}
TreeListViewSubItem subItem = null;
for (int j = 0; j < this.treeListView1.Columns.Count; j++)
{
subItem = new TreeListViewSubItem();
}
switch (this.treeListView1.Columns[j].ContentType)
{
default:
subItem.Text = "Item " + sufix + j.ToString();
break;
}
parentNode.SubItems.Add(subItem);
private void CreateSubNodes(TreeListViewNode parentNode, int level, string sufix)
{
// In this example only two levels in hierarchy are allowed
if (level == 2)
return;
else
{
// Create child nodes for specified node
TreeListViewNode node = null;
for (int i = 0; i < 2; i++)
{
node = new TreeListViewNode("Node " + sufix + i.ToString());
nodeIndex++;
}
}
}
// Create subitems for this node
CreateSubItems(node, sufix + i.ToString());
// Create child nodes for this node
CreateSubNodes(node, level + 1, sufix + i.ToString());
parentNode.Nodes.Add(node);
The above code will create two columns with several nodes and two subitems in each node. All
data in column will be labels.
How to show custom images in column
By changing a little bit above code sample, we will set the second column to show images. The
changes are marked in Red:
[VB]
Private Sub InitList(ByVal sender As Object, ByVal e As EventArgs)
' Create three columns with header and footer description
Dim column As TreeListViewColumn = Nothing
For j As Integer = 0 To 1
column = New TreeListViewColumn("Header " & j.ToString(), "Footer " &
j.ToString())
