A Radio Button, in the context of programming, is a graphical control element that allows the user to choose only one of a limited number of options. Radio Buttons are usually used in conjunction with a group of other Radio Buttons, all of which have the same name. When one Radio Button in the group is selected, the others become deselected.
Radio Buttons are found in the Forms section of the Visual Basic Toolbox. To add a Radio Button to a form, click on the Radio Button control in the Toolbox and then click on the form. The button will be created and the Properties window will appear.
The Name property is the name that will be given to the Radio Button. The Text property is the text that will be displayed on the button. The Value property is the value that will be assigned to the Radio Button.
There are two ways to programmatically select a Radio Button. The first is to use the Click event. The Click event is fired when the user clicks on the Radio Button. The second is to use the Selected property. The Selected property is a Boolean value that is set to True when the Radio Button is selected and False when the Radio Button is deselected.
The following code illustrates how to use the Selected property.
Private Sub RadioButton1_Selected(ByVal sender As System.Object, _
ByVal e As System.EventArgs)
Console.WriteLine(“RadioButton1 is Selected”)
End Sub
The following code illustrates how to use the Click event.
Private Sub RadioButton1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs)
Console.WriteLine(“RadioButton1 is clicked”)
End Sub

A radio button is a type of control that allows the user to select one option from a group of options. In Visual Basic, you code a radio button by using the RadioButton control.
To create a radio button, you first need to create a form. Then, you add a RadioButton control to the form. You can add as many radio buttons as you want to a form.
To specify the text that appears on the radio button, you set the Text property.
To specify the value that the radio button will have, you set the Value property.
When the user clicks a radio button, the button’s value is sent to the form’s underlying code.
Grouping radio buttons is a way of making it easier for users to select the option they want. In Visual Basic, you can group radio buttons by using the Group property.
To group radio buttons, you first need to create a group. To do this, you can use the GroupName property. This property takes a String value, which is the name of the group. Once you have created a group, you can add radio buttons to it by using the Group property. This property takes a reference to the group that you want to add the radio button to.
Here’s an example. Suppose you want to create a form that allows users to select their favorite color. You can create a group called “Favorite Color” and add three radio buttons to it: Red, Blue, and Green.
When the user clicks on one of the radio buttons, the form will automatically select the corresponding option.
Selecting multiple radio buttons in Visual Basic is a fairly simple process. All you need to do is hold down the Ctrl key while clicking on the buttons you want to select.
This process can be used to select any number of buttons, including all of them.
In Visual Basic, a check box is a type of input control that allows the user to select one or more options from a list. A radio button, on the other hand, allows the user to select only one option from a list.
The main difference between check boxes and radio buttons is that check boxes allow the user to select multiple options, while radio buttons allow the user to select only one option.
Another difference is that check boxes are usually rectangular in shape, while radio buttons are usually circles.
Finally, check boxes are usually used to allow the user to select multiple options, while radio buttons are usually used to allow the user to select a single option.
Radio buttons are a type of input control that allow the user to choose only one option from a group of related options. In Visual Basic .NET, you can add a radio button to a form by using the RadioButton control.
To add a radio button to a form, you first need to create a new project in Visual Studio. Then, add a new Windows Form to the project and design the form by adding controls. After you have added the controls, you can add a radio button to the form by dragging the RadioButton control from the Toolbox onto the form.
When you add a radio button to a form, the RadioButton control will be added to the Form.Controls collection. You can access the RadioButton control in the code by using the Controls collection and the index of the control. The following example shows how to add a click event handler to the RadioButton control.
Private Sub RadioButton1_Click(sender As Object, e As EventArgs)
End Sub
The Click event handler will be executed when the user clicks on the radio button.
You can also set the properties of the RadioButton control in the code. The following example shows how to set the Text and Checked properties of the RadioButton control.
RadioButton1.Text = “RadioButton1”
RadioButton1.Checked = True
How do I code a CheckBox in Visual Basic?
A CheckBox is a control that allows the user to select one or more options from a list. In Visual Basic, a CheckBox is represented by the CheckBox control.
To create a CheckBox in Visual Basic, first create a new project and add a Windows Forms control to the form. Next, double-click the control to open the code editor.
In the code editor, enter the following code:
Private Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs)
End Sub
This code will be executed when the CheckBox is checked or unchecked.
In the code editor, enter the following code:
Private Sub CheckBox1_Click(sender As Object, e As EventArgs)
End Sub
This code will be executed when the user clicks the CheckBox.
Radio buttons are used to select one option from a group of options. In VB.Net, you create a radio button by using the RadioButton control.
Radio buttons are often used in forms to allow the user to select a single option. For example, a form might ask the user’s age. The user might be able to select from a range of ages such as 18-25, 26-35, etc.
To create a radio button, you first need to create a group of radio buttons. You do this by setting the GroupName property of the RadioButton control to the same value for all of the radio buttons in the group.
Next, you need to set the Text property of each radio button in the group. This is the text that will be displayed on the button.
Finally, you need to set the Checked property of each radio button to True if you want the button to be selected by default, or False if you want the button to be unselected by default.
