Glossary Item Box

Available in the OPCDA.NET Professional Edition only.
This constructor configures the object for browsing the server into a TreeNode structure and displaying the browse result in a TreeView and a ListView control. Branches are shown in the TreeView control and the items of the selected branch are displayed in the ListView control. In the default BrowseModeOneLevel mode only the root branch is browsed initally. Other branches are browsed when they are the first time selected in the TreeView. The BrowseModeOneLevel property can be set to false before calling the Browse method to force browsing the whole server initally. This is not recommended in typical situations. The browse result is shown alphabetically sorted. The DoNotSort property can be set to true before calling the Browse method to disable sorting.
