ASP.Net RadioButton visibility inside a RadioButtonList

Under the hood, you can access the attributes of the item and assign it a CSS style.

So you should be able to then programmatically assign it by specifying:

RadioButtonList.Items(1).CssClass.Add("visibility", "hidden")

and get the job done.

Here's how you have to apply a style attribute to a listitem:

RadioButtonList.Items(1).Attributes.Add("style", "display:none")
- OR -
RadioButtonList.Items(1).Attributes.Add("style", "visibility:hidden")

Why not add and remove the radio buttons as needed?

RadioButtonList.Items.Add("Item Name" or index);
RadioButtonList.Items.Remove("Item Name" or index);
