Syntax

TreeView Table control: Expanding a branch while specifying the row number Hide the details

TableExpand(<TreeView Table control> [, <Row number>])

<TreeView Table control>: Control name

Name of the TreeView Table control to be used.

<Row number>: Optional integer

Number of the row containing the branch to expand. The branch found in the current row is expanded if this parameter is not specified.
