<body>

<div>

复选控件的基本属性都和上一个例子差不多，但是复选空间没有GroupName属性。<br />

<asp:CheckBox ID="cb1" runat="server" Style="position: relative" AutoPostBack="True" OnCheckedChanged="cb1_CheckedChanged" Text="文字具有上划线" />

<br />

<asp:CheckBox ID="cb2" runat="server" Style="position: relative" AutoPostBack="True" OnCheckedChanged="cb2_CheckedChanged" Text="文字具有下划线" /><br />

<br />

<asp:CheckBox ID="cb3" runat="server" Style="position: relative" AutoPostBack="True" OnCheckedChanged="cb3_CheckedChanged" Text="文字具有删除线" />

<br />

<asp:Label ID="Label1" runat="server" Style="position: relative" Text="测试使用的文字"></asp:Label><br />

<br />

注意要将每一个CheckBox都设置为AutoPostBack哦<br />

<br />

下面的类子我们还是使用上面的文字，用CheckBoxList做<br />

<br />

<asp:CheckBoxList ID="CheckBoxList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="CheckBoxList1_SelectedIndexChanged"

Style="position: relative">

<asp:ListItem>文字具有上划线</asp:ListItem>

<asp:ListItem>文字具有下划线</asp:ListItem>

<asp:ListItem>文字具有删除线</asp:ListItem>

</asp:CheckBoxList><br />

<br />

注意要将每一个CheckBoxList设置为AutoPostBack哦</div>

</form>

</body>
