在asp.net 中,我用下面方法初始化下拉框

public string[] arrState = {"AL", "AK", "AR", "AZ",
"CA", "CO", "CT", "DE", "FL", "GA", "HI", "ID", "IL",
"IN", "IA", "KS", "KY", "LA", "MA", "ME", "MD", "MI",
"MN", "MO", "MS", "MT", "NC", "ND", "NE", "NH", "NJ",
"NM", "NV", "NY", "OH", "OK", "OR", "PA", "RI", "SC",
"SD", "TN", "TX", "UT", "VA", "VT", "WA", "WI", "WY"};
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
state.Items.Clear();
contacttype.Items.Clear();
for(int i=0;i<arrState.Length;i++)
state.Items.Add(arrState[i]);
....................
.........................
}
每次我选中下拉框后点击按钮提交,下拉框选中的值又变成默认的(一般是第0个item);我知道每次点击按钮时,Page_Load()重新执行...我没办法取得选中的下拉框值!!!!有什么办法可以解决吗?

contacttype是另一个下拉框,在这里可以先不管.我的问题是,点选下拉框选中一个选项后,单击按钮,下拉框的值又变成初始值,并且从下拉框中得到的值是初始值,不是点选后的值.

把初始化的代码放到
#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//下拉框初始化代码

}
目前可以解决问题.健壮性没有检验..
