Which radio button is selected c

To programmatically create a radio button, declare a variable of type RadioButton , use the gcnew operator to allocation memory for it and add it to the Controls collection of its parent. Because radio buttons always come as a group, you should include them in another control that visibly shows that the radio buttons belong together. The most common control used for this purpose is the group box created using the GroupBox control.

Unlike most of other controls that can be positioned anywhere, a radio button should not be placed directly on a form. Instead, a radio button should be positioned in a container that belongs to a form. The typical container is the group box. When a radio button is added to a group box, the location of the radio button is relative to its parent.

This location is easy to specify if you are visually designing the application. If you are programmatically creating it, make sure you specify the location based on the control that will hold the radio button. Here are examples:.

To indicate what a radio button represents, it is accompanied by text, also referred to as its caption. To specify the caption of a radio button at a design time, type a string in the Text field of its Properties window.

To programmatically specify the caption of a radio button, assign a string to its Text property. Practical Learning: Introducing Radio Buttons. The application we are going to create is used to calculate the amount owed on a loan using the following formula:. If you add only one radio button to a container, when the application starts, the lone radio button would appear with an empty round circle.

I will try to solve the Problem. View All. Menaka Baskarpillai Updated date Jun 15, C Visual Studio Windows Forms. Next Recommended Reading. In Windows Forms, RadioButton control is used to select a single option among the group of the options.

For example, select your gender from the given list, so you will choose only one option among three options like Male or Female or Transgender. If the value of this property is set to true, then RadioButton is checked and if the value of this property is set to false, then RadioButton is not checked. The default value of this property is false. You can set this property in two different ways: 1. You are allowed to place a RadioButton control anywhere on the windows form according to your need.

Step 3: After drag and drop you will go to the properties of the RadioButton control to set a value which represents the RadioButton control is checked. Output: 2. Run-Time: It is a little bit trickier than the above method.

The following code snippet sets the AutoEllipsis property of a RadioButton to true. Figure 5 shows a RadioButton when AutoEllipsis is true and contents do not fit in the given width of the control.

The Image property of a RadioButton control is used to set the background as an image. The Image property needs an Image object. The Image class has a static method called FromFile that takes an image file name with full path and creates an Image object. You can also align image and text. A typical RadioButton control has two possible states — Checked and Unchecked.

Checked state is when the RadioButton has check mark on and Unchecked is when the RadioButton is not checked. Typically, we use a mouse to check or uncheck a RadioButton.

Usually, we check if a RadioButton is checked or not and decide to take an action on that state something like following code snippet. AutoCheck property represents whether the Checked or CheckState values and the RadioButton's appearance are automatically changed when the RadioButton is clicked. By default this property is true but if set to false.

CheckedChanged event occurs when the value of the Checked property changes. To add this event handler, you go to Events window and double click on CheckedChanged events as you can see in Figure 6. The following code snippet defines and implements these events and their respective event handlers. You can write this code to implement CheckedChanged event dynamically. In this article, we discussed how to create a RadioButton control in Windows Forms at design-time as well as run-time.

After that, we saw how to use various properties and methods.
