<Table>.EnumColumn (Function)

In french: <Table>.EnumèreColonne

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 = TABLE_ProductTable.EnumColumn(3)

// Handle the column via a Control variable
pCol is Control
pCol <- TABLE_ProductTable.EnumColumn(3)

// Enumerate all columns found in the Table control "TABLE_ProductTable"
AColumn is Control
FOR nColumn = 1 _TO_ TABLE_ProductTable.Count(toColumn)
AColumnn <- TABLE_ProductTable.EnumColumn(nColumn)
Trace(AColumn.FullName + "//" + AColumn.Title)
END

Syntax

<Result> = <Table control>.EnumColumn(<Column index>)

<Result>: Character string

Column name.
This result can be assigned to a Control variable.
Empty string ("") if <Column index> is equal to the number of columns in the Table control + 1.

<Table control>: Control name

Name of the Table control to be used.

<Column index>: Integer

Index of the column, between 1 and the number of columns 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 <Table>.Count.

Remarks

Use conditions

<Table>.EnumColumn can be used on:

a Table control based on a data file or populated programmatically.
a TreeView Table control based on a data file or populated programmatically.
a single-selection or multiselection control,

Reminder: Multi-selection is not available for "classic" Table controls.

The different types of column indices

There are 2 types of indices for columns:

Index of the visible position: index of the column when the window is executed.
Creation index: index of the column when the control is created in the window editor.

These two types of indices are returned by <Table>.ColumnSubscript.

These indices change if the user moves the columns.

<Table>.EnumColumn uses the column creation index.
