Columns. Get started.

Flexible TreeView may show nodes either within an unlimited width or within columns. You can add or remove columns using the Columns property, either in the Visual Studio designer or programmatically.

Example:

// add column.
TreeColumn col = new TreeColumn();    // or new TreeColumn(“Column title”, 100);
col.Text = “Column title”;
col.Width = 100;
tree.Columns.Add(col);
 
// attach node control.
NodeTextBox tb = new NodeTextBox();
tb.AttachToColumn(col);               // or tb.ColumnId = col.Id;
tb.AttachTo(tree);
 
// add node.
Node node = new Node("test");
node.AttachTo(tree);

Node controls binding

Every column shows only those node controls, that are bound to it and visible. To bind a node control to the column, set the ColumnId node control property to a target column Id property value or set the Column property to a column instance.

Visibility

By default, a newly added column is visible in the treeview, but you can hide it by disabling the Visible property. When column visibility changes, the treeview raises the ColumnVisibilityChanged event.

Override column icons

By default, Flexible TreeView uses system or Office2007 theme column icons but you are able to override them by using the Images treeview property.
