在Formview中显示新创建的记录(Display newly created record in Formview)

 我在VS2012上使用asp.net这个表单。 首先，我搜索赞助人，然后去验证该顾客的信息。 该顾客信息显示在ItemTemplate（ReadOnly）中。 如果那不是他们正在寻找的赞助人，那么他们可以添加一个新的赞助人“新按钮”（asp.net代码）。 我能够获得新赞助人的ID（这是PK）。 但是，插入后我无法在表单上显示这个新创建的记录。 它仍然显示正在显示的记录。 由于这是一个formview我没有启用“分页”。  
 是否可以从datasource_inserted事件中调用pageload事件？ 然后我可以传递新的顾客ID进行显示。 我将此ID声明为全局变量？  
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    Dim lvPatronID As String
    lvPatronID = Request.QueryString("value1")
    If lvPatronID = "" Then
        frmPatronView.ChangeMode(FormViewMode.Insert)
    Else
        frmPatronView.ChangeMode(FormViewMode.ReadOnly)
        GvPatronID = lvPatronID
        lblPatronID.Text = GvPatronID
    End If 


Protected Sub PatronDS_Inserted(sender As Object, e As SqlDataSourceStatusEventArgs) Handles PatronDS.Inserted
    NewID = e.Command.Parameters("@PatronID").Value.ToString
    GvPatronID = NewID
End Sub

I have this form on VS2012 with asp.net. First I do search for the patron, then go to verify information for that patron. This patron information is displayed in ItemTemplate(ReadOnly). If that is not the patron they are looking for then they can add a new patron with "New button" (asp.net code). I am able to get the id of the new Patron(which is PK). However I am not able to display this newly created record on the form after inserting. It still displays the record which was on display. Since this a formview I did not enable "Paging". 
Is it possible to call the pageload event from datasource_inserted event? Then I can pass the new patron ID for display. I declared this ID as global variable?  
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    Dim lvPatronID As String
    lvPatronID = Request.QueryString("value1")
    If lvPatronID = "" Then
        frmPatronView.ChangeMode(FormViewMode.Insert)
    Else
        frmPatronView.ChangeMode(FormViewMode.ReadOnly)
        GvPatronID = lvPatronID
        lblPatronID.Text = GvPatronID
    End If 


Protected Sub PatronDS_Inserted(sender As Object, e As SqlDataSourceStatusEventArgs) Handles PatronDS.Inserted
    NewID = e.Command.Parameters("@PatronID").Value.ToString
    GvPatronID = NewID
End Sub

 您需要操纵页面的HTML。  
 我会使用HtmlAgilityPack来提取你想要的部分并将其重写为相同或另一个文件：  
Dim html = File.ReadAllText("c:\temp\htmlTest.htm")
Dim doc = New HtmlAgilityPack.HtmlDocument()
doc.LoadHtml(html)
Dim target = doc.GetElementbyId("target")
If target IsNot Nothing Then
    Dim body = doc.DocumentNode.SelectSingleNode("//body")
    body.RemoveAll()
    body.PrependChild(target)
    Using writer = File.OpenWrite("c:\temp\htmlTest2.htm")
        doc.Save(writer)
    End Using
End If
 
 现在你只需要在WebBrowser加载这个html。  
 如果您想直接从Internet / Intranet获取HTML：  
Dim client As New HtmlAgilityPack.HtmlWeb()
Dim doc As HtmlAgilityPack.HtmlDocument = client.Load("http://yoururl.com")
' rest is the same as above(without doc.LoadHtml) '

You'll need to manipulate the HTML of the page. 
I would use HtmlAgilityPack to extract the part you want and rewrite it to the same or another file: 
Dim html = File.ReadAllText("c:\temp\htmlTest.htm")
Dim doc = New HtmlAgilityPack.HtmlDocument()
doc.LoadHtml(html)
Dim target = doc.GetElementbyId("target")
If target IsNot Nothing Then
    Dim body = doc.DocumentNode.SelectSingleNode("//body")
    body.RemoveAll()
    body.PrependChild(target)
    Using writer = File.OpenWrite("c:\temp\htmlTest2.htm")
        doc.Save(writer)
    End Using
End If
 
Now you just have to load this html in the WebBrowser. 
If you want to get the HTML directly from internet/intranet: 
Dim client As New HtmlAgilityPack.HtmlWeb()
Dim doc As HtmlAgilityPack.HtmlDocument = client.Load("http://yoururl.com")
' rest is the same as above(without doc.LoadHtml) '
