Unable to sort databound tree nodes...
posted

I have a simple test here and cannot seem to get the nodes to accept sorting when they are bound. I even tried sorting the DataView of the table and binding to that but still no luck. Here is my example. I have 1 ultratree on the form called treeActive and am calling my Override.Sort  =Ascending in the InitializeNode section:

Imports Infragistics.Win

Imports Infragistics.Win.UltraWinTree

Public Class Form1 Public dsFilesToBurn As New DataSet("dsFilesToBurn")

Public tbl As New DataTable("FilesToBurn")

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

CreateDataSet()

AddRows()

treeActive.SetDataBinding(dsFilesToBurn, "FilesToBurn")

treeActive.ExpandAll(ExpandAllType.Always)

'treeActive.Override.SortComparer = New NodeSorter(treeActive.Nodes(1), "Ascending")

'treeActive.Override.Sort = SortType.Ascending

End Sub

Private Sub CreateDataSet()

Dim c As DataColumn

c = New DataColumn("FileName")

With c

.DataType = GetType(String)

End With

tbl.Columns.Add(c)

c = New DataColumn("FileNameGUID")

With c

.DataType = GetType(String)

End With

tbl.Columns.Add(c)

c = New DataColumn("FileParentGUID")

With c

.DataType = GetType(String)

End With

tbl.Columns.Add(c)

c = New DataColumn("FileType")

With c

.DataType = GetType(String)

End With

tbl.Columns.Add(c)

c = New DataColumn("FileID") With c

c.AllowDBNull = False

c.DataType = GetType(Integer)

c.AutoIncrement = True

c.ReadOnly = True

End With

tbl.Columns.Add(c)

tbl.PrimaryKey = New DataColumn() {c}

c = New DataColumn("FilePathCD")

c.DataType = GetType(String)

c.MaxLength = 500

tbl.Columns.Add(c)

c = New DataColumn("FileIcon")c.DataType = GetType(Image)

tbl.Columns.Add(c)

c = New DataColumn("DirGUID")

c.DataType = GetType(String)

c.MaxLength = 50

tbl.Columns.Add(c)

'THIS SHOULD BE SET TO "<SOFTWARE LIBRARY>" IF IT IS FROM THE LIBRARY

'

c = New DataColumn("FilePathLocal")c.DataType = GetType(String)

c.MaxLength = 500

tbl.Columns.Add(c)

c = New DataColumn("CDGUID")c.DataType = GetType(String)

c.MaxLength = 50

tbl.Columns.Add(c)

c = New DataColumn("IsDownloaded")c.DataType = GetType(Boolean)

tbl.Columns.Add(c)
