如何在vb.net中的RadioButtonList中访问radiobutton

Question

我想在填充CssClass时更改RadioButtonList的RadioButtonList。我不知道在绑定列表时如何访问单选按钮。我需要使用DataBind或DataBounding事件吗？如何 ？

Answer 1

使用DataBound事件，然后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
