我正在创建一个RadioButtonList的数据列表,作为每个帖子在数据列表中显示的每个帖子的评分等级,但是当我对一个帖子评分时,所有其他帖子评分相同,您能否告诉我问题在哪里? , 谢谢。 PS:我知道这个问题是在foreach循环谁,如果我删除它,我将无法访问在RadioButtonList或postIDLabel访问数据列表中的控件
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e) {
foreach (DataListItem item in DataList2.Items) {
RadioButtonList RadioButtonList1=(RadioButtonList)item.FindControl("RadioButtonList1");
string choice = RadioButtonList1.SelectedValue;
Label post_IDLabel = (Label)item.FindControl("post_IDLabel");
int post_ID = Convert.ToInt32(post_IDLabel.Text);
int value = Convert.ToInt32(choice);
string connStr = ConfigurationManager.ConnectionStrings["MyDbConn"].ToString();
SqlConnection conn = new SqlConnection(connStr);
SqlCommand cmd = new SqlCommand("rate", conn);
cmd.CommandType = CommandType.StoredProcedure;
string email = Session["email"].ToString();
int course_ID = Convert.ToInt32(Request.QueryString["courseID"]);
cmd.Parameters.Add(new SqlParameter("@course_ID", course_ID));
cmd.Parameters.Add(new SqlParameter("@postID", post_ID));
cmd.Parameters.Add(new SqlParameter("@myemail", email));
cmd.Parameters.Add(new SqlParameter("@rate", value));
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
Response.Write(choice);
}
DataList2.DataBind();
}
我可以看到一些ASPX代码吗? – dotnetstep 2012-01-01 07:06:12
