Column span

Every node control allows you to span the specified columns count to deliver professional user interface to your users.

To do that, use the ColumnSpan node control property.
Available values:

• 1 – default value to span one column;
• >1 – span the specified columns count;
• -1 – span all available treeview space. In this case the node control`s occupied area is limited only by the treeview`s right border.

Note that you can sequentially span columns by node controls, bound to the same column:
There are two node controls in the same column while they`re span columns <name>+<name> and <name>+<name> sequentially.

Dynamic span

Sometimes you don`t know how many columns a node control needs to span. In this case, Flexible TreeView provides the dynamic span possibility, accessible by enabling the Options.NodeControl.DynamicColumnSpan treeview property.
When it is enabled, treeview raises the NodeControlColumnSpan event every time a node control needs to span columns.

Node control wrapping

The column span feature becomes more useful in cooperation with the Wrap node control feature. It allows you to span columns by a node control and display it under other node controls:
