在插入模式下，插入/提交新记录不适用于DetailsView
[英]Insert/submit new record not working on detailsview in insert mode
问题描述
I have a detailsview that is always in insert mode. 
我有一个DetailsView始终处于插入模式。 The user will always only enter new records never edit or view. 用户将始终只输入从未编辑或查看的新记录。 The probelm I am having is when i press the insert button(to add a new record after the fields have been filled out) nothing happens. 当我按下插入按钮（在字段填写完毕后添加新记录）时，我遇到的问题没有任何反应。 The record is not entered and the page shows no change. 未输入记录，页面显示没有变化。
I have been working on this detailsview for weeks and not made much progress because of these problems with postback and submitting values. 我已经在这个detailsview上工作了数周，由于回发和提交值存在这些问题，因此没有取得太大进展。 Any help is appreciated 任何帮助表示赞赏

I would try and remove the other DataBind() methods in your ItemInserted Event handler . 我将尝试删除ItemInserted Event handler中的其他DataBind()方法。 I believe you only want to DataBind() the detailsview. 我相信您只想使用DataBind() detailsview。

protected void Page_Load(object sender, EventArgs e) { 受保护的无效Page_Load（对象发送者，EventArgs e）{
if (!IsPostBack) { DetailsView1.DataBind(); 如果（！IsPostBack）{DetailsView1.DataBind（）; } } }}
delete this DetailsView1.DataBind(); 删除此DetailsView1.DataBind（）;
