Submitting Data to Another Page Using ASP.NET

[Dennis E. Jones, Jr.]

I need to post an ASP.NET form between sites for report processing.
Site A contains the asp.net forms and site B contains Java Servlets for
report processing.

All form fields values must be passed to the reporting servlet via http
post method. No parameters can be transmitted by URL. The report must
display in a NEW browser window. Does anyone know how to set a target
using httpwebrequest or is there another alternative?

Hi Dennis,

I've had success doing that using the Webclient class. You need to know
exactly what form field names the target expects.

Not sure about setting it to open in a new page.

Anyway, here's some code to give you an idea:

Sub DoPost()
Dim uriString As String = _
"http://localhost/p4320work/mySpecialPage.aspx"
Dim strGoName As String
strGoName = TextBox1.Text
' Create a new WebClient instance.
Dim myWebClient As New System.Net.WebClient
Dim myNameValueCollection As New _
System.Collections.Specialized.NameValueCollection
myNameValueCollection.Add("go1", strGoName)
myNameValueCollection.Add("Button1", "")
Dim responseArray As Byte() = myWebClient.UploadValues _
(uriString, "POST", myNameValueCollection)
' Response.Redirect("http://msdn.microsoft.com/")
End Sub


Private Sub Button1_Click _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Call DoPost()
End Sub

<form id="Form1" method="post" runat="server">
<P>
<asp:TextBox id="TextBox1" runat="server">test</asp:TextBox></P>
<P>
<asp:Label id="Label1" runat="server">Label</asp:Label></P>
<P>
<asp:Button id="Button1" runat="server" Text="Button"></asp:Button></P>
</form>

Yes, that works...but I still need a solution for the target attribute.
Thanks for your help.

If all you want is a submit button that opens your servlet in a new
window, .NET never comes into play:

<form action="yourServlet.jsp" target="_blank" method="post">
<input type=...>
<input type="submit">
</form>

Retarget your form from the HTML side.

If I do not use .NET, then my server controls also go away.....I guess a
javascript injected into the page on postback would work, but only for
those browsers that support Javascript.
