I want to retrieve data from controls in the requested page to other page by
using request.form(control name) but this is not working for me.I tried both response.redirect and also server.transfer for redirect to new page but it is not working for both the commands.

Re: request.form is not working in asp.net

Here's an example. Lets say you have page1.aspx with a textbox control. You want a user to click a next button, transfering to page2.aspx and writting the text out on that page.

The code for button click on page1.aspx

ASP.NET Syntax (Toggle Plain Text)
Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click
        Dim context As HttpContext = HttpContext.Current
        context.Items.Add("strFirstName", TextBox1.Text)
        Server.Transfer("page2.aspx", True)
    End Sub
Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click
        Dim context As HttpContext = HttpContext.Current
        context.Items.Add("strFirstName", TextBox1.Text)
        Server.Transfer("page2.aspx", True)
    End Sub

The page_load for the page2.aspx:

ASP.NET Syntax (Toggle Plain Text)
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim context As HttpContext = HttpContext.Current
        Response.Write("Your First Name is: " & context.Items("strFirstName"))
    End Sub
 
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim context As HttpContext = HttpContext.Current
        Response.Write("Your First Name is: " & context.Items("strFirstName"))
    End Sub

Re: request.form is not working in asp.net

I am having the same problem with a slight difference. I hope someone can help.
In my aspx page I have the following:

ASP.NET Syntax (Toggle Plain Text)
 <script>
  sub blah()
   For intloop = 0 To (intFieldCount - 1)
    Dim oCell As New TableCell()
    strDateLink = "<input name='" & strInputName & "' type='text' value='" & dtClosureDate.ToLongDateString & "' size='33' rows='1' class='ltk' style='border:none'  />"
    oCell.Text = strDateLink
    oRow.Cells.Add(oCell)
Next
  end sub
  </script>
 <script>
  sub blah()
   For intloop = 0 To (intFieldCount - 1)
    Dim oCell As New TableCell()
    strDateLink = "<input name='" & strInputName & "' type='text' value='" & dtClosureDate.ToLongDateString & "' size='33' rows='1' class='ltk' style='border:none'  />"
    oCell.Text = strDateLink
    oRow.Cells.Add(oCell)
Next
  end sub
  </script>

A you can see I am building <input> dynamically. Let’s say that the above loops 20 times, each with a different name for the dynamic <input>. How can I transfer these 20 values?
I have the following control in the body of the page.

ASP.NET Syntax (Toggle Plain Text)
 <asp:Button id="btnPreCloseSumbit" OnClick="TransferFormValues" Text="Submit " runat="server"/>
 <asp:Button id="btnPreCloseSumbit" OnClick="TransferFormValues" Text="Submit " runat="server"/>

Which calls

ASP.NET Syntax (Toggle Plain Text)
Sub TransferFormValues(Source As Object, E As EventArgs)
    Dim context As HttpContext = HttpContext.Current
    context.Items.Add("strFirstName", TextBox1.Text)
    Server.Transfer("body_date_closures_test_output.aspx", True)
 End Sub
Sub TransferFormValues(Source As Object, E As EventArgs)
    Dim context As HttpContext = HttpContext.Current
    context.Items.Add("strFirstName", TextBox1.Text)
    Server.Transfer("body_date_closures_test_output.aspx", True)
 End Sub

I guess I don’t understand how to transfer the form input that has a dynamic name.

ASP.NET Syntax (Toggle Plain Text)
Sub Page_Load(Source As Object, E As EventArgs)
    response.Write("hello<br><br>")
    Dim context As HttpContext = HttpContext.Current
    Response.Write(context.Items("strFirstName"))
    response.Write("<br><br>...")
End Sub
Sub Page_Load(Source As Object, E As EventArgs)
    response.Write("hello<br><br>")
    Dim context As HttpContext = HttpContext.Current
    Response.Write(context.Items("strFirstName"))
    response.Write("<br><br>...")
End Sub

Re: request.form is not working in asp.net

it's okay. i just relised that i had been going about this the wrong way. i am able to use the request.form("id") instead of redirect and request.
