View Mode

To view this method in the Object Browser panel and in other panels and dialogs, activate the Advanced view mode.


The method has the following parameters:


Specifies the zero-based index of the desired data row. The first visible row has index 0, the second - 1, and so on. The index of the last visible row is wRowCount - 1.


Specifies whether to expand or to collapse the row.

Result Value



If the specified row is not found, ExpandRow fails and posts an error message to the log.

The script recorder recognizes mouse clicks on the “+” buttons within rows, and records the ExpandRow command.

To collapse the row, you can either call the CollapseRow action or call ExpandRow with the Expand parameter set to False.
