[CLOSED] [1.0] Problem with Multifield.Fields.Remove component

[PoloTheMonk]

Hi,
I create runtime a panel "pnlfiltro_campo" and inside it a multfield "multif_campo"; I add two fields: an ext.net.textfield and an ext.net.button.

The problem is on RemovePanel ("pnlfiltro_campo") 's function.

I run my page and my panel ("pnlfiltro_campo") is displayed correctly but when I click on "remove panel"'s button after few minutes appears a msg "Do you want to interrupt script? Internet explorer is slowed down by one of the script of the page; computer could not respond". If I confirm stopping script in my panel "pnlfiltro_campo" disappear textfield component but not button component, so I think that the problem is when page try to remove button...

The same problem occours if in multifield I add an ext.net.datafield instead of ext.net.button component.

Differently, if in multifield I add an ext.net.combobox instead of ext.net.button component, it works perfectly!!

Here the code:

Public Sub CreatePanel() 
    Dim Filtro As New Panel    
    Filtro.ID = "PANELFILTRO_CAMPO"
    Filtro.EnableViewState = "false"    
    Filtro.Header = False
    Filtro.Icon = Icon.BulletCross
    Filtro.Draggable = True
    Filtro.AutoWidth = False
    Filtro.AutoHeight = False

    Dim Pnl As Panel = AddCampo()
    Pnl.ID = "PNLFILTRO_CAMPO"
    Filtro.Items.Add(Pnl)

    'FiltriColonna is defined in markup and it is an Ext.Net.PortalColumn of "PortalFiltri" ext.net.portal
    FiltriColonna.Items.Add(Filtro)
End Sub



Public Function AddCampo() As Panel
    Dim Layout As New MultiField
    Layout.ID = "MULTIF_CAMPO"


    Dim Tb As New Ext.Net.TextField
    Tb.ID = "FILTRO_CAMPO"


    Dim BttnCerca As New Ext.Net.Button
    BttnCerca.Icon = Icon.Zoom
    BttnCerca.ID = "BTTN_PAGINA_CAMPO"
    BttnCerca.DirectEvents.Click.ExtraParams.Add(New Parameter("CAMPO", 1))
    BttnCerca.DirectEvents.Click.EventMask.ShowMask = True
    BttnCerca.DirectEvents.Click.EventMask.Msg = "Caricamento dati in corso..."
    AddHandler BttnCerca.DirectEvents.Click.Event, AddressOf BottoneApriFiltroPagina


    Layout.Fields.Add(Tb)


    Layout.Fields.Add(BttnCerca)


    Dim Pnl As New Panel


    Pnl.Items.Add(Layout)


    Return Pnl
End Function




Public Sub RemovePanel()    'first test
    Dim Pannello As Ext.Net.Panel
    Pannello = PortalFiltri.FindControl("PANELFILTRO_CAMPO")



    Dim Parent As PortalColumn = Pannello.Parent


    If Not IsNothing(Pannello) Then
        Parent.Remove(Pannello.ClientID)
        Parent.DoLayout()
    End If
End sub

Public Sub RemovePanel()    'second test
    Dim Contenitore As Ext.Net.Panel
    Contenitore = PortalFiltri.FindControl("PNLFILTRO_" & Campo)


    Dim Layout As New MultiField
    Layout = Contenitore.FindControl("MULTIF_" & Campo)


    If Not IsNothing(Layout) Then
        Dim Bottone As New Ext.Net.Button
        Bottone = Contenitore.FindControl("BTTN_PAGINA_" & Campo)


        If Not IsNothing(Bottone) Then
            Bottone.DirectEvents.ClearDirectEvents()
            Layout.Fields.Remove(Bottone)
        End If
    End If


    Layout.Fields.RemoveRange(0, Layout.Fields.Count)


    Contenitore.Remove(Layout.ClientID)


    Contenitore.RemoveAll()


    Contenitore.DoLayout()
End Sub

I try to remove panel in different ways but with no results.

Thanks in advance

Hi,

Fixed. Please update from SVN
Today we added CompositeField and marked MultiField as obsolete. Therefore I recommend replace all MultiField instances by CompositeField
