Using WPF GroupBox in C# and XAML

By default, a GroupBox can have one child only but multiple child controls can be added by placing a container control on a GroupBox such as a Grid or StackPanel.

The GroupBox element in XAML represents a GroupBox control. The following code snippet creates a GroupBox control, sets its background and font. The code also sets the header by using GroupBox.Header.

The output looks like the following windows where a group box is displayed with its content.

The content of a GroupBox can be any content including multiple child controls. If you need to place multiple controls, you may need to use a container control such as a panel or grid.

You can format a GroupBox header’s color and border thickness.

The following code example creates a GroupBox with an orange border with multiple controls.
