Apply Pagination to TreeView Results

Large projects often display thousands of items in the tree view, which slows down the display of the result and makes scrolling and viewing more difficult for users.
Visual Expert users can apply pagination to a long list of items in the TreeView to display results faster and make them easier to read and navigate.

How does TreeView Paging improve Data Loading?

Let’s consider a long list of items to be displayed in TreeView.
For instance: All System Functions present in your PB application.

  • Go to PowerBuilder System Objects > Function in the [Main View].
    A list of all system function components will be available to browse at once.
    PB System Objects
  • Enable TreeView Paging as explained above.
    Visual Expert will split the result in groups of 100 components.
    PB System Objects Function list
  • Click on TreeView Paging Down Arrow to reach the last item of the first result group instantly.
    TreeView Paging List - Last Item
