No I didn't. Apparently I stumped the infragistics support people on this one. I ended up writing some code to enumerate all the columns in the grid, let them choose which ones to show and hide, and then saving that off to a database.

In case anyone's interested, here's a basic example I slapped together that seems to work.You'll need to change it to save to a DB or whatever.

Partial Class _Default
    Inherits System.Web.UI.Page

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not IsPostBack Then
            Dim dt As System.Data.DataTable = New System.Data.DataTable("Table1")
            dt.Columns.Add("Col1", GetType(String))
            dt.Columns.Add("Col2", GetType(String))
            dt.Columns.Add("Col3", GetType(String))
            dt.Columns.Add("Col4", GetType(String))
            dt.Columns.Add("Col5", GetType(String))
            Dim random As Random = New Random()
            Dim i As Integer
            For i = 0 To 5 - 1
                Dim rowdata(4) As String
                Dim j As Integer
                For j = 0 To 5 - 1
                    rowdata(j) = random.Next(1000).ToString()
                Next
                dt.Rows.Add(rowdata)
            Next
            Me.UltraGrid1.DataSource = dt
            Me.UltraGrid1.DataBind()
        End If
    End Sub

    Protected Sub SaveSettings_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SaveSettings.Click
        Dim gl As New GridLayout
        For Each c As Infragistics.WebUI.UltraWebGrid.UltraGridColumn In Me.UltraGrid1.DisplayLayout.Bands(0).Columns
            gl.add(New ColumnLayout(c.Header.Caption, c.Header.RowLayoutColumnInfo.OriginX))
        Next
        Session("layout") = gl
    End Sub

    Protected Sub LoadSettings_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoadSettings.Click
        Dim gl As GridLayout = TryCast(Session("layout"), GridLayout)
        If Not (gl Is Nothing) Then
            Dim col As Infragistics.WebUI.UltraWebGrid.UltraGridColumn
            For Each cl As ColumnLayout In gl
                col = Me.UltraGrid1.Columns.FromKey(cl.Key)
                col.Move(cl.PositionIndex)
            Next
        End If

    End Sub
End Class



Public Class ColumnLayout
    Public Sub New(ByVal key As String, ByVal index As Int32)
        Me.Key = key
        Me.PositionIndex = index
    End Sub

    Private m_Key As String
    Public Property Key() As String
        Get
            Return m_Key
        End Get
        Set(ByVal value As String)
            If (m_Key <> value) Then
                m_Key = value
            End If
        End Set
    End Property

    Private m_PositionIndex As Integer
    Public Property PositionIndex() As Integer
        Get
            Return m_PositionIndex
        End Get
        Set(ByVal value As Integer)
            If (m_PositionIndex <> value) Then
                m_PositionIndex = value
            End If
        End Set
    End Property

End Class



Public Class GridLayout
    Inherits CollectionBase

    Public Sub add(ByVal val As ColumnLayout)
        Me.List.Add(val)
    End Sub
End Class

 I didn't end up handling the column order. However, I believe if you get/set these properties it will work:

                      ParentGrid.Columns.FromKey(key).Footer.RowLayoutColumnInfo.OriginX
                      ParentGrid.Columns.FromKey(key).Header.RowLayoutColumnInfo.OriginX

How do you handle the changes in column order? Or do you?

 Thanks,
