Does the UltraWinTree support multiple columns of information?  I didn't think it did.

The purpose of the tool that is being written is to track shipped inventory data back to their source through many changes including producing items from other items (many to one scenario).

Going that number of levels may not happen often, but I would like to try to eliminate this as a potential problem.  My DataSource is a single datatable with approximately 5 columns of data.  It is unlikely that this datatable will have thousands of rows of data.  Most likely 2 to 200 rows at the most.  Note that as I mentioned previously that this is a datatable with a recursive relationship.  Also, the grid's top band would only display the items that have no "parents".

Note that I have tried setting the MaxBandDepth to greater than 100 at design time and it keeps telling me that this is not a valid value.

I appreciate your help with this.

Thank you,

I just looked at the UltraWinTree.  I am more familiar with the Microsoft TreeView control where you cannot have multiple columns.

I will look into this as a possible solution for my issue.
The only concern I have is an issue I had with the UltraGrid control.  When Override.AllowColSizing = Infragistics.Win.UltraWinGrid.AllowColSizing.Synchronized The first column was extremely wide when the MaxBandDepth was 100 (greater than the width of the screen).  Hopefully I will not have the same issue with using the UltraWinTree.

P.S.  I have heard before that the MaxBandDepth could be set to more than 100, but, since this cannot be done in design mode, I thought it was a mistake.  Can you clarify this?

Any other insights or assistance you can provide would be greatly appreciated.  (Net Advantage 13.1)

Thank you for your help.

Yes, it does. If you bind the tree, it will automatically create columns for you in much the same way the grid does.

That's because each band in the grid is indented a little bit more. So when the columns are synchronized, the first band in column 0 is aligned with the first band in column 100 and sine each column is intended, the first columns become huge. the solution to this is simple. Either don't synchronize the columns or set the Indentation on each band to 0.

Sorry, I didn't realize there was a limit on the property. Apparently, it will not accept a value greater than 100. I'm not sure why. That seems like a pretty arbitrary limitation. But like I mentioned previously, anything more than 8 bands is pretty much going to lock up the application, anyway. The DotNet BindingManager simply cannot handle that much depth.

The tree is a little better since it's more efficient and doesn't load the data until the nodes are expanded. But even so, I doubt you will ever be able to get to 100 levels. That's just not realistic in a DotNet Winforms application in my experience.

I am sorry I wasn't clear about my previous post.

I meant to say that I was concerned about having the same behaviour with the UltraWinTree that I get with the UltraGrid with a large # of bands and  Override.AllowColSizing = Infragistics.Win.UltraWinGrid.AllowColSizing.Synchronized.

Do we have any control over how that works, or can the first column scroll independently of the remaining columns, or is there some other thing about it that would allow it to work well?

Either way, I do appreciate your assistance and think that using the UltraWinTree appears to be my best option.

Hopefully I can get it to partially autoexpand like I can with the UltraGrid.

I added code to do that, but it was just testing code so it contains dummy data:

Private Sub UltraGrid1_AfterRowExpanded(sender As Object, e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles UltraGrid1.AfterRowExpanded     For Each Row In e.Row.ChildBands(0).Rows
        If Row.Cells("OwnerTypeID").Value = 1 Then
            If Row.ChildBands(0).Rows.Count = 0 Then
                Row.Expanded = False
                Row.ExpansionIndicator = Infragistics.Win.UltraWinGrid.ShowExpansionIndicator.CheckOnExpand
            End If
        End If
    Next
End Sub

Private Sub UltraGrid1_BeforeRowExpanded(sender As Object, e As Infragistics.Win.UltraWinGrid.CancelableRowEventArgs) Handles UltraGrid1.BeforeRowExpanded     If e.Row.Cells("OwnerTypeID").Value = 1 Then
        If e.Row.ChildBands(0).Rows.Count = 0 Then
            If AutoExpand Then
                e.Cancel = True
            Else
                Me.ItemTrackingData.CostTracking.AddCostTrackingRow(2, "Receiving", "RC140106", 1, "Received", "xyz", "", "", 1, 1, CType(e.Row.ListObject, DataRowView).Row, 0, 0)
            End If
        End If
    End If
End Sub

Am I able to do this type of thing with the UltraWinTree in 13.1?  (Hopefully yes)

I appreciate all of your help with this.
