GroupBox In C#

A GroupBox control is a container control that is used to place Windows Forms child controls in a group. The purpose of a GroupBox is to define user interfaces where we can categorize related controls in a group.

In this article, I will discuss how to create a GroupBox control in Windows Forms at design-time as well as run-time. After that, I will discuss various properties and methods available for the GroupBox control.

Creating a GroupBox

We can create a GroupBox control using a Forms designer at design-time or using the GroupBox class in code at run-time (also known as dynamically).

To create a GroupBox control at design-time, you simply drag and drop a GroupBox control from Toolbox to a Form in Visual Studio. After you drag and drop a GroupBox on a Form, the GroupBox looks like Figure 1. Once a GroupBox is on the Form, you can move it around and resize it using the mouse and set its properties and events.

Creating a GroupBox control at run-time is merely a work of creating an instance of GroupBox class, setting its properties and adding GroupBox class to the Form controls.

First step to create a dynamic GroupBox is to create an instance of GroupBox class. The following code snippet creates a GroupBox control object.

In the next step, you may set properties of a GroupBox control. The following code snippet sets background color, foreground color, Text, Name, and Font properties of a GroupBox.

Once a GroupBox control is ready with its properties, next step is to add the GroupBox control to the Form. To do so, we use Form.Controls.Add method. The following code snippet adds a GroupBox control to the current Form.
