By default, the RadioButtonList Web server control displays a single column of buttons. However, you can specify any number of columns, and within the columns, you can specify how the items are ordered: vertically (the default) or horizontally. Vertical layout in three columns results in a layout such as the following:

A D G B E H C F

Horizontal layout for the same items results in the following layout:

A B C D E F G H

Note
If you are working with individual RadioButton Web server controls, you do not set layout as a property of the control. Instead, you set it by simply adding the radio buttons within the page flow. For details about the differences between these controls, see RadioButton and RadioButtonList Web Server Controls Overview.

To specify column count and ordering

Set the RadioButtonList control's RepeatColumns property to the number of columns you want.

Set the RepeatDirection property to Vertical or Horizontal using the RepeatDirection enumeration, as shown in the following code example.

Protected Sub Button1_Click(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Button1.Click ' Create five radio buttons. Dim colors() As String = _ New String() {"Red", "Blue", "Green", "Yellow", "Orange"} RadioButtonList1.Items.Clear() Dim i As Integer For i = 0 To ubound(colors) RadioButtonList1.Items.Add(colors(i)) Next ' Lay out the radio buttons horizontally. RadioButtonList1.RepeatDirection = RepeatDirection.Horizontal End Sub

   RadioButtonList1.Items.Clear()
   Dim i As Integer
   For i = 0 To ubound(colors)
      RadioButtonList1.Items.Add(colors(i))
   Next
   ' Lay out the radio buttons horizontally.
   RadioButtonList1.RepeatDirection = RepeatDirection.Horizontal
End Sub

   this.RadioButtonList1.Items.Clear();
   for(int i=0;i < colors.GetLength(0);i++){
      this.RadioButtonList1.Items.Add(colors[i]);
   }   
   // Lay out the radio buttons horizontally.
   this.RadioButtonList1.RepeatDirection = 
       RepeatDirection.Horizontal;
}
