How to set the Auto Size Mode of the GroupBox in C#?
In Windows Forms, GroupBox is a container which contains multiple controls in it and the controls are related to each other. Or in other words, GroupBox is a frame display around a group of controls with a suitable optional title. Or a GroupBox is used to categorize the related controls in a group. In GroupBox, you can set a value which indicates how GroupBox behaves when the value of the AutoSize Property is set to true, using AutoSizeMode Property. The value of this property is defined under AutoSizeMode enum and the values are:
- GrowOnly: This value indicates that the GroupVox grow according to the content, but does not shrink if the content is less.
- GrowAndShrink: This value indicates the GroupBox grows and shrink according to the content present in it.
The default value of this property is GrowOnly. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the AutoSizeMode property of the GroupBox as shown in the following steps:
- Step 1: Create a windows form as shown in the below image:
Visual Studio -> File -> New -> Project -> WindowsFormApp
- Step 2: Next, drag and drop the GroupBox control from the toolbox on the form as shown in the below image:
- Step 3: After drag and drop you will go to the properties of the GroupBox and set the AutoSizeMode property of the GroupBox as shown in the below image:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set how GroupBox behave when the AutoSize property set to be true, programmatically with the help of given syntax:
public System.Windows.Forms.AutoSizeMode AutoSizeMode { get; set; }
Here, AutoSizeMode is used to set the value of this property. The following steps show how to set the AutoSizeMode property of the GroupBox dynamically:
- Step 1: Create a GroupBox using the GroupBox() constructor is provided by the GroupBox class.
// Creating a GroupBox GroupBox gbox = new GroupBox();
- Step 2: After creating GroupBox, set the AutoSizeMode property of the GroupBox provided by the GroupBox class.
// Setting Auto Size Mode gbox.AutoSizeMode = AutoSizeMode.GrowAndShrink;
- Step 3: And last add this GroupBox control to the form and also add other controls on the GroupBox using the following statements:
// Adding groupbox in the form this.Controls.Add(gbox); and // Adding this control // to the GroupBox gbox.Controls.Add(c2);
