="300"
   FontSize="16"

4. Add four rows and two columns to the existing Grid, and add some controls for a simple data entry dialog as follows:

   <Grid.RowDefinitions>
