Windows Mobile
// Expands the selected branch in the TreeView Table control
TVT_ScheduleTable.Expand()
Windows Mobile
// Expands the entire TreeView Table control
TVT_ScheduleTable.Expand(1)
// Equivalent to: TVT_ScheduleTable.ExpandAll()

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

<TreeView Table control>.Expand([<Row number>])
<TreeView Table control>: Control name
Name of TreeView Table control to use.
<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.
Windows Mobile

TreeView Table control: Expanding a branch while specifying its name Hide the details

<TreeView Table control>.Expand([<Branch name>])
<TreeView Table control>: Control name
Name of TreeView Table control to use.
<Branch name>: Optional character string (with quotes)
Name of branch to expand. This parameter has the following format:
"<Name of root>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>"
A WLanguage error occurs if this parameter does not correspond to an existing branch.
The branch found in the current row is expanded if this parameter is not specified.

Table control with breaks: Expanding a break Hide the details

<Table control>.Expand([<Row number> [, <Name of break>]])
<Table control>: Control name
Name of Table control to use.
<Row number>: Optional integer
Number of the row whose break will be expanded. This number must correspond either to the number of the current row, or to the number of the first row of the break to expand. If this parameter is not specified, the break of current row is collapsed.
<Name of break>: Optional character string
Name of break to expand. This parameter must be specified in case of nested breaks. It is used to define the break that will be expanded. By default, no break is expanded if the breaks are nested.
Remarks

Use conditions

<Table>.Expand can be used on:
  • Windows Mobile a TreeView Table control.
  • a memory Table control.
  • a browsing Table control loaded in memory.
This function cannot be used on the browsing Table controls (direct access).

Branch to expand

<Table>.Expand has no effect:
TreeView Table controlTable control with breaks
  • if the branch to collapse is not found.
  • if the branch to collapse is a leaf.
  • if the branch to collapse is already collapsed.
  • if the Table control contains no break.
  • if the Table control contains several breaks and if the break to expand is not specified.
  • if no row is selected in the Table control and if <Row number> is not specified.

Remarks for the TreeView Table controls:
  • If <Row number> or <Branch name> corresponds to the branch contained in the first row, the entire hierarchy of the TreeView Table control is expanded (equivalent to <Table>.ExpandAll).
  • Versions 19 and later
    During the call to <Table>.Expand, if the specified branch includes a procedure associated by ..AddChildDelayed, this procedure will be run.
    New in version 19
