我有SqlDataSource和GridView。
我想做的是,虽然问询已经执行(即插入数据),但在数据成功插入之后,应当看上去信息的声音:“成功删除数据”。 我通过使用GridView1_RowDeleted方法解决了这一问题。
现在的问题是,在问询未能执行时,我想赶上错误。 如果问询没有执行,那么就应当看上去“数据没有插入”。
如何这样做? 我对此没有想法。
你们需要帮助。
感谢很多。

You should be able to add a handler for the relevant event: inserted, deleted. Then, in the handler look at the SqlDataSourceStatusEventArgs property Exception
. If it s not null then an
exception has occurred. For example if the selected command threw an
exception:
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.Exception != null)
{
// handle the exception
}
}
