在我最后一年的项目页面上，我有一个DetailsView，用于更新/编辑GridView。
我有一个密码字段，必须显示哈希密码。
当我在DetailsView中处于"编辑"或"插入"模式并在字段中插入新密码（或编辑字段）时，我希望在GridView/DetailsView中显示密码之前，当然也希望在数据库中插入/更新密码之前，直接对密码进行散列。
我的网格视图&DetailsView都在同一个UpdatePanel中，我正在使用ObjectDataSource。
那是一个部分代码：
<asp:DetailsView ID="DetailsViewSingleUsr" runat="server" Height="50px"
Width="125px" DataSourceID="SingleUserObjectDataSource" DataKeyNames="id"
onitemdeleted="DetailsViewSingleUsr_ItemDeleted"
oniteminserted="DetailsViewSingleUsr_ItemInserted"
onitemupdated="DetailsViewSingleUsr_ItemUpdated" AutoGenerateRows="False"
oniteminserting="DetailsViewSingleUsr_ItemInserting">

我可以访问"ItemInserting"事件中代码后面的密码文本框，代码为：
protected void DetailsViewSingleUsr_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
DetailsView myDetailsView = (DetailsView)sender;
if (myDetailsView.CurrentMode == DetailsViewMode.Insert)
{
Label9.Text = ((TextBox)myDetailsView.FindControl("TextBox4")).Text;
}
}
但是我该如何修改呢？我走对了吗？有什么建议吗？
太多人了！
ListViewInsertEventArgs包含属性Values，您可以在其中找到从控件获得的所有插入值。您可以修改这些数据。例如
e.Values["password"] = "newpassword";
谢谢！我最终得到了这个代码：
protected void DetailsViewSingleUsr_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
e.Values["pass"] = LoginSecurityLogic.Hash_Password_to_MD5(e.Values["pass"].ToString());
}
protected void DetailsViewSingleUsr_ItemUpdating(object sender, DetailsViewUpdateEventArgs e)
{
e.NewValues["pass"] = LoginSecurityLogic.Hash_Password_to_MD5(e.NewValues["pass"].ToString());
}
