Imports Infragistics.Win.UltraWinTree Imports Infragistics.Win
This topic shows you how columns can be added to WinTree™ in Freeform style. In Freeform style each and every row can have a different set of columns and above each column’s cell data, column headers can be displayed. Thus the freeform style allows you to create a separate, distinct schema on a node-by-node basis for heterogeneous data.
In this example each row displays different columns with different data. It is assumed that you have an UltraTree dropped onto your form.
Before you start writing any code, you should place using/imports directives in your code-behind so you don’t need to always type out a member’s fully qualified name.
In Visual Basic:
Imports Infragistics.Win.UltraWinTree Imports Infragistics.Win
In C#:
using Infragistics.Win.UltraWinTree; using Infragistics.Win;
Write the following code in the form load event.
