Asp.net 如何在vb.net中访问RadioButtonList中的radiobutton

我想在填充

RadioButtonList

时更改RadioButtonList的

CssClass

。我不知道绑定列表时如何访问单选按钮。我是否需要使用

DataBind

或

DataBounding

事件？怎么做

使用该事件，因为此时将填充所有单选按钮

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

    Next

End Sub
