Editor There are two ways to create objects in TreeListView control: during design-time or programmatically. In design-time you can use the TreeListView Editor by right-clicking on the TreeListView control. The form will appear in which you can add, remove, change the columns, nodes or subitems. In order to create columns, nodes and subitems programmatically, you can use the following code: [VB] ' Assuming that TreeListView control exist Private Sub InitList() ' Suspend the layout logic for the TreeListView control Me.TreeListView1.SuspendUpdate() ' Create three columns with header and footer description Dim column As TreeListViewColumn = Nothing For j As Integer = 0 To 2 column = New TreeListViewColumn("Header " & j.ToString(), "Footer " & j.ToString()) Me.treeListView1.Columns.Add(column) Next ' Create root nodes Dim node As TreeListViewNode = Nothing For i As Integer = 0 To 4 9
