FindAll does not get all ChildO Objects in List

Hi All,

I need to scroll to an element present in table for WPF application, the value is dynamically provided during run time.

I have below code which runs fine for small listview  as scrollbar moves correctly but does not scroll to elements nearing end of long list.

My list is as below and I scroll using names ( A1, A2 ) etc

A1   1   3  

A2   1   5

S1   1   3  

Q2   1   5



Z7   1   3  

Z82   1   5

Z9   1   3  


Imports SilkTest.Ntf.Wpf
Public Module Main
     Dim _desktop As Desktop = Agent.Desktop
     Public Sub Main()
            Dim iPosition As Double = 0.5
            Dim iSumPosition As Double = 0.0
            Dim sObjlocator As String = "//WPFListView[@automationId='MyListView']"
            Dim sData As String = "Z118"
            Dim sObjSublocator As String = "//WPFToggleButton[@caption='*']"

            Dim rows As IList = _desktop.WPFListView(sObjlocator).FindAll(sObjSublocator)

            Dim sObjExist As Boolean = False

            For Each row As WPFToggleButton In rows
                 Dim sString As String = row.Text
                 Console.WriteLine(sString)     '  <--names
                 If Trim(sString) = sData Then
                        sObjExist = True
                             Exit For
                 iSumPosition += iPosition
                 Console.WriteLine(iSumPosition)  ' <--Position

               _desktop.WPFListView(sObjlocator).ScrollToPosition(iSumPosition, Orientation.Vertical)
                 End If
    End Sub
End Module


Issue: In output below A1 , A10 etc from Console.WriteLine(sString) and  numbers from Console.WriteLine(iSumPosition) ,it works for few objects not in screen  and scrollbar moves vertically down but If my list is large and I need scroll many times then I face issue.

 Scroll bar does not scroll to end for names nearing end of list, if my list is very small then it scrolls down to very last element as well.

In Debug mode I see rows list (Dim rows As IList = _desktop.WPFListView(sObjlocator).FindAll(sObjSublocator)) does not have value (names) for elements nearing end of list.

In output below ,we can see names  & positions are printed initially but in end(for long list) only positions are printed.










Any suggestions will be appreciated 

Additional info:



WPF pre-fill forms settings is : yes
