DropDownList 问题

Question

用Html控件吧，好像服务器控件，难以实现。

Answer 1

用<Select></select>DropDownList没办法，不知道是不是BUG<select runat="server" id="color">
</select>
for(int i=0;i<10;i++)
{
    color.items.add(.........);
    color.items[i].attributes["style"]="color:#ffffff;background-color:#ffffff";
}

Answer 3

作用定制的方式： DropDownList1.Items.Add(new ListItem("默认","white"));
DropDownList1.Items.Add(new ListItem("红色","red"));
DropDownList1.Items.Add(new ListItem("兰色","blue"));
DropDownList1.Items.Add(new ListItem("紫色","SandyBrown"));
DropDownList1.Items.Add(new ListItem("青色","Aqua"));
DropDownList1.Items.Add(new ListItem("黄色","Yellow"));
for (int i= 0 ;i < DropDownList1.Items.Count;i++)
{
DropDownList1.Items[i].Attributes.Add("style", "background-color:" + DropDownList1.Items[i].Value);
}

用HTML版上的控件，并把此DropDownList1转化成服务器控件使用
<SELECT id="DropDownList1" style="Z-INDEX: 104; LEFT: 256px; WIDTH: 208px; POSITION: absolute; TOP: 72px"
name="DropDownList1" runat="server">
</SELECT>
