Question

I’m having a problem with ASP.net redirection.

The Copy() method below is called from a javascript button in a grid with ajax and it works fine. It redirects to the Create action of the controller.

<AcceptVerbs(HttpVerbs.Post)> _
Sub Copy(ByVal noDemande As Integer)
    Response.Redirect("/DemandeDeMontage/Create/" & noDemande)
End Sub

The Create action is a page that lets me edit the fields before saving them to the database. When an Id is passed, the fields will be pre-filled with another record’s info (copied info).

<AcceptVerbs(HttpVerbs.Get)> _
Function Create(Optional ByVal id As Integer? = Nothing) As ActionResult
    If (id Is Nothing) Then
        Dim dmd As New DEMND_MONTG
        Return View("Edit", dmd)
    Else
        Dim dmd As ODCT0124_DEMND_MONTG = _dmdMontRep.getDmdById(id)
        dmd.CO_STAT = ModuleCommon.Status.AwaitingSave
        Return View("Edit", dmd)
    End If
End Function

There are no errors in the code above.

When debugging, everything seems to work. The Copy action is called, then Create, and then I can step through the HTML code of the Edit page without any errors.

However, the page will not change! It’s like I’m not redirected at all. The edit page is not shown and I’m stuck on the page displaying the grid with all records I can copy.

Can someone explain why the edit page is not shown? Is there something really obvious I am not seeing?

Answer 1

That was a silly error on my part.

The Copy action was called via AJAX, but I forgot to specify what to do with the html returned from the action.

I’m using window.location = "/DemandeDeMontage/Copy/" + id now instead.
