Applies To: Grid

Description

This method is used to set the maximum visible depth of data in rows of a Grid.

The argument to RowSetVisibleDepth is a numeric scalar as follows

[1]

Depth

integer

All rows in the grid that have a value of RowTreeDepth less than or equal to Depth are expanded. Rows with a value of RowTreeDepth greater than Depth are collapsed.

Note: Expanding and Retracting events are not generated when this method is called.

Examples

      'F'⎕WC'Form' 'Grid: TreeView Feature'
      'F.G'⎕WC'Grid'(30 2⍴2/⍳30)
      F.G.RowTreeDepth←30⍴0 1 2 2

      F.G.RowSetVisibleDepth 1

      F.G.RowSetVisibleDepth 99
