我看不出CheckBoxList控制浏览器。可见属性设置为true。
这里,我的ASP代码:<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<br/>
<asp:Label ID="lb2" runat="server" Text="Small Picture:"></asp:Label>
<br/>
<asp:FileUpload ID="fuld1" runat="server" />
<br />
<br/><br/>
<asp:Label ID="lb3" runat="server" Text="Big Picture:"></asp:Label>
<br/>
<asp:FileUpload ID="fuld2" runat="server" />
<br/><br/>
<asp:Label ID="lb4" runat="server" Text="Description:"></asp:Label>
<br/>
<asp:TextBox ID="tb3" runat="server"></asp:TextBox>
<br />
<br />
<asp:DropDownList ID="ddl1" runat="server"
onprerender="ddl1_PreRender">
</asp:DropDownList>
<br/>
<br/>
<asp:DropDownList ID="ddl2" runat="server"
onprerender="ddl2_PreRender">
</asp:DropDownList>
<br/>
<br />
<asp:Label ID="lb5" runat="server" Text="Choose color glasses: "
Font-Size="Large"></asp:Label>
<br/>
<asp:CheckBoxList ID="CheckBoxList1" runat="server" AutoPostBack="True">
</asp:CheckBoxList>
<br/>
<asp:Button ID="btn2" runat="server" Text="Upload" Font-Size="XX-Large"
onclick="btn2_Click" />
