Trying to open up a form in a new window while passing some values. It is working, but it is client side (My ASP co-worker finally grabbed the reigns and implemented a bit of his ASP magic to open the form and transfer the values.) But it's so messy, and I hate the fact that I have been bested by old technology.
I was doing this client side before, using window.open and transfering the variables in the URL, but I was getting flack for doing that. So I looked at alternatives and found session variables, which you set server side. So now we want to open the form. I tried the following (individually): Response.Redirect("OtherForm.aspx") and Server.Transfer("OtherForm.aspx") Which replaced the original form in the open window instead of a new window.
I spent a lot of time searching for a solution but the answer keeps coming back to "Just inject some JavaScript to open your form." Is there no "normal" way to open a form in ASP.NET. In any case I guess the real question I would like to ask is what is the best way to open a child form from a parent form?
I have a project in VS2008.Net3.5 with a Module1, form1 and form2.
[CODE]
Imports Microsoft.VisualBasic
Module Module1
Public frm1 As form1
Public frm2 As form2
Sub Main()
frm1 = New form1
frm2 = New form2
Application.run(frm1)
End Sub
'A menu sub
Private Sub menuGotoSpecification_Click(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles menuGotoSpecification.Click
frm2.Show()
End Sub
End Module
Public Class form1
Private Overrides Sub Show()
LoadData()
MyBase.Show()
End Sub
End Class
Public Class form2
Private Overrides Sub Show()
LoadData()
MyBase.Show()
End Sub
Private Sub btnDone_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDone.Click
frm1.show()
frm1.refresh()
Me.Hide()
End Sub
End Class[/CODE]
Question:
At the beginning I am opening form1 from sub Main(). Now from the menu I am openning form2. In form2 I am clicking Done button to hide form2 and go back to form1. It works fine in the 1st trial. Keeping form1 open for the 2nd time, I opened form2 from the menu. Now when I Click the Done button 2nd time it just hides up everything. Form1 does not show UP. It just exits the whole application. But in my btnDone event, I have frm1.show().
I'm using DevExpress ASPxGridView edit form, using default edit form. However when I open the edit form in IE6 and click "update" to insert the record, it causes a JavaScript error that says "type" is null or not an object". However it works fine in IE7. I am puzzled and unsure of how to resolve this. Code is below.

View 1 RepliesI have to adjust the existing travel booking form on www.lastminutejoy.de for all the 6 subpages which can be seen in the footer area (royal atlantis, aspendos beach...)
On a certain subpage, e.g. .../aspendosbeach.aspx, the visitor should be able tosearch ONLY everything related to aspendos beach. The style should be like this one: www.delphinpalace.de (on the left)
There you can see that you can search for "flight + hotel" (Flug + Hotel) and "hotel only" (Nur Hotel).
As a result of the search, visitors should see the same style like the one you see on those subpages of lastminutejoy.de.
As you don't have to code from scratch but just have to do some adjustments for all 6 hotels this shouldnt take too long.

View 1 RepliesI have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.

View 4 RepliesI have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.

I am creating a Payment request form that my customers are going to fill out and submit so they get paid I would classifi it as an invoice. Does any one have any examples or point me to a good place to read about creating this type of form and the database tables to support the application?
The form will basically have some fields they will fill in for the header then in the related stuf come charge amounts with there types aka partnumbers of sorts and also the ablity to put in there own types / aka partnumbers and there amounts. I wont be housing any amounts they will supply all the information of payment amounts and types.
is there any reason for me to place the session ID within a form, as a hidden form field?
