In the attached example Shift-select doesn' work correctly after selecting a row by code.
Situation: Tree with 100 entries. SelectType is ExtendedAutoDrag. Before searching the SelectType is changed to Single so only the one found row is selected.

- Select Row #5
- Enter 20 in text field and press search button
- Messagbox shows, that row 20 is selected and active
- Shift click in row 22

Expected behaviour: rows 20 - 22 are selected
Experienced behaviour: rows 5 - 22 are selected.

This is the search code:
Me.ugdTcodes.DisplayLayout.Override.SelectTypeRow = Infragistics.Win.UltraWinGrid.SelectType.Single

        For Each uRow As Infragistics.Win.UltraWinGrid.UltraGridRow In Me.ugdTcodes.Rows
            If uRow.Cells("Tcode").Value.toupper = Me.txtSearchStringGrid.Text.ToUpper Then
                uRow.Activate()
                uRow.Activated = True
                uRow.Selected = True
            Else
                uRow.Selected = False
            End If
        Next
        Me.ugdTcodes.DisplayLayout.Override.SelectTypeRow = Infragistics.Win.UltraWinGrid.SelectType.ExtendedAutoDrag

Are there more properties of the tree/rows to be taken into account or is this an error?
