Sure, I can help you with that. Here are the steps on how to access radiobutton in radiobuttonlist:

1. Create a new Windows Forms project in VB.NET.
2. Add a RadioButtonList control to the form.
3. In the code behind file, add the following code:

VB.Net

```plaintext
Private Sub RadioButtonList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles RadioButtonList1.SelectedIndexChanged
    ' Get the selected radiobutton.
    Dim radiobutton As RadioButton = RadioButtonList1.SelectedItem

    ' Do something with the radiobutton.
    ' For example, you could print the text of the radiobutton.
    Console.WriteLine(radiobutton.Text)
End Sub
```

1. Run the project. When you select a radiobutton in the RadioButtonList control, the code in the `SelectedIndexChanged` event handler will be executed. The code will get the selected radiobutton and print its text on the console.

Here is an explanation of the code:

- The `SelectedIndexChanged` event is raised when the SelectedIndex property of the RadioButtonList control changes.
- The `SelectedItem` property of the RadioButtonList control returns the selected radiobutton.
- The `Text` property of the RadioButton control returns the text of the radiobutton.

Hi John, \

Use the DataBound event as then all of the Radio Buttons will be populated.

```
Private Sub YourRadioButtonList_DataBound(ByVal sender As
Object, ByVal e As System.EventArgs) Handles YourRadioButtonList.DataBound    For Each rd As RadioButton In YourRadioButtonList.Items        'Or some other condition that determines the CSS Class.        If rd.Checked
Then            rd.CssClass = "NewCssClass"        End If    NextEnd Sub
```
