How to add existing column collection
If you have some predefined set of columns, and you want this set as a whole to be added to the
TreeListView control, you can use AddRange method:
[VB]
Imports LidorSystems.IntegralUI.Lists
. . .
Dim columns As TreeListViewColumn() = New TreeListViewColumn(2) {}
For i As Integer = 0 To columns.Length - 1
columns(i) = New TreeListViewColumn("Header " & i.ToString(), "Footer " &
i.ToString())
Next
Me.treeListView1.Columns.AddRange(columns)
[C#]
using LidorSystems.IntegralUI.Lists;
. . .
TreeListViewColumn[] columns = new TreeListViewColumn[3];
for (int i = 0; i < columns.Length; i++)
columns[i] = new TreeListViewColumn("Header " + i.ToString(), "Footer " +
i.ToString());
this.treeListView1.Columns.AddRange(columns);
How to fix column to the left or right side of the control
There are situations when you need some column(s) to be fixed on left or right side of the
TreeListView control, while other columns remain scrollable. In this way the data in fixed columns
will always remain visible, while scrolling the remaining area.
