小弟遇到一个RadioButtonList中文字样式的问题。

aspx代码：

C# code

<asp:RadioButtonList ID="rblEnergyType" runat="server" CssClass="txtSelector" RepeatDirection="Horizontal" RepeatLayout="Flow"></asp:RadioButtonList>

C# code

rblEnergyType.DataSource = DataTable;rblEnergyType.DataValueField = "ID";rblEnergyType.DataTextField = "NAME";rblEnergyType.DataBind();

HTML code

<span id="rblEnergyType" class="txtSelector"><input id="rblEnergyType_0" type="radio" name="rblEnergyType" value="0" checked="checked" /><label for="rblEnergyType_0">全部</label><input id="rblEnergyType_1" type="radio" name="rblEnergyType" value="1" /><label for="rblEnergyType_1">电</label><input id="rblEnergyType_2" type="radio" name="rblEnergyType" value="2" /><label for="rblEnergyType_2">水</label><input id="rblEnergyType_3" type="radio" name="rblEnergyType" value="3" /><label for="rblEnergyType_3">气</label></span>
