我用了Ajxa中的UpdatePanel 其它什么都没有，它却报出一个Sys.ScriptManger..后面的有点忘记了，最后是一个500错误，
无言
我的后台代码是这样的、
我感觉是回传问题，就是找不到···急··
C# code:
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (txtReviewContent.Text != "")
{
this.txtReviewContent.Text += "<img src='../images/" + RadioButtonList1.SelectedItem.Value.ToString() + ".gif'></img>";
}
else
{
this.txtReviewContent.Text = "<img src='../images/" + RadioButtonList1.SelectedItem.Value.ToString() + ".gif'></img>";
}
}
protected void btnUpdate_Click(object sender, EventArgs e)
{
UserInfo us=(UserInfo)Session["user"];
int MovieId;//null
string ReviewContent;
string UserId=null;
string ReviewTime;
string adminRevert;//null
string remarkOnType;
MovieReview moive = new MovieReview();
MovieInfo mm = new MovieInfo();
moive.User=us;
mm.MovieId = 1025;
moive.Movie = mm;
moive.ReviewContent = txtReviewContent.Text.ToString();
moive.ReviewTime = DateTim
