Remarks

The columnID argument identifies the column for which to get or set a value. The following objects and values can be passed as column identifiers:

TreeListColumn object
TreeListColumn.FieldName value
TreeListColumn.AbsoluteIndex value
System.Data.DataColumn object (when TreeList.DataSource represents the System.Data.DataView or System.Data.DataTable source)

The next example demonstrates how to access a focused node value in the column which is identified by the TreeListColumn.AbsoluteIndex property set to 0.

Two ways are provided to perform this operation: via the TreeListNode.Item property and TreeListNode.SetValue method.

C#
VB.NET

csharp

//first method
treeList1.FocusedNode.SetValue(0, "new value");
//second method
treeList1.FocusedNode[0] = "new value";

'first method
TreeList1.FocusedNode.SetValue(0, "new value")
'second method
TreeList1.FocusedNode(0) = "new value"
