Create an HTML Radio Button Online

The HTML Radio Button Generator creates an <input type="radio"> together with an associated <label>. Set its group name, submitted value, ID, visible label, and initial checked state; the preview, HTML output, and C# output update together. To build a choice group, create additional radio buttons with the same name, distinct values, and unique IDs.



Create an HTML Radio Button in C#

The C# panel shows how to create the configured radio button and label with Aspose.HTML for .NET . The generated code follows this workflow:

  1. Create an HTMLDocument and use CreateElement() to create an HTMLInputElement .
  2. Set its type, group name, submitted value, ID, and initial checked state from the selected options.
  3. Create an HTMLLabelElement , then set its For property and visible text.
  4. Add both elements with AppendChild() and write the document with Save() .

Configure the radio button first, then copy the updated C# code into your .NET project.


HTML Radio Button Generator FAQ

1. How do I create a group in which only one radio button can be selected?

Create each radio button with the same non-empty name and place the controls in the same form context. Give every button a unique ID and label. Browsers then keep only one option in that group selected.

2. Why would a radio button need a value attribute?

The name identifies the submitted field and groups related radio buttons, while value identifies the selected option. Give every option in a group a distinct value so the server can determine which choice was submitted.

3. What does the Checked option control?

It sets the radio button’s initial selected state. Users can select another button from the same group, and that selection clears the previously selected option.

4. Why should the label’s for attribute match the radio button ID?

Matching values explicitly associate the text with the control. Users can select the radio button by clicking its label, and assistive technologies can determine which text describes the option.

5. When should I use radio buttons instead of checkboxes?

Use a radio-button group when users must choose one option from a set. Use checkboxes when each option can be selected or cleared independently.
