Custom Choose From List

Question

Hi all,
I am trying to develop a custom choose from list functionality for my addon. I have created two forms first.srf and second.srf .In the key down event of an edittext in my first form i wrote the code for opening the second form
LoadFromXML("Second.srf")
    Private Sub LoadFromXML(ByRef FileName As String)
            Dim oXmlDoc As Xml.XmlDocument
            oXmlDoc = New Xml.XmlDocument
                   Dim sPath As String
            sPath = System.Windows.Forms.Application.StartupPath()
            sPath = sPath.Remove(sPath.Length - 3, 3)
            oXmlDoc.Load(sPath & "" & FileName)
            B1Connections.theAppl.LoadBatchActions(oXmlDoc.InnerXml)
     End Sub
second form is loading very well but my problem is that in the form load event of the second form when i try to access the grid i will get an error message
Item - Invalid Item [66000-3]. Form unique Id "Second", Item Unique Id : "grdItem"
I am using SAP B1 8.8 PL 10, visual Studio 2008 and B1DE 2.1.
Any help
Regards

Hi Sebastian,
Thanks for your reply. i used
Dim oForm As SAPbouiCOM.Form = B1Connections.theAppl.Forms.GetForm("FrmSecond", 0)
to get the form also tried
Dim oForm As SAPbouiCOM.Form
oForm = B1Connections.theAppl.Forms.ActiveForm
but not working . second forms unique id and type are set correctly but the object type is not set because this form is not binded to any UDT.
The OForm objects item count is always 0
Thanks in advance
