I have been fighting with this code for 3 days. I got everything to work....except its a bit glitchy as of right now and I can't figure out why. I am sure it is simple. They basic concept is something like this:

OFFICE
[txtbox] [txtbox] [txtbox] [label]
+add row

BUSINESS
[txtbox] [txtbox] [txtbox] [label]
+add row

SOFTWARE:
[txtbox] [txtbox] [txtbox] [label]
+add row

I add a row using AJAX control, viewstate, Page_Init and all the correct methods... the only thing is... If I hit Add row for Office it will...then if I hit add row for software it adds one to office...then i hit software again and it will add down to software. Its like its one off somewhere in the logic... i cant find it...its driving me insane... PLEASE help :) here is my code and my markup:

Why don't you do Line 27-29

add_office_rows()
add_business_rows()
add_software_rows()

with ifs or in Button press why do you do them all?

Well there is too much code to try and debug and see what is wrong.

I am not sure what you mean, but I want to make sure you know what I mean.

Can't you do

if  software then do 
    add_software_rows()
else if business 
    add_business_rows()
else if office
    add_office_rows()

If I dont run those three functions in init then the rows that have been added prior to this postback will not populate or even be there.

MichaelWClark 0 Junior Poster · Answer 2 · 2010-06-28T19:06:50+00:00

no these functions must run every time regardless if that button was pushed or not. If they are not run then the rows that were added previously will not render. As you see in Page_Load I incriment the counter to tell me how many rows to render which is doing the same thing you have in mind..my way just keeps the viewstate intact.

here is a more brief code for you to hopefully be able to help debug. This is just an example script but esentially does...or needs to do the same thing.

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Session("tb_num") += 1
    End Sub

    Public Function add_text_box() As Double
        For z = Session("tb_num") To 0 Step -1
            Dim x As New TextBox
            form1.Controls.Add(x)
            x.ID = "tb" + z.ToString
            Label1.Text = Session("tb_num")
        Next
    End Function

    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Session("tb_num") = Nothing Then
            Session("tb_num") = 1
        End If
        add_text_box()
    End Sub

    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
        For z = Session("tb_num") To 0 Step -1
            Dim tb As TextBox = New TextBox
            tb.ID = "tb" + z.ToString
            Label1.Text += tb.Text
        Next

    End Sub

    Public Function find_control(ByVal cnt As Control) As Double
        For Each x As Control In cnt.Controls
            If TypeOf x Is HtmlInputControl Then
                Label1.Text += CType(x, HtmlInputControl).Value
                CType(x, HtmlInputControl).Disabled = True


            End If
            If x.HasControls Then
                find_control(x)
            End If
        Next
    End Function
End Class
