如何让我的Search控制器doSearch()内部具有调用getTitles()功能的Titles控制器功能?
我有一个名为TopicTree.ascx.cs的文件,我试图输出编码的字符串,如下所示:
string subject = reader.IsDBNull(0) ? string.Empty : reader.GetString(0);
string topic = reader.IsDBNull(1) ? string.Empty : reader.GetString(1);
subject = subject.Trim();
topic = topic.Trim();
string en_subject = Server.HtmlEncode(subject);
string en_topic = Server.HtmlEncode(topic);
string output = string.Format("<li><a href=\"searchresults.aspx?type=topics&subject={1}&topic={2}\" style=\"cursor: pointer;\">{0}</a></li>", topic, en_subject, en_topic);

但是当我实际看到屏幕上的输出时,它没有被编码.怎么了?

如何更改后面代码中的列表项?我想在它们呈现给用户之前做一个Html_Decode并修剪它们?
DataBind代码是:
StringBuilder sql = new StringBuilder();
// Define sql
sql.Append("SELECT DISTINCT datasource ");
sql.Append("FROM meta ");
sql.Append("WHERE datasource != '' ");
sql.Append("ORDER BY datasource ASC ");
IDataReader reader = SqlHelper.GetDataReader(sql.ToString());
ddlDatasources.DataSource = reader;
ddlDatasources.DataBind();

我在客户端的生产服务器上发生了 SQL 异常(我在其中几乎没有权限)。
我无法在本地复制问题,但是有什么好的方法可以获取并找出正在调用哪个 sql 异常以及使用哪个 sql 吗?我可以重新部署并有权更改源代码。

我有以下代码来获取UIScrollView到达其内容视图结束时的事件:
- (void) scrollViewDidEndDecelerating:(UIScrollView *) scrollView
{
float currentEndPoint = scrollView.contentOffset.y + scrollView.frame.size.height;
// CGPoint bottomOffset = CGPointMake(0, scrollView.contentSize.height - scrollView.bounds.size.height);
// [scrollView setContentOffset:bottomOffset animated:NO];
if (currentEndPoint >= scrollView.contentSize.height)

我注意到当我滚动到底部时它会撞到它并反弹回来.
如果我添加这个:
CGPoint bottomOffset = CGPointMake(0, scrollView.contentSize.height - scrollView.bounds.size.height);
[scrollView setContentOffset:bottomOffset animated:NO];

然后滚动回到底部.
是否有任何方法让它保持在底部没有"反弹",因为一旦它击中底部,阻止它移动.
谢谢.
