Stored procedures
Returns the name of a column found in a Table or Treeview Table control.
Example
// Name of third column found in the "TABLE_ProductTable" control
ResColumnName = TableEnumColumn(TABLE_ProductTable, 3)
Syntax
<Result> = TableEnumColumn(<Table control> , <Column subscript>)
<Result>: Character string
  • Name of column.
  • Empty string ("") if <Column subscript> is equal to the number of columns in the Table control + 1.
<Table control>: Control name
Name of Table control to use.
If this parameter corresponds to an empty string (""), the Table control to which the current process belongs will be used.
<Column subscript>: Integer
Subscript of the column, included between 1 and the number of columns found in the Table control + 1.
A WLanguage error occurs if this parameter is greater than the number of columns found in the Table control + 1.
To find out the number of columns in a Table control, use TableCount.
Remarks

Use conditions

TableEnumColumn can be used on:
  • a browsing or memory control,
  • a single-selection or multiselection control,

The different types of column subscripts

Two types of subscripts are available for the columns:
  • Subscript of the visible position: subscript of the column when running the window.
  • Creation subscript: subscript of the column when creating the control in the window editor.
These two types of subscripts are returned by TableColumnSubscript.
These subscripts are different if the columns have been moved by the user.
TableEnumColumn is using the creation subscript of the column.
