Notes on the tree node ID (GUID) and index series

This topic refers to the nodeIdOrIndexSeries parameter.

  • When building nodes, WinStudio assigns a unique ID to each node. This is its GUID (globally unique identifier). A node's GUID value can be obtained through various APIs, returning an XML document string. GUID string values can be used to explicitly identify tree nodes.
  • Assume you have these tree nodes:

  • Each node can also be represented by a node index series (comma-separated numeric values to indicate the node index at each level).

    For example, for node "XYZ" in the above tree, found at Level 2, Index 0, the node index series is 2,0 (index 2 at Level 0; index 0 at Level 1).
