DropDownList属性(C#，ASP.net) [英] DropDownList Attributes (C#, ASP.net)

问题描述

for(int i=1; i<=10; i++)
{
    li.Items.Add(new ListItem("Item" + i));
    if (i%2 == 0)
    {
       li.Items[i-1].Attributes["itemType"] = "Even";
    }
    else
    {
       li.Items[i-1].Attributes["itemType"] = "Odd"";
    }
}

我已经为li DropDownList的每个列表项添加了一个名为"itemType"的属性.但是我在下拉列表中选择其他项目后，无法获得分配给该属性的值.我认为，更改SelectedItem时，属性"itemType"也将被删除.

请帮我解决这个问题.
谢谢！

I''ve added each list item of the li DropDownList an attribute called "itemType". But I ''m not able to get the value assigned to that attribute after I select a different item in li Dropdownlist. I think the attribute "itemType" is also getting deleted when the SelectedItem is changed.

Please help me solving this.
Thank you!
