# RadioButton Control in C#.Net

## RadioButton Control in C#.Net

The **[RadioButton](https://www.mindstick.com/blog/233/get-checked-radiobutton-using-javascript) controls** are used when we need to make multiple sets of choices available, but we want the user to select only [one of them](https://answers.mindstick.com/qa/47593/what-are-the-prevalent-water-proofing-systems-write-a-short-notes-on-any-one-of-them). If they click on a second selection after making a first, the first [selection is replaced by](https://www.mindstick.com/articles/1103/print-and-print-preview-separately-using-html-css-and-javascript) the second.\

## How to use RadioButton Control

[Drag and drop](https://www.mindstick.com/forum/454/how-to-drag-and-drop-multiple-image-from-one-canvas-to-onther-canvas-in-html5) three RadioButton from the toolbox on the [window Form](https://www.mindstick.com/forum/527/how-to-pass-datagridview-s-cells-value-to-another-window-form).

[Double click](https://www.mindstick.com/forum/156225/differentiate-between-google-adword-and-double-click) on CheckedChanged event.

```
private void radioButton1_CheckedChanged(object sender,  EventArgs e){    //RadioButton1 value will show in Label1 if RadioButton1 is selected   label1.Text ="Selcted Language is  "+ radioButton1.Text;}private void radioButton2_CheckedChanged(object sender,  EventArgs e){    //RadioButton2 value will show in Label1 if RadioButton2 is selected    label1.Text = "Selcted Language is  " + radioButton2.Text;}   private void radioButton3_CheckedChanged(object sender,  EventArgs e) {     //RadioButton3 value will show in Label1 if RadioButton3 is selected    label1.Text = "Selcted Language is  " + radioButton3.Text;  }
```

**Run the project**

When you select any given option then CheckedChanged event will fire and [selected value](https://www.mindstick.com/forum/525/get-selected-value-of-datagridviewcomboboxcolumn) will show in the Label.

**RadioButton [Properties](https://yourviews.mindstick.com/view/81845/now-it-s-possible-to-predict-properties-of-any-molecule):**

Appearance: [Default value](https://www.mindstick.com/forum/23023/default-value-when-using-singleordefault) is Normal. Set the value to Button if you want the RadioButton to be displayed as a Button.

## Example:

```
//set checkbox appearance as buttonprivate void frmRadioButton_Load(object sender,  EventArgs e){       radioButton1.Appearance = Appearance.Button;       radioButton2.Appearance = Appearance.Button;       radioButton3.Appearance = Appearance.Button;}
```

Now RadioButton appearance is as button.

CheckAlign: CheckAlign [property](https://www.mindstick.com/articles/198559/an-ownership-of-property-in-hua-hin) is used to align the check mark in a RadioButton.

BackColor:RadioButton BackColor can be changed through BackColor Properties of RadioButton.

## Example:

```
//Change RadioButton BackColorprivate void frmRadioButton_Load(object sender,  EventArgs e){          radioButton1.BackColor = Color.CadetBlue;       radioButton2.BackColor = Color.CadetBlue;       radioButton3.BackColor = Color.CadetBlue;}
```
